Hayes of Carnegie Mellon University, identified more than five hundred works. When deliberate practice is engaged, as with those who are the best in their field, the 10yr/10000 hours rule pops up everywhere:Ī study of seventy-six composers from many historical periods looked at when they produced their first notable works or masterworks, designations that were based on the number of recordings available. Auditors become less skilled at certain types of evaluations.

More experienced doctors reliably score lower on tests of medical knowledge than do less experienced doctors general physicians also become less skilled over time at diagnosing heart sounds and X-rays. Occasionally people actually get worse with experience. 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. 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.

Auditors with years of experience were no better at detecting corporate fraud-a fairly important skill for an auditor-than were freshly trained rookies.

Via Talent Is Overrated: What Really Separates World-Class Performers from Everybody Else:Įxtensive 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. Most people may do something for 10000 hours (driving a car over the course of a lifetime) but never get anywhere near expert level (Formula One.) Most people plateau and some even get worse. It is not “just showing up” and, plain and simple, it’s not fun. It involves goal setting, quick feedback, and countless drills to improve skills with an eye on mastery. So is it true that 10000 hours makes you an expert?Īs Malcolm Gladwell discussed in his bestseller, “ Outliers“, to become an expert it takes 10000 hours (or approximately 10 years) of deliberate practice.īut deliberate practice is a specifically defined term.
