Excerpt from Talent Is Overrated: What Really Separates World-Class Performers from Everybody Else by Geoffrey Colvin:
Extensive research in a wide range of fields shows that many people not only fail to become outstandingly good at what they do, no matter how many years they spend doing it, they frequently don’t even get any better than they were when they started.
Auditors with years of experience were no better at detecting corporate fraud—a fairly important skill for an auditor—than were freshly trained rookies. When it comes to judging personality disorders, which is one of the things we count on clinical psychologists to do, length of clinical experience told nothing about skill—“the correlations,” concluded some of the leading researchers, “are roughly zero.”
Surgeons were no better at predicting hospital stays after surgery than residents were. In field after field, when it came to centrally important skills—stockbrokers recommending stocks, parole officers predicting recidivism, college admissions officials judging applicants—people with lots of experience were no better at their jobs than those with very little experience.
