Ok, so I've got a few bob lying about and am considering a few things that I want to gather hard proof (one way or the other) on through actual scientific testing.

First things first, I want to know once and for all what the most important selectors are and how much all the various selectors we have contribute to our attraction of another person. The most important part of this would be proving whether or not looks are more or less important than anything else.

What other questions that need answers do people have? I'm writing a nice long list.
