Put yourself in situations where the people you’re attracted to have to spend a fair amount of time talking with you. Initial snap judgements can be overcome after a few hours of interaction. You probably won’t be able to date a celebrity this way (although if you live in LA and work in the film industry, I will adjust my probabilities) — but you can absolutely meet and date attractive people that way.
(Why’d you edit out your question? I thought it was interesting!)
