Background / Metatheory:
The Social Identity Theory of Collective Action is one of the derivates of Social Identity Theory (Tajfel & Turner, 1986). The purpose of the theory is to explain when people engage in collective action.

- ingroup_identification - individual’s perception of their identity as closely connected to the ingroup
- perceived_group_efficacy - individual expectation of whether collective action as a group would be effective in improving the group conditions
- perceived_injustice - individual perception of unfair group inequality
Scope Conditions:
- ingroup must be a preexisting group
- ingroup must be a group that becomes structurally or incidentally disadvantaged
Propositions:
- the more ingroup identification, the more collective action
- the more perceived injustice, the more collective action
- the more perceived group efficacy, the more collective action
Derivations:
- ingroup identification, perceived injustice and perceived group efficacy must be present for collective action
