Right, but unlike PG I don't think irrationality is an exclusivity of “losers”. Every human being is deeply irrational, everyone in their fashion and I don't buy the negative correlation between “success” and irrationality.

The issue is not just irrationality, it is toxic, hostile irrationality. Regardless of to what extent everyone is deeply irrational, only a minority are hostile. I have to agree, however, that some deeply hostile people have been successful, often by channeling the hostility of genuine losers.
