I heard about (literally, audiobooks ftw!) this test a few months ago, but it immediately dropped out of my mind until I randomly stumbled across it. Basically it judges your ability to judge armed vs. unarmed targets and differentiates your score based on race.
Pictures flash on the screen. Some of the pictures have people in them. Some of those people are holding guns, and some of those people are holding cellphones. Some of those people are black, and some are white. You press a button to differentiate the guns from the phones, or, to quote the test exactly: to shoot or holster your weapon.
Your Score: 535
Average reaction time:
I have no idea what this means. No, really.
Apparently I am quicker to judge black people than I am whites. In other words, it takes me longer to decide whether a white person is armed or not… but only slightly. If a black person was armed, I reacted in 551ms. If a black person was unarmed, I reacted in 645ms. For whites, however, those same times are 556 and 653ms, respectively. It takes me 5ms longer to decide if an armed white person is armed vs. an armed black person. Again… no idea if this is a good or bad reaction time, nor was there any information to let me know if the time differences were significant or not. How much of a time difference means you’re a racist? No idea.
But it was a fun test.
And, in the interest of full disclosure, I DID shoot about five unarmed people just for the hell of it.
