Background: Psychological misconceptions permeate our culture, with many people endorsing these erroneous beliefs. Objective: The purpose of this study was to replicate and extend previous findings that reported psychology knowledge and cognitive thinking style predict undergraduates' beliefs in psychological misconceptions. Method: Two hundred and ninety-six undergraduates participated in an online survey in which they completed a psychological misconceptions questionnaire and the Critical Reflection Test (CRT). Participants' academic information (i.e., number of psychology and non-psychology courses taken and overall psychology GPA) was retrieved via institutional data. Results: Number of psychology courses, psychology GPA, and CRT score were all positive correlates of rejecting psychological misconceptions. Conclusion: Students who took more and attained higher grades in psychology courses and engaged in more reflective and analytical thinking are less likely to affirm psychological misconceptions. Teaching Implications: Psychology courses, particularly those that include activities and assessments to bolster reflective and analytical thinking skills, could be effective means to reduce students' beliefs in psychological misconceptions.
