Social connection enables dehumanization

Being socially connected has considerable benefits for oneself, but may have negative consequences for evaluations of others. In particular, being socially connected to close others satisfies the need for social connection, and creates disconnection from more distant others. We therefore predicted that feeling socially connected would increase the tendency to dehumanize more socially distant others. Four experiments support this prediction. Those led to feel socially connected were less likely to attribute humanlike mental states to members of various social groups (Experiments 1 and 2), particularly distant others compared to close others (Experiment 3), and were also more likely to recommend harsh treatment for dehumanized others (i.e., terrorist detainees, Experiment 4). Discussion addresses the mechanisms by which social connection enables dehumanization, and the varied behavioral implications that result.
