Honestly, this isn't an excuse to swear in both of our two early morning articles. Researcher Brian Wu, author of the paper "Entrepreneurial Risk and Market Entry," tells BusinessWeek:

Entrepreneurs, like everybody else, hate uncontrollable risks, but on the other hand, they're overconfident in their own abilities — they think they can control their abilities in a random drawing of people. It's like the Lake Wobegon effect in assessing their position among peers. They think they're above the average.

Basically, entrepreneurs are irrationally arrogant. Really. They're not risk-takers, they just think they're better than you. And then they make enough money that they ARE better than you.

Hate your boss yet?
