One of the recurring characteristics of entrepreneurs, based on numerous biographies and case studies, is a driven self-confidence that may border, in some circles, as excessive or even narcissistic. Closer scrutiny, of course, shows there is no such thing as the “self-made” person, but entrepreneurship still is described often as a heroic, lone-wolf quest. Is it paradoxical to advocate for and even expect mentoring and “how to” entrepreneurship training to work? Wouldn’t “real” entrepreneurs leading promising startups succeed without the advice? A recent working paper describes an experiment that attempted to address this issue.
