Most psychology students would know about cultural differences and that you can not generalise. In fact, when writing a paper the first criticism is that generalisation should be made with caution because... and you list well pretty much every variability in the data. That said however, most psychology students are going to be working in the US and apply their knowledge to the US population. It was interesting however to read about the differences between students and the general population. I think one suggestion might be that rather than culture per se, it might be that some societies are more evolved which could explain many of the differences when comparing the west to the rest. Also, the focus of the paper seems to be on trying to find universal processes, and probably after give a just so evolutionary story for these processes. I do however think that looking at how we have evolved is not much different than looking at history. It might teach us of what was, but in very limited ways of what is. It is a good paper though. It highlights that psychologists are a bit lazy and do not do proper and thorough research but just create some theory and find the minimum data needed to support it.
