Research confirms what feels intuitive; entrepreneurs are an optimistic group, afflicted with the 'optimism bias,' a tendency to view the glass as half full backed by the belief that negative events are what happens to other people.
This is particularly true, one study found, of serial entrepreneurs, those bootstrapping men and women who we celebrate for persevering in the face of multiple failures. The more times you step up to bat, of course, the greater the likelihood that you'll hit a home run. But most of us aren't wired that way. We strike out, so we decide that maybe baseball isn't for us after all. It's a reasonable, rational response: we learn from our dismal performance, and are no longer as optimistic about our baseball abilities.
