Political Identity and Vulnerability to Radicalism Among Brazilian Evangelicals
Description
This dataset contains data from a cross-sectional quasi-experimental study with 1,612 Brazilian evangelical adults (69.98% female; mean age = 39.9 years, SD = 12.5). Participants completed measures of sacred values across five moral domains (Abortion, Same-Sex Marriage, Church–State Relations, Support for Israel, and Gender Education) under three experimental conditions (Taboo, Taboo+, Taboo−), the Need for Cognitive Closure Scale (NCC-15), and the Big Five Inventory (BFI-20). Data were collected online via Google Forms between November 2024 and September 2025. The dataset includes sociodemographic variables (age, gender, education, income, religious affiliation, political orientation), NCC total and facet scores, Big Five personality trait scores, binary indicators of moral rigidity for each domain, total sacralization score, and experimental condition assignments. All data are anonymized. Analyses were performed using JASP (version 0.19.3)
