A disbelief in human evolution was associated with higher levels of prejudice, racist attitudes and support of discriminatory behavior against Blacks, immigrants and the LGBTQ community in the U.S., according to University of Massachusetts Amherst research published in the Journal of Personality and Social Psychology.
The findings supported the hypothesis of lead author Stylianos Syropoulos, a Ph.D. candidate in the War and Peace Lab of senior author Bernhard Leidner, associate professor of social psychology.
“People who perceive themselves as more similar to animals are also people who tend to have more pro-social or positive attitudes toward outgroup members or people from stigmatized and marginalized backgrounds,” Syropoulos explains. “In this investigation, we were interested in examining whether belief in evolution would also act in a similar way, because it would reinforce this belief that we are more similar to animals.”

Religious beliefs, like political ideology, were measured separately from a belief or disbelief in evolution, the researchers note. “Regardless of whether one considers religion an important part of their life, belief in evolution relates to less prejudice independently from belief, or lack thereof, in God or any particular religion,” Syropoulos says.
