“If you wrong us, shall we not revenge?” Social identity salience moderates support for retaliation in response to collective threat.

Researchers have recently asserted that social identity salience moderates the way in which people react to external stressors. However, previous research has mainly investigated this idea in the context of internal coping processes in response to personal threat. The present research examines people's willingness to respond to collective threat by means of aggressive acts of revenge. A study with 80 female participants revealed that aggressive revenge intentions were most pronounced when the form of collective threat was relevant to a currently salient social identity. Specifically, we found that a threat to national identity (the 7/7/2005 London bombings) led to greater aggression and greater support for revenge when national rather than gender identity was salient. In contrast, a threat to gender identity (Taliban misogyny) led to greater aggression and greater support for revenge when gender rather than national identity was salient. Implications for research on social identity, stress, and responses to terrorism are discussed.
