看了yale的《博弈论》，总结五点，如下：
1、不要选择劣势策略。（Don't play a strictly dominated strategy.）
2、耶鲁的学生很恶毒。（Yale students are evil.）即大多数人不会选择劣势策略。
3、理性选择导致次优的结果。（Rational choices lead to bad outcomes.）
4、换位思考。（Put yourself in other people's shoes.）
5、汝欲得之，必先知之。（It's a good idea to figure out what you want before you try and get what you want.）
