Some evidence for the nonverbal contagion of racial bias

• Racial bias is expressed through subtle nonverbal behavior.
• Through passive observation, we can “catch” others’ racial bias.
• Prejudice and discrimination transcend the actor and target affecting those merely observing.

Four experiments provide evidence for the hypothesis that we can “catch” racial bias from others by merely observing subtle nonverbal cues. Video recordings were made of white participants (with varying levels of racial bias) interacting with a neutral black confederate. Videos contained subtle expressions of positivity or negativity, corresponding to white participants’ levels of bias. Participants randomly assigned to observe the subtle anti-black bias videos (vs. pro-black) formed more negative impressions of the black person (Experiment 1), adopted more negative racial stereotypes (Experiment 2), and demonstrated greater anti-black bias themselves (Experiment 3). Participants only demonstrated increased bias when they knew that a black person was the target (vs. white; Experiment 4). Results suggest that nonverbal expressions of racial bias affect more than simply the actor and target—they affect passive, naïve observers. The good news, however, is that the same is true of pro-black bias. Implications for organizations are discussed.
