alt Hacker NewsPessimists are just as often wrong too! Clearly the person you're replying to is an "optimist". :)
To be clear, I don't think there's a strong correlation between being rich and being a pessimist/optimist.
And to your original point, being right cannot possibly be biased towards optimism or pessimism. Any apparent correlation is more of a reflection on what everyone else thinks... and they are wrong! Cheers to being right!
I remember reading that slightly depressed people tend to have a more accurate world view.
Perhaps there is something to the saying ignorance is bliss.
