In real life, however, you don't react to what someone did; you react only to what you think she did, and the gap between action and perception is bridged by the art of impression management. If life itself is but what you deem it, then why not focus your efforts on persuading others to believe that you are a virtuous and trustworthy cooperator?

Dividing into teams doesn't necessarily mean denigrating others. Studies of groupishness have generally found that groups increase in-group love far more than they increase out-group hostility.

To understand most important ideas in psychology, you need to understand how the mind is divided into parts that sometimes conflict. We assume that there is one person in each body, but in some ways we are each more like a committee whose members have been thrown together to do a job, but who often find themselves working at cross purposes.

Psychotherapy can help some people, especially people who are neurotic, who are always making problems for themselves. We are like a rider on an elephant. We can steer the elephant, and if he's not busy, he'll go where we want, but if he has other desires, he'll go where he wants. They need to get a better relationship between the rider and the elephant. In part, you get it just from watching yourself stumble around in life, make mistakes, then read a little psychology and stop blaming yourself. Realize that I am flawed. I am complicated. I am divided, and I'm doing the best I can.

I think moral philosophy is speculation on how we ought to live together done by people who have very little clue how people work. So I think most moral philosophy is disconnected from the species that we happen to be. In fact, they like it that way. Many moral philosophers insist that morality grows out of our rationality, that it applies to any rational being anywhere in the universe, and that it is not based on contingent or coincidental facts about our evolution.
