In three studies we investigate the impact of mortality salience on conformity and show that people have a greater preference to conform to the opinions of others when mortality is salient. Study 1 shows that mortality salience increases the degree to which judgments of abstract drawings are influenced by the majority's opinion. Study 2 shows that mortality salience causes people to change their opinions towards societal issues, so that these fit the attitudes they think others have. Study 3 replicates the findings of the first study and additionally shows that people do not conform to the attitude of outgroup members. Our findings extend previous Terror Management Theory research and suggest that conforming to the group is a means to buffer the fear that may otherwise arise in existentially threatening situations.
