Deindividuation is a process where individuals lose self-identity and self-restraint while in group settings, leading to unusual or non-normal behavior. When people feel anonymous and part of a larger group, they no longer see themselves as individuals responsible for their actions. This depersonalization allows them to engage in behaviors they would normally avoid, such as theft or vandalism, because personal accountability disappears in the crowd.

Le Bon proposed that when individuals gather in a group, consciousness shifts away from the individual toward the group. As the individual's conscious personality fades, the group's unconscious personality takes over. This shift causes individuals to adopt whatever qualities the group embodies—destructive, political, or tyrannical—even if they would never exhibit such behavior alone.

Festinger's experiments showed that students who expressed harsh opinions in group discussions made more errors identifying who said what and rated the group as more attractive. This demonstrated a positive correlation between relaxing personal restraint in groups and losing recognition of individuals as distinct people. The findings suggested that losing individuality to the group increases group appeal.

Anonymity is a key factor making individuals vulnerable to deindividuation and crowd dynamics. When people are disguised or unidentifiable, they feel less personally responsible for their actions. This anonymity removes the fear of social evaluation and personal consequences, allowing disinhibited behavior to emerge more readily in group settings.

A meta-analysis by Postmes and Spears found a strong association between deindividuation and situational norms, suggesting that crowds trigger deindividuation because individuals become more responsive to group norms. This challenges earlier models emphasizing reduced personal restraint, instead proposing that deindividuation functions through conformity to the situation's social expectations.

Zimbardo's model proposes deindividuation occurs when self-observation decreases and social evaluation value increases, potentially enabling pro-social behavior. However, later research emphasizing situational norms suggests deindividuation operates through conformity to group expectations rather than simply reduced personal restraint. This shift represents a fundamental change in understanding how group dynamics influence individual behavior.

Individuals are vulnerable to deindividuation when self-awareness decreases in group situations. Lower self-awareness means people are less conscious of their individual identity and personal standards, making them more susceptible to group influence. This reduced self-monitoring allows behaviors that conflict with personal values to emerge more easily within the group context.
