ACTUALLY DON'T DO IT IT'S A TRAP

J/k, it's not a trap. It's a website built by an international collaboration of psychology researchers. ^^ You can take tests that propose to show you how you really feel about whether women belong in careers, or whether black faces are more threatening than white ones, or whether thin people are inherently better than fat people. All kinds of controversial subjects~.
The spooooky thing about Project Implicit is that its claim to fame is showing that people can explicitly believe one thing and implicitly believe another. They can say 'I think all skin colors are beautiful, I don't have any preference', but then they take the test, and the results show something quite different. ;]
HOWEVER.
Before you jump in and start learning that you're a closet sexist/racist without even realizing it, I would like to point out a few things:
1) There is debate about the validity of the test itself...whether pressing a button to match a concept is actually measuring your beliefs or measuring something different...like, response time. Or memory for rules. Or attention span. =/
That last item probably applies to me...I keep forgetting what I'm doing in the middle of the test; sometimes I just sit there and stare at the word like I don't know what to do with it. How fast I press a button may not have anything to do with whether I think the concepts of 'old' and 'bad' belong together, it may just be that my brain happened to be on task then, or vice versa. Basically, if you're easily distracted, there's a chance your results might not even be accurate.
2) I don't think there's anything wrong with having implicit biases. I mean, sure, best case scenario is that we don't, but that just isn't feasible in today's world. America's civil rights movement was merely ONE generation ago; we're still new at this whole 'thinking of other human beings as equals' thing. So, so new...
Anyway, if it turns out that you do unconsciously believe that young people are better than old people or that women don't belong in the sciences, don't beat yourself up about it. I think your conscious beliefs are much more important in the grand scheme of things. I read this quote once that said: "Your first thought shows what you've been conditioned to believe. Your next thought shows who you really are."
