Collective action

Collective action refers to action taken together by a group of people whose goal is to enhance their status and achieve a common objective. It is enacted by a representative of the group. It is a term that has formulations and theories in many areas of the social sciences including psychology, sociology, anthropology, political science and economics.

Researchers Martijn van Zomeren, Tom Postmes, and Russell Spears conducted a meta-analysis of over 180 studies of collective action, in an attempt to integrate three dominant socio-psychological perspectives explaining antecedent conditions to this phenomenon – injustice, efficacy, and identity. In their resultant 2008 review article, an integrative Social Identity Model of Collective Action (SIMCA) was proposed which accounts for interrelationships among the three predictors as well as their predictive capacities for collective action. An important assumption of this approach is that people tend to respond to subjective states of disadvantage, which may or may not flow from objective physical and social reality.

Examining collective action through perceived injustice was initially guided by relative deprivation theory (RDT). RDT focuses on a subjective state of unjust disadvantage, proposing that engaging in fraternal (group-based) social comparisons with others may result in feelings of relative deprivation that foster collective action. Group-based emotions resulting from perceived injustice, such as anger, are thought to motivate collective action in an attempt to rectify the state of unfair deprivation. Meta-analysis results confirm that effects of injustice causally predict collective action, highlighting the theoretical importance of this variable.

Moving beyond RDT, scholars suggested that in addition to a sense of injustice, people must also have the objective, structural resources necessary to mobilize change through social protest. An important psychological development saw this research instead directed towards subjective expectations and beliefs that unified effort (collective action) is a viable option for achieving group-based goals – this is referred to as perceived collective efficacy. Empirically, collective efficacy is shown to causally affect collective action among a number of populations across varied contexts.

Social identity theory (SIT) suggests that people strive to achieve and maintain positive social identities associated with their group memberships. Where a group membership is disadvantaged (for example, low status), SIT implicates three variables in the evocation of collective action to improve conditions for the group – permeability of group boundaries, legitimacy of the intergroup structures, and the stability of these relationships. 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.
