In this article, we explore how certain religious messages may spur or constrain
political participation. Specically, we test whether religious messages that provide
individuals a positive self image can act as stimulants, giving people a sense of internal efficacy to participate in politics. We explore this hypothesis through a novel experimental design in Nairobi, Kenya. We find that exposure to self-affiirmation messages typical of Pentecostal and Charismatic churches motivated participation in a political text message campaign. We discuss implications of these findings for politics in Sub-Saharan Africa, as well as for the study of religion and politics more generally. Files on this site allow for replication of the main results and figures in the article. Data for the experiment were generated in December 2013 and January 2014. Data for the follow-up survey on religiosity were generated in March and April 2015.
