Abstract

In the Frank (1988) model, a small increase in the number of cheaters will soon be reversed. It is not clear that this prediction holds for sociopathy. There are also many attractive evolutionary models that do not admit a small, stable proportion of cheaters. Hence, without definitive evidence about the character of early human society, we cannot conclude that sociopathy has an evolutionary origin.
