Looks certainly make a difference! It's a biological imperative. But the question I have is why hasn't the self selecting gene pool been washed of all the ugly, deformed, misshapen, stupid , etc.? Is it that the beautiful have lower reproductive rates? How can that be when our notion of beautify is supposedly rooted in reproductive selectivity (things like large pelvis, voluptuous lips, broad shoulders, healthy cheek color, etc.)
I posit that we ugly SOBs are simply smarter! All you pretty folks just think you have an advantage because we want you to think that. Just look at who's doing the studies. It's us geeks who are not known for our drop-dead beauty (except for the few we salt within our ranks to throw you off) When was the last time you heard of a STEM beauty pageant?
So, just keep on thinking you're on top of it all; you're right where we want you.
