I agree. It was an essay on two of the big 5 personality traits: conscientiousness (conventional) and agreeableness (passivity). His thesis is that disagreeable conscientious people are responsible for "a disproportionate amount of trouble".

There's a couple problems with this though. First, these traits are sort of immutable - humans can't really change their personalities. Second, as you said, independent-mindedness can cause huge problems as well.
