In this blog, I have repeatedly emphasized the fact that virtually all "stereotypes" are empirically true. If they weren't true, they would not be stereotypes in the first place. To my knowledge, all of the very, very few stereotypes that are not empirically true, for some reason, have to do with people's appearance. Hence, it is not true that beauty is in the eye of the beholder, and it is not true that beauty is only skin-deep.Another "stereotype" about physical appearance that is not empirically true is "you can't judge a book by its cover." In previous posts, I have explained that women can tell which men would make good fathers and which men would make bad fathers simply by looking at them. And people can tell who are altruistic and who are egoistic simply by looking at a 30-second video clip without sound.The article lets you try your hand at it as well. I did very well (10 of 13) on my definites, but once I had put someone into the indefinite category did no better than chance.
