First, YES. Duh.
Second, I'd like to throw out two more ideas about nerds in paleo.
1) I think we're a very internet-based movement (or at least it looks that way from my monitor!), which may account for the high percentage of nerd/computer oriented folk. Perhaps, too, the availability of information on the internet and ease with which we've been able to share it was a big contributor to (the beginnings of the) end of the Anti-Fat Monopoly.
2) The paleo diet and way-of-life requires an understanding of basic human history and science. And it requires an investment of mental energy. And maybe time, too, if we're going hiking and playing sports on the weekends and all of that. And this is why (I think), contrary to, say, weight watchers, the paleo movement generally floats in more highly educated circles.
Anyway. Woo!
