When people change their irrational beliefs to undogmatic flexible preferences, they become less disturbed.
Rational beliefs bring us closer to getting good results in the real world.
There's no evidence whatsoever that men are more rational than women or that men are more willing to surrender their irrational beliefs. Both sexes seem to be equally irrational.
Beginning in the 1960s, many studies showed that people who hold what we call irrational beliefs are significantly more disturbed than when they don't hold them, and the more strongly they hold them, the more disturbed they tend to be.
