A recent study published in the Journal of Experimental Psychology: Applied by Florida State University (FSU) Professor Michael Bishop reveals that a critical thinking course can lead to significant long-term reductions in common reasoning biases among students. The study focused on four specific biases: honoring sunk costs, inferring causation from correlation, the regression fallacy, and overlooking opportunity costs. Bishop's research indicates that students who completed the course demonstrated improved reasoning skills not only at the end of the semester but also 16 months later, showcasing the lasting impact of effective critical thinking education. The course involved a two-phase learning process, where students first committed to understanding correct reasoning and then recognized its application in various scenarios. This study underscores the potential for critical thinking courses to enhance decision-making in personal and professional contexts, suggesting that many individuals can improve their reasoning abilities significantly. The findings may inform future curriculum designs for critical thinking courses across educational institutions.
