Background: Psychology students frequently continue to endorse psychological myths and misconceptions. The refutational method of instruction can reduce myth endorsement. Objective: This study aimed to replicate and extend prior research using infographics to refute psychological myths and misconceptions. Method: Undergraduate students in two online courses (N = 46) completed refutational infographics on assigned myths and shared them in groups. Researchers assessed myth endorsement and critical thinking attitudes and beliefs at the beginning and end of the project. Results: Post-project myth endorsement was significantly lower for students' assigned myths and other myths that peer groups exposed them to. Attitudes and beliefs about critical thinking were significantly higher at the end of the project. Conclusion: Refutational infographics are associated with lower psychological myth endorsement and increased critical thinking attitudes and beliefs among intermediate- and upper-level psychology students. Exposure to peers' refutational infographics is also associated with reduced myth endorsement. Teaching Implications: Instructors seeking ways to correct myth endorsement while fostering positive perceptions of critical thinking should consider using refutational infographics with a sharing component.
