Scientists Use Brain Measurements to Identify a Video that Significantly Lowers Racial Bias
Researchers Yilong Wang and Paul J. Zak identified a short, highly immersive video about Black astronaut Dr. Ronald McNair that measurably reduces racial bias. In a lab test of 62 participants, the video generated the strongest neurologic "Immersion" response, prompting a larger field experiment with 1,097 U.S. adults. Viewers of the video reported an 11% drop in negative attitudes toward Black Americans and showed a 104% increase in generosity toward Black‑named partners in an ultimatum game. Follow‑up testing confirmed that these attitude and behavior shifts persisted for at least two weeks.
Belief in the Harmfulness of Speech Is Linked to Both Progressive Ideology and Symptoms of Depression
