Fritz Heider and Marianne Simmel showed college students a brief animated film in which a few geometric shapes move around the screen, in and around a large rectangle, in randomly determined ways. The students were simply instructed to watch the movie and “write down what happened.” One of the thirty-four movie watchers described the film literally: “A large solid triangle is shown entering a rectangle. It enters and comes out of this rectangle, and each time the corner and one-half of one of the sides of the rectangle form an opening.” That guy was on his own. Nearly everyone else read more into it, telling a story about people, like this one:
A man has planned to meet a girl, and the girl comes along with another man. […]

好想认识 that guy！

谁能想到我开始看 The Social Animal 是因为我受不了游戏社区里的互骂了，中国人骂外国人，外国人骂中国人，而有着跨文化背景的我觉得两边都有被骂到，破防了​​

这个书里就讲到 Hunter-gatherer 时期一致对外是有利于生存的，因为外部社区通常都是来抢资源威胁生存的。现代人也总是会习惯性地把人划分成群体，也总是会觉得自己的群体比别人的更好。

我觉得理解两边的动机有助于我调整心态，不然总觉得大家都是讲不清道理的傻逼。
