This is a revision of WP 84-4. The authors develop an explicit theoretical foundation for the common belief that legitimation is somehow important in mobilizing collective action. They distinguish validity of a rule (collective support) from propriety (individual support) and predict that validity affects mobilization independent of propriety. Results of an experimental test support the derivations.
Thomas et al. (Mon,) studied this question.
