“My research team at Duke and Harvard surveyed 652 U.S.-born chief executive officers and heads of product engineering at 502 technology companies. We found that they tended to be highly educated: 92 percent held bachelor’s degrees, and 47 percent held higher degrees. But only 37 percent held degrees in engineering or computer technology, and just two percent held them in mathematics. The rest have degrees in fields as diverse as business, accounting, finance, health care, and arts and the humanities.

Gaining a degree made a big difference in the sales and employment of the company that a founder started. But the field that the degree was in and the school that it was obtained from were not a significant factor.

Over the past year, I have interviewed the founders of more than 200 Silicon Valley start-ups. The most common traits I have observed are a passion to change the world and the confidence to defy the odds and succeed.
