In 1979, in the third, now annual, Baseball Abstract, James wrote, “a hitter should be measured by his success in that which he is trying to do, and that which he is trying to do is create runs. It is startling, when you think about it, how much confusion there is about this. I find it remarkable that, in listing offenses, the league will list first—meaning best—not the team which scored the most runs, but the team with the highest batting average. It should be obvious that the purpose of an offense is not to compile a high batting average.” Because it was not obvious, at least to the people who ran baseball, James smelled a huge opportunity. How did runs score? “We can’t directly see how many runs each player creates,” he wrote, “but we can see how many runs each team creates.” He set out to build a model to predict how many runs a team would score, given its number of walks, hits, stolen bases, etc. He’d dig out the numbers for, say, the 1975 Red Sox.

As Jason Giambi steps into the batter’s box, the TV cameras flash back and forth between him and his younger brother in left field. The announcers wish to draw out a few comparisons. Poor Jeremy. He still needed a baseball genius to divine his true worth but any moron could see the value of his older brother, at the plate. In all of baseball for the past few years there has been only one batter more useful to an offense: Barry Bonds. Giambi has all the crude offensive attributes—home runs, high batting average, a perennially high number of RBIs. He also has the subtler attributes. When he’s in the lineup, for instance, the opposing pitcher is forced to throw a lot more pitches than when he isn’t. The more pitches the opposing starting pitcher throws, the earlier he’ll be relieved. Relief pitchers aren’t starting pitchers for a reason: they aren’t as good. When a team wades into the opponent’s bullpen in the first game of a series, it feasts, in games two and three, on pitching that is not merely inferior but exhausted.

Startup CEO: A Field Guide to Scaling Up Your Business, + Website by Matt Blumberg

activist fund / activist shareholder / activist investor, airport security, Albert Einstein, bank run, Ben Horowitz, Broken windows theory, crowdsourcing, deskilling, fear of failure, high batting average, high net worth, hiring and firing, Inbox Zero, James Hargreaves, Jeff Bezos, job satisfaction, Kickstarter, knowledge economy, knowledge worker, Lean Startup, Mark Zuckerberg, minimum viable product, pattern recognition, performance metric, pets.com, rolodex, Rubik’s Cube, shareholder value, Silicon Valley, Skype

At each step along the way, we labored to align our resources with our market opportunity and financial resources. It was hard and we made mistakes aplenty but using a baseball metaphor, we managed to “hit with a high batting average.” We were able to successfully navigate them by following many of the themes that Matt outlines below and our efforts were rewarded when we sold Quickoffice to Google in 2012. The alignment of your business strategy with your resources is really tough and you will rarely know you have done it well or not so well, until after the fact. I believe your goal is to achieve that “high batting average” so your business will stay healthy enough to continue forward successfully. That’s the lesson I hope you take away from this section. Alan Masarek, Former CEO, Quickoffice BUDGETING IN A CONTEXT OF UNCERTAINTY A lack of certainty around revenue forecasts and budgetary needs should have one certain outcome: managing expenses on the assumption of worst-case scenario—or something close to it.

Stealing Fire: How Silicon Valley, the Navy SEALs, and Maverick Scientists Are Revolutionizing the Way We Live and Work by Steven Kotler, Jamie Wheal

Recent research conducted on Burning Man sheds some light on that “something.” In 2015, a team of scientists led by Oxford neuropsychologist Molly Crockett7 joined forces with the Black Rock City Census to take a closer look at the festival’s power. In their study, 75 percent of attendees reported having a transformative experience at the event, while 85 percent of those reported that the benefits persisted for weeks and months afterward. That’s an incredibly high batting average: Three out of four people who attend the event are meaningfully changed by it. And this doesn’t just happen by accident. Wandering out into the middle of that intentional chaos at 2 a.m., surrounded by fire-spewing dinosaurs, giant neon-lit pirate ships, and the throbbing beats of galactic hip-hop, you’re ripped away from all familiar reference points, totally unstuck in time, and well beyond normal awareness.

Even for more ephemeral skills, like outstanding positional play in professional basketball, that are harder to measure directly but still help the team win, we have almost one hundred NBA games each season that we can watch to observe a player’s effect on his team and on the outcome.13 At first, it seems that an accomplishment like beating the S&P 500 for the year is a pretty good equivalent of a batting average for fund managers—and indeed fund managers with long streaks do tend to beat the S&P 500 more often than average, just like baseball players with high batting averages. By this measure, however, in a forty-year career a fund manager will get only forty “at-bats” total—simply not enough data to estimate the true value with any confidence.14 THE MATTHEW EFFECT And finance is in many respects an easy case—because the existence of indices like the S&P 500 at least provide agreed-upon benchmarks against which an individual investor’s performance can be measured.

Every Patient Tells a Story by Lisa Sanders

And, as it turns out, it is one of the most reliable as well. Indeed, the great majority of medical diagnoses—anywhere from 70 to 90 percent—are made on the basis of the patient’s story alone. Although this is well established, far too often neither the doctor nor the patient seems to appreciate the importance of what the patient has to say in the making of a diagnosis. And yet this is crucial information. None of our high-tech tests has such a high batting average. Neither does the physical exam. Nor is there any other way to obtain this information. Talking to the patient more often than not provides the essential clues to making a diagnosis. Moreover, what we learn from this simple interview frequently plays an important role in the patient’s health even after the diagnosis is made. When you go to see a doctor, any doctor, there is a very good chance that she will ask you what brought you in that day.

Team of Teams: New Rules of Engagement for a Complex World by General Stanley McChrystal, Tantum Collins, David Silverman, Chris Fussell

Their ability to specialize in their own domains necessitated ignorance of the process at large—for operators, time spent learning about the “black box” of intelligence was a distraction that took them away from their proper duties. But this limited definition of efficiency meant that they passed on information that was often less useful than it should have been, late, or lacking context. Had each of our teams been an individual at BUD/S, he would have gotten booted in week one. They took pride in their own team’s performance, like the prima donna slugger who touts his high batting average as his team consistently loses. Instinctively, the silos of our organization looked inward, where they could see metrics of success and failure. The habit of constraining information derives in part from modern security concerns, but also from the inured preference for clearly defined, mechanistic processes—whether factory floors or corporate org charts—in which people need to know only their own piece of the puzzle to do their job.

In fact, the top 1 percent of households have more wealth than the entire bottom 90 percent combined. Economic inequality has led to striking changes in our society. ♦ In America's new winner-take-all society there is infinitely more to gain, and to lose, when it comes to getting into the right college, getting the right job, becoming a "hot" reporter, showing good earnings on Wall Street, having a high batting average, or otherwise becoming a star achiever. ♦ Higher inequality has led to more divisions between Americans and weakened the social fabric—undermining the notion that we're all "in it together" and bound by the same rules. ♦ Inequality is also reshaping our politics as wealthier Americans get more adept at turning money into influence—twisting rules to their benefit and escaping punishment when they break the rules

His intuition for a trend change in the currency or bond markets is unmatched, as is his ability to withstand short-term movements against him. Interestingly, Nick works alone and visits over 100 companies per year. Aside from their trading acumen, Stan and Nick are the class acts of the hedge fund business. Their word is their bond, they eschew publicity, and they are dedicated family men. George Soros, on the other hand, is much more volatile than Stan and Nick. He is the opposite of Warren Buffett. Buffett has a high batting average. George has a terrible batting average—it’s below 50 percent and possibly even below 30 percent—but when he wins it’s a grand slam. He’s like Babe Ruth in that respect. George used to say, “If you’re right in a position, you can never be big enough.” Having worked with both Soros and Jim Rogers, what differences did you note between former partners? Rogers is an analyst while Soros is a trader.

A good baseball projection system must accomplish three basic tasks: Account for the context of a player’s statistics Separate out skill from luck Understand how a player’s performance evolves as he ages—what is known as the aging curve The first task is relatively easy. Baseball, uniquely among the major American sports, has always been played on fields with nonstandard dimensions. It’s much easier to put up a high batting average in snug and boxy Fenway Park, whose contours are shaped by compact New England street grids, than in the cavernous environs of Dodger Stadium, which is surrounded by a moat of parking lot. By observing how players perform both at home and on the road, we can develop “park factors” to account for the degree of difficulty that a player faces. (For example, Fred Lynn, an MVP with the Red Sox during the 1970s, hit .347 over the course of his career at Fenway Park but just .264 at every other stadium.)
