I number of times, I've referenced a study called "The Burden of Acting White" by Phillip Cook and Jens Ludwig.
I scanned it in and placed it on a personal website that I have. But I now see it's the Brookings Institution, so I'll point the link there.
The hat tip goes to Faheem (http://blackintrospection.blogspot.com) for the link. I've never been able to find it via Google.
More later. I have to live the real life...
