Finally a Unifying theory

So I have been a nerd for a long time. And during this time I have found myself getting in discussions (more like being talked at) about nerd girls and how hot they are. This ranges from fictitious comic
book super ladies to real life Angelina Joe Lee as tomb raider. I now have my own theory on the matter. And it is summed up by one word...Redheads. For some reason they keep popping up in different sci-fi and fantasy based nerd stuff. Here is my proof.

It started in the 90's with star treks Beverly Crusher (Gates McFadden).

But more recently we have seen an explosion of redheads in Nerd-land. I have no explanation except it is an empirical law of nerds....We like redheads.
