One thing struck me in reading your piece: using an example of women who outperformed men in tests & thus might be considered smarter to suggest men don't really want to date smart women.

Smart ≠ smarter.

Do they emasculate? Or are they potentially a poor long-term match?

I've been married for forty years now to a woman who is plainly smarter than me. But that's offset by the fact of our different skills. Intelligence, as you point out, is a difficult quality to define precisely. Yes, she's smarter, but I know a lot more about most things. So we do complement each other.
