The Buzz Blog has a very interesting breakdown and analysis of GRE scores correlated to the intended majors. Physics majors tend to do quite well in such test, especially in quantitative reasoning (not surprising, really).
What I find more fascinating is which majors did poorly in these categories. Political science majors did only half as well as physics majors in quantitative reasoning (again, not surprising), but they aren't even listed in the top 7 for the others! Are these the same people who will be part of our political system? Scary!
I've always believed that you don't elect someone simply because that person shares your point of view on certain things. You elect someone who has the ability to THINK things through and know how to see answers to those he/she doesn't know about. If you don't, you end up with morons such as Todd Akin who bastardize science to his benefit. How many times have we seen politicians unable to either look up some simple information, or think things analytically? People in politics WILL encounter unexpected, complex, and difficult issues. You want someone who has the ability to think rationally, not just someone who happens to agree with you on such-and-such. If not, you'll be lied to.
