 The argument they make is that by treating everything as a kind of "economy" they make a particular vision of the way an economy works seem more natural.Thus, they suggest, rational choice is as much ideological as it is scientific, which does not in and of itself negate its scientific utility.An evolutionary psychology perspective is that many of the seeming contradictions and biases regarding rational choice can be explained as being rational in the context of maximizing biological fitness in the ancestral environment but not necessarily in the current one.
