    The Superstar Effect

    Cal Newport has a guest post on Tim Ferriss' blog about the Superstar Effect.

    When Michael, a student from Paradise Valley, Arizona, applied to Stanford, his G.P.A. put him in the bottom 10% of accepted students. His SAT scores fell similarly short. "Standardized testing isn't my strong point," he told me. Perhaps more surprising, Michael avoided the crushing course load that diminishes the will of so many college hopefuls, instead taking only a single AP course during the dreaded junior year. He kept his extracurricular schedule equally clean — joining no clubs or sports and dedicating his attention to no more than one outside project at any given time.

    Michael's rejection of the no pain, no gain ethos surrounding American college admissions is perhaps best summarized by his habit of ending each school day with a 1 – 2 hour hike to the summit of nearby Camelback Mountain. While his peers worked slavishly at their killer schedules, Michael took in the view, using his ritual as a time to "chill out and relax."

    Despite this heretical behavior, Michael was still accepted at Stanford. To understand why, I will turn your attention to a little-known economics theory that changes the way we think about impressiveness.

    College admissions is an interesting game. I was a finalist for the Flinn scholarship, a generous program that aims to keep talented students in Arizona rather than losing them to Ivy League schools and coastal cities. I did not receive the scholarship, but for being a finalist I was still able to attend college in Arizona for free. Every year the three state universities compete with one another to try and attract Flinn scholars to their schools, so I was selected to help woo potential students at special recruiting events. I was able to see the resumes of the Flinn scholars, and much like applicants to Ivy League schools, it is not unusual for top students to have have more extra curricular activities listed than there are actually time for in a week.

    The status competition in college admissions has progressed to the point where you need more than a 4.0 GPA on a scale of 0-4, and 5-10 extracurriculars. It is an arms race. The best way to win an arms race is to change the rules. As someone said in another context, "surprise is an event that occurs in the mind of an enemy commander", or a rival applicant. Michael Silverman achieved tactical surprise.

    It is kind of funny that Silverman used a hike up Camelback mountain to relax. It is usually still pretty hot when school gets out in Paradise Valley. Most people who hike Camelback do it at 6 AM, not 3 PM. I suppose it could be relaxing if you were the only one up there.

    In a 1981 paper published in the American Economics Review, the economist Sherwin Rosen worked through the mathematics that explains why superstars, like Pavarotti, reap so many more rewards than peers who are only slightly less talented. He called the phenomenon, “The Superstar Effect.”

    Though the details of Rosen's formulas are complex, the intuition is simple: Imagine a million opera fans who each have $10 to spend on an opera album. They're trying to decide whether to buy an album by Florez or Pavarotti. Rosen's theory predicts that the bulk of the consumers will purchase the Pavarotti album, thinking, roughly: "although both singers are great, Pavarotti is the best, and if I can only get one album I might as well get the best one available." The result is that the vast majority of the $10 million goes to Pavarotti, even though his talent advantage over Florez is small.

    Once identified, The Superstar Effect turned up in a variety of unexpected settings, from the sales of books to CEO salaries. It was found to apply even in settings that have nothing to do with financial transactions. In a particularly compelling example, a researcher named Paul Atwell, publishing in the journal Sociology of Education in 2001,studied the Superstar Effect for high school valedictorians.

    Atwell imagined two students both with 700s on their various SAT tests. The first student was the valedictorian and the second student was ranked number five in the class. Rationally speaking, these two students are near identical — the difference in G.P.A. between the number one and number five rank is vanishingly small. But using statistics from Dartmouth College, Atwell showed that the valedictorian has a 75% of acceptance at this Ivy League institution while the near identical fifth-ranked student has only a 25% chance.

    In other words, in many fields, it pays disproportionately well to be not just very good, but the best.

    The key here is that it is easier to be the best if there isn't much competition. The GPA and extracurriculars competition is pretty well known and stagnant, so the race goes to those with motivated and wealthy parents for the most part. However, if you can find an uncontested field, the bar is lower. Newport says:

    Notice that nothing about Michael's rise to stardom required a rare natural talent or overwhelming work load. His projects required, on average, less daily time investment than participating in a varsity sport. Yet, he was the best at what he did among all applicants to Stanford, and the resulting Superstar Effect earned him a disproportionate reward.

    That Silverman was the best is something I totally agree with, but I'm not sure that I actually agree that this achievement did not require rare natural talent.  The ridiculous workload for the Ivy-bound is the mark of a mature competition among near equals. Easy work can be the result of either a light field, unusual talent, or both. Carl Lewis only spent 8 hours a week training for the 1984 Olympics. Most Olympians would be aghast, or jealous at that. Silverman probably has an unusual level of whatever it is that allows you to get things done. Given his unremarkable GPA and SAT, it is probably not conscientiousness or drive, but something else that you can find in successful businessmen.

    This kind of achievement is actually not unheard of, but it is primarily the domain of Eagle Scouts [who are mostly LDS now]. 10 years ago I would have been pretty down on this kind of thing as opposed to purely academic achievements. Why wouldn't you just want to reward the smartest? Now that I have been out in the world, I can appreciate the business of business, and respect the kind of skills that a top salesman or executive possesses. The kinds of things generically labeled "leadership" activities by university admissions departments really are an important part of keeping the wheels from falling off our society. Oftentimes, those who are best at these things are not the smartest, but rather just smart enough to not get in the way. Being too smart can actually be a detriment.

    Japanese Deflation

    Reading the WSJ article on deflation linked below, I had to wonder:

    But Japan's experience has looked nothing like this. Rather than being deep, destructive and concentrated in a few years, deflation has been a surprisingly mild, drawn-out affair. Consumer prices have been falling in Japan for 15 years, but never by more than 2% in any single year. Japan's deflation has been a morass, but not the destructive downward spiral many economists predicted. Why? And what does it portend for the rest of the world today?

    The Japanese economy is basically stable, with a shrinking, aging population, and a tradition of continuous improvement in manufacturing that is world-famous. Why wouldn't prices keep going down in this situation? Consumer demand should be shrinking as the population shrinks, and the price of manufacturing just about anything should be going down as well. Is this too obvious?

    Deflation: So What?

    Jerry Pournelle has a good bit on deflationary spirals today.

    Deflation

    The new fear is deflation. There's also the plea that we don't really understand deflation. Roosevelt didn't understand it either, although the New Deal took a number of measures to combat it, including requiring farmers to pour out milk and slaughter little pigs in the hopes of driving prices higher (see Amity Schlaes The Forgotten Man for a lot more on that.) What the New Deal did understand was that deflation brought about a nasty spiral, and the Great Depression hung on and on and on. Japan, having been the model for economic growth -- I suppose not many remember when Japanese visitors drove a real estate boom in Hawaii -- suddenly went bust and a deflationary period came with a long period of slow economic growth. People talk about the lost decade. Deflation, slow economic growth, and rising unemployment all went together.

    ...

    As an example; for a number of years we had the North American Free Trade agreement. Ross Perot worried that the "giant sucking sound" you heard was the export of American jobs to Mexico. Indeed, a great number of maquiladores, factories just across the border in Mexico, sprang up, and a great number of jobs were moved to Mexico. Most of those were light manufacturing, labor intensive work making consumer goods. The result was lower prices of such consumer goods. That brought down prices in the US, and one supposes that it cost some US jobs, but the times were pretty good. Most of the maquiladores were built with US capital and much of the profit returned to US owned companies, while at the same time the presence of good jobs in Mexico lightened the pressure on the US borders.

    Then came Wal-Mart (and others, but I particularly remember Wal-Mart) which put pressure on its suppliers to bring prices even lower. The way to do that was to export the jobs from Mexico to China while at the same time insisting on unrestricted free trade with China. (The Chinese began by demanding "most favored nation" status, meaning that they'd get as good a tariff deal as Mexico.) Chinese labor was cheaper than labor in the maquiladores. The result was the ruin of many of the maquiladores. The jobs were exported to China. I don't know if the reciprocal free trade with China brought about more US export, but it doesn't seem to have. I know that in the case of intellectual property, there tended to be the export of a few US copies followed by the widespread availability of the property -- books, movies, software, music -- in Chinese editions that didn't pay any royalties back to the US. Perhaps there were compensating sales I don't know about. Mostly, though, jobs flowed to China.

    Over time a good part of the US economy shifted from making consumer goods to opening containers of consumer goods made in China. The Mexican economy was hit even harder as the maquiladores began to shrink, then close.

    The result was lower prices of consumer goods, but also unemployment in the US and Mexico.

    No one seems to recognize this as a self-inflicted deflationary spiral, but I do wonder if we didn't do exactly that to ourselves? And meanwhile we continue to impose all kinds of regulations -- many very good I am sure -- on American businesses. Minimum wages, safety regulations, work rules, retirement packages, health care -- all of which raise the price of American labor and make it far more profitable to export a job than to create one.

    I have for a long time thought that imposing a 10% across the board tariff on imported goods -- all of them -- would make considerable sense. It might even slow down the self-inflicted deflationary spiral of lower cost goods and rising unemployment. And note that unemployment isn't free, as witness the continuing extension of unemployment benefits. Money paid as unemployment compensation is extracted from the still-profitable part of the economy, and of course unemployment compensation taxes make US labor more expensive, and thus encourages job export: job export brings lower prices and more unemployment.

    I continue to be puzzled by the fear of deflation. I am not enough of an economist to know the economic arguments, although the historical analogy with the Great Depression is clear enough. I just cannot help but protest, the long period of deflation in Japan has not been the end of the world. I am not Japanese, nor do I live there, but I still fail to see that life has suddenly become horrible for the Japanese. The fear and  the observable results do not match.

    I do understand that the econometric models predict that the economy will suffer in this situation. Like Pournelle, I want to know whether success has been properly defined in those models?

    Modern Moral Reasoning

    A whole series of things I read recently got me thinking of the subject of moral reasoning. Moral philosophy is not a course I have yet taken in my M.A. studies, but I am already solidly in the broadly Aristotelian tradition of virtue ethics that constitutes one of the primary threads of Western moral reasoning. The key question here is "what must I do in order to become good?"

    Another major thread is broadly Kantian, and is probably the dominant, although not necessarily preponderant thread in Western societies. The theme of this kind of moral reasoning is autonomy, the idea that our human dignity requires that we be self-legislating in moral matters.

    Elizabeth Warren, the author of the Two Income Trap, was nominated to head the new Consumer Financial Protection Bureau. This greatly concerned Tyler Cowen, who worried that limitations on credit, even clearly risky credit, undermine autonomy.

    Steve Sailer points out that the law that authorizes this new agency specifically limits its authority to impose usury regulation. So thankfully, the right to engage in usury remains uninfringed.

    This is a good example of why autonomy is a poor basis for action. Autonomy does indeed require that we allow people to enter into any damn fool terms they want to, provided they understand them [which is is pretty much never in the case of the payday loan places that occasioned this]. However, when this kind of thing comes up for a vote, you find that a majority of the citizenry regard this as an obviously bad idea, as when Arizona recently restricted the ability of payday loan businesses to operate

    A recent paper about WEIRD people [Western, Educated, Industrialized, Rich, Democratic] illustrates the disconnect between Cowen et al. and the citizenry. 

    Research in moral psychology indicates that typical Western subjects rely principally on justice- and harm/care-based principles in judging morality. However, recent work indicates that non-Western adults and Western religious conservatives rely on a wider range of moral principles than these two dimensions of morality (Baek 2002, Haidt & Graham 2007, Haidt, Koller, & Dias 1993, e.g., Miller & Bersoff 1992). Shweder, Much, Mahapatra, and Park (1997) proposed that in addition to a dominant justice-based morality, which they termed an ethic of autonomy, there are two other ethics that are commonly found outside the West: an ethic of community, in which morality derives from the fulfillment of interpersonal obligations that are tied to an individual’s role within the social order, and an ethic of divinity in which people are perceived to be bearers of something holy or god-like, and have moral obligations to not act in ways that are degrading to or incommensurate with that holiness.

    Even among Westerners, the kinds of moral reasoning that look to obligations beyond the self are not dead, merely dormant. Metahistory suggests to us that the modern age is ending, and that we will see a return to social dominance of the commonsensical opinion that making high-interest loans to the obviously irresponsible harms the common weal.

    CrossFit Adidas Commercial

    Steve Hsu said something in his post about the CrossFit games that surprised me a little at first, but after I thought about it for a bit I think he has a point:

    The sport is kind of wacky -- kind of like the early days of triathlon, I guess. The competitors are wannabes in each of the core movements: weak Olympic lifters, clumsy gymnasts, slow sprinters, etc. But they have an all-around versatility. 

    DJ Wickham

    Compare one of the best competitors at the 2010 CrossFit games, DJ Wickham, with the 2008 Beijing super heavyweight gold medalist, Matthias Steiner.

    Matthias Steiner

    Wickham just isn't in the same league as Steiner [or weightclass]. But, I bet Wickham runs faster.
