In-group bias is a widely recognized phenomenon. In recent survey data, every group measured–from black conservatives to Asian-moderates–shows a significant, and unsurprising, in-group preference. Except for white liberals, who show significant out-group bias–meaning white liberals prefer nonwhites to whites.
[…] Out-group bias is not shared by liberal Asians, Latinos or African Americans, all of whom have more typical in-group preferences.
The recent GenForward survey from the University of Chicago, the first nationally representative survey of youth focused on race and ethnicity, suggests that young white liberals harbor a dislike for whites. (I am indebted to Zach Goldberg, a doctoral student at Georgia State University, who graphed all of the survey data presented here.)
When looking at the GenForward data (all surveys were done confidentially online to minimize social desirability bias), whites of all ethnic groups had the lowest in-group bias, with moderates having a slightly higher bias than white conservatives. This would seem to counter the notion pushed by many on the Left that contemporary conservatism is some sort of stalking horse for white nationalism.
Using the even larger American National Election Studies (ANES) dataset that includes voters of all ages, we observe the same phenomenon. African-Americans show the highest in-group bias independent of ideology.
