Relative deprivation and revolt: current and future directions.

We review research applying relative deprivation theory to comprehend social, economic, and political phenomena relating to social change. We highlight areas illuminated by relative deprivation and limitations of this contemporary research. Next, we outline four theoretical elaborations of relative deprivation theory to advance understanding of complex socio-economic and political processes of underlying rallies, riots, and revolutions. We end by suggesting methodological approaches and research agendas to understand psychological processes of social change.
