Racial and religious prejudice increased significantly among former president Donald Trump’s supporters during his presidency, according to studies published Monday by the journal Nature Human Behavior.
The 13 studies involved more than 10,000 participants.
Researchers and social psychologists, Benjamin Ruisch of the University of Kent in the U.K. and Melissa Ferguson of Yale University, found Trump opponents showed decreases in prejudice.
A scholar not involved in the studies said the findings were what most social scientists would expect.
Another scholar cautioned that prejudice had increased on both the left and the right.
The studies also examined prejudice against Muslims, Blacks, and other minority groups.
