Maybe I misunderstood. It sounded like you were suggesting that theists be baited with a honeypot (mate or group) that they'd like to be attractive to. The pressure to be liked would cause them to abandon their beliefs. I'm not saying this can't work, but it's a transformational pressure that works equally well in both directions. The person isn't better informed at the end of it, they're just trying to fit in with a group that happens to be more accurate.

(If atheism highly correlated with sexiness, maybe this would pull more people out of religion than in, but, in fact, religions are better at being organized into tribes with status anyway)

But, I think, given your response, that I've misread you. Can you correct me?
