Title got your eye? Well, two pieces of research, ahem, underly it.
This article points out altruism as a marital advantage. Contra this, a truly stunning number of people (-: no, they’re not all blokes :-) see the most fundamental part of marriage as being the mattrial (or elsewhere, regarded as safer if it’s private) oscillations; while this aspect does have a definite and important role to play, this study (linked from the above article too) reinforces the other by carefully and scientifically determining from their subjects that love is by and large a far more powerful motivator than the odd excitable ex— I mean, er, conclusive oscillation session, implying it to remain thoroughly so even with the imaginable [by me, anyway, sans emesis] leather/air/flavoured/etc aids and such.
Since many geekoid acts are at some level altrusitic and since many geeks like to — tongue-in-cheek at last — carefully l\bstick down every detail in a situation, the results for Mr and Mrs Geekish (or even a one-half-geekoid marriage-type situation) are looking quite... well... “attractive” is probably the most appropriate Anglic word to use, and a relatively safe one as well.
Now, I know that this is an imperfect Universe, but within it I tend to accept the good parts as they become available and dodge the nasties likewise (one notable failure a couple of months ago, which has in fact remarkably avoided being the total disaster I would expect, hurrah!) — this part’s looking quite beneficial now, despite me having already surfed far more goodness than such a non-attractive event foreshadowed. I’ll (a little rashly, I guess) take it as a kind of continuation of those unreasonable goodlets and watch carefully.
