Building on various models for "intercultural and interreligious competence" (IC/IR competence), this essay argues that classroom learning about religious and cultural diversity will engage students' "sociological imaginations" and lead to increased IC/IR competence. The current strategy for increasing intercultural competence (attitude, skills and knowledge, to be developed in that order) does not reflect best practices for educating about social difference. Instead, "knowledge acquisition" about other cultures and religions is the "front line" task for increasing alterity competence, and the liberal arts classroom can represent a "safe space" for learning about cultural and religious differences in a depersonalized, sociological manner. Supporting this argument are self-assessments of IC/IR competence collected from primarily European and white American students enrolled in "Religions of the World" or "Intercultural Communications," allowing an analysis of IC/IR competence in light of the two distinct disciplines and contributing valuable data toward a broader theory of IC/IR pedagogy.
