Success a bad teacher

Excerpt from an article by Joe Keohane. Original here.

And success, as Denrell revealed in an earlier study, is an especially bad teacher. In 2003 he published a paper arguing that when people study success stories exclusively — as many avid devourers of business self-help books do — they come away with a vastly oversimplified idea of what it takes to succeed. This is because success is what economists refer to as a “noisy signal.” It’s chancy, fickle, and composed of so many moving parts that any one is basically meaningless in the context of the real world. By studying what successful ventures have in common (persistence, for instance), people miss the invaluable lessons contained in the far more common experience of failure. They ignore the high likelihood that a company will flop — the base rate — and wind up wildly overestimating the chances of success.

To look at Denrell’s work is to realize the extent to which our judgment can be warped by our bias toward success, even when failure is statistically the default setting for human endeavor. We want to believe success is more probable than it is, that it’s the result of a process we can wrap our heads around. That’s why we’re drawn to prophets, especially the ones who get one big thing right. We want to believe that someone, somewhere can foresee surprising and disruptive change. It means that there is a method to the madness of not just business, but human existence, and that it’s perceptible if you look at it from the right angle. It’s why we take lucky rabbits’ feet into casinos instead of putting our money in a CD, why we quit steady jobs to start risky small businesses. On paper, these too may indeed resemble sucker bets placed by people with bad judgment. But cast in a certain light, they begin to look a lot like hope.
