This article discusses findings of a study that investigated the variance in critical thinking dispositions between arts and non-arts undergraduates. A consensus of findings in research literature on education and critical thinking indicates that an inquiry-based curriculum positively influences gains in critical thinking. Research shows, as well, that learning in the arts is largely inquiry-based. The synthesis of those findings and the results of this study indicate that exposure to learning in the arts positively influences students' disposition to think critically. The study reported in this article utilized quantitative data from the California Critical Thinking Disposition Inventory (CCTDI), a survey instrument. Data were collected from a sample of 141 undergraduates at a large, urban, public university on the U.S. east coast. The sample consisted of two discipline groups: arts and non-arts undergraduates; and two class rank groups: freshmen and juniors/seniors. As would be expected, when the class rank groups were compared, the juniors/seniors showed a significantly higher mean overall score on the CCTDI and were also found to have significantly higher scores on several of the subscales. Comparison of the two discipline groups showed no significant difference in overall mean CCTDI scores between arts and non-arts students, but the arts students were found to have significantly higher mean scores on several of the subscales within the research instrument: truth-seeking, maturity, and open-mindedness. These results suggest that learning in the arts builds strengths in several critical thinking dispositions and offers evidence that the arts do indeed enhance the disposition to think critically.
