I would agree with you, and I think a lot of others would also. But that does not mean there is no truth in the generalization. We can see evidence of it every day all around us. Correct me if I am wrong, but maybe what you want to say is that what a non-jerk needs to do is analyze what aspects of the jerk\'s personality are attractive to women, and incorporate those into your behavior. For example, you mentioned confidence. Often nice guys don\'t have confidence but jerks do. I\'m not saying all nice guys don\'t have confidence, but I think it may often be the case.
