It helps, and that's why successful entrepreneurs are often pretty smart. If you're a smart person who's good at self-improvement, you can improve yourself Benjamin Franklin style (reading lots of business book summaries, trying to brainstorm how you can be more effective every evening, etc.), fix some brain bugs, and potentially make lots of money. My impression of successful entrepreneurs is that they are often self-improvement enthusiasts.

On the other hand, consider the "geek" versus "suit" stereotype. The "suit" is more determined and confident, but less intelligent. So it's not clear that intelligence is correlated with possessing fewer of these bugs in practice. I'm not sure why this is, although I have a few guesses.
