Deindividuation and antinormative behavior: a meta-analysis
Abstract
A meta-analytic integration reviews evidence for deindividuation theory as an explanation of collective and antinormative behavior. Deindividuation theories propose a subjective deindividuated state that causes transgression of general social norms. Deindividuation research classically manipulates anonymity, self-awareness, and group size. Results of 60 independent studies showed little support for (a) the occurrence of deindividuated (antinormative) behaviors or (b) the existence of a deindividuated state. Research results were explained mon adequately by situation-specific than by general social norms. Analyses indicated that groups and individuals conform more to situation-specific norms when they are "deindividuated." These findings are inconsistent with deindividuation theory but support a social identity model of deindividuation effects.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
