How well do you understand your own biases? Is there a way to objectively identify your own biases, without the convoluted mess that is your own conscious meta-thinking?
Why yes, yes there is. Harvard has graciously posted online more than a dozen Implicit Association Tasks. This is a well respected, and kinda freaky, reaction time test that pairs symbols (often words, but can be pictures too) and tests how closely you associate them. It's a subtle and clever test and basically, unbeatable (you can try to *fake* your responses all you want, they'll catch you because of methodological design ... hint .. you can't go too slow).
I recommend everyone giving it a try, if only to get a taste off empirical cognitive science methods.
