This study examined the prevalence of psychological myths and misconceptions among psychology students and within the general population. In total, 829 participants completed a 249-item questionnaire designed to measure a broad range of psychological myths. Results revealed that psychological myths and misconceptions are numerous and widely held. A number of widely held, potentially harmful, and socially divisive myths were identified. Psychology students recognized more myths than did the general population. However, effect sizes were small, indicating that education has only a very limited success in alleviating psychological myths and misconceptions.
