This too stands contrary to the message of this chapter: if you have identified a sufficient set of deconfounders in your diagram, gathered data on them, and properly adjusted for them, then you have every right to say that you have computed the causal effect X Y (provided, of course, that you can defend your causal diagram on scientific grounds). The textbook approach of statisticians to confounding is quite different and rests on an idea most effectively advocated by R. A. Fisher: the randomized controlled trial (RCT). Fisher was exactly right, but not for exactly the right reasons. The randomized controlled trial is indeed a wonderful invention—but until recently the generations of statisticians who followed Fisher could not prove that what they got from the RCT was indeed what they sought to obtain. They did not have a language to write down what they were looking for—namely, the causal effect of X on Y.

Of course, statisticians already knew of one excellent way to establish causation in a more general sense: the randomized controlled trial (RCT). But such a study would be neither feasible nor ethical in the case of smoking. How could you assign people chosen at random to smoke for decades, possibly ruining their health, just to see if they would get lung cancer after thirty years? It’s impossible to imagine anyone outside North Korea “volunteering” for such a study. Without a randomized controlled trial, there was no way to convince skeptics like Yerushalmy and R. A. Fisher, who were committed to the idea that the observed association between smoking and lung cancer was spurious.

In 1948, Doll and Austin Bradford Hill teamed up to see if they could learn anything about the causes of the cancer epidemic. Hill had been the chief statistician on a highly successful randomized controlled trial, published earlier that year, which had proved that streptomycin—one of the first antibiotics—was effective against tuberculosis. The study, a landmark in medical history, not only introduced doctors to “wonder drugs” but also cemented the reputation of randomized controlled trials, which soon became the standard for clinical research in epidemiology. Of course Hill knew that an RCT was impossible in this case, but he had learned the advantages of comparing a treatment group to a control group.

ICS had received new funding, and Paul Lipeyah was about to roll out the program to seven new schools. Kremer urged Lipeyah to test his program using what’s called a randomized controlled trial: he would monitor and collect data for fourteen local schools, implementing the program in seven of them, while letting the other seven go about business as usual. By collecting data from all fourteen schools to see which fared better, he could find out if his program actually worked. In hindsight, Kremer’s idea seems obvious. Randomized controlled trials are the gold-standard method of testing ideas in other sciences, and for decades pharmaceutical companies have used them to test new drugs.

Randomized controlled trials are the gold-standard method of testing ideas in other sciences, and for decades pharmaceutical companies have used them to test new drugs. In fact, because it’s so important not to sell people ineffective or harmful drugs, it’s illegal to market a drug that hasn’t gone through extensive randomized controlled trials. But before Kremer suggested it, the idea had never been applied to the development world. With the help of collaborators, Kremer tested the different ICS programs one by one. First, he looked at the efficacy of providing schools with additional textbooks. Classrooms would often have only one textbook for a class of thirty, so it seemed obvious that providing more textbooks would help students learn.

Robustness of evidence is very important for the simple reason that many programs don’t work, and it’s hard to distinguish the programs that don’t work from the programs that do. If we’d assessed Scared Straight by looking just at before-and-after delinquency rates for individuals who went through the program, we would have concluded it was a great program. Only after looking at randomized controlled trials could we tell that correlation did not indicate causation in this case and that Scared Straight programs were actually doing more harm than good. One of the most damning examples of low-quality evidence concerns microcredit (that is, lending small amounts of money to the very poor, a form of microfinance most famously associated with Muhammad Yunus and the Grameen Bank).

Around the time I was reading about Kravinsky I became aware of the work of Abhijit Banerjee and Esther Duflo, professors of economics at MIT, who founded the Poverty Action Lab to carry out “social experiments”—by which they meant empirical research to discover which interventions against poverty work and which do not. Without such evidence, Duflo points out, we are fighting poverty the way medieval doctors fought illness by applying leeches.3 Banerjee and Duflo pioneered the application of randomized controlled trials, the golden standard of the pharmaceutical industry, to specific aid projects. By 2010 researchers associated with the Poverty Action Lab—now known as the Abdul Latif Jameel Poverty Action Lab, or J-PAL—had carried out 240 experiments in 40 countries. Dean Karlan, once a student of Banerjee and Duflo and now himself a professor of economics at Yale, started Innovations for Poverty Action, a nonprofit organization to bridge the gap between academic research and the practical side of development.

Faye, Niehaus, Shapiro, and Wanchoo have tried to run it like the nonprofit they had wanted to give to in their graduate school days. GiveDirectly is clear and specific about what it does with money and conducts rigorous, transparent research to document the impacts of its transfers. The founders worked with independent researchers to conduct a randomized controlled trial and preannounced the study in order to tie their hands and make sure they couldn’t hide any failures. Their vision for the future is to establish cash transfers as the benchmark that donors use to evaluate whether other, more traditional approaches are worth what they cost.8 I first met Henry Spira in 1974, when he attended an adult education course on animal liberation that I taught at New York University.

In 2013 GiveWell recommended only three charities, two of which specialize in treating parasitic worm infections that cause children to develop anemia and slow their progress in school, while the third is GiveDirectly, which, as we saw in chapter 5, was founded to give cash grants directly to very poor people. These interventions have been evaluated by randomized controlled trials, the same means that pharmaceutical companies use to test new drugs. Before the intervention, a pool of potential recipients is identified and baseline measurements of their health or well-being are taken. Usually the recipients will be individuals, but in some cases they will be entire villages.

In 1990, Wyeth-Ayerst had requested that the FDA approve Premarin for the prevention of heart disease in postmenopausal women, notwithstanding the lack of evidence from randomized controlled trials documenting such a benefit. Cynthia Pearson, of the nonprofit, independent National Women’s Health Network, pointed out in an FDA hearing that the evidence supporting this claim was weak: “You couldn’t approve a drug for healthy men without a randomized clinical trial. Even aspirin [to prevent heart disease] had to have a randomized controlled trial with healthy men.” Ms. Pearson’s argument—that the standard for the gander ought to apply to the goose—prevailed. The FDA ruled that a randomized controlled trial was necessary to justify the claim that HRT decreased a woman’s risk of heart disease.

Perhaps the strongest evidence supporting routine HRT was presented in a 1997 article published in NEJM showing that “mortality among women who use postmenopausal hormones is lower than among nonusers,” again overriding continuing concerns about the link to breast cancer. HOW DID SO MANY PEOPLE GET IT SO WRONG? It helps to take a step back and look at the methods used in medical research. The two most common types of medical studies are randomized controlled trials (RCTs) and observational studies. A simple example demonstrates how these types of studies differ and illustrates the inherent strengths and weaknesses of each. Imagine that researchers want to study the impact that running a 10-kilometer road race has on women’s health over a one-year period.

But perhaps when the researchers designed the questionnaire, they weren’t smart enough to include a question that identified this belief, which could be the real reason why the runners were healthier one year after the race. Without being aware of this difference between the groups, the researchers might incorrectly attribute the runners’ better health to their having participated in the race. The other way to do this study is a randomized controlled trial, the gold standard of medical research. This study design provides a much more precise way to identify the factors that contribute to a particular outcome. Continuing with the example of the 10K race, researchers would find 200 women who agreed to participate in a study about the health effects of running such a race.

Moreover, much of what economists do is to collect and analyze data about how markets work, work that is largely done with great care and statistical expertise, and importantly, most of this research does not depend on the assumption that people optimize. Two research tools that have emerged over the past twenty-five years have greatly expanded economists’ repertoire for learning about the world. The first is the use of randomized control trial experiments, long used in other scientific fields such as medicine. The typical study investigates what happens when some people receive some “treatment” of interest. The second approach is to use either naturally occurring experiments (such as when some people are enrolled in a program and others are not) or clever econometrics techniques that manage to detect the impact of treatments even though no one deliberately designed the situation for that purpose.

We can’t do evidence-based policy without evidence. Although much of the publicity about the BIT has rightly stressed its use of behavioral insights to design changes in how government operates, an equally important innovation was the insistence that all interventions be tested using, wherever possible, the gold-standard methodology of randomized control trials (RCTs)—the method often used in medical research. In an RCT, people are assigned at random to receive different treatments (such as the wording of the letters in the tax study), including a control group that receives no treatment (in this case, the original wording). Although this approach is ideal, it is not always feasible.¶ Sometimes researchers have to make compromises in order to be able to run any sort of trial.

In this case, the removal is quite literal. Whether or not this specific implementation will ever be adopted on a large scale, remembering this example may provide someone with an inspiration for a powerful nudge in another situation. Second, the example illustrates potential pitfalls of randomized controlled trials in field settings. Such experiments are expensive, and lots of stuff can go wrong. When a lab experiment gets fouled up, which happens all too often in labs run by Humans, a relatively small amount of money paid to subjects has been lost, but the experimenter can usually try again. Furthermore, smart experimenters run a cheap pilot first to detect any bugs in the setup.

Or consider the causal link between growing up in poverty and future cancer risk: It is not as easy to change someone’s economic status as it is to tell them to take a new pill. When possible, the best strategy to determine causality is to change the exposure and observe whether the outcome changes; this is fundamentally what happens when researchers conduct randomized controlled trials. But when that isn’t feasible, we need some other tools. In 1965, British epidemiologist Sir Austin Bradford Hill listed nine criteria he considered as evidence supporting causality. Temporality was just one of them. The “Bradford Hill criteria” have come under fire over the years but still remain one of the standards by which researchers explore causal hypotheses.

How can it be failing when virtually every expert is lining up to endorse it? To answer that question we will examine one of the most important scientific innovations of the last two hundred years, and one that takes us to the heart of the closed-loop phenomenon—and how to overcome it. The randomized control trial. II Closed loops are often perpetuated by people covering up mistakes. They are also kept in place when people spin their mistakes, rather than confronting them head on. But there is a third way that closed loops are sustained over time: through skewed interpretation. That was the problem that bedeviled bloodletting, practiced by medieval doctors.

But we don’t really know. This may seem like a trivial point, but the implications are profound. Now look at another diagram, below. Here the patients have been randomly divided into two groups. Some of them get access to bloodletting while the others (called the control group) do not. This is known as a randomized control trial (RTC); in medicine it is called a clinical trial. We see from the diagram that many of the patients who receive bloodletting recover. It looks successful. The feedback is impressive. But now look at the group who did not get the treatment. Many more have recovered than in the treated group.

A rebuttal is the yes-but-what-if question that naturally arises in any but the most self-evident arguments. Consider an attempt to show that a medication is effective at treating warts. If our claim is that the medication cures warts; that our evidence is a randomized controlled trial; and our justification is that randomized controlled trials are evidence of causal relationships, then common rebuttals would be that the randomization may have been done improperly, that the sample size may have been too small, or that there may be other confounding factors attached to the treatment. It pays to be highly aware of what the rebuttals to our arguments are, because those are the things we will need to answer when we need to make a water-tight argument.

A design is a method for grouping units of analysis according to certain criteria to try to reduce uncertainty in understanding cause and effect. This is where causal influence actually begins. Techniques like within-subject designs and randomized controlled trials fall here. These methods make an effort to create defensible causal knowledge of a greater or lesser degree, depending on the number of issues stymieing causal analysis that we can eliminate. Randomized controlled trials are at the far end of this part of the causal spectrum. On the very far end of the causal spectrum are arguments for which a causal relationship is obvious, such as with closed systems (like components in a factory) or well-established physical laws.

That is, we are interested in how well a causal explanation generalizes to new situations. Intervention Designs A number of different design strategies exist for controlling for confounders. In a typical randomized controlled trial, we randomly assign the treatment to the subjects. The justification for the claim that we can infer generalizability is that, because the treatment was chosen randomly for each unit, it should be independent of potential confounders. There are numerous rebuttals for randomized controlled trials, the details of which would take up many books. The randomization may have been done improperly. The proposed treatment might not be the only difference between groups (hence double-bind experiments).

This abnormal form of hemoglobin can still carry oxygen, but its accumulation in the blood is a marker for the metabolic syndrome, the onset of Type 2 diabetes, and cardiovascular disease. I suspect HbA1c may also exert direct pathological effects, although this is not known for certain. An important systematic analysis of the data on progressive resistance exercise (that is, actual training) by Irvine and Taylor,22 encompassing 9 randomized controlled trials and 372 experimental subjects, found that strength training led to reductions in HbA1c in patients with Type 2 diabetes. Data on the beneficial effect of resistance training on insulin sensitivity and metabolic syndrome goes back decades,23 although its implications have been slow to percolate up into the consciousness of the public, or even the modern medical mind.

Qigong is part of the wellness program of ancient Chinese medicine, a practice that has been developed and refined for more than five thousand years. Much like Kriya Yoga, Qigong induces a state of concentration and relaxation by integrating the body and mind. It is supported by thousands of years of practice but also the best kind of scientific evidence—randomized, controlled trials. For example, Qigong reduces depression12 and may improve diabetes.13 In a trial of Qigong on cell aging, researchers examined people with chronic fatigue syndrome. They found that people who practiced Qigong for four months had significantly greater increases in telomerase, and reductions in fatigue, than people who were assigned to a wait list.14 A teacher showed the volunteers how to do Qigong for the first month, and then they practiced on their own at home, thirty minutes a day.

He wanted to see how this program might affect cell aging, so he studied this in men with low-risk prostate cancer. The men ate a diet high in plants and low in fat; they walked for half an hour, six days a week; they attended weekly support group sessions. They also practiced stress management on their own, with gentle yoga stretches, breathing, and meditation. In a prior randomized, controlled trial, this program was shown to slow or stop the progression of early-stage prostate cancer. At the end of the three months, the men’s telomerase had also increased. Further, those who had greater reductions in their distressing thoughts about prostate cancer had the larger increases in telomerase, suggesting that stress reduction contributed to the improvements seen.15 He followed a subgroup of these men for five years, and the ones who adhered to the program had significantly lengthened telomeres by 10 percent.

Cash transfer schemes that at present are overwhelmingly targeted at ‘the poor’ have the potential to prepare the way for basic income.2 But four factors have so far impeded the transition – a belief in ‘targeting’ (only the poor should receive the cash), ‘selectivity’ (some groups should have priority), ‘conditionality’ (recipients should be required to undertake certain actions or behave in certain ways), and ‘randomization’ (policy should only be introduced when it has been tested, or evaluated, by randomized control trials, and thus be ‘evidence-based’). This chapter briefly surveys findings from cash transfer schemes of most relevance for basic income and then considers the outcomes of genuine basic income pilots. But the fourth factor needs to be dealt with first, since a fetish with a particular method of evaluation risks distracting attention from what is most important and delaying progress in policy implementation. In randomized control trials (RCTs) of cash transfers, some people are given cash, others are not, and the results for the two groups are compared over time.

Everyone in the village, including children but excluding over-sixties already receiving a social pension, was given a very small basic income of N$100 a month (worth US$12 at the time or about a third of the poverty line), and the outcomes compared with the previous situation. The results included better nutrition, particularly among children, improved health and greater use of the local primary healthcare centre, higher school attendance, increased economic activity and enhanced women’s status.41 The methodology would not have satisfied those favouring randomized control trials that were coming into vogue at the time. No control village was chosen to allow for the effects of external factors, in the country or economy, because those directing the pilot felt it was immoral to impose demands, in the form of lengthy surveys, on people who were being denied the benefit of the basic income grants.

This encouraged villagers to plant more vegetables, buy more fertilizer and rear more livestock. These dynamic community-wide economic effects are usually overlooked in conventional evaluations, and would not be spotted if cash was given only to a random selection of individuals or households and evaluated as a randomized control trial. Another outcome, unplanned and unanticipated, was that villagers voluntarily set up a Basic Income Advisory Committee, led by the local primary school teacher and the village nurse, to advise people on how to spend or save their basic income money. The universal basic income thus induced collective action, and there was no doubt that this community activism increased the effectiveness of the basic incomes.

Similarly, to better understand our technology fixation, it’s important to recognize its larger social and historical context. As I began to doubt the hype around packaged interventions, I wanted to see if I could bypass their problems. Maybe there were other approaches to social change. So I engaged with three ideas that have growing support – randomized controlled trials, social enterprises, and happiness as a goal. These are largely unrelated efforts, but they all have great merit and are well-regarded within their specializations. Promisingly, each had a potential claim to exorcising the curse of packaged interventions. The Randomista Revolution In July 2011 I visited a school in Kotra, a little village in southern Rajasthan.

The research team was led by Esther Duflo, a brilliant MIT economist who counts among her honors a MacArthur “genius grant” as well as the John Bates Clark Medal, a good predictor of future Nobel laureates. As a pioneering member of the Abdul Lateef Jameel Poverty Action Lab (JPAL), Duflo has been a tireless advocate for the use of randomized controlled trials (RCTs) to verify the value of antipoverty programs. This is the methodology used in clinical medicine, whereby a control group establishes a baseline against which the effectiveness of a treatment can be compared. In applying the rigor of hard science to social questions, Duflo and her colleagues are revolutionaries.

If “the landlord says your rent is late,”53 the right response isn’t not to worry. It’s to move in with a relative, live on a tighter budget, get another job, upgrade your skills, apply for public assistance, or do anything else that would sow, antlike, a future in which there would be less cause to worry.54 Measure for Immeasure At first glance, randomized controlled trials, social enterprise, and happiness as an objective have little in common. The first is a research methodology, the second a type of organization, and the last a policy goal. Yet these three concepts share traits that recall the problems of technologies and packaged interventions. For one thing, they all make a fetish of measurement.

This ensures that the results will not be affected by the participants’ or clinicians’ knowledge of the treatment group. When evaluating treatment research it is important to carefully consider the design of the study. As mentioned in Chapter 8, randomized controlled trials are beneficial for two reasons: (1) we make progress in understanding what forms of interventions are effective and (2) we are able to test cause-and-effect relationships (Tremblay 2008). Randomized controlled trials are one of the most rigorous ways of determining whether a particular factor plays a causal role in the development of an outcome. For example, consider an intervention in which pregnant women are randomly assigned to a group that participates in a smoking cessation program (that is effective in reducing maternal smoking) or a control group that does not participate.

Since we cannot experimentally introduce stressors to the environment, the alternative is to manipulate the environment by providing an intervention. He states, “[E]xperimental preventive interventions can kill two birds with one stone: identify basic mechanisms leading to [aggression] and identify effective preventive interventions” (p. 2618). Randomized controlled trials, which monitor effects of the intervention on gene expression, brain functioning, and behavior, will be extremely useful in improving our understanding of how environmental factors contribute to the development of psychopathy. Conclusions A common misunderstanding is that biological factors are determined by genetics alone.

In addition, research has begun to demonstrate the biological changes that can result from psychosocial interventions, suggesting that biological factors can be targeted through traditional forms of therapy. Thus, ultimate solutions to the problem of psychopathy could be both natural and, in some cases, surprisingly simple. The gold standard for prevention and treatment studies is the randomized controlled trial, in which participants are randomly allocated to treatment or control groups and the groups are treated identically except for the experimental treatment. Less controlled study designs may be able to detect associations between an intervention and an outcome, but they cannot rule out the possibility that the association may have been caused by a third factor.

Sometimes these are terrific, but everyone has them, including your competitors, and there are often methodological issues in their collection. It is worth considering whether there are options for crowd sourcing alternative data, whether prediction markets cover your topic or could be induced to, or whether your interest area is amenable to some form of A|B testing or randomized controlled trials. Custom data collection costs have come down substantially and new data sets can yield insights very different from the obvious mainstream analyses. Tools such as Survey Monkey are simple to use and can bring customer, competitor, and supplier perspectives that may be especially insightful.

As in most problem solving you need to gather some facts. In Rob's case, he read a Finnish study in The New England Journal of Medicine that indicated that when there is low discomfort and age‐degenerative meniscal tear, there is no significant improvement from APM compared to physical therapy. The research method involved a particular kind of randomized control trial termed a sham control, where participants weren't aware of whether they had the procedure or not. The conclusions of the 12‐month follow‐up were that the outcomes for the APM surgery were no better than for the sham APM surgery, notwithstanding that “both groups had significant improvement in primary outcomes.”15 Rob also wanted to assess whether he should wait for a new technology solution to develop, such as stem‐cell treatment or a printable hydrogel meniscus.

Experiments can be useful for evaluating different types of interventions. For example, a randomized‐controlled experiment can help you test whether a specific new program offering individuals incentives to walk five miles per day reduces obesity better than an existing program, controlling for all other factors. Randomized controlled trials (RCTs) require you to recruit a pool of participants, and randomly allocate participants into two or more treatment groups and a control group. In this case, the treatment is the new exercise incentive program. They work particularly well when you want evidence that a specific intervention is the likely cause of a change in outcome.

Does going to college equip you with skills that allow you to earn a good living? Or do only smart, disciplined, or privileged people, who can translate their natural assets into financial ones, make it through university? There is an impeccable way to cut these knots: the randomized experiment, often called a randomized controlled trial or RCT. Take a large sample from the population of interest, randomly divide them into two groups, apply the putative cause to one group and withhold it from the other, and see if the first group changes while the second does not. A randomized experiment is the closest we can come to creating the counterfactual world that is the acid test for causation.

If you have it, you don’t need anything else; if you don’t have it, it doesn’t matter what else you have.”25 It isn’t quite true of charm, and it isn’t quite true of random assignment either, but it is still with me decades later, and I like it better than the cliché that randomized trials are the “gold standard” for showing causation. The wisdom of randomized controlled trials is seeping into policy, economics, and education. Increasingly, “randomistas” are urging policymakers to test their nostrums in one set of randomly selected villages, classes, or neighborhoods, and compare the results against a control group which is put on a waitlist or given some meaningless make-work program.26 The knowledge gained is likely to outperform traditional ways of evaluating policies, like dogma, folklore, charisma, conventional wisdom, and HiPPO (highest-paid person’s opinion).

As we saw in chapter 3, inconsistency is fatal to reasoning: a set of beliefs that includes a contradiction can be deployed to deduce anything and is perfectly useless. Wary as I must be of inferring causation from correlation, and of singling out just one cause in a crisscrossing historical mesh, I cannot claim that good arguments are the cause of moral progress. We cannot do a randomized controlled trial on history, with half of a sample of societies exposed to a compelling moral treatise and the other half given a placebo filled with high-minded mumbo jumbo. Nor do we have a large enough dataset of moral triumphs to extract a causal conclusion from the network of correlations. (The closest I can think of are cross-national studies showing that education and access to information in one era, which are indicators of a readiness to exchange ideas, predict democracy and liberal values in a later one, holding socioeconomic confounds constant.)18 For now I can only give examples of precocious arguments that historians tell us were influential in their day and that remain unimpeachable in ours

He visited Atkins’s office in New York City in the late 1990s and was impressed by his success in helping patients to lose weight and improve health. But he decided that the files weren’t good enough. “I need science,” he told Atkins. Westman knew that the only way to make sense of various anecdotal accounts was to do randomized controlled trials, the gold standard of medical evidence. So he, along with a few colleagues around the country, started conducting those trials. This new group of researchers entering the field were young and relatively ignorant about the professional sandpit into which they’d be sinking. Gary Foster, for instance, a professor of psychology at Temple University who took part in a landmark trial comparing different diets in 2003, says he had no idea that including the Atkins regime in his study would be so contentious.

Elderly hunter-gatherers and others who remain active throughout their life span testify to the welcome news that using muscles retards muscle loss as we age. Indeed, aging does not put an end to muscles’ capacity to respond to resistance exercise; instead, modest levels of resistance exercise slow and sometimes reverse sarcopenia regardless of age thanks to the mechanisms we have already reviewed. Dozens of randomized control trials have found that prescribing moderate, non-strenuous levels of weight training helps older individuals increase their muscle mass and strength and thus improve their ability to function normally and stay active without requiring assistance.54 One study even demonstrated marked improvements in strength among eighty-seven- to ninety-six-year-old men and women following eight weeks of resistance training.55 Critically, by halting and reversing sarcopenia, these interventions decrease injury risk and enhance quality of life for the elderly.

Good to Go: What the Athlete in All of Us Can Learn From the Strange Science of Recovery by Christie Aschwanden

“There’s a lot of company-run tests where they say, oh yeah, there’s a little bit of evidence with this,” she says, but she wanted to see some stronger proof and studies that applied to runners. “Some of the studies will have people do a one-rep max on some weight exercise, but I’m like, what does that mean for running?” Randomized, controlled trials are the gold standard in medicine, and Badowski Wu and some colleagues, including Martin Hoffman, the Sacramento VA Medical Center researcher who wrote hydration guidelines, figured they could apply that approach to recovery modalities too. So they designed and conducted a randomized, controlled trial of massage and pneumatic compression on participants in the 2015 Western States Endurance Run.10 (The race has a unique program to fund and encourage scientific research on the event and its participants.)

Researchers running drug studies in the United States are now required to register their plans and protocols in advance at ClinicalTrials.gov and to report and share all their results, not just the positive findings.8 These requirements were implemented to ensure that regulators and the public get the full picture, and not just results cherry-picked to make a product look good. The system doesn’t work perfectly and it can’t cull every false positive finding, but a 2015 analysis showed that after the launch of ClinicalTrials.gov in 2000, the proportion of trials that found a positive benefit plummeted.9 Prior to 2000, for example, 57 percent of large randomized, controlled trials sponsored by the National Heart, Lung, and Blood Institute showed that the treatment worked. After 2000, that number dropped to 8 percent. But no such rules or conventions apply to nutritional studies, which means that supplement companies and the researchers they fund can fish around for positive results until they find something that paints the product in a positive light.

I waited for scientists from a wider range of fields, including neuroscience and behavioral psychology, to weigh in with their theories on how a gameful mindset can help. Most important, I waited until I could team up with doctors and psychology researchers myself to test the SuperBetter method in rigorous studies—and I have, with a randomized, controlled trial with the University of Pennsylvania and with a clinical trial with the Ohio State University Wexner Medical Center and Cincinnati Children’s Hospital. (You’ll read about that research in “About the Science,” at the end of this book.) Not a day has gone by in these five years that I haven’t received an email or Facebook message from someone telling me how much SuperBetter has inspired them or helped their family.

The scientists at ECU attached monitoring devices to game players in order to track two specific measures of emotional and physical resilience: electroencephalographic (EEG) changes in alpha brain waves, which can indicate whether you’re distressed, depressed, or in an overall good mood; and heart rate variability, which reflects how quickly your body can recover from emotional or physical stress. The group’s first randomized, controlled trial found that a twenty-minute session of casual game play decreased left frontal alpha brain waves, which typically indicates improved mood. Indeed, on a survey, the players with decreased alpha brain waves reported feeling in a better mood. They had significantly less anger, depression, and tension and more energy.

Poor Economics: A Radical Rethinking of the Way to Fight Global Poverty by Abhijit Banerjee, Esther Duflo

In doing so, we were following a long tradition of development economists who have emphasized the importance of collecting the right data to be able to say anything useful about the world. However, we had two advantages over the previous generations: First, there are now high-quality data from a number of poor countries that were not available before. Second, we have a new, powerful tool: randomized control trials (RCTs), which give researchers, working with a local partner, a chance to implement large-scale experiments designed to test their theories. In an RCT, as in the studies on bed nets, individuals or communities are randomly assigned to different “treatments”—different programs or different versions of the same program.

To get them started, BRAC designed a program in which they would be given an asset (a pair of cows, a few goats, a sewing machine, and so on), a small financial allowance for a few months (to serve as working capital and to ensure they would not be tempted to liquidate the asset), and a lot of hand-holding: regular meetings, literacy classes, encouragement to save a little bit every week. Variants of this program are currently being evaluated in six countries, using randomized control trials (RCTs). We were involved in one of these studies, in partnership with Bandhan, an MFI in West Bengal. We visited households before the program was started and heard, from each of the families that were selected for the program, stories of crisis and desperation: A husband was a drunkard and regularly beat his wife; another died in an accident, leaving a young family behind; a widow was abandoned by her children; and so forth.

Inquiries suggested that a lot of the money most likely ended up in the pockets of district officials. It is easy to get depressed by such findings (which have been corroborated by similar studies in several other countries). We are often asked why we do what we do: “Why bother?” These are the “small” questions. William Easterly, for one, criticized randomized control trials (RCTs) on his blog in these terms: “RCTs are infeasible for many of the big questions in development, like the economy-wide effects of good institutions or good macroeconomic policies.” Then, he concluded that “embracing RCTs has led development researchers to lower their ambitions.”3 This statement was a good reflection of an institutionalist view that has strong currency in development economics today.

It makes far more sense to say that people display bounded rationality than to accuse them of “irrationality,” and for many purposes, bounded rationality is just fine, producing outcomes that are equal to or perhaps even better than what would emerge from efforts to optimize by assessing all costs and benefits. With respect to errors, more is being learned every day. Some behavioral findings remain highly preliminary and need further testing. There is much that we do not know. Randomized controlled trials, the gold standard for empirical research, must be used far more to obtain a better understanding of how the relevant findings operate in the world.22 Even at this stage, however, the underlying findings have been widely noticed, and behavioral economics, cognitive and social psychology, and related fields have had a significant effect on policies in several nations, including the United States and the United Kingdom.

What if the program could slow down or interrupt a young man’s rage, so that a dispute over a basketball game wouldn’t end in a murder? In May 2009, Youth Guidance won the Crime Lab’s “innovation challenge” and received funding to scale up its work to 18 schools. One condition of the funding was that the work would be studied via a randomized control trial (RCT).II The key question that would be studied was: Would BAM reduce arrests—especially for violent acts? Youth Guidance was taking a risk in agreeing to this. The probability, in general, of finding a large, significant result in a social-science RCT is pretty low—which is not hard to understand when you realize that interventions might act upon only one or two variables within the overwhelmingly complex and interconnected system that is the human life.

Beyond the parenting instruction, a crucial part of the work is simply to be a caring human being who’s there to support the mother. To show her how to take care of herself so that she can care for her child. To help her navigate the complexities of working while raising a child. To listen when the pressures of life seem overwhelming. Three major randomized controlled trials of NFP have been conducted in the United States: in Elmira, New York; Memphis, Tennessee; and Denver, Colorado. The studies have shown that the program consistently improves maternal health, child safety, and well-being. Among the specific impacts were reductions in smoking during pregnancy, preterm births, infant mortality, child abuse and maltreatment, and criminal offenses by the mother, Food Stamp payments, and closely spaced pregnancies (second births within 18 months of the first).

A group in South Carolina designed a “pay for success” model that could fund a wide expansion of NFP’s work. Here’s how they set it up: In 2016, NFP received a $30 million infusion of cash to expand its work in the state, and the results of its efforts will be assessed over six years via a randomized control trial. If the work is successful, according to several measures agreed upon in advance, then the state government would be positioned to fund the work permanently. The magic of the arrangement is that the state government doesn’t take a big financial risk upfront, because the trial stage was mostly funded from outside.

The Death of Cancer: After Fifty Years on the Front Lines of Medicine, a Pioneering Oncologist Reveals Why the War on Cancer Is Winnable--And How We Can Get There by Vincent T. Devita, Jr., M. D., Elizabeth Devita-Raeburn

Also bad news: Under the Kefauver-Harris Amendment, or “Drug Efficacy Amendment,” of 1962, proof of efficacy was to be determined in “adequate and well controlled trials.” The act mentions only the use of historical controls—that is, data from previous studies. The amendment did not require new randomized controlled trials, as people often think. The requirement for these new trials—often an unnecessary impediment in early drug trials—was added by the FDA in its interpretation of the regulations: another FDA grab. Today we seem to be mindlessly wedded to the use of randomized controlled trials. They have their place. But randomized clinical trials can be unethical. Doctors sometimes have strong beliefs about the effectiveness of treatments being compared in a randomized trial—often with good reason.

Fearing the FDA would approve this practice, he testified before the ODAC to protest his agency’s own positions. (He told me in a recent phone call that had he testified as an FDA employee, he would have had to support its position.) Young wanted data on cisplatin tested alone in testicular cancer and in a randomized controlled trial against other treatments, as required in the Code of Federal Regulations, his bible. Our data in childhood leukemia and Hodgkin’s disease had already shown the need for drugs to be used in combination to cure cancers. What Young wanted to do—treating patients with a single agent, cisplatin—would have meant jeopardizing the lives of patients.

It had been noted, anecdotally, that some patients who present with kidney cancer that has already spread to their lungs go into a remission when you remove the primary tumor—the involved kidney. This was once considered a rash thing to do. Why subject patients to expensive major surgery when they already had widespread cancer? There was no proof it worked, just the observation of a few overzealous (or very astute) doctors. In 2001, we did get some evidence in the form of two randomized controlled trials.10 Half of patients who had a new diagnosis of metastatic kidney cancer were treated with interferon, a mediocre treatment for kidney cancer, while the other half were treated with removal of the diseased kidney plus interferon. In both studies, the survival of patients who had a kidney removed was significantly longer.11 What was the primary tumor doing to influence the growth of metastases?

She also looked at the negative-income-tax experiments conducted by the United States government in the late 1960s and 1970s, as the administrations of Lyndon Johnson and Richard Nixon sought more and better ways to tackle the problems of deep poverty, a lack of engagement with the labor force, and the dissolution of the family. (Negative income taxes, or NIT, boost a household’s income rather than reducing it.) The government conducted NIT pilots in seven states during the Brady Bunch years, the first randomized control trials in the United States. (In a curious historical wrinkle, Donald Rumsfeld and Dick Cheney were involved.) In most cases, there was some reduction in work effort. In a large experiment conducted in Seattle and Denver, for instance, the employment rate fell by a considerable four percentage points.

Wouldn’t a safety net fast become a hammock, as Republicans are so fond of claiming? As we saw, that argument has been disproven conclusively in higher-income countries. Much the same turns out to be true in developing countries and among the world’s very poor. A prominent group of economists recently looked at randomized control trials of government cash-transfer programs from Honduras, Indonesia, Morocco, Mexico, Nicaragua, and the Philippines. They found that receiving cash had no effect on the number of hours worked or the propensity to work, for both men and women. Indeed, the cash-transfer programs seemed to boost the amount that men worked, in some cases.

The only thing preventing us from getting there, and to $300 million the next year, is capital.” * * * Before launching its UBI pilot, GiveDirectly provided large lump-sum payments to the poorest people in a given village rather than distributing small payments for a long time to everybody. A randomized control trial, the gold standard for research in academic economics as well as a number of other disciplines, demonstrated that these cash transfers had powerful effects. After receiving payments of $404 or $1,525, household assets increased by 58 percent. Business and agriculture income increased by 38 percent, with an implied annual rate of return of 28 percent.

Even so, he managed to imply that it had been foolish. And yet, while it’s true the chicken was a creature of habit, expecting to be fed that fateful day simply because it had always been fed before, was that really so bad? We could make a case for the chicken’s good judgement. Philosopher Nancy Cartwright jokes that a randomized controlled trial on the relationship between chickens turning up in the farmyard and being fed (run during the summer) would have confirmed the chicken’s belief. In any case, what’s wrong with expecting a little regularity in life? It doesn’t seem a lot to ask. In fact, it’s hard to see how we would cope without it.

In short, we’re a lot like the chicken, as Russell says, which would be fine, except that the chicken dies, brutally. What that illustrates is how deep-rooted and necessary it usually is to think that our knowledge of cause and effect is dependable enough to travel; but also how vulnerable that expectation can be to factors that we do not know we do not know. Nancy Cartwright’s semi-joke that a randomized controlled trial would have backed up the chicken’s belief is to point out how much contextual detail you would need to know about the behaviour and social structure of farmers, farms and Christmas in order to understand what it is you are looking at when you watch the chicken being fed every day. All this, for the chicken, is a vital hidden half.

It appears to have similar efficacy for treating depression (at least mild to moderate types) as the labor-intensive face-to-face visits with a mental health professional. There are plenty of CBT mobile apps including Lantern, Joyable, MoodGYM, and Ginger.io. A meta-analysis of eighteen randomized control trials of more than 3,400 patients using twenty-two smartphone apps for treating depression showed significant improvement, and those apps based on CBT were particularly effective.46 All those apps studied involve interactions with human beings, but not all apps rely on human interaction. Wysa, a penguin chatbot, has attracted 50,000 users who engaged in a million conversations in just three months; more than five hundred wrote in comments to say how much it helped with their mental health problem.47 Woebot uses an instant messenger app to conduct sessions with users.

It uses deep learning to peg the relationship between a person’s heart rate and physical activity, to prompt the user to record an electrocardiogram if his or her heart goes off track, and to look for evidence of atrial fibrillation. AliveCor’s watch exemplifies the type of assistance developed to date. I won’t try to review every possible example here, but I will cover enough to give you a flavor of where we stand in this nascent phase of the medical AI coach. There’s an important common thread here: no randomized, controlled trials have been shown to improve outcomes. Instead, the products have largely relied on small retrospective or observational studies. It’s a major hole in their stories that needs to get filled in. Nevertheless, the developments are worth examining. Diabetes has been a popular target. Onduo, a company formed by Verily and Sanofi, is perhaps furthest along because it combines smartphone AI recognition of food and meals, continuous glucose sensor data, and physical activity (or what is really just steps taken) to provide coaching via texts.

Career success is independent of whether or not projects have been successful, so there is no pressure for convincing evaluation. These arguments have led to a movement toward more careful evaluation, often with an emphasis on randomized controlled trials as the best way of finding out whether a given project worked and, beyond that, of finding out “what works” in general. (In randomized controlled trials, some “units”—people or schools or villages—get treated, and some—the controls—do not, with units assigned to one of the two groups at random.) According to this view, aid has been much less effective than it would have been had past projects been seriously evaluated.

If the World Bank had subjected all of its projects to rigorous evaluation, the argument goes, we would by now know what works and what does not work, and global poverty would have vanished long ago. Those who favor randomized controlled trials—the randomistas—tend to be very skeptical of typical self-evaluations by NGOs, and they have worked with cooperative NGOs to help strengthen their evaluation procedures. They have also persuaded the World Bank to use randomized controlled trials in some of its work. Finding out whether a given project was or was not successful is important in itself but unlikely to reveal anything very useful about what works or does not work in general.

According to the Mayo Clinic, “Diuretics … help rid your body of salt (sodium) and water. They work by making your kidneys put more sodium into your urine. The sodium, in turn, takes water with it from your blood. That decreases the amount of fluid flowing through your blood vessels, which reduces pressure on the walls of your arteries.”7 An important randomized controlled trial from the U.S. Veterans Administration was published in 1970,8 and thereafter practice changed quickly in the United States. One of the characteristics of the U.S. health-care system is that innovations tend to be introduced very quickly—not only the good ones like antihypertensives, but also many that are of dubious value.

But I was impressed by the fact that the article was in The Lancet, one of the world’s three most influential medical journals, along with The New England Journal of Medicine and The Journal of the American Medical Association. The other articles I had found were all in smaller, specialized journals. Moreover, the topiramate study was larger and longer than the baclofen studies in the other articles, and it was a randomized controlled trial, the gold standard of modern medicine. Last but not least, it was brand-new. “This must be the cutting edge,” I thought. It seemed like my best hope yet for achieving complete abstinence from alcohol. I went to the medical library at the Pompidou Centre to read the entire article and make a photocopy.

Gordon Allport, a professor of psychology at Harvard, formulated what he called the contact hypothesis in 1954.81 This is the idea that under appropriate conditions, interpersonal contact is one of the most effective ways to reduce prejudice. By spending time with others, we learn to understand and appreciate them, and as a result of this new appreciation and understanding, prejudice should diminish. The contact hypothesis has been intensively studied. A recent review identifies twenty-seven randomized controlled trials (RCTs) investigating Allport’s idea. Overall, these studies find that contact reduces prejudice, although the review calls attention to the importance of the nature of the contact.82 If this is right, schools and universities are obviously key. They bring together young people from different backgrounds in a single location, at an age when everyone is much more plastic.

But obviously they are different, and treating them the same may lead us to vastly underestimate the value of the internet. Faced with the possibility that we could be either massively overvaluing the internet or the other way around, scholars looked for other ways to measure its value to consumers. In particular, there were several randomized control trials of what happened when the experimenter (with the permission of the participant) blocked access to Facebook (or social media more generally) for a random group of individuals for some relatively short period of time. The biggest of these experiments, which involved more than two thousand participants paid to deactivate Facebook for a month, found that those who stopped using Facebook were happier across a range of self-reported measures of happiness and well-being and, interestingly, no more bored (perhaps less).

A rule of thumb in the social investing world is that 10 percent of the ventures work out (the rest fold) and only 1 percent reach significant scale. The issue is more that it is difficult to identify those supposedly life-changing new products and services, and efforts to do so often meet a frustrating lack of interest from the people whose lives are supposed to be changed. Electricity is a case in point. In a recent randomized controlled trial in Kenya, researchers partnered with Kenya Rural Electrification Authority to offer electricity connection at different prices in different communities. The demand fell very sharply as price rose, and villagers were not willing to pay anywhere near what would have been sufficient to cover the cost of connecting to the grid (not to mention building the grid).86 The frugal engineering world is littered with many similar disasters, from the $100 laptop to educate the world (which actually costs $200 and has been shown to have no impact on what children actually learn),87 to cleaner cookstoves that nobody wanted,88 to various water-filter technologies89 and innovative latrines.90 A lot of the problem seems to be that these innovations take place in a void, insufficiently connected to the lives they wish to change.

When the disappointing results were published in 1982, The Wall Street Journal headline said it all: “Heart Attacks, a Test Collapses.” *In September 2009, the World Health Organization’s Food and Agricultural Organization published a reassessment of the data on dietary fat and heart disease. “The available evidence from [observational studies] and randomized controlled trials,” the report stated, “is unsatisfactory and unreliable to make judgment about and substantiate the effects of dietary fat on risk of CHD [coronary heart disease].” *This was the trial of calorie-restricted diets carried out by researchers from Harvard and the Pennington Biomedical Research Center by Frank Sacks and his colleagues that I discussed in chapter 2.

Barack Obama substantially expanded the use of RCTs for federal programs, along with other evidence-based measures such as “tiered evidence” grant programs, Pay-for-Success initiatives, and the establishment of the White House Social and Behavioral Sciences Team.

It is easiest to understand how these approaches help us get at causality by starting with randomized experiments—the gold standard for identifying causal effects in one place and time—and then covering methods that we turn to when randomized experiments are impossible. During the twentieth century the natural sciences worked out an efficient way to draw a line from cause to effect, the randomized controlled trial (RCT). The best way to test a new drug is to draw a large group of test subjects, randomly assign them to a treatment group, who receive it, and a control group, who do not, and measure the difference in results between the two groups. Randomization provides, on average, the real-world counterfactual we mentioned earlier.

It also has a maternal health component: to qualify for the grants, expectant mothers must get regular checkups, attend family development education sessions, and use health professionals at childbirth. To allow World Bank researchers to rigorously evaluate the effects of the program, the government rolled it out by randomized controlled trial in part of the country. Of a sample of 130 villages, a treatment group of 65 received the program in 2009, while a control group of equal size was held back, not receiving the program until 2011. The World Bank study provided evidence that this CCT made successful progress toward its specific development targets.67 Day care enrollment rose 11 percentage points (to 76 percent in treatment villages as compared to 65 percent in control villages), school attendance rose to 95 percent relative to 91 percent (among controls), antenatal care was received by 64 percent of new mothers versus 54 percent, and so on.

First, Rose’s logic does not differentiate between hypotheses. It would invariably be invoked to explain why studies failed to confirm Keys’s fat hypothesis, and would be considered extraneous when similar studies failed to generate evidence supporting competing hypotheses. It is precisely to avoid such subjective biases that randomized controlled trials are necessary to determine which hypotheses are most likely true. Second, as Rose observed, all public-health interventions come with potential risks, as well as benefits—unintended or unimagined side effects. Small or negligible risks to an individual will also add up and can lead to unacceptable harm to the population at large.

Epidemiological studies have not, however, generally distinguished between degrees of refining or processing of starches, and there are, as yet, no reliable epidemiological data specifically on the effects of refining on cancer risk. Cleave’s saccharine-disease hypothesis may be intuitively appealing, but it is effectively impossible to test without a randomized controlled trial. If Cleave was right, then epidemiologists comparing populations or individuals with and without chronic disease have to take into account not just sugar consumption but flour, and whether that flour is white or whole-grain, and whether rice is polished or unpolished, white or brown, and even how much beer is consumed compared with, say, red wine or hard liquor.

The pattern is precisely what would be expected of a hypothesis that simply isn’t true: the larger and more rigorous the trials set up to test it, the more consistently negative the evidence. Between 1994 and 2000, two observational studies—of forty-seven thousand male health professionals and the eighty-nine thousand women of the Nurses Health Study, both run out of the Harvard School of Public Health—and a half-dozen randomized control trials concluded that fiber consumption is unrelated to the risk of colon cancer, as is, apparently, the consumption of fruits and vegetables. The results of the forty-nine-thousand-women Dietary Modification Trial of the Women’s Health Initiative, published in 2006, confirmed that increasing the fiber in the diet (by eating more whole grains, fruits, and vegetables) had no beneficial effect on colon cancer, nor did it prevent heart disease or breast cancer or induce weight loss.

Practical Manual of Thyroid and Parathyroid Disease by Asit Arora, Neil Tolley, R. Michael Tuttle

Drosophila, epigenetics, longitudinal study, meta-analysis, mouse model, phenotype, randomized controlled trial, selection bias

Where appropriate within the text, references have been classified into the definition of types of evidence based on Agency for Health Care Policy and Research (1992). MULTIPLE CHOICE QUESTIONS Level Type of evidence Ia Evidence obtained from meta-analysis of randomized controlled trials Evidence obtained from at least one randomized controlled trial Evidence obtained from at least one well-designed controlled study without randomization Evidence obtained from at least on other type of well-designed quasi-experimental study Evidence obtained from well designed nonexperimental descriptive studies Evidence obtained from expert committee reports or opinions and/or clinical experience of respected authorities Ib IIa IIb III IV REFERENCES 1.

Key points and multiple choice questions are also included which reinforce important points and ensures the reader re-address their understanding of the disease. The book as a whole is easy to read, with highlighted case studies included where appropriate that are informative and educational. As there are no randomized controlled trials for this pathology, most conclusions are based on large non-randomized retrospective data analyses and the personal philosophy of the individual treating physician. Large databases, such as the SEER database and the National Cancer Database (NCDB), are quite helpful in correlating one’s personal philosophy to the ‘best practices’ shown in the large data that is available.

Although their size is not a completely reliable indicator of biological behaviour, nodules measuring 5 mm or less do exhibit higher rates of false-positive ultrasound (US) findings coupled with lower rates of adequate fine needle aspiration (FNA) results.12,13 Thus, imaging and fine needle aspiration cytology (FNAC) can sometimes confound the appropriate management of a thyroid nodule. Thyroid imaging 37 The increased incidence of PTC is not associated with a rise in disease-specific mortality which may, in part, reflect our increased use of thyroid imaging in recent times.14 In the absence of randomized controlled trials, it is difficult to reconcile the relatively low mortality rates from PTC with the apparently high risk features of incidentalomas shown in recent studies. FNA of all thyroid nodules certainly has enormous resource implications. The diagnostic accuracy of FNAC for thyroid malignancy is around 95% with an inadequacy rate of 10%, so if all cytologically suspicious or inadequate nodules were excised, a substantial number of patients would undergo unnecessary thyroid surgery.15 US is the best primary imaging modality for the assessment of thyroid nodules.

Ultra-Processed People: The Science Behind Food That Isn't Food by Chris van Tulleken

It had a modest, rather specific title: ‘A new classification of foods based on the extent and purpose of their processing’. The lead author was Carlos Monteiro, a professor of nutrition in São Paulo. The second paper sounded even less enticing. It was a dietary experiment about weight gain, perhaps promoting another fad: ‘Ultra-processed diets cause excess calorie intake and weight gain: an inpatient randomized controlled trial of ad libitum food intake’ (lead author: Kevin Hall). In the first paper, Monteiro advanced a theory; in the second, Hall described an experiment that tested that theory and, at least at first glance, seemed to confirm it. Here’s the theory: the main reason for the rapid increase in overweight and obesity throughout the world, especially since the 1980s, is the correspondingly rapid increase in production and consumption of ultra-processed food and drink products.

In 2008 and 2011, both the New York Times and ABC News reported on David Allison’s funding by Coca-Cola, Kraft, PepsiCo, McDonald’s and the American Beverage Association.5, 6 This funding may have no influence on what he publishes, but a recent publication of his ‘French-fried potatoes consumption and energy balance: a randomized controlled trial’ is an example of how industry-funded science frequently makes discoveries that align with the interests of the funder. The study was supported by a grant from the Alliance for Potato Research and Education (APRE). This is from the conclusion: ‘Results do not support a causal relationship between increased French-fried potato consumption and the negative health outcomes studied

These opinions were not baseless, but they proved to be wrong. Much as we wish it were otherwise, the two of us have made our share of mistaken claims and prognostications. Individual scientists don’t know everything off the bat, which is why we have scientific inquiry. We have experiments and randomized controlled trials, not just for vaccines but also to evaluate the impact of putting body cameras on police. These are the tools of effective government in the twenty-first century. We live on a complex planet and our cities are complicated organisms. We must embrace a constant need to learn. The Plan of the Book This book is divided into ten chapters, eight of which lie between the introduction and the conclusion and carry the book’s main arc.

But police commissioner William Evans and the union both had the humility to learn. They compromised on a pilot program with just one hundred cameras randomly allocated among officers. When “complaints brought against officers were cleared by videos,” the union started seeing the upsides of transparency. Moreover, a randomized control trial found that body cameras “generate small but meaningful benefits to the civility of police-citizen civilian encounters.” The union accepted the cameras. Should We Defund the Police? Defunding the police may seem like a natural response to the lawless behavior displayed by Derek Chauvin.

The solution lay in statistics: Randomly assigning people to one group or the other would mean whatever differences there are among them should balance out if enough people participated in the experiment. Then we can confidently conclude that the treatment caused any differences in observed outcomes. It isn’t perfect. There is no perfection in our messy world. But it beats wise men stroking their chins. This seems stunningly obvious today. Randomized controlled trials are now routine. Yet it was revolutionary because medicine had never before been scientific. True, it had occasionally reaped the fruits of science like the germ theory of disease and the X-ray. And it dressed up as a science. There were educated men with impressive titles who conducted case studies and reported results in Latin-laden lectures at august universities.

The rate of the development of science is not the rate at which you make observations alone but, much more important, the rate at which you create new things to test.11 It was the absence of doubt—and scientific rigor—that made medicine unscientific and caused it to stagnate for so long. Putting Medicine to the Test Unfortunately, this story doesn’t end with physicians suddenly slapping themselves on their collective forehead and putting their beliefs to experimental tests. The idea of randomized controlled trials was painfully slow to catch on and it was only after World War II that the first serious trials were attempted. They delivered excellent results. But still the physicians and scientists who promoted the modernization of medicine routinely found that the medical establishment wasn’t interested, or was even hostile to their efforts.

If crime went up, that might show the policy was useless or even harmful, or it might mean crime would have risen even more but for the beneficial effects of the policy. Naturally, politicians would claim otherwise. Those in power would say it worked; their opponents would say it failed. But nobody would really know. The politicians would be blind men arguing over the colors of the rainbow. If the government had subjected its policy “to a randomized controlled trial then we might, by now, have known its true worth and be some way ahead in our thinking,” Cochrane observed. But it hadn’t. It had just assumed that its policy would work as expected. This was the same toxic brew of ignorance and confidence that had kept medicine in the dark ages for millennia.

They are anxious because they’re overbreathing, overbreathing because they’re anxious. Feinstein found some inspiring recent studies by Alicia Meuret, the Southern Methodist University psychologist who helped her patients blunt asthma attacks by slowing their breathing to increase their carbon dioxide. This technique worked for panic attacks, too. In a randomized controlled trial, she and a group of researchers gave 20 panic sufferers capnometers, which recorded the amount of carbon dioxide in their breath throughout the day. Meuret crunched the data and found that panic, like asthma, is usually preceded by an increase in breathing volume and rate and a decrease in carbon dioxide.

One executive told us, with obvious pride, that the company had bought newspaper inserts every single Sunday for the past twenty years in 250 markets across the United States. So how could they tell whether these ads were effective? They couldn’t. With no variation whatsoever, it was impossible to know. What if, we said, the company ran an experiment to find out? In science, the randomized control trial has been the gold standard of learning for hundreds of years—but why should scientists have all the fun? We described an experiment the company might run. They could select 40 major markets across the country and randomly divide them into two groups. In the first group, the company would keep buying newspaper ads every Sunday.

Think about it this way: if parents face thousands of decisions and the parents who make far better decisions only have kids who turn out some 26 percent more accomplished, each of the thousands of decisions, by itself, can’t make a large difference. Indeed, the best studies—many of them discussed in important books by Emily Oster—have generally failed to find much effect from even the most-debated parenting techniques. Some examples: The only randomized controlled trial on breastfeeding found that it had no significant long-term effect on a variety of child outcomes. A careful study of television use found that exposure to TV had no long-term effects on child test scores. A careful randomized trial suggests that teaching kids cognitively demanding games, such as chess, doesn’t make them smarter in the long term.

Comparisons made at 1–2-year and 3–4-year follow-ups with 12 control subjects who did not have food allergy and 5 subjects with food allergy who were noncompliant with their diet showed that the 17 food-allergic subjects with appropriate dietary restriction demonstrated highly significant improvement in their AD compared with the control groups. The amount of time for resolution of their food hypersensitivity was also reduced. Lever et al. [42] performed a randomized, controlled trial of an egg exclusion diet in 55 children who presented to a dermatology clinic with AD and possible egg sensitivity identified by radioallergosorbent (RAST) testing before randomization. True egg sensitivity was confirmed by DBPCFC after the trial. The 55 children were randomized either to a 4-week regimen in which mothers received general advice on the care of AD and additional specific advice from a dietician about an egg elimination diet (diet group), or to a control group in which only general advice was provided.

That is like measuring the number of widgets a factory produces in an hour, but not how many of them are sold. The result is that money—a lot of money—is being pumped into programs that are not actually delivering decent results. Between 1990 and 2010, ten federal government social programs in the United States were evaluated using randomized control trials (RCTs), a method of randomly assigning people between one group whose members are receiving certain services and another group whose members are not. Measuring the difference in outcomes between the two tells you how useful a specific program is. Nine of the ten federal programs were found to have weak or no positive effects: they were a waste of taxpayers’ money.4 Some initiatives actually end up doing harm.

Instructors might answer questions by email, phone, or videoconference, supplemented by periodic meetings, class trips, and “live,” in-the-classroom exams. It’s often for less than half the price of a traditional K–12 schooling experience. The world still awaits systematic, rigorous (randomized control trial) studies of all of these methods of learning, and it is too early to say what is working and what is not. Nonetheless, we do know two things for sure. First, very often the online methods are much cheaper and also more flexible than the previous alternatives. Second, some learners—quite possibly a minority—love the online methods.

We still haven’t dispensed with models, because there are a few models we believe in pretty strongly, such as that when price goes up, people usually buy less of that good or service, all other things being held equal. But those are old theories and the real action and value-add comes from the data and its handling, including data from field experiments, laboratory experiments, and from randomized control trials. The underlying models just aren’t getting that much better, and when the underlying models are more complicated, they very often are not more persuasive to the typical research economist. I would sum up the blend as follows: (a) much better data, (b) higher standards for empirical tests, and (c) lots of growth in complex theory but not matched by a corresponding growth in impact.

The basic question was a pretty simple one: whether the group with access to the microcredit did better. It turned out they were more likely to have started their own businesses and thus a classic paper was born. Most people see this as the most important study of microcredit, in addition to another large-scale randomized control trial from Dean Karlan at Yale University. It’s a long way from grabbing a publicly available database from a government agency, without much worrying about the quality or meaning of the numbers, and running some regressions. Setting up the entire field experiment is also a uniquely human contribution and it does not approximate any task that is replicable with smart machines.

Two-thirds of participants remained abstinent after six months, a very high rate of abstinence, compared to other treatment programs. Other studies found that around 40 percent of homeless in abstinence-contingent housing maintained their abstinence, housing, and jobs.47 In a randomized controlled trial, homeless people were given furnished apartments and allowed to keep them unless they failed a drug test, at which point they were sent to stay in a shelter. Sixty-five percent of participants completed the program.48 Three similar randomized controlled trials also found moderate to high rates of completion. And participants in abstinence-contingent housing had better housing and employment outcomes than participants assigned housing for whom abstinence was not required.49 It turns out that over longer periods of time, Housing First may not even outperform contingency in terms of keeping people housed.

On average, a small but significant effect remained even after incentives were discontinued.27 It significantly increased participation in therapy, a key component of addiction recovery.28 Contingency management can also reduce psychiatric hospitalizations, improve financial management, and raise the quality of life for the mentally ill suffering substance abuse disorder.29 A large, randomized controlled trial among the seriously mentally ill, two-thirds of whom were homeless, found that the participants who received the contingency management intervention were 2.4 times more likely to be abstinent than the control group. Contingency management had a very low cost compared to other forms of drug treatment, just over $100 per week per participant.

A World Bank study of evaluation in 2000 began with the confession, “Despite the billions of dollars spent on development assistance each year, there is still very little known about the actual impact of projects on the poor.22 After years of pressure, the IMF created an Independent Evaluation Office in 2001. The World Bank in 2004 laudably created a Development Impact Evaluation Task Force. The task force will use the randomized controlled trial methodology discussed in chapter 2 to assess the impact of selected interventions on the intended beneficiaries. The task force has started two dozen new evaluations in five areas (conditional cash transfers in low-income countries; school-based management; contract teachers; use of information as an accountability tool for schools; and slum upgrading programs).

There is also the list of thirty-four indicators (none of which involves monitoring “core transmitters”), the nineteen-point terms of reference for the M&E consultant to the NAC, and the “summary terms of reference for specialized programme activity monitoring entity.” The accepted scientific standard for any program evaluation, the randomized controlled trial, did not make it into the manual. The Kitty Genovese Effect Winston Moseley killed Kitty Genovese, a twenty-eight-year-old bar manager, in Queens, New York, in 1964. Her murder is the first news story I remember from my childhood. As Moseley first stabbed Kitty, neighbors heard her screams but didn’t call the police.

Perhaps the aid agencies should each set aside a portion of their budgets (such as the part now wasted on self-evaluation) to contribute to an international independent evaluation group made up of staff trained in the scientific method from the rich and poor countries, who will evaluate random samples of each aid agency’s efforts. Evaluation will involve randomized controlled trials where feasible, less pure statistical analysis if not, and will at least be truly independent, even when randomized trials and statistical analysis are not feasible. Experiment with different methods of simply asking the poor if they are better off. Mobilize the altruistic people in rich countries to put heat on the agencies to make their money actually reach the poor, and to get angry when the aid does not reach the poor.

Allocation of treatment: It is important to compare like with like, so the treatment and comparison groups have to be as similar as possible. The best way to ensure this is by randomly allocating participants to be treated or not, and then seeing what happens to them – this is known as a randomized controlled trial (RCT). Statin trials do this with enough people so that the two groups should be similar in all factors that could otherwise influence the outcome, including – and this is critically important – those factors that we don’t know about. These studies can be huge: in the UK Heart Protection Study carried out in the late 1990s, 20,536 people at raised risk of a heart attack or stroke were randomly allocated to take either 40 mg of simvastatin daily or a dummy tablet.3 People should be counted in the groups to which they were allocated: The people allocated to the ‘statin’ group in the Heart Protection Study (HPS) were included in the final analysis even if they did not take their statins.

If both small and large values of T indicate inconsistency with H0, then the two-sided P-value is the probability of observing such a large value in either direction. Often the two-sided P-value is simply taken as double the one-sided P-value, while the R software uses the total probability of events which have a lower probability of occurring than that actually observed. quartiles (of a population): the 25th, 50th and 75th percentiles. randomized controlled trial (RCT): an experimental design in which people or other units being tested are randomly allocated to different interventions, thus ensuring, up to the play of chance, that the groups are balanced in both known and unknown background factors. If the groups show subsequent differences in outcome, then either the effect must be due to the intervention or a surprising event has occurred, whose probability can be expressed as a P-value.

Instead a small but vocal group of doctors and patients refused to accept these results, refused even to accept the designation of Post–Lyme Disease syndrome. They clung, instead, to “chronic Lyme disease” and insisted that these symptoms did reflect an ongoing infection that warranted continuing treatment with antibiotics. They countered the randomized controlled trials with research of their own, which often showed improvement in patients given antibiotics. But none of these studies compared the antibiotics against a placebo. The randomized controlled trials showed that while patients getting antibiotics did improve, so did those getting the saltwater placebo. Studies done without the placebo had no way of telling whether the antibiotics were really effective or if the improvement was due to something in the normal ebbs and flows of any human condition.

Blood tests have exploded in number and accuracy, providing doctors with tools to help make a definitive diagnosis in an entire alphabet of diseases from anemias to zoonoses. Better diagnosis led to better therapies. For centuries, physicians had little more than compassion with which to help patients through their illnesses. The development of the randomized controlled trial and other statistical tools made it possible to distinguish between therapies that worked and those that had little to offer beyond the body’s own recuperative powers. Medicine entered the twenty-first century stocked with a pharmacopeia of potent and effective tools to treat a broad range of diseases.

Obviously this is ridiculous, but they conducted a scientific experiment testing it anyway. They ran a randomized controlled trial in which they had each subject listen either to the Beatles song or to a control song. Remarkably, they found that while people who listened to each song should have been the same age, people who heard “When I’m Sixty-Four” were, on average, a year and a half younger than people who heard the control. Moreover, this difference was significant at the p < 0.05 level! Because the study was a randomized controlled trial, the usual inference would be that the treatment—listening to the song—had a causal effect on age.

Unlike previous observational studies, this study found that offering a wellness program had no statistically significant effect on healthcare costs or absenteeism, nor did it increase gym visits and similar types of physical activity. (The one useful thing that the wellness program did was to increase the fraction of participants who underwent a health screening.) The figure on this page summarizes these results. The randomized controlled trial found that being offered the wellness program had no effect on fitness activities, employee retention, or medical costs. But why? Previous studies largely found beneficial effects. Was there something particularly ineffective about how the Illinois wellness program was designed? Or did this point to selection effects in the previous studies?

Fiber Fueled: The Plant-Based Gut Health Program for Losing Weight, Restoring Your Health, and Optimizing Your Microbiome by Will Bulsiewicz

And in similar fashion, what if a high-fiber, plant-centered diet proved to be beneficial for other autoimmune, inflammatory conditions? Well, it does. In humans, a vegan diet has repeatedly been demonstrated to be beneficial for disease remission in rheumatoid arthritis. For example, in a randomized controlled trial 41 percent of patients on a vegan diet showed clinical improvement of their rheumatoid arthritis compared to just 4 percent on a “well-balanced” non-vegan diet. So not only do SCFAs correct dysbiosis and heal leaky gut, but they also create a powerful link between the microbiome and immune system that serves to make the immune system work properly.

In fact, whole-grain bread, whole-grain cereals, wheat bran, and brown rice were all found to be protective on sub-analysis, while white rice actually increased risk. I can’t write a gut health book without showing you what happens to your microbes when you consume whole grains. In a randomized controlled trial, study subjects who substituted whole grains for refined grains saw growth of SCFA-producing bacteria Lachnospira, increased SCFA levels, and a decrease in pro-inflammatory Enterobacteriaceae. They also noted improvement in the immune system and no effect on gut inflammation. In other words, whole grains were good for the gut.

Your blood pressure and cholesterol drop to the point of tapering your drug. Your blood sugar balances and the diabetes disappears. And your risk for having a heart attack or developing colon cancer just got chopped in half. There are literally hundreds of studies to support beans. Let me share just one example. In a randomized, controlled trial of a legume-packed diet versus legume-free, the researchers held the number of calories constant so that it was about nutrients and not calories. What they saw in the legume group was shocking. The C-reactive protein, a marker of inflammation, dropped by 40 percent. Blood pressure and cholesterol both dropped.

One is other drug use. That is, if cannabis is a gateway drug to the use of other drugs such as hallucinogens, then it may be the other drugs that are really contributing to schizophrenia, not the original cannabis use. Also, causation cannot be definitively established short of doing what is called a randomized controlled trial, in which cannabis would be administered to healthy young people at random who would then be followed to see who developed psychosis. Clearly this alternative is unethical. But the problem with the prospective cohort study is that people may have characteristics that increase risk for both the exposure and the outcome.

The annual incidence of symptomatic peripheral neuropathy associated with HIV/AIDS has been estimated at 36 percent (Schifitto et al. 2002), with estimates of the prevalence of neuropathy of 30 to 55 percent, rising with severity of disease (Husstedt et al. 2000). CANNABIS AND HIV-ASSOCIATED PAIN The treatment of pain is an important reason why many persons living with HIV use cannabis. To date, no randomized, controlled trials of prescription cannabinoid products for HIV-associated pain have been conducted, but there have been several studies of the safety and efficacy of smoked cannabis for HIV-associated peripheral neuropathy. Donald Abrams and his team pioneered the studies of cannabis and HIV/ AIDS with a safety study evaluating the effects of oral THC and smoked cannabis on plasma levels of antiretroviral medications.

At the same time, the bottom dropped out of funding sources for research on longer-term therapy, despite a strong clinical consensus about the importance of such research. In time we expect that this trend will be reversed and that more investigation of the effectiveness of psychotherapy in the real world of practice will be undertaken to supplement the knowledge accruing from randomized controlled trials of brief therapy. Another consideration is that, unlike in the physical sciences, many aspects of psychotherapy inherently defy quantification. Psychotherapy is both art and science; research findings may ultimately shape the broad contours of practice, but the human encounter at the center of therapy will always be a deeply subjective, nonquantifiable experience.

In development economics, new evidence has led to policy innovations in health, education, and finance that have the potential to improve the lives of hundreds of millions of people. Another way we can observe the transformation of the discipline is by looking at the new areas of research that have flourished in recent decades. Three of these are particularly noteworthy: behavioral economics, randomized controlled trials (RCTs), and institutions. What’s striking is that all these areas have been greatly influenced, and in fact stimulated, by fields from outside economics—psychology, medicine, and history, respectively. Their growth disproves the claim that economics is insular and ignores the contributions of other cognate disciplines.

I could take up the next tens of pages of this book outlining similar studies that have further confirmed what I’ve long thought to be true: vitamins don’t live up to the hype. But for fear of inundating you with too many academically minded summaries, let me briefly mention just a couple more that are more recent than those already described: • In 2010, the Agency for Healthcare Research and Quality published a review of sixty-three randomized, controlled trials (again, the gold-standard research method) on multivitamins, finding that multivitamins did nothing to prevent cancer or heart disease in most populations. The only exception occurred in developing countries where nutritional deficiencies are widespread. • In 2009, scientists at the Fred Hutchinson Cancer Research Center in Seattle, Washington, published a paper after following 160,000 postmenopausal women for about ten years.

Cancerous cells could already have started to propagate, at which point the inherent DNA repair system is no longer effective. It cannot fix the cancer. The clear association between inflammation and cancer is real and has many examples. One of the most exciting recent studies was published in the June 22, 2010, issue of the Journal of the American College of Cardiology. The analysis of two dozen randomized, controlled trials that were studying therapies for cholesterol found that each 10 mg/dl higher increment of HDL cholesterol (the good cholesterol) was associated with a relative 36 percent lower risk of cancer. The relationship persisted even after adjusting for LDL cholesterol (the bad cholesterol), age, body mass index (BMI), diabetes, sex, and smoking status.

Put another way, if you ignore all the investment funds that quietly disappear, the apparent performance is twice as good as the actual performance.28 The result is to persuade people to invest in actively managed funds, which often charge high fees, when they might be better served by a low-cost, low-drama fund that passively tracks the stock market as a whole. That is a decision worth tens of billions of dollars a year across the US economy; if it’s a mistake, it’s a multibillion-dollar mistake.29 So much for money. What about health? Consider the life-or-death matter of which medical treatments work and which don’t. A randomized controlled trial (RCT) is often described as the gold standard for medical evidence. In an RCT, some people receive the treatment being tested while others, chosen at random, are given either a placebo or the best known treatment. An RCT is indeed the fairest one-shot test of a new medical treatment, but if RCTs are subject to publication bias, we won’t see the full picture of all the tests that have been done, and our conclusions are likely to be badly skewed.30 For example, in 2008 a quick survey of studies of a variety of antidepressant medications would have found forty-eight trials showing a positive effect and three showing no positive effect.

If nothing else, that would provide an outlet for whistleblowers, “so that we’d have someone to complain to when our employer (Facebook, say) is asking us to do something we suspect is unethical or at least isn’t up to the standards of accountability that we’ve all agreed to.”35 Another parallel with the practice of medicine is that important algorithms should be tested using randomized controlled trials. If an algorithm’s creators claim that it will sack the right teachers or recommend bail for the right criminal suspects, our response should be “Prove it.” The history of medicine teaches us that plausible-sounding ideas can be found wanting when subjected to a fair test. Algorithms aren’t medicines, so simply cloning an organization such as the US Food and Drug Administration wouldn’t work; we’d need to run the trials over faster timelines and take a different view of what informed consent looked like.

But just as Madoff’s year-to-year differences in returns were too consistently small, too many of Sato’s baseline differences were implausibly close to zero to be explained by chance.36 This approach—comparing the pattern of baseline differences observed in a study or set of studies to what should happen if there were true random assignment—was originally developed by a British anesthetist named John Carlisle. He applied it to over 5,000 randomized controlled trials on anesthesia, 72 of which had already been retracted due to known data manipulation or fraud. Of those retracted papers, 43, or 60 percent, had the same problem that Sato’s did: too many consistently small baseline differences. Another 15 percent of the papers that were still part of the scientific literature failed Carlisle’s test as well, suggesting both that baseline consistency was a reliable sign of trouble and that more trouble still lurked in the field.

Even if you find a plausible connection between hiring Larry Taylor and an improvement in retention, there is no proof that his intervention caused that improvement. Business results aren’t like the randomized controlled trials used to evaluate medical treatments. There is no control group that got a “placebo consultation” against which to compare the success of Taylor’s clients. You would never expect that kind of data from firms pitching for your business, but you should keep in mind that only that kind of data can truly reveal how effective those firms are. 25.

It’s also a fallacy to think that randomized experiments are invalid unless all of the baseline differences are zero, but the fact that some researchers believe it may account for why fraudsters try to make up results that look that way. 36.

Brain Energy: A Revolutionary Breakthrough in Understanding Mental Health--And Improving Treatment for Anxiety, Depression, OCD, PTSD, and More by Christopher M. Palmer Md

The goal is to understand the physiology of mental disorders, enabling us to develop effective treatments, and ideally, prevent these disorders before they occur. Causation is proving that one thing causes another. Correlational studies on their own simply cannot do this. They can suggest causation, or at least provide clues, but proving causation requires something more. One type of study that can prove causation is called a randomized controlled trial. For example, to prove that the cold virus can cause a runny nose, researchers could take a group of people who are not sick, expose half of them to the cold virus by squirting the virus up their noses and the other half to a placebo (by squirting plain water up their noses). They could then record the number of people in each group who develop runny noses over the following five days.

If the cold virus causes runny noses, the group exposed to the cold virus should have a much higher rate of runny noses than the placebo group. In fact, these studies have been done, and this is true. One of the challenges in proving causation of a serious or life-threatening disorder in humans is that randomized controlled trials are unethical. Thus, even if we do have a plausible theory of what causes cancer, or mental illness, it will be unethical to expose people to this cause to test the theory definitively. So, what can be done in situations like this? Researchers are sometimes allowed to do equivalent experiments on animals.

Proving Effectiveness Long before Holden Karnofsky and Elie Hassenfeld wondered which organizations would make the best use of their donations, Esther Duflo and Abhijit Banerjee at the Massachusetts Institute of Technology founded the Jameel Poverty Action Lab on the premise that we can and should use scientific methods to find out which aid projects work. As the gold standard of scientific rigor they take the random controlled trial used for testing the efficacy of new drugs. In such a trial, half the patients are randomly assigned to receive the new drug, while the other half get a placebo. Randomization ensures that the two groups are not different in any way that could affect the course of their illness or the impact of the drug.

Thanks to controlled trials, we know that providing drugs to kill parasitical worms in Kenyan children improves learning, that education in condom use reduces the likelihood of people getting AIDS, and that offering mothers in India a cheap bag of lentils means that more of them will bring in their children for immunization.12 So why don’t we test all poverty programs this way? One reason is the cost of administering the trials. Oxfam America found that a random controlled trial of one of its microcredit programs in West Africa would cost almost as much as the project itself. The money would have come out of the budget for the project, with the result that microcredit could be extended to only half as many villages as would otherwise be possible. Oxfam did not go ahead with the randomized trial.

.* In his second trial, beginning in December 1948, Hill duplicated exactly the same experimental structure—same randomization, same X-ray evaluation—as his first. This time, however, he added Lehmann’s oxygen inhibitor to the treatment group. Less than a year later, the power of what would come to be known as RCT, for randomized controlled trials, was vindicated. The Medical Research Council announced that they had shown “unequivocally that the combination of PAS with streptomycin considerably reduces the risk of the development of streptomycin-resistant strains of tubercle bacilli.” The three-year survival rate using the combination of the two drugs was an almost unbelievable 80 percent.* In less than three years, penicillin and streptomycin had achieved more victories in the battle against infectious disease than anything in the entire history of medicine since Galen.

It allowed Frances Kelsey a remarkably free hand in exercising her authority to grant or withhold IND status; to her critics, this led to any number of cases in which she withheld classification based on nothing but a lack of faith in a particular investigator, or her judgment that the proposed drug was either ineffective or dangerous.* The new requirements, which would remain largely unchanged for at least the next fifty years, permanently altered the character of medical innovation. The method of validating medical innovation using randomized control trials had given the world of medicine a way of identifying the sort of treatments whose curative powers weren’t immediately obvious to clinicians (and, just as important, identifying those that seemed spectacular, but weren’t). Until 1963, however, RCTs had been a choice. The three phases of the newly empowered FDA made them a de facto requirement.

A few centuries later, these events would be immortalized in the biggest bestseller ever: the Bible (see Daniel 1:1–16). But it would still be several hundred years before this kind of comparative research came to be considered the scientific gold standard. These days, we would call this a randomized controlled trial, or RCT. If you were a medical researcher, you would proceed as follows: Using a lottery system, you divide people with the same health problem into two groups. One gets the medicine you want to test and the other gets a placebo.7 In the case of bloodletting, the first comparative experiment was published in 1836 by the French doctor Pierre Louis, who had treated some pneumonia sufferers by immediately relieving them of a few pints of blood and others by holding off on the leeches for a few days.

They don’t believe humans are rational actors. Instead, they assume we are quixotic creatures, sometimes foolish and sometimes astute, and by turns afraid, altruistic, and self-centered. And this approach appears to yield considerably better results. So why did it take so long to figure this out? Well, several reasons. Doing randomized controlled trials in poverty-stricken countries is difficult, time-consuming, and expensive. Often, local organizations are less than eager to cooperate, not least because they’re worried the findings will prove them ineffective. Take the case of microcredit. Development aid trends come and go, from “good governance” to “education” to the ill-fated “microcredit” at the start of this century.

Self-congratulatory studies, media hype, books and courses all feed off each other. The main problem of skewed research stems from the academic mindfulness industry, in which millions of dollars of grant money are at stake. Research support is most readily available for “evidence-based” studies that work with randomized-controlled trials (RCTs) — in theory, the gold standard of science. However, the problems with studies on mindfulness are not new. Before they started to receive grant funding in the last decade, there was a similar enthusiasm from government funding agencies for Transcendental Meditation (TM). Between 1992 and 2010, the US National Institutes of Health (NIH) awarded nearly $23 million to Maharishi University, the site for the majority of research on TM.

In another meta-analytic study published in the Journal of the American Medical Association (JAMA), Internal Medicine, Dr Madhav Goyal and his colleagues from John Hopkins University searched databases using a set of key meditation terms.17 They found 18,753 citations, of which forty-seven matched their inclusion criteria, such as the use of randomized controlled trials. They found that mindfulness was moderately effective in treating a variety of conditions, but not more effective than other active treatments, such as drugs or exercise. Moreover, the fact that only 0.25% of the studies were deemed of high enough quality should give one pause. Hype is the unsurprising outcome of such low standards of methodological rigor, despite the lukewarm findings they conceal.

A randomized study might make particular conclusions about the effectiveness of a medicine—but in truth it has only judged that effectiveness in the subset of people who were randomized. The power of the experiment is critically dependent on its strong limits—and this is the very thing that makes it limited. The experiment may be perfect, but whether it is generalizable is a question. The reverential status of randomized, controlled trials in medicine is its own source of bias. The BCG vaccine against tuberculosis was shown to have a potent protective effect in a randomized trial, but the effectiveness of the vaccine seems to decrease almost linearly as we move in latitude from the North to the South—where, incidentally, TB is the most prevalent (we still don’t understand the basis for this effect, although genetic variation is the most obvious culprit).

Daniel Paravisini and Antoinette Schoar examined a Colombian bank’s evaluation of small enterprise loan applicants after the introduction of a new credit scoring system.22 The computerized scoring system took a variety of information about the applicants and aggregated it into a single measure that predicted risk. Then a loan committee of bank employees used the score and their own processes to approve, reject, or refer the loan to a regional manager to decide. A randomized controlled trial, not management decree, determined whether the score was introduced before or after the decision. Thus, the score provided a good place to scientifically evaluate its impact on decision making. One group of employees was provided the score just before they met to deliberate. This is analogous to the first way to collaborate with a machine, in which the machine prediction informs the human decision.

The challenge is that you do not have the data on what would have happened had you not read the book. If you want to understand what causes what, you need to observe what would have happened in the counterfactual situation. Humans can provide two main solutions to this problem: experiments and modeling. If the situation arises often enough, you can run a randomized control trial. Assign some people to the treatment (force them to read the book, or at least give them the book and maybe hold some consequential exam on it) and others to the control (force them not to read the book, or at least don’t advertise it to them). Wait and collect some measure of how they apply AI in their work.

One doc may therefore get all the psychiatric cases on a shift, or all the elderly patients. Because an old person with shortness of breath is much more likely to die than a thirty-year-old with the same condition, we have to be careful not to penalize the doctor who happens to be good with old people. What you’d really like to do is run a randomized, controlled trial so that when patients arrive they are randomly assigned to a doctor, even if that doctor is overwhelmed with other patients or not well equipped to handle a particular ailment. But we are dealing with one set of real, live human beings who are trying to keep another set of real, live human beings from dying, so this kind of experiment isn’t going to happen, and for good reason.

Patients were assigned to the wards in alternating twenty-four-hour cycles, depending on the day of the week they arrived. Given the nature of pregnancy, an expectant mother came to the hospital when it was time to have the baby, not on a day that was convenient. This assignment methodology wasn’t quite as rigorous as a randomized, controlled trial, but for Semmelweis’s purpose it did suggest that the divergent death rates weren’t the result of a difference in patient populations. So perhaps one of the wild guesses listed above was correct: did the very presence of men in such a delicate feminine enterprise somehow kill the mothers?

Marion Sims, known as the “father of modern gynecology,” developed a groundbreaking cure for fistulas by practicing the surgery on enslaved women, whom he purchased specifically for that purpose, and later on poor Irish immigrants. In the twentieth century, medicine slowly but surely became more rooted in science. The post–World War II period saw the rise of modern clinical research—with its gold standard of the double-blind, randomized, controlled trial—and a huge influx of federal funding turned the United States into a world leader in biomedical research. But this expansion preceded any consensus that the patients involved in clinical research shouldn’t be treated as unwitting guinea pigs. At least through the sixties, it remained socially disadvantaged and/or institutionalized groups—like the poor, prisoners, soldiers, and the mentally ill—who were most likely to be used in medical studies.

But, the GAO report warned, a couple of large all-female studies, like the Women’s Health Initiative, can mask the fact that there may still be specific areas where women remain underrepresented: “By not examining more detailed data on enrollment—such as data aggregated by research area or specific to various diseases and conditions—NIH cannot know whether it is adequately including women across all of the research it supports.” Indeed, outside analyses of published NIH-funded studies tend to paint a slightly less than equal picture. A review of federally funded randomized controlled trials published in nine prominent medical journals in 2004 found that, on average, women made up 37 percent of the trial subjects. When the researchers redid the analysis for studies published in 2009—same journals, same methodology—there had been no improvement: 37 percent. And of course, the NIH, while the largest, is not the only funder in town.

I have worked on versions of a UBI to Rise for years—in 1994,56 in my 2005 book,57 and in 2012 when President Obama proposed a version.58 It is long past time to get it done. As part of that effort, we should provide workers with childcare, transportation subsidies, and other supports critical to completing a training program and finding a new career. A randomized controlled trial of sector-based employment programs in the United States found that “help with childcare or transportation or a referral for housing or legal services can be critical to staying in training or keeping a job.”59 UBI to Rise could also be structured to give workers a shot at starting their own business, a feature that would also be more effective if it was available before job loss hit.

Sectoral training programs provide skills for a specific industry or industries in a local economy, rather than for just one company, to enable mobility across companies. And they are often facilitated by intermediaries and developed with employers’ input to ensure that the credentials and skills developed are valued by the companies that will be hiring program graduates. We are now seeing hard evidence from randomized controlled trials that these types of programs are producing strong results in giving Americans second chances and potential careers. For example, the nonprofit Year Up provides young adults in urban areas with six months of training in IT or financial services, followed by a six-month paid internship at a major firm in that sector.

Indeed, 88 percent of the students who do not earn a high school diploma struggled with reading in the third grade.72 A large percentage of parents with means know well that individualized tutoring or coaching can be game-changing for children struggling to keep up or even excel enough to compete for selective colleges. Yet for many parents in even middle-class families—no less low-income families—an hourly tutor can be an unaffordable luxury. A randomized controlled trial evaluated the impact of two-on-one math tutoring in twelve low-income Chicago public schools in the 2013–14 academic year. Participating students received fifty minutes of math tutoring every school day by specially trained tutors organized through Match Education, now called SAGA.73 This innovation allowed Match to create a scalable model that public schools could adopt.

This was the first evidence to show that VR actually changes brain activity during painful procedures.9 Hoffman knew that in order to make VR pain treatments widespread he would have to convince hospitals and insurance companies to recognize VR’s effectiveness. So he and his colleagues, in 2011, took a critical step toward gaining credibility in clinical fields: a randomized controlled trial.10 These studies have larger samples and take great care to ensure the validity of the treatment and control conditions. Fifty-four hospitalized children—burn patients—participated in the study while doing physical therapy to treat the burns, which is a horribly painful experience in which the patients extend their range of motion by doing exercises.

Allocation of treatment: It is important to compare like with like, so the treatment and comparison groups have to be as similar as possible. The best way to ensure this is by randomly allocating participants to be treated or not, and then seeing what happens to them—this is known as a randomized controlled trial (RCT). Statin trials do this with enough people so that the two groups should be similar in all factors that could otherwise influence the outcome, including—and this is critically important—those factors that we don’t know about. These studies can be huge: in the UK Heart Protection Study carried out in the late 1990s, 20,536 people at raised risk of a heart attack or stroke were randomly allocated to take either 40 mg of simvastatin daily or a dummy tablet.3 3.

If both small and large values of T indicate inconsistency with H0, then the two-sided P-value is the probability of observing such a large value in either direction. Often the two-sided P-value is simply taken as double the one-sided P-value, while the R software uses the total probability of events which have a lower probability of occurring than that actually observed. quartiles (of a population): the 25th, 50th and 75th percentiles. randomized controlled trial (RCT): an experimental design in which people or other units being tested are randomly allocated to different interventions, thus ensuring, up to the play of chance, that the groups are balanced in both known and unknown background factors. If the groups show subsequent differences in outcome, then either the effect must be due to the intervention or a surprising event has occurred, whose probability can be expressed as a P-value.

Difficulties in measuring a drug’s risks can render strategic ignorance not simply a pernicious tactic, but rather a rational and even laudable response to the limits of scientific evidence. SHOW ME THE EVIDENCE Regulators and drug manufacturers rely on two main scientific methods for testing a drug’s efficacy and safety. Each of these methods has its own strengths and weaknesses. The first is the randomized controlled trial (RCT), first used to test the benefits of medicines in the 1940s. Since then, RCTs have become a vital pillar in efforts to measure the risks and benefits of new medicines, seen as the ‘gold standard’ because the use of randomly allocated control groups helps to determine whether the drug itself or an external factor – such as the specific physiology of individual patients, or environmental factors – is directly responsible for a particular treatment effect.

At the time of writing we don’t have any drug treatments that are really effective. One of the more promising is remdesivir, an antiviral drug that was first developed years ago to fight Ebola. It didn’t work that well against Ebola, but tests done in the lab suggest it may help prevent the Covid-19 virus from replicating. There has been one randomized controlled trial that showed that, on average, it reduces the time it takes to recover from Covid-19 from 15 days to 11 days. There was also a modest impact on the risk of dying, though this was not statistically significant.25 Another drug, which got a lot of attention from President Donald Trump after a small study done in France suggested it might be of benefit, is the anti-malaria drug hydroxychloroquine.

But the report concludes: It is not at all obvious that the rush to implement pre-k programs widely without the necessary attention to the quality of the program provides worthwhile benefits to children living in those disadvantaged environments. . . . Scaling up pre-k programs quickly could lead to badly run programs that might, in fact, be worse than doing nothing.34 A metastudy of 35 high-quality studies of ten much-studied preschool programs found that only half the studies used randomized control trials, the so-called gold standard of research. Of those, only three found statistically significant positive long-term results. But none of those results was linked to school-based pre-K.35 The study concludes: We know that parents and early environments play by far the most crucial role in shaping a child’s development. . . .

Though taking the loans was costlier than saving, it provided the households with an effective way to accumulate. 11. For an excellent presentation of these issues, we refer readers to Mullainathan 2005. 12. See Ashraf, Karlan, and Yin 2006. They evaluated the impact of this “commitment” saving product using a randomized controlled trial, where 1,800 customers of a bank were randomized to either receive an offer to open the new type of account or not. (Everyone already had access to a standard account.) Among those offered the new type of accounts, 28 percent opened one. After 12 months, average savings balances increased by 80 percent in the group offered the new type of account compared to the control group.

Foreign investment in microfinance, for example, more than tripled between 2004 and 2006, to $4 billion. See Reille and Forester 2008. 4. For a review of early experiences with branchless banking, see Ivatury and Mas 2008. 5. New field research adapts methods from medical research, particularly the use of randomized controlled trials, to test the value and logic of financial innovations. Recently, the Financial Access Initiative, a consortium of researchers at New York University, Yale, Harvard, and Innovations for Poverty Action, has been formed to extend field trials in Latin America, Africa, and Asia. Working with microfinance providers, researchers are investigating, for example, how sensitive borrowers are to changes in interest rates, the value of structured savings devices, and the impact of business training alongside credit.

But COX-1 protects the lining of the stomach, and its inhibition causes ulcers.11 Overdosage of NSAIDs is thus a leading cause of death among the elderly.12 Merck had the bright idea (as did Searle) to create a drug targeted to block COX-2, but not COX-1.13 Merck developed such a drug; named it Vioxx; and got it approved by the FDA. But that approval carried with it the further stipulation of a more rigorous randomized controlled trial than had been so far conducted.14 Merck named that study VIGOR (the VIoxx Gastrointestinal Outcomes Research study). The events surrounding VIGOR will give us a feeling for why, despite our modern safeguards, we are still vulnerable to phishing by Pharma. Like publishing houses bringing out a best-selling book, the Pharmaceuticals carefully orchestrate the rollout of a blockbuster drug.

In selecting the authors, who will receive the data from the experiments, the drug companies are not shooting in the dark. Their many connections (including those from the research support given by the company) clue them in: both regarding who will be influential and who will be favorable. The selectees are given easy access to the randomized controlled trials required by the FDA. They are also typically given “editorial support”—less graciously known as “ghostwriting”—for the article.15 It is thus no coincidence that a higher fraction of journal articles sponsored by pharmaceutical companies are favorable to the drugs reviewed than articles funded by other sources.16 Part of drug marketing is not just about the content of the articles published; it is also about their number.

In 2004, Leon Hempel and Eric Töpfer, writing from the Center for Technology and Society in Berlin, analyzed studies of closed-circuit television (CCTV) use in Europe and found that many of the studies lacked control groups to compare crime trends in the areas where cameras were installed to crime trends in the wider areas without cameras, and lacked analysis of the displacement of crime from the target areas to other areas. The few studies that have used control groups show little support for the theory that cameras can prevent crime. Another Urban Institute study from 2011 analyzing the impact of surveillance cameras on crime in parking lots—and using a randomized controlled trial method—showed that the cameras made no real difference. The study compared a year’s worth of car-related crime in twenty-five parking lots near Metro stations in Washington, D.C., that had installed motion-activated cameras with identical crimes in twenty-five similar “control” parking lots with no cameras installed.

Instead, the bot got me to reframe my issue in generalized terms that it could competently address. But that isn’t so different from what a real therapist does. When Woebot asked how I was doing after our little session, I had to admit that I felt better. Beyond subjective impressions, is there evidence supporting the efficacy of chatbot therapists? In a randomized controlled trial conducted by researchers at Woebot and the Stanford School of Medicine, seventy subjects were divided into two groups. Half were directed to get help from Woebot while the other half was instructed to consult an e-book about depression. After two weeks, all of them completed online mental health assessments.

In healthcare, AI systems are at risk of producing unreliable insights even when algorithms are perfectly implemented, because the availability of medical data is affected by social inequality. Poorer communities lack access to digital healthcare, which leaves a gaping hole in the medical information that is fed into AI algorithms. Randomized control trials often exclude groups such as pregnant women, the elderly, or those suffering from other medical complications.(34) Such exclusions mean that the unique physical characteristics of these patients are not incorporated into studies, which in turn affects whether tested treatment will be effective on patients who don’t share the characteristics of the original clinical volunteers.

Moreover, as other researchers had implied at the same conference, they couldn’t even know if the rats they used were good models for other rats, since some of the observations were what researchers would call “strain specific.” Eating sugar seemed to shorten the lives of some strains of rats but not others. The kind of randomized controlled trials over the course of ten or twenty years that would truly test the hypothesis that sugar caused heart disease or diabetes, as Yudkin noted, were no different from the kind the NIH was then considering and would soon reject for the dietary-fat/cholesterol hypothesis. Such trials were certainly far beyond the budget of any single researcher or even collaboration of researchers; they required that the National Institutes of Health or the Medical Research Council in the U.K. or some other government agency create a concerted program to test the idea.

In 2005, Scottish researchers reported that diabetic patients who took a drug called metformin, which works to reduce insulin resistance and therefore lower circulating levels of insulin, also had a significantly reduced risk of cancer compared with diabetics on other medications. That association has been confirmed multiple times, and has led researchers to test whether metformin acts as an anti-cancer drug, preventing or inhibiting cancer’s recurrence in randomized controlled trials. These observations also served to focus the attention of cancer researchers further on the possibility that insulin and insulin-like growth factor are cancer promoters, and thus that abnormally elevated levels of insulin—caused by insulin resistance, for instance—would increase our cancer risk.

Alex Berger, one of my classmates, had gotten involved in effective altruism, a philosophical and social movement that advocates for “using evidence and reason to figure out how to benefit others as much as possible, and taking action on that basis.”27 Alex told me about GiveDirectly, a nonprofit organization operating in East Africa—primarily Kenya, Uganda, and Rwanda—that helps families living in extreme poverty by making unconditional cash transfers to them via mobile phone.28 The program has expanded significantly: in 2019, GiveDirectly provided a total of $33 million to forty thousand households.29 Part of what has enabled GiveDirectly’s growth is that the organization measures its impact using randomized control trials. Studies have shown that when households receive a grant from GiveDirectly, they buy more food and do not increase spending on vices like alcohol or tobacco.30 There is also evidence that recipients can invest cash transfers at high rates of return—about 20 percent per year—which enables long-term increases in individual and community wealth.31 Transfer recipients also see major improvements in their psychological well-being, including reductions in the stress hormone cortisol, which is associated with improved quality of life and longevity.

The Stockton Economic Empowerment Demonstration (SEED)—the first mayor-led guaranteed income demonstration—showed the power of providing people in poverty with more resources to meet their basic needs. Launched in 2019 by then mayor Michael Tubbs, SEED gave 125 residents in Stockton, California, $500 per month for twenty-four months with no strings attached.32 Like GiveDirectly’s cash transfers, SEED was found in a randomized control trial to be beneficial. Recipients were more likely to find full-time employment; were healthier, with less depression and anxiety and enhanced well-being; and were able to pursue new opportunities for self-determination, goal setting, and risk taking. Individuals spent most of the money on basic needs, including food, clothing, utilities, and automobile expenses; less than 1 percent was spent on alcohol or tobacco.

Third, new information flows and increasing transparency can help shift citizen behaviour on a large scale, as it becomes the path of least resistance within a new set of business and social norms for a sustainable circular system. Fruitful convergence between the fields of economics and psychology has been producing insights into how we perceive the world, behave and justify our behaviour, while a number of large-scale randomized control trials by governments, corporations and universities have shown that this can work. One example is OPower, which uses peer-comparison to entice people into consuming less electricity, thereby protecting the environment while reducing costs. Fourth, as the previous section detailed, new business and organizational models promise innovative ways of creating and sharing value, which in turn lead to whole system changes that can actively benefit the natural world as much as our economies and societies.

These studies are then followed by phase 2 studies, which involve slightly larger numbers of subjects and attempt to further explore the safety of the drug and, more important, get an initial sense of its efficacy. If this phase is promising, then phase 3 studies, involving a much larger number of people in a randomized controlled trial, are initiated with an eye to quantifying the actual efficacy of the drug. In such pivotal phase 3 studies, one group of people is randomly assigned to get the active agent and another, the control group, gets either a placebo or whatever constitutes the usual standard of care. During phase 3, scientists also assess the possible emergence of rare toxicities that could not have been observed in the small phase 1 and phase 2 studies.

In 1995, after much effort, a drug known as saquinavir (a protease inhibitor) was discovered. It became part of a three-drug regimen—composed of saquinavir, dideoxycytidine (ddC), and AZT—a combination called highly active antiretroviral therapy, or HAART. In 1996, results from two pivotal randomized controlled trials, involving a total of over twelve hundred volunteers and supported by NIAID, showed that HAART was extremely effective.93 Though the side effects were considerable and the daily dosing regimens very complex, it was lifesaving. With HAART, many patients saw the viral load of HIV in their blood become undetectable.

Both our analyses and larger national-level studies indicate that much of the violence experienced by ordinary villagers was effectively random. Militias would storm into a community, spraying bullets in all directions, and then torch the most conveniently located houses as villagers either hid or fled. This means that, as in the randomized control trials used to test the effectiveness of new medicines, individuals were largely afflicted by, or “dosed with,” war-related violence at random. This quasi-randomization allows us to cautiously infer that war is in fact causing the psychological changes captured in our experiments.3 FIGURE 10.1.

Things like acetaminophen and nonsteroidal anti-inflammatory drugs have virtually no effect in pain amplification syndromes. Opioids also do not seem to work well,” comments Dr. Clauw. “The best drugs for these syndromes are those that act on the central nervous system, like tricyclic antidepressants. Some randomized controlled trials indicate that medications that act on the 352 The Autoimmune Connection neurotransmitters serotonin and norepinephrine are among the most effective.” Aerobic exercise acts as a natural painkiller and an antidepressant, he adds. Antidepressant medications can help reduce pain signals from nerves and aid sleep.

“However, given the fact that fibromyalgia is a neural pain amplification syndrome, it’s unlikely that nutritional factors play a really prominent role,” remarks Dr. Clauw. Cognitive behavioral therapy (CBT) teaches coping skills and behavioral changes to help you manage an often-frustrating illness. “Every randomized, controlled trial of cognitive behavioral therapy in any chronic illness has Fibromyalgia, Chronic Fatigue, Endometriosis, and Interstitial Cystitis 355 shown it to be effective,” says Dr. Clauw. For women with fibromyalgia, a pain-based CBT program can be especially effective. In CBT, you’ll learn relaxation techniques (such as deep breathing and positive visual imagery), how to reframe negative thoughts and behaviors that intensify pain responses, how to effectively solve problems, and how to pace activities to accommodate whatever limitations you may have.

On fairly conservative assumptions, they predict five dollars of savings from each dollar spent on well-crafted campaigns.6 The second problem is on the supply side, in particular a lack of knowledge or training among health professionals. Indeed, staff training alone seems to have a significant impact on the take-up of LARCs, according to a randomized control trial. The work of organizations like Upstream training providers in states including Ohio, New York, Texas, and Delaware is extremely promising.7 Other steps can be taken to broaden access, including ensuring sufficient supplies in health clinics, simplifying billing procedures, and providing same-day service.

In 2011, GiveDirectly’s leadership enlisted independent researchers affiliated with MIT’s Poverty Action Lab to assess the impact of their transfers. The analysis was done in coordination with the independent nonprofit Innovations for Poverty Action and the National Institutes of Health. The study analyzed the impact of cash transfers using a randomized control trial, the same methodology that pharmaceutical companies use to assess the power of a new drug and its side effects. The researchers surveyed recipients before they received the money to establish a baseline and again afterward to understand the impact. They then compared those villages to a set of “control” villages that did not receive transfers.

Secondary education has been much less researched but informal evidence indicates a similar picture.9 The big question that arises is why expansion in educational inputs has not been translated into better educational outcomes. There has been quite a lot of high-​quality research on this, based [ 178 ] Stability and Inclusion 179 on econometric work with nationally representative data sets, and on ‘randomized control trials’. (Again, the rigorous scholarly studies are mostly about primary education.)10 My reading of what these studies show is that the poor educational outcomes are the product of inappropriate incentives. The faulty incentives relate partly to prevailing pedagogic practice. Teaching in Indian schools is curriculum-​driven to an absurd degree; the over-​riding objective of teachers is to ‘finish’ the curriculum of each year even if the majority of students are falling behind.

There are complex technical and logistical issues to be sorted out. It may also be feared that rent-​ losers from the process would stymie the operation of the package in one way or another. It is very pertinent, therefore, that the merits of harnessing the new technologies have been demonstrated by Karthik Muralidharan and his associates in a randomized control trial that examined the delivery of NREGS wage payments into bank accounts via the introduction of ‘smart cards’, in a setting large enough to be policy-​relevant, viz. 158 sub-​districts (mandals) of Andhra Pradesh with 19 million people.16 In the ‘treatment’ mandals, the new system was introduced two years before it was in the ‘control’ mandals (in which payments continued to be disbursed in the old way).

The two subsequently joined forces with Frank Moss, director of the MIT Media Lab, and out of that collaboration came thelamfoundation.org, a website that allows patients to report on their health. The data in the reports are aggregated and analyzed to aid researchers in mapping out new research scenarios. This crowdsourcing approach to research differs substantially from traditional randomized controlled trials used in conventional research, which are expensive and time consuming and conceived of and carried out by researchers from the top down, with patients serving as passive subjects. The LAM site, like other research efforts on the health-care Commons, starts with the patients’ collective wisdom, which helps determine the research protocols.

So professional research has a built-in lethal lag time—a period of delay between the time some people know about an important medical breakthrough and the time everyone knows.60 While double-blind, controlled clinical studies are extremely expensive, patient-initiated observational studies using Big Data and algorithms to discover health patterns and impacts can be undertaken at near zero marginal cost. Still in its infancy, this open-source approach to research often suffers from a lack of verification that the slower, time-tested professional review process brings to conventional randomized control trials. Advocates are aware of these shortcomings but are confident that patient-directed research can begin to build in the appropriate checks, much like Wikipedia does in the shakeout process of verifying and validating articles on its websites. Today, Wikipedia has 19 million contributors. Thousands of users fact check and refine articles, assuring that the open-source website’s accuracy is competitive with other encyclopedias.

The evidence physicists relied on for the existence of the Higgs boson in 2012 would occur randomly less than once in 7 million trials were the Higgs boson not to exist. The drug approval process used by the United States Food and Drug Administration (FDA) also uses tests of significance. If a pharmaceutical company claims that a new drug reduces the severity of eczema, that company must run two randomized controlled trials. To construct a randomized controlled trial the company would create two identical populations of eczema sufferers. One of the populations receives the drug. The other population receives a placebo. At the end of the trial, the average severity as well as average rates of negative side effects are compared.

The GiveDirectly experiment is fascinating on two fronts: It is crowdfunded by ordinary people, who already use the platform to provide aid in the form of direct cash transfers to the needy; and in a developing country, the costs are lower so the program can be more extensive, and thus allows for a true randomized control trial. These experiments tell us how far the idea has come since it was proposed by Thomas Paine in 1795, and more recently by Milton Friedman in 1962 (and Paul Ryan in 2014). There are many arguments against UBI, most notably the cost of making it truly universal, and that providing the income to people whether they need it or not will starve existing programs that provided targeted aid to those who actually need it.

That tendency to ignore the need for statistical verification is only now beginning to change, with the slow and often grudging acceptance that we need more than a plausible anecdote (a single wave) before instituting a new policy for reoffenders, for teaching methods, for health care, or any other state function. Politicians are among the most recalcitrant, sometimes pleading that the genuine pressure of time, expense, and public expectation makes impossible the ideally random-controlled trials that would be able to identify real stripes from fake, sometimes apparently not much caring or understanding, but, one way or another, often resting their policies on little more than luck and a good story, becoming as a result the willing or unwilling suckers of chance. A politician with a taste for a calculated gamble is a disappointingly welcoming way in for chance to do its dirty work.

As recently as ten years ago, development stakeholders had no real way to test whether solutions like free school lunches actually get kids into the classroom—just counting the number of kids before and after doesn’t determine causality. And they definitely didn’t know whether free lunches were better and cheaper than alternative programs, such as conditional cash transfers, deworming medications to reduce illness, or free uniforms. Kremer saw a solution in the randomized controlled trial (RCT), the research method used by pharmaceutical companies to determine whether a drug is effective or not. Kremer was one of the first social scientists to design an RCT to test a social program, helping start a movement that has since become the gold standard in social research.1 (As it turns out, school-based deworming programs are the cheapest and most effective way to get poor kids to go to school.)

At CREDO I learned from my boss Michael Kieschnick to think big, to manage people and campaigns with tough love, and to look to science and testing to ensure resources were best deployed in the often asymmetrical battles waged from the progressive flank. It was through Michael that I was first introduced to the quantitative political scientist Donald Green. Green was among the first academics to apply randomized control trial methodology to the study of American voting behavior. His field experiments and field experiments inspired by his work have led to a hugely influential and growing body of science-based evidence detailing which voter turnout tactics have the greatest impact at the lowest cost. Research shows that, contrary to the conventional wisdom, the big money approach to elections isn’t what really moves voters.

Ask most research physicians how a profession can advance, and they will tell you about the model of "evidence-based medicine"--the idea that nothing ought to be introduced into practice unless it has been properly tested and proved effective by research centers, preferably through a double blind, randomized controlled trial. But in a 1978 ranking of medical specialties according to their use of hard evidence from randomized clinical trials, obstetrics came in last. Obstetricians did few randomized trials, and when they did they largely ignored the results. Take fetal heart monitors. Careful studies have found that they provide no added benefit in routine labors over having nurses simply listen to the baby's heart rate hourly.

While in New Orleans, I attended a research presentation where the final results of the international siltuximab clinical trial of seventy-nine iMCD patients were revealed. It was a huge occasion for the community—but somewhat uncertain in its implications. Dr. van Rhee was the lead investigator, and a number of other CDCN members were involved in the trial. It was the only randomized controlled trial, the gold standard test of efficacy in medicine, ever done in iMCD. This was historic. Just over a third of patients treated with siltuximab achieved a partial or complete response, compared to 0 percent on a placebo. And the drug was very well tolerated, with minimal side effects. The data were clear: Patients got better at a significantly higher rate on siltuximab than with a placebo.

For several reasons, the recent past has seen a vast amount of careful, detailed empirical work in economics. Computers mean many more data sets have been created, accessed, and shared. Statistical techniques for analysing economic data have improved, and techniques such as experiments and randomized control trials have become more widely used. There is always a need for greater care, but the interaction of theory and evidence is central to advancing understanding. It is an irony that all this work, flooding out daily in working papers, and including interaction with other disciplines such as psychology, epidemiology, engineering, and history, is being undertaken without much changing the public image of economics as being so dismal.

It has lost its stigma of ‘shirking from home’; first-timers often find it to be better than they expected; and some of us have invested in home offices, better equipment and internet, or even a new house. Employers will cut down on office costs and may get wider access to talent if their employees don’t have to commute.33 We don’t yet know if this will improve decision making. A randomized controlled trial that followed 1,000 employees over a nine-month period at a Chinese travel company found a 13% increase in performance and a 50% decrease in staff quitting. But data from mid-pandemic shows that there are winners and losers. The University of Chicago found that higher earners, highly educated workers and those with fewer dependents and larger homes disproportionately value home working.

Duncan and Magnuson (2013): 119. 24. The paragraph continues: In general, a finding of meaningful long-term outcomes of an early childhood intervention is more likely when the program is old, or small, or a multi-year intervention, and evaluated with something other than a well-implemented RCT [random controlled trial]. In contrast, as the program being evaluated becomes closer to universal pre-K for four-year-olds and the evaluation design is an RCT, the outcomes beyond the pre-K year diminish to nothing. I conclude that the best available evidence raises serious doubts that a large public investment in the expansion of pre-K for four-year-olds will have the long-term effects that advocates tout.

HUD seeks to alleviate some of the burden of the high housing costs faced by low-income families through maintaining public housing developments and through the housing choice voucher program, colloquially known as Section 8. While these programs are far from perfect, there’s solid evidence from the gold standard of social science research—a randomized control trial—that they reduce housing instability considerably. Access to a Section 8 voucher, in particular, reduces the chances that a family will be homeless—either doubled up or out on the streets. It lessens by half the share of families living in overcrowded units, and it greatly diminishes the average number of moves a family makes over a five-year period.

As with so many major scientific breakthroughs, it is impossible to specify who exactly got there first, for the simple reason that neither quite understood where exactly they had got to. The era of psychopharmacology was still very young, with the discovery of the first drug effective against schizophrenia in 1952 and the running of the first successful ‘randomized control trials’ (whereby a drug is tested alongside a placebo, with the recipients not knowing which one they’ve received) on Valium in 1954. These breakthroughs opened up a new neurochemical terrain for psychiatrists to explore. Unlike the developers of those anti-anxiety and anti-schizophrenia drugs, Kline and Kuhn were not sure precisely what disorder they were seeking to target.

Weil spells it all out in Healthy Aging: To many, faith is simply unfounded belief, belief in the absence of evidence, and that is anathema to the scientific mind. There is a great movement toward “evidence-based medicine” today, an attempt to weed out ideas and practices not supported by the kind of evidence that doctors like best: results of randomized controlled trials. This way of thinking discounts the evidence of experience. I maintain that it is possible to look at the world scientifically and also to be aware of nonmaterial reality, and I consider it important for both doctors and patients to know how to assess spiritual health. (Italics added.) Evidence of experience?

By forcing physicians to follow set rules, evidence-based medicine “can impede scientific progress,” he writes. Should hospitals and insurers “mandate EBM, backed up by the threat of lawsuits if adverse outcomes are accompanied by any departure from best practices, physicians will become reluctant to try alternative treatment strategies that have not yet been evaluated using randomized controlled trials. Scientific advancement can become stifled if front-line physicians, who blend medical expertise with respect for research, are prevented from exploration and are discouraged from making discoveries.”53 If we’re not careful, the automation of mental labor, by changing the nature and focus of intellectual endeavor, may end up eroding one of the foundations of culture itself: our desire to understand the world.

Scientists look at a large group of people—some of whom practiced one behavior and others another—and then they study the outcomes, attempting to make the groups equal with respect to other variables, with men and women of roughly the same age in each group, who share similar lifestyles in terms of their diet and exercise habits. These large, randomized controlled trials are the best resource we have to identify behaviors that can alter our risk for disease. The problem is that it is very hard to dictate behavior to a group of people and expect them to be compliant for years and then study an outcome that has a very long lag time, meaning time until the desired effect is seen.

So we need to be a little more specific about what generosity of spirit implies. What should it mean in the context of Syria, and, by extension, what should it mean more widely in the global context of refugees? Science makes progress through experiments. The natural sciences rely upon lab experiments; medicine and economics progress through randomized controlled trials and natural experiments. None of these approaches are of much use for the present question, but moral philosophy does have its own form of experiment: the thought experiment. We can use thought experiments to make progress in teasing out what we should mean by generosity of spirit. In this chapter we are going to focus on a series of ethical questions.

Willett and the paper’s authors both emphasized that nineteen people in a subsample were almost eight pounds below their initial weight thirty months after the start of the study.

Those with strong priors in favor of financial market efficiency, such as Eugene Fama, for example, can continue to absolve financial markets from culpability for the crisis, laying the blame elsewhere. Keynesians and “classical” economists can continue to disagree on their interpretation of high unemployment. But even in microeconomics, where it is sometimes possible to generate precise empirical estimates using randomized controlled trials, those estimates apply only locally to a particular setting. The results must be extrapolated—using judgment and a lot of hand waving—in order to be applied more generally. New economic evidence serves at best to nudge the views—a little here, a little there—of those inclined to be open-minded.

The church interprets the Bible literally, believes in Young Earth creationism, denies evolution, and believes prayer can substitute for medical care. For most of his life, Science Mike firmly believed these things. However, in his thirties he began reading scientific literature and his faith in these beliefs began to waver. He read about randomized control trials that cast doubt on the healing power of prayer, physics research that identified the true age of the universe, and biology and paleontology studies that support evolution. His initial reaction was to completely lose his faith, but for a long time he hid his new beliefs from his community.

Instead of swallowing the supplement, she just let it dissolve in her mouth, and the cold seemed to disappear within hours.2781 This observation led her own father to conduct the first randomized double-blind placebo-controlled trial on zinc lozenges.2782 There have since been more than a dozen randomized controlled trials published. Overall, researchers have found that zinc is indeed beneficial in reducing both duration and severity of the common cold when taken within the first twenty-four hours of symptom onset.2783 Zinc lozenges appear to shorten colds by about three days,2784 with significant reductions in nasal congestion and discharge, hoarseness, and cough.2785 The common cold results for zinc are often described as “mixed,” but that appears to be largely because some studies used zinc lozenges containing ingredients like citric acid that strongly sequester zinc, so little or no free zinc is actually released.2786 Lozenges containing around 10–15 mg of zinc as either zinc acetate or zinc gluconate without zinc binders such as citric acid, tartaric acid, glycine, sorbitol, or mannitol2787 taken every two waking hours for a few days starting immediately upon symptom onset may work best.2788 Best for the common cold, but what about COVID-19?

The government needs to privatize state-owned industries, enforce property rights, lower taxes, and reduce regulation. Get the economy going, and inequality will take care of itself. TECHNOCRATIC MIDDLE: We need an economy carefully regulated by internationally trained experts, targeted interventions that have been tested by randomized controlled trials, and political reform that protects human rights. People in rich countries, where inequality is rising, will recognize Brazil in their own countries. In the rich countries, economies are also stagnating and political conflict and corruption are on the rise. The long-standing belief that a “developing country” like Brazil will eventually end up as a “developed country” like the United States is under scrutiny, and people are beginning to wonder if things are moving in reverse.

Though he didn’t say it explicitly, the clear implication was that my assessment was being influenced by money. In the end, the committee decided to restrict Natrecor use to me (the resident heart failure specialist) and a handful of other cardiologists. By then I’d tapered off the talks anyway, and soon afterward I quit the speakers’ bureau. (A randomized, controlled trial later showed that Natrecor was safe but no more effective than existing, cheaper therapies.) During the two years I gave these talks, I often thought of what Jacob Hirsch, a cardiologist at NYU, once told me when we were sitting in the echo reading room during my fellowship. He was eating a sandwich that had been brought in by a drug rep.

The Reams case is a tragic reminder of what can happen when kids in places like Pine Bluff get help only from gangs: in this case, Turner was murdered, Reams spent twenty-five years on death row and Arkansas devoted scarce tax dollars to prisons, police, lawyers and courts instead of educating children and directing them to become, say, police officers rather than criminals. Because the cost of crime is so high, the evidence is that programs like Annette’s targeting at-risk kids can generate huge returns. One randomized controlled trial looking at a similar program in Chicago, Becoming a Man, found that the program reduced violent crime arrests by about half and increased high-school graduation rates by about 15 percent. The study showed that each dollar invested in the programs saved up to $30 over time. These programs should be replicated all across the country, so as to help young people and the country itself.

Chemical treatments like “embryo glue” and surgical procedures like “womb scratching” had been rolled out in the clinic before they were scrutinized according to rigorous scientific standards, she said. “I would call it a scandal at the moment with assisted reproductive technologies. I think that it is very strange that things were brought into the clinic without randomized control trials.” Now it is routine to inject sperm into an egg as part of standard fertility treatments, but this procedure was discovered by mistake. “The needle went in accidentally,” said O’Neill. The resulting embryo looked healthy, so it was later transferred by a different doctor. No rigorous tests were conducted, but after this accident, sperm injection “was just taken up as a new practice.”

It would arrive automatically to everyone who filed a tax return (which could prove to be a big asterisk, especially for people who work in the informal economy). The money would be mailed out in monthly checks, $250 per child over age six and $300 per child under age six, beginning in July 2021. In the past decade, randomized controlled trials have tested the effects of direct cash assistance, sometimes called universal basic income programs. These studies show that when people get reliable income, it tends to make their lives better. They spend more than before on fresh fruit and vegetables and less on alcohol and cigarettes.

If there’s a big difference between their improvement and the better improvement of the people with the real device, you move on to bigger and bigger trials to determine, to ever greater precision, whether the effect of your device is real and how big it is. Neurosurgeon Scott Shapiro methodically went about planning all of these next steps. He recruited three more neurosurgeons at other medical centers that had agreed to take part in the next small randomized controlled trial. And after that, his plan was to approach the NIH to fund a slightly bigger trial of eighty patients, forty of whom would receive a functional OFS. To Shapiro, the next steps were clear, and they had to be done in order. That wasn’t how Borgens saw it. He was getting older, and he had been carrying out this work now for the better part of twenty-five years.

A few years before the outbreak, one of London’s water suppliers had moved its intake point upstream from the main sewage discharge on the Thames, while another company kept its intake point downstream from the sewage. London had been divided into two groups, one drinking sewage and one drinking purer water. In other words, the London cholera outbreak was the result of something like an unintentional randomized controlled trial of disease theory. Several hundred thousand people were randomly distributed water from one company and were more likely to get sick, while several hundred thousand people were randomly distributed water from another company and stayed healthy. the healthy brewers: Randy Alfred, “Sept. 8, 1854: Pump Shutdown Stops London Cholera Outbreak,” Wired, September 8, 2009, www.wired.com/2009/09/0908london-cholera-pump/.

“Students who gain access to a home computer between the 5th and 8th grades tend to witness a persistent decline in reading and math scores,” the economists wrote.

Now a professor at the University of Michigan and author of Geek Heresy: Rescuing Social Change from the Cult of Technology, he tells an interviewer that, “[g]enerally, what most of these studies show is that schools with laptops did not see their children gain anything in terms of academic achievement, in terms of grades, in terms of test scores, in terms of attendance, or in terms of supposed engagement with the classroom.”53 Why would One Tablet, One Child be any different?

Politicians and civil servants too seldom appreciate how tools drawn from both the natural and social sciences can be used to design more effective policies, and even to win votes. In education and criminal justice, for example, interventions are regularly undertaken without being subjected to proper evaluation. Both fields can be perfectly amenable to one of science’s most potent techniques—the randomized controlled trial—yet these are seldom required before new initiatives are put into place. Pilots are often derisory in nature, failing even to collect useful evidence that could be used to evaluate a policy’s success. Sheila Bird, of the Medical Research Council, for instance, has criticized the UK’s introduction of a new community sentence called the Drug Treatment and Testing Order, following pilots designed so poorly as to be worthless.

Peak: Secrets From the New Science of Expertise by Anders Ericsson, Robert Pool

The program uses the same basic principles found in deliberate practice: breaking learning down into a series of well-specified skills, designing exercises to teach each of those skills in the correct order, and using feedback to monitor progress. According to teachers who have used the curriculum, this approach has allowed them to teach the relevant math skills to essentially every student, with no one left behind. Jump was evaluated in a randomized controlled trial in Ontario with twenty-nine teachers and approximately three hundred fifth-grade students, and after five months the students in the Jump classes showed more than twice as much progress as the others in understanding mathematical concepts as measured by standardized tests. Unfortunately, the results of the trial have not appeared in a peer-reviewed scientific journal, so it is hard to judge them objectively, and we will need to see the results reproduced in other school districts before we can trust them completely, but the results agree with what I have observed generally in a variety of fields, not just singing and math, but writing, drawing, tennis, golf, gardening, and a variety of games, such as Scrabble and crossword solving: People do not stop learning and improving because they have reached some innate limits on their performance; they stop learning and improving because, for whatever reasons, they stopped practicing—or never started.

Randomization even allows for unknown factors to be balanced equally across the groups. Fairness through randomization is particularly effective if the initial pool of participants is large. In this case, the number of participants (366 patients) was impressively large. Today medical researchers call this a randomized controlled trial (or RCT) or a randomized clinical trial, and it is considered the gold standard for putting therapies to the test. Although Hamilton succeeded in conducting the first randomized clinical trial on the effects of bloodletting, he failed to publish his results. In fact, we know of Hamilton’s research only because his documents were rediscovered in 1987 among papers hidden in a trunk lodged with the Royal College of Physicians in Edinburgh.

The opioid story fits with this more general theme but is much more flagrant, because it is rare that corporations can so directly benefit from death. We do not believe that the FDA has been captured by the industry. Even so, much went wrong with its approval of opioids, especially OxyContin. The FDA (and the general public) greatly reveres the randomized controlled trials that are required to demonstrate that drugs work, but even here there were problems with opioids. Those who were in the control group for OxyContin—the randomly selected group that did not receive the drug—had previously been taking OxyContin in an earlier phase of the trial, called the open-label phase; this is done to exclude from the trial those who cannot tolerate the drug.37 In this type of trial there is a “washout” period between the two phases, in which the drug is supposed to wash out of the patients’ systems.

Hence new experiments, perhaps in the form of randomized controlled trials, may be justified. See, for example, Abhijit Banerjee and Esther Duflo, Poor Economics (New York: Public Affairs, 2012). As a general rule, however, I think that development economics tends to neglect actual historical experience, which, in the context of this discussion, means that too little attention is paid to the difficulty of developing an effective social state with paltry tax revenues. One important difficulty is obviously the colonial past (and therefore randomized controlled trials may offer a more neutral terrain). 50.

They do not help us understand the recent acceleration of development progress or the reasons why so many developing countries began to turn at roughly the same time in the 1990s. The second field of research has been the opposite: microlevel studies on the effectiveness of specific actions and programs in particular contexts, often evaluated through rigorous randomized controlled trials (RCTs).III These studies focus on questions such as the impact of pricing on the uptake of insecticide-treated malaria bed nets, whether identity cards reduce theft and improve the delivery of subsidized rice to the poor, and the impact of shouting at bus drivers to get them to drive more safely.

The accuracy of a tool is not necessarily correlated with its efficacy in the world because the ultimate decision-making authority in most contexts still rests with human beings. So to understand efficacy, we need to observe how human beings interact with algorithmic predictions. One strategy would be to run some sort of experiment, ideally a randomized controlled trial; for example, identify a set of counties and randomly assign half to make bail decisions via algorithmic predictions (treatment group) and the other half to rely on judges’ decisions (control group). With a sufficient number of counties, you could then track the likelihood that individuals would show up to court and the rate at which defendants commit crimes in the two groups.

Everyone at the company had long understood that Facebook now had the tools to directly influence how people communicated, how they acted, and even how they felt. As Facebook grew from a few thousand users to a few billion, the sheer scale of these effects became terrifying to conceive. To answer the question, the Facebook researchers conducted an experiment on the 2010 midterm elections in the United States. The experiment came in the form of a randomized control trial, where the researchers randomly assigned sixty-one million (unknowing) users to different groups and subjected them to differing treatment. The first group, called the “social message” group, was shown a statement at the top of their News Feed encouraging them to vote and showing pictures of other friends who had voted.

This is called “a path model or a structural equation model” and it “goes from extrinsic materialistic values to low need satisfaction, to low levels of well-being.” When we take all these pieces of evidence together, I believe we can draw some fairly robust conclusions—but it is important to state that you simply can’t do a randomized control trial, so this doesn’t meet the very highest bar of evidence. He also pointed to evidence he has gathered that causation also appears to run the other way—depression and insecurity (especially in childhood) seem to trigger more materialism. The causation does not only run in one direction: It runs both ways.

I recently served as a mentor to an organization called Khushi Baby, which has developed a low-cost wearable amulet to store a baby’s unique identifier and capture the baby’s health-care data across multiple events during the early years of life. The product is currently undergoing its first deployment and randomized controlled trial in more than seventy villages in Udaipur, India. The key to its appeal does not come from any technical innovation—all the technologies are remarkably basic—but rather from a novel design mothers can relate to. The approach started with talking to hundreds of mothers in villages and observing children wearing amulets on a black thread to ward off disease.

Keith Rabois, Thiel’s old friend from Stanford, tweeted endlessly about the prophylactic benefits of hydroxychloroquine, even as study after study showed it did not help prevent COVID cases or deaths. Rabois’s response to this was the line that Thiel’s FDA nominees had used: He blamed the bureaucracy of drug trials. “Randomized control trials are horrible ideas,” he tweeted. When Weinberg, the Roche executive, argued with him, Rabois shot back, “Obviously someone is jealous of my success.” Musk used his platform to minimize the severity of the disease, to tout hydroxychloroquine, and to call for a complete reopening of the economy—which he was particularly interested in because Tesla was facing a substantial order backlog.

He has an endgame, and what was becoming clear to me was that, within it, my doppelganger had an absolutely critical role to play. 7 MAGA’S PLUS-ONE When I was a kid, I learned more than I probably should have about the nitty-gritty of giving birth. My father, Michael Klein, was a family doctor and pediatrician, and, in addition to delivering hundreds of babies, he worked as a research scientist at McGill University, where he ran large randomized control trials across Montreal’s hospitals. The studies measured the impact of various kinds of interventions on health outcomes for mothers and babies—inductions, epidurals, forceps, episiotomies, cesareans. When data came in that was particularly striking, he could not keep the results to himself, which meant that I knew about postnatal incontinence and vaginal tearing before I hit puberty—and very much wished that I did not.

In a virtuous cycle, Shaw used his profits to fund further research. Newer strategies were built on previous findings and funded the next cycle of innovation, neatly paralleling the modern growth of information technologies. As Shaw explained, “We were taking profit and paying for experimentation. We were able to run randomized controlled trials, for example, in which we could compare two models or parameter values to see which one performed better in actual trading. Analyzing the results of live trading taught us things that couldn’t be learned by studying historical data. We were doing a lot of trading, and the data we accumulated during one round of trading was helping us to increase our returns in the next round.”

This culturally constructed biological reaction leads to higher rates of certain specific types of violent crimes in the Deep South. It’s a biological difference, but not a genetic difference. Chemically Inert but Biologically Active Placebos open a window on culture and biology. Most people have heard about placebos in the context of testing new medicines. In a randomized control trial, one randomly assigned group gets the drug under testing and the other group gets a sugar pill or other inert substance. Both groups are told they will get either the drug or the placebo (sugar pill) based on a coin flip, but they don’t know which. The common assumption is that this addresses any response bias, which might cause people to inaccurately report getting better or worse based on their opinions about the drug in question.

Practical and ethical considerations also come into play—some research designs can simply be impossible to execute, prohibitively expensive, or considered unethical—and the researcher must be aware of community as well as scientific standards concerning the ethical conduct of research. Basic Vocabulary Research designs can be divided into three types: experimental, quasi-experimental, and observational. For a design to be experimental, subjects must be randomly assigned to groups or categories. The classic experimental design is the randomized controlled trial used in medicine, in which subjects are randomly assigned to experimental and control groups, administered some treatment, and the outcomes collected for both groups. The controlled experiment is considered the strongest type of research design as far as drawing conclusions from the results of research (in fact, some refer to the results from experimental controlled trials as the gold standard of evidence), but it is not always possible or practical to conduct this type of research.

Any single-assignment language is easier to reason about, but that doesn’t make the programs easier to write, nor is there persuasive evidence that programs are easier to write. In fact, most comparative questions about languages, coding techniques, development methodologies, and software engineering in general, are appallingly unscientific. Here’s a quote from R. Bausell’s Snake Oil Science [Oxford University Press]: Carefully controlled research (such as randomized, controlled trials) involving numerical data has proved more dependable for showing us what works and what does not than has reliance upon expert opinions, experience, hunches, or the teachings of those we revere. Software is still a craft, rather like furniture making. There are Chippendales, there are craftsmen, and there are lesser practitioners.

Meehl’s work inspired Tversky and Kahneman’s discoveries on cognitive biases and Tetlock’s forecasting tournaments, and his conclusion about the superiority of statistical to intuitive judgment is now recognized as one of the most robust findings in the history of psychology.47 Like all good things, data are not a panacea, a silver bullet, a magic bullet, or a one-size-fits-all solution. All the money in the world could not pay for randomized controlled trials to settle every question that occurs to us. Human beings will always be in the loop to decide which data to gather and how to analyze and interpret them. The first attempts to quantify a concept are always crude, and even the best ones allow probabilistic rather than perfect understanding.
