Suffering from the possibility of status loss: Physiological responses to social identity threat in high status groups

In this research, we examine the emergence of social identity threat among members of high status groups, by assessing physiological responses to threat in addition to more traditional (self‐report) measures. We argue that physiological measures are better suited than explicit responses to indicate the emergence of social identity threat when high status groups face the possibility of future group status loss. In Experiment 1, members of an experimentally created high status group displayed higher systolic blood pressure (SBP) and pulse pressure (PP) when inter‐group status differences were unstable than when they were stable, even though participants in both conditions reported identical levels of collective self‐esteem. In Experiment 2, only male participants (i.e., high status group members) displayed increased SBP and PP when discussing changing gender–status relations in society, particularly when this happened in an inter‐group context (i.e., when discussing with females). The increased threat that emerged under these conditions could not be inferred from self‐reported inter‐group perceptions (endorsement of sexism). We conclude that whereas self‐report measures can help assess how high status group members perceive the current inter‐group situation, physiological measures are needed to reveal the social identity threat they experience when they anticipate the possibility for future change in inter‐group relations.
