A new study by researchers at the University of Geneva and New York University shows that racism impacts activity in the brain. Participants in the study were shown faces of White and Black people while researchers monitored activity in the area of the brain that is involved in perception. Subjects were later asked to take a survey which measured their level of subtle racial bias.
For subjects who tested high on racial bias, researchers could determine with high accuracy the race of the person in the photograph simply from the activity in the brain of the test subject. The authors of the study conclude that people with a high degree of racial bias actually perceive Black and White faces differently on the neural level.
The study, published in the journal Psychological Science, was funded in part by the National Institutes of Health, the Seaver Foundation, and the Swiss National Science Foundation.
