Deliberative Thinking Increases Tolerance of Minority Group Practices: Testing a Dual-Process Model of Tolerance

Tolerance of minority beliefs and practices is typically considered a critical ingredient for an equal and diverse society. Psychologically, people can use both intuitive and deliberative cognitive sources to make tolerance judgments. Following dual-process theories, this research uses survey experiments to manipulate intuitive versus deliberative thinking to examinewhether deliberative thinking increases tolerance of minority practices. Across three studies using nationally representative samples of Dutch majority members (N = 1,811), we find that deliberative thinking increases tolerance, regardless of whether people deliberate over pragmatic or principled reasons for accepting contested minority practices and social changes. These findings are similar across a range of minority practices and robust across gender, age, educational level, and political orientation.
