Jumping off a Steven Medvic post, Phil Klinker rounds up data from the 2004 NES which shows that about half of white people think African-Americans are lazier than whites, almost 40 percent say that African-Americans are less intelligent than whites, and again about 40 percent of whites say that African-Americans are less trustworthy.

Think about the implications of that for, say, a black job applicant for a position for which there are also some white applicants who seem reasonably qualified. It'd be interesting to see something about the age structure of adherence to these stereotypes, or else a time series presentation of this information, so we could get a sense of how much things are likely to change over time.
