Intergroup differences in the sharing of emotive states: neural evidence of an empathy gap

Empathy facilitates prosocial behavior and social understanding. Here, however, we suggest that the most basic mechanism of empathy--the intuitive sharing of other's emotional and motivational states--is limited to those we like. Measuring electroencephalographic (EEG) alpha oscillations as people observed ingroup vs outgroup members, we found that participants showed similar activation patterns when feeling sad as when they observed ingroup members feeling sad. In contrast, participants did not show these same activation patterns when observing outgroup members and even less so the more they were prejudiced. These findings provide evidence from brain activity for an ingroup bias in empathy: empathy may be restricted to close others and, without active effort, may not extend to outgroups, potentially making them likely targets for prejudice and discrimination.
