An amusing post, Prejudice, Beautiful Prejudice, by Ben Goldacre from his Badscience column in The Guardian newspaper, where he attempts some statistical analysis of the data captured at Am I Hot or Not?. I especially like:

...my experimental aspirations were torpedoed when I discovered that the attractiveness scores are blanked out when you search by keyword. I have no idea why, but this sort of problem often occurs when you try to crowbar population datasets into purposes for which they were not originally devised. [...] Then I had a thought: [...] Why don’t I just email Amihotornot HQ? So I did. But they haven’t got back to me. I think they’ve just assumed I’m some kind of weirdo.

badscience is always worth a read - I sometimes think it should be funded as a public service....but then of course it is independence which makes it valuable. Ben Goldacre, more power to you!
