The idea that we imitate too much. If you see somebody doing something that's inefficient or in the case of this arieli study we talked about bad like immoral, you inadvertently copy it. Yet, there's a wonderful bias that is a perhaps human unique bias. We have some evidence that you don't see it in primates or in dogs,. which is called over imitation. It sounds smarter, doesn’t it sound a little bit more evolved, as it were?"
