Disputing deindividuation: Why negative group behaviours derive from group norms, not group immersion

  • Stephen David Reicher (a1), Russell Spears (a2), Tom Postmes (a2) and Anna Kende (a3)


Strong social identity does not lead to lack of accountability and “bad” behavior in groups and crowds but rather causes group behavior to be driven by group norms. The solution to problematic group behavior is therefore not to individualize the group but rather to change group norms, as underlined by the relational dynamics widely studied in the SIDE tradition.
