Homo economicus

See this article. The above is the model most economists use to describe human economic activity. Given  the findings then basically these economists are at the intellectual level of chimps. No surprise there.

Per wikipedia the term means: "The concept in many economic theories portraying humans as consistently rational and narrowly self-interested agents who usually pursue their subjectively-defined ends optimally." Per the article:

"In our work we’ve tried to test some of the basic predictions made by the Homo economics model using some simple tools from behavioral economics applied across a diverse swath of human societies. Not only do we find that the Homo economicus predictions fail in every society (24 societies, multiple communities per society), but instructively, we find that it fails in different ways in different societies. Nevertheless, after our paper “In search of Homo economicus” in 2001 in the American Economic Review, we continued to search for him. Eventually, we did find him. He turned out to be a chimpanzee. The canonical predictions of the Homo economicus model have proved remarkably successful in predicting chimpanzee behavior in simple experiments. So, all theoretical work was not wasted, it was just applied to the wrong species."
