“…Appraising one's ingroup's disadvantage as illegitimate thus gives rise to anger (Van Zomeren et al, 2004), while appraising an ingroup's past actions as illegitimate can give rise to collective guilt or shame (Iyer, Schmader, & Lickel, 2007). These group-based emotions in turn influence specific action intentions: for example, anger predicts a desire to engage in collective action (Van Zomeren et al, 2004), shame predicts a desire to withdraw from a conflict (Iyer et al, 2007), and contempt predicts an orientation towards more radical or illegal forms of protest (Tausch et al, 2011). Other emotions shape collective action by inhibiting tendencies towards protest.…”
