For example, when disadvantaged groups perceive intergroup status relationships as illegitimate and unstable, collective action is predicted to occur, in an attempt to change status structures for the betterment of the disadvantaged group.

Meta-analysis results also confirm that social identity causally predicts collective action across a number of diverse contexts. Additionally, the integrated SIMCA affords another important role to social identity – that of a psychological bridge forming the collective base from which both collective efficacy and group injustice may be conceived.{{Citation needed|date=October 2016}}
