So there's the idea of 'depressive realism'. Basically, that depressed people may have more accurate judgements of the world than non-depressed people, since they're more willing to recognize the frequency of bad stuff.

I've always sort of wondered if there's a reverse effect - if the kind of person who can eagerly commit a big chunk of their life to a task with a 95%+ risk of failure is significantly less likely to be in touch with reality than others.
