Debunking Psychology Myths: How Misconceptions Form and How Educators Can Correct Them

Summary

The podcast explores common misconceptions about psychology that persist even after taking an introductory course. Dr. Erin Smith explains the origins of a large, multi-campus study on 40 misperceptions, how belief in myths can endure, and the challenges of debunking them without reinforcing the false idea. The discussion emphasizes the role of memory, repetition, and online echo chambers in spreading myths, and it highlights teaching practices that actively engage students to revise their beliefs.

• Large scale study of intro psychology misconceptions across eight campuses and about 900 students.
• Top myths include subliminal influence and learning styles, which are hard to dislodge.
• Misconceptions are not wholesale beliefs but fragile, context dependent beliefs that require targeted debunking.
• Effective correction borrows from active learning, memory generation, and critical evaluation of sources, including AI tools.

Overview and Context

The podcast features a detailed interview with Dr. Erin Smith, the Fletcher Jones Endowed Professor of Research and a psychology professor at California Baptist University. Dr. Smith is a developmental psychologist whose work spans the psychology of religion, social support in church settings, and the pedagogy of psychology education. In this episode of Speaking of Psychology, the flagship podcast of the American Psychological Association, the focus is the prevalence and impact of misconceptions about psychology among college students who have completed an introductory course. Dr. Smith and host Kim Mills discuss a multi authored paper examining college students’ beliefs about 40 misperceptions, the origins of the project, and the educational implications for how introductory psychology should be taught to foster critical thinking and scientific literacy beyond memorization of facts.

The origin story begins at a conference led by Doug Bernstein in 2018, which aimed to rethink how psychology is taught as a gateway course for majors and non majors alike. The project gathered scholars from North American and European universities to talk about how to educate students to reason according to sound science and to interpret psychological phenomena with robust empirical support. The study gathered roughly 900 students across eight campuses, including private religious, non religious, and large state universities. At the end of the Intro to Psychology class, students completed a quiz known as “quiz about people,” featuring 40 commonly held misperceptions about psychology and behavior. The researchers sought to learn whether and which misconceptions persisted after the course and what factors might predict persistence or correction.

Methodology and Key Findings

Dr. Smith explains that misconceptions are not a uniform set of beliefs that all students either adopt or reject wholesale. Rather, individual students may endorse some misperceptions while rejecting others, producing a mosaic of beliefs that vary by person and context. This fragmented pattern makes debunking challenging because endorsement of one misconception does not reliably predict endorsement of another. Yet a consistent pattern emerged: when professors report spending intentional time and energy addressing a particular misconception, students are more likely to identify it as a misconception. This suggests that targeted, explicit debunking in courses can be effective, even if broader trends indicate persistence of beliefs in some domains.

Among the most persistent misperceptions are subliminal messaging and learning styles. Smith notes that the latter, often framed as “I learn best when taught in my preferred learning style,” remains stubbornly entrenched despite evidence that learning styles do not reliably predict learning outcomes. The persistence of such beliefs is consistent with broader cognitive and educational psychology literature that emphasizes how beliefs form and resist revision.

Why Misconceptions Are Sticky

The conversation delves into why misconceptions spread and persist. Normal human psychology contributes to their stickiness: our memory systems are trained to reinforce information through repetition. Repetition increases belief, even when the information is false. In addition, the digital information ecosystem amplifies exposure to purported misperceptions, often through echo chambers that reinforce group identity and moral emotion. The host and guest discuss a paradox of debunking: clearly stating a misconception is false can in some cases reinforce the memory trace of the myth simply by repeated exposure to the claim and its correction. This dynamic highlights the need for careful, evidence based approaches to debunking that minimize reinforcing the myth while increasing accurate recall and understanding.

Internet and Echo Chambers

The role of social media is a central concern. The podcast describes how ideological echo chambers can heighten moral outrage and shape perceptions of what “the group believes.” When information travels through multiple mouths, but originates from the same root source, the impression of multiple voices may be misleading. This phenomenon can make misperceptions appear more widespread than they are, which in turn makes individuals more likely to adopt beliefs that align with their social identity. The podcast notes that debunking requires substantial effort and perseverance, particularly for busy individuals who lack the bandwidth to engage in rigorous source evaluation. The practical upshot is a call for more accessible, accurate, and engaging information delivery to offset the pull of online misinformation.

Individual Differences in Belief Endorsement

In examining how beliefs correlate with demographic and academic factors, the researchers found that students with higher GPA were more likely to reject misconceptions. This pattern aligns with the notion that greater academic engagement, critical thinking, and follow through with reasoning from question to conclusion support more accurate beliefs. The data also revealed gender differences, with female students more prone to endorse misconceptions, a finding the authors acknowledge as needing further exploration to understand potential influences of science identity, confidence in argumentation, and contextual activation of reasoning. These findings suggest that interventions may need to consider student identity and confidence in scientific reasoning as part of the remediation process.

Consequences of Misbeliefs

The discussion moves from descriptive findings to the potential consequences of these misbeliefs. The myth that “we only use 10% of our brain” can be attractive because of its implication of untapped potential. However, holding such a belief could influence personal choices and policy preferences in ways that misalign with scientific evidence. For example, people might pursue unproven interventions or misinterpret their own cognitive limitations as evidence of latent capabilities that can be unlocked by misguided means. On a societal level, widespread misperceptions could alter education policy, public discourse on health, and science communication strategies. The researchers emphasize that the stakes are not merely about individual beliefs but about how those beliefs shape decision making at personal, institutional, and policy levels.

Pedagogical Implications for Psychology Educators

Educators should actively integrate debunking strategies into the curriculum, rather than treating them as ancillary content. The host and Dr. Smith discuss the importance of moving beyond simply telling students what is wrong; instead, teachers should guide students through a process of hypothesis testing and evidence evaluation. Active engagement is recommended; memory research suggests that self generated memory connections help information stick better than passive reception. The discussion includes innovative classroom exercises such as having students evaluate the credibility of AI outputs about psychology topics and then consult primary literature to validate or challenge AI claims. The CRAAP test is highlighted as a simple, practical framework for evaluating information in a post truth era, encouraging readers and students to consider credibility, reliability, authority, accuracy, and purpose when evaluating sources. The conversation also notes the necessity of balancing correction with humility: while some misconceptions must be corrected, the scientific process remains iterative, and learners should be taught to adjust their beliefs as better evidence becomes available.

Better Ways to Debunk Myths

The speakers propose approaches that are feasible within time constraints in introductory courses. These include actively engaging students in debunking through guided reasoning, self generated connections, and opportunities to critique and refine their own beliefs. Another promising avenue is the use of AI tools as a training ground for evaluating information: students can compare AI's outputs with peer reviewed research to identify gaps or misinterpretations, learning to interrogate automated claims critically. The conversation also stresses that the aim is not to produce cynics who reject science, but to cultivate scientific literacy characterized by humility, nuance, cautious generalizations, and readiness to revise beliefs in light of new evidence.

Future Research and Public Engagement

Looking ahead, the researchers plan to extend the study to other stages of education, including graduate programs, and to explore cross disciplinary transfers and whether misperceptions influence actual study and behavior. They also plan to analyze how increasing exposure to psychology courses across the undergraduate curriculum affects the prevalence of misconceptions. The ultimate goal is to determine the mechanisms by which misconceptions arise, persist, and influence behavior, and to design interventions that reduce the spread of myths while supporting robust critical thinking and scientific reasoning in students and the broader public.

Concluding Reflections

The podcast closes with a call for educators and the public to engage more thoughtfully with information about psychology, encouraging curiosity, humility, and careful evaluation of sources. The discussion underscores the importance of not demonizing learners who hold misconceptions, but rather acknowledging them as an opportunity to practice scientific reasoning and to cultivate healthier information ecosystems through deliberate, evidence based education practices.
