4/16/2008 Karl-Dieter Opp, Collective Identity, Rationality and Collective Political Action
This paper explores the effects of collective identity on protest behavior by applying an extended version of the theory of action. Hypotheses are derived on the following questions that are rarely addressed in the
literature: Has identity only additive effects or also multiplicative effects? Are there situations when collective identity diminishes protest?
Does collective identity have indirect effects - via the determinants of protest - on protest behavior? Are there feedback effect of protest participation on collective identity? The hypotheses that address these questions are tested by a three-wave panel study. Three findings seem most important. (1) The overall direct effects of identity on protest behavior are small. (2) We provide evidence that under certain conditions identity does not raise but reduce protest. (3) The major effects of identity are indirect: identity influences the determinants of protest.
