Evidence Based Decision Making

There's a dating website called OKCupid that, among other things, has had a lot of interest among my social group for its personality quizzes. You know, what's your dating personality, how would you survive in a zombie apocalypse, that kind of thing. They've also realised that they're sitting on an enormous pile of data of people talking about themselves and communicating with each other, and have started publishing statistical analyses. Some of them are pretty funny, others are practical, and still others head into the territory of a bit disturbing. (My gender and ethnicity is apparently one of the most stand-offish when it comes to replying to first messages from people on the site. Er, sorry?) Even with (or because of?) a self-selection bias out the wazoo, these articles are really interesting if you like thinking about what makes people tick.
