It should be no different this time, even though the Great R. is a tempered version of the Great D. Americans now know that housing prices don’t always go up, and that they can in fact go down by 30–50% in a few short years. Because of this experience, private mortgage lenders will demand extraordinary down payments, impeccable credit histories, and significantly higher yields than what markets grew used to over the past several decades. Could an unbiased observer truly believe that housing starts of two million or even one million per year could be generated under the wing of the private market? In front of Treasury Secretary Geithner and the assembled audience, I said that was impractical. Let me amend that to “ludicrous.” Policymakers not only have to consider the future “flows” of new mortgage originations, but the existing “stock” of mortgages already created.

Farr’s original report had looked only at the level of entire districts, but Snow now divided the original data into subdistricts organized by water supplier. Twelve of them relied on water from S&V, while three drank Lambeth water exclusively. And indeed, the disparity between the two groups in terms of cholera deaths was pronounced: roughly 1 in 100 died in the S&V subdistricts, while not a single person had died of cholera among the 14,632 Lambeth drinkers. An unbiased observer might have been persuaded by those numbers, but Snow realized his audience required more, primarily because the subdistricts served by Lambeth alone were relatively well-to-do suburbs, in contrast to the smog-bound industrial zones that S&V serviced. Once the miasmatists had a look at the different neighborhoods, Snow knew his case would dissolve in a heartbeat. And so the experiment would rise and fall on the sixteen remaining subdistricts that received both S&V and Lambeth water.

It would be only fair here to point out that I am not exactly an unbiased observer. For one thing, Sean, like just about everyone else I cite in the book, is a friend. We met through working on these things together but since have kept in touch and share emails about what we’re working on and are just generally nice to each other. And the same goes for almost all the other people I cite and criticize. Moreover, the reason we were working together is that I too did my time in the Semantic Web salt mines.

Hagelberg and colleagues were forced to publish a retraction, and she herself now refers to the unfortunate affair as her ‘infamous mistake.’ By 2001, the evidence for recombination looked muddy, to say the least. The two major studies had both been discredited, and although the authors of both papers maintained that the rest of their data still raised doubts, that was only to be expected; they had to defend their tattered reputations. For an unbiased observer, it seemed that recombination had been disproved. Then in 2002, a fresh challenge emerged. Marianne Schwartz and John Vissing, at Copenhagen University Hospital, reported that one of their patients, a 28-year-old man suffering from a mitochondrial disorder, had actually in- 250 Human Pre-History and the Nature of Gender herited some mitochondrial DNA from his father, and so had a mixture of both maternal and paternal DNA—the dreaded heteroplasmy.

A fourth possibility, almost too obvious to need mentioning, is that Jesus was honestly mistaken. Plenty of people are. In any case, as I said, there is no good historical evidence that he ever thought he was divine. The fact that something is written down is persuasive to people not used to asking questions like: ‘Who wrote it, and when?’ ‘How did they know what to write?’ ‘Did they, in their time, really mean what we, in our time, understand them to be saying?’ ‘Were they unbiased observers, or did they have an agenda that coloured their writing?’ Ever since the nineteenth century, scholarly theologians have made an overwhelming case that the gospels are not reliable accounts of what happened in the history of the real world. All were written long after the death of Jesus, and also after the epistles of Paul, which mention almost none of the alleged facts of Jesus’ life. All were then copied and recopied, through many different ‘Chinese Whispers generations’ (see Chapter 5) by fallible scribes who, in any case, had their own religious agendas.

Nevertheless, Hoyle continued to defend his model:‘I think that it is fair to say that the theory has demonstrated strong survival qualities, which is what one should properly look for in a theory. There is a close parallel between theory and observation on the one hand, and mutations and natural selection on the other. Theory supplies the mutations, observation provides the natural selection. Theories are never proved right. The best they can do is to survive.’ But the Steady State model and its Quasi-Steady State reincarnation were barely surviving. Any unbiased observer could see that they were on the brink of extinction, whereas the Big Bang model was not only surviving, but thriving. The universe simply made more sense in the context of the Big Bang model. For example, in 1823, when scientists assumed that the universe was infinite and eternal, the German astronomer Wilhelm Olbers wondered why the night sky was not ablaze with starlight. He reasoned that an infinite universe would contain an infinite number of stars, and if the universe was infinitely old then this would have allowed an infinite amount of time for the starlight to have reached us.

Should you be using long-term forecasts for equity risk premia when the next equity risk premium could be negative? We use tactical asset allocation models to manage a portion of our capital and help our research process. These models help in two ways. First, they provide us with an independent yardstick, which we try to outperform. Second, we think of our tactical asset allocation model as an unbiased observer of the markets, which we use to give us some sense of the market’s momentum. They are price-based, momentum-driven models that have been running since about 2005, and have produced consistently positive results. Even our longer term model broke even in 2008, and it is only allowed to be long assets because in the long term you want to earn risk premium. After being down about 8 percent by the fall of 2008, it switched heavily into U.S. fixed income and recouped its losses by year-end.

The court reasoned that because Filburn grew wheat to feed his livestock, he would therefore buy less wheat from other farmers. If many farmers were to do this, it would significantly lower the price of wheat. This, in turn, would have an effect on commerce in wheat, some of which crosses state borders. Therefore, by fining Filburn for growing too much wheat, the federal government was simply exercising its constitutional power to regulate interstate commerce. It is hard to believe that any unbiased observer competent in the English language would read the phrase ‘regulate commerce [ ... ] among the several states’ in this way. Here is the unofficial but more truthful account of events: At the beginning of his presidency in the early 1930s, Franklin Delano Roosevelt’s New Deal programs were repeatedly and decisively struck down for exceeding the powers granted by the Constitution.42 President Roosevelt sought to circumvent these decisions by proposing the Judicial Procedures Reform Bill of 1937, which would have given him the power to appoint six new justices to the Supreme Court, bringing the total to fifteen.

THOMAS HAWKES TANNER, A Manual of Clinical Medicine and Physical Diagnosis, 1869 Chapter Fourteen THE MYTHOLOGY OF OBESITY A colleague once defined an academic discipline as a group of scholars who had agreed not to ask certain embarrassing questions about key assumptions. MARK NATHAN COHEN, Health and the Rise of Civilization, 1989 CRITICAL TO THE SUCCESS OF any scientific enterprise is the ability to make accurate and unbiased observations. “To have our first idea of things, we must see those things,” is how Claude Bernard explained this in 1865; “to have an idea about a natural phenomenon, we must, first of all, observe it…. All human knowledge is limited to working back from observed effects to their cause.” But if the initial observations are incorrect or incomplete, then we will distort what it is we’re trying to explain.

Schreiber setting aside a contract and the scientific calculations of quantities executed and to be executed by engineers and adopting those guessed at by the company’s men in riding over the line – occasionally appealing to Trutch who sat behind looking wise and blinking like a Centennary owl – confirming by a nod everything that Schreiber did. This was the end of the first act of the drama of corruption openly played.” Although Marcus Smith’s witness cannot be taken as gospel – he was far too suspicious of too many people to be considered a fair or unbiased observer – it is quite clear that, for one reason or another, the government engineers did not hold Andrew Onderdonk to the letter or even the spirit of his contract and that they allowed a good deal of shoddy work to go unremarked. (It is possible that Onderdonk’s vigorous lobbying in Ottawa persuaded the government to wink at some of the shortcuts he subsequently took.) Van Horne, when he travelled the line in August, made no public remark other than that he was “agreeably surprised to find the character of the country so favorable generally for railway construction, and is satisfied that the line will be completed inside of 16 months.”

We boxed the last of them up at Kapa and Durb,” (he used the Zulunder terms for Capetown and Durban) “and drove them into the sea.” Literally, added Ribera to himself. The last remnants of White Africa were physically pushed from the wharves and sunny beaches into the ocean. The Zulunders had succeeded in exterminating the Whites, and thought they succeeded in obliterating the Afrikaner culture from the continent. Of course they had been wrong. The Afrikaners had left a lasting mark, obvious to any unbiased observer; the very name Zulunder, which the present Africans cherished fanatically, was in part a corruption of English. “By the sixtieth day, we could say that not a single White lived on the continent. As far as we know, only one small group evaded vengeance. Some of the highest-ranking Afrikaner officials, maybe even the Prime Minister, commandeered two luxury vessels, the SR Hendrik Verwoerd and the Nation.

At a meeting of the Newcastle Literary and Philosophical Society on 5 December 1815, at which both Clanny’s bellows lamp and Stephenson’s conical lamp were examined (’it resembles a wine decanter’, remarked the Newcastle Chronicle jovially), the questions of priority and pirating were first raised. The Newcastle Society showed its admirable objectivity by presenting examples of the true gauze lamp, as used by Buddle at Walls End, at its meeting of 6 February 1816. It was immediately clear to unbiased observers that the Stephenson and the Davy were very different instruments. But nothing could prevent the major public row now brewing, with letters to the newspapers, polemical pamphlets, and wide controversial comment in the journals. Not all of this was favourable to Davy, and there was a clear evidence of a North-South split as sides were taken. Furious pamphlets were written against him by a Sunderland lawyer and journalist, J.H.

Systematic error, if present, could be due to an imperfection in the scale, always causing the observed weight to be lower than the true weight.

This national process of soul-searching chimes in with a growing sense of unease about where English society is headed. A recent spate of stabbings and shootings coupled with the growing gang culture in many English cities, plus the continuing divisiveness of the wars in the Middle East and the fallout from the 7/7 tube bombings (committed by British-born extremists) all hint at the disaffection and disillusionment felt by many English communities. Even the most unbiased observer would have to admit that there’s something slightly awry in a country that has more CCTV and speed cameras than anywhere else in Europe and where the nation’s kids have been dubbed ‘the unhappiest in the Western World’ according to a recent Unicef poll. It’s perhaps unsurprising that record numbers of people are giving Blighty the boot in favour of pastures new. But others are opting to stay in England and go back to the land, quitting the cities for slower, greener, more sustainable lives in the countryside.
