The researchers studied 120 non-black participants who volunteered for the experiment and either directly experienced a racial incident or had the incident described to them. The first group watched a black man, posing as a fellow participant, slightly bump a white confederate also posing as a participant. After the black man left the room, the white confederate either said nothing, or “I hate it when black people do that,” or said, “clumsy n____.” Other groups did not directly experience the event but either read about it or watched it on videotape and were asked to predict their responses to the events.

The subjects who didn’t experience the event were much more likely to report that they were upset at the white worker’s slurs and to say they would not work with such a person. Those who actually experienced the event were less distressed and were as willing to work with the person who made racist comments as someone who did not.
