The dark side of morality: Prioritizing sanctity over care motivates denial of mind and prejudice toward sexual outgroups.

Moral values bind communities together and foster cooperation, yet these same values can lead to the derogation and marginalization of outgroups. Five studies tested a theoretical framework proposing that preferentially endorsing moral values of sanctity versus care (the sanctity-care trade-off) produces a motivational bias whereby people perceive sexual outgroup members as less human. This denial of mind, in turn, legitimizes expressions of prejudice and discrimination toward sexual outgroups. Study 1 showed that natural variations in people's moral values predicted denial of mind and prejudice. Study 2 replicated this pattern, examining political liberals and conservatives, and demonstrating that moral values and denial of mind help explain the relationship between personal politics and prejudice. Study 3 measured people's moral values by examining people's willingness to trade-off a moral value for money and used this measure to predict denial of mind, prejudice, and decreased willingness to help transgender individuals. Study 4 used religion to boost sanctity values and found a corresponding increase in denial of mind and prejudice. Finally, Study 5 reduced denial of mind and prejudice by intensifying concerns about care. Together, these studies demonstrate that moral values importantly influence how people decide who possesses a mind and is entitled to moral rights and who is mindless and allowed to be hurt or neglected.
