This is important, not just for the specifics, but to remember that some pattern of behavior which seems absolutely innate is actually culturally localized.

I don't see why these specific patterns of behavior would seem "absolutely innate" even looking only at the U.S. There are lots of non-nerdy people with high intelligence, and I don't see any reason why they wouldn't excel in "nerdy" professions if they chose to enter them in large numbers. In my opinion, the main reason why non-nerdy smart people go mainly into non-technical professions is that in the American society, technical professions, on the whole, offer relatively low status considering the demands they impose.

So, are there geeky people in Europe? If so, what are they doing instead of science and engineering?

Where I lived in Europe (various places in ex-Yugoslavia), we've never really had anything comparable to the American notion of "geeks" and "nerds." It's hard to find even an approximate translation for these words which would have all the connotations of high intelligence combined with social ineptness, lack of masculinity, and obsessive interest in obscure and unpopular things.

We do have words that denote these qualities separately, or for people who put excessive effort into success in school while lacking real-life skills and smarts, or who achieve high grades thanks to cramming rather than smarts and talent, etc., etc., and various terms of this sort are used to translate "nerd/geek" in different contexts. But there is no accurate translation, simply because there is no striking correlation between all these attributes. (That said, in recent years some of the American "geek" culture has been making inroads, but even what exists of it is still not comparable, since there is both less social nerdiness involved and much less correlation with interest, let alone high achievement, in science and engineering.)

Partly this is because technical professions have higher relative status, so they attract plenty of intelligent people who are not at all deficient in social skills. The other reason is a very different youth culture and education system. As far as I see, these different circumstances usually tend to attenuate people's innate lack of sociability, rather than, as happens in the U.S., exacerbate it and force intelligent introverts to seek company and respect in "geeky" social circles and activities, since they can't find them anywhere else.

All that said, this situation still does not mean that success in courting women is more evenly distributed among men. On the contrary: the attention of attractive women, and the overwhelming part of casual sex that takes place, is still restricted to the minority of men who are attractive by pretty much the same criteria as anywhere else. It's just that you'll find many more such men (as well as less attractive, but still far from nerdy men) among people doing technical professions and having various intellectual interests that are stereotyped as "geeky" in the U.S.
