One of the Basic Questions of Philosophy?

[David Sklansky]

If it isn't it, I think it probably should be. The question is: Is Cooker right when he posted on another thread

"Many people live under the mistaken belief that being correct is advantagous. This may or may not be the case. I think it is very possible, that certain incorrect views might have an advantage."

My answer is an in between one which I will get into later. What's yours?

PS We are not talking here about obvious occasional short term benefits of incorrect thoughts.
