I'm intrigued by the concept of "emotional intelligence", which is kind of a measure of your ability to get along with other people. I found a pretty interesting test here. It's even "scientifically validated", whatever that means (this assumes that social studies are actually "scientific") The trick here is that you have to answer the questions honestly, and that's kind of hard to answer questions about yourself objectively.
Anyway, I scored right in the middle, which I guess means I'm not the most sensitive guy, but I'm also not a total robot either. But then, who needs a 106 question test to tell you that about yourself?
