I've only ever seen one case of a man who'd previously had a rationalist mate going back to nonrationalist mates afterward. The reason why the gender skew of our culture is a mating problem for men is that once you go rationalist you don't go back.
"Go to the physics department, find a woman you consider attractive, point her at HPMOR, and see if anything develops" sounds like more useful advice to me.
For (straight) men who insist on dating externally, asking a woman whether she would prefer a certainty of $500 or a 15% chance at $1 million seems likely to be a surprisingly good filter on potential mates. I didn't believe it either as first, but I've verified that many women, and in at least one case a female grad-student doing advanced math homework, says she would rather have the $500; while every woman I've tested inside our community - regardless of her math/science/economics level or her ability to talk glibly about explicit rationality - takes the 15% chance at $1M with a puzzled look and 'Is this a trick question?'
I would be curious to know how people answer given the opportunity to spend $500 on a $1M/15% lottery ticket.
That depends a lot on the nature of the lottery. If it was a typical lottery that for some reason had a 15% chance to win, a $500 ticket would not be worth it as all, since thousands of people would win and split the prize amongst themselves and the expected value would be much less than you would assume at first glance.
If it's just "spend $500 for a 15% chance of gaining a million," though, I'd take as many tickets as I could get!
Yes, that version seems much less problematic, and I think the average person might be in favor of buying infinity tickets.
I might actually not want to buy one. (When no loss is involved I take the chance at a million.) I might want to buy five, or go in together with several friends on one.

What if I gave you $500, then asked you if you wanted to spend it on the ticket?
I'd also like to know whether some unexpected expense, like needing a $500 dental crown, would change your mind about accepting the free $500 instead of the free ticket.
If you gave me $500 and then immediately alerted me to the availability of a ticket you'd probably catch me before the $500 entered the "my money" mental bin, because I'd still be a little confused about why you randomly handed me $500 and expect to have to give it back.
Risks of medium-sized unexpected expenses like that are already factored into how conservative I am about handling money on this scale, so I don't think that would have an effect.
