Beyond 'stampedes': Towards a new psychology of crowd crush disasters.

The Bethnal Green tube shelter disaster, in which 173 people died, is a significant event in both history and psychology. While notions of 'panic' and 'stampede' have been discredited in contemporary psychology and disaster research as explanations for crowd crushes, Bethnal Green has been put forward as the exception that proves the rule. Alternative explanations for crushing disasters focus on mismanagement and physical factors, and lack a psychology.

Self-categorization as a basis of behavioural mimicry: Experiments in The Hive.

Introduction: Do we always do what others do, and, if not, when and under what conditions do we do so? In this paper we test the hypothesis that mimicry is moderated by the mere knowledge of whether the source is a member of the same social category as ourselves.

Methods: We investigated group influence on mimicry using three tasks on a software platform which interfaces with mobile computing devices to allow the controlled study of collective behaviour in an everyday environment.

Results: Overall, participants (N = 965) were influenced by the movements of confederates (represented as dots on a screen) who belonged to their own category in both purposive and incidental tasks.

Inequalities and identity processes in crises: Recommendations for facilitating safe response to the COVID-19 pandemic.

Structural inequalities and identity processes are pivotal to understanding public response to COVID-19. We discuss how identity processes can be used to promote community-level support, safe normative behaviour, and increase compliance with guidance. However, we caution how government failure to account for structural inequalities can alienate vulnerable groups, inhibit groups from being able to follow guidance, and lead to the creation of new groups in response to illegitimate treatment.
