This was a discussion a month ago. I'm mostly basing my opinion on it.
- the John/Jennifer study http://www.yalescientific.org/2013/02/john-vs-jennifer-a-bat...
- the chairs study http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.465...
- the police shooting armed people in VR study http://www.washington.edu/news/2003/07/08/blacks-more-likely...
- the general idea of "stereotype threat" (which becomes unrelated, not as much of an offshoot)
I am not expecting you to spend the time to vet every single of those links (and admittedly I used google, so some of the links might be overly editorialized), however I do believe these are good resources to consider for inclusion in your intellectual toolkit when you have the time.
