Liberals pretend to support black candidates?

Noam Scheiber points to working paper, SOCIAL DESIRABILITY BIAS IN ESTIMATED SUPPORT FOR A BLACK PRESIDENTIAL CANDIDATE, which attempts to figure out the Bradley Effect by guaging avowed vs. implied support.

To a great extent I think this is the sort of thing which should give us caution about overreading from social science; you might not be smoking out the dynamics which you think you are smoking out. I’ve put the results from the most relevant table below the fold; remember that “True Support” is a calculated projection, and if you are curious about p-values just go to the paper itself.
