It's a fun little game. Shoot the guys with the gun, not the guys with wallets and cell phones. You won't do it perfectly (and neither do cops).
You face around 100 people, my guess is half are black, half are white, half are armed, half are unarmed. All in all, it takes less than 5 minutes (including loading time).
When it's over it gives you a score and also the response time for armed and unarmed white and black men. Here's mine:
Your Score: 660
Average reaction time:
I think my overall score is pretty good. But the racial difference in response time is interesting. Of course I don't think I'm more likely to shoot black men. Besides, like any good cop, I'm not looking at race. I'm looking at their hands.
But the numbers show that I'm quickest to respond to an armed black man and slowest to respond to an unarmed black man. Mind you the difference is only 7/100th of a second, but still....
This kind of racial bias in consistent with most academic research that finds differences in response time towards white and black armed and unarmed suspects.
Feel free to cut and paste your scores in a comment.
