That's an interesting analysis, but I disagree on some points. My ideas:
1) people tend to have sex with people of roughly the same attractiveness. Only a fool would fail to realize that there's a sexual market out there, and one's price in that market is mostly dictated by looks, not intelligence or interests. (disclaimer: I live in Southern California, and I realize that I may sound overly superficial).
2) Sex and stable romantic relationships are way different things. It's true that people tend to start relationships with people of roughly the same intelligence, socioeconomic status, and interests... but come on! I would not turn down a funny, hot girl just because she's an English major who's not interested at all in Quantum Field Theory! I probably would not want to marry her, but some NSA fun once in a while is refreshing...
3) Grad students at MIT should be rather smart, driven people. They should be surrounded by people of the same intelligence and interests, and they still don't get laid much. Your cute analysis does not explain this.
1.) I think it's both. People have sex with folks of the same attractiveness, but they don't ignore intelligence. Could you imagine an MIT grad student having sex with a trailer-trash bimbo of slightly-below-average attractiveness? (Yeah, that's a bad mental picture.)
3.) They've had less time to be surrounded by people of similar intelligence and interests. The virgin rate among MIT grad students is roughly the same as the virgin rate among average high schoolers. That's consistent with the hypothesis that MIT-caliber grad students can't find anyone until they get to MIT, and then they follow the normal rules of chance & dating & random hookups that most people do in high school.
