Now I do not know what the scores are for Canada but according to the GRE statistics reported here, it appears that in two out of the three categories political scientists have superior GRE scores relative to their cousins in economics. But then this should hardly be surprising given that political scientists receive better training in their undergrad in verbal and analytical writing skills than their counterparts in economics. And, as it turns out, economists receive superior training in math in their undergrad education than their political science counterparts.
Thus, each scores better in what they were most heavily trained. Wow who would have thought education works?
This just in: those receiving training in plumbing are better at plumbing than your average DIY weekend warrior. I guess plumbers are smarter than the rest of us.
