Folk psychology encompasses the intuitive beliefs and commonsense notions people naturally develop about human behavior, thoughts, and feelings. Although some of these everyday assumptions are reasonably accurate, scientific research demonstrates that many intuitive beliefs are incorrect, highlighting the necessity of a formal scientific approach to psychology.

50 Great Myths of Popular Psychology

Pop Psychology Myths

A prevalent misconception in folk psychology is that expressing anger by "letting it out"—such as screaming or punching an object—will relieve the emotion. Contrary to this commonsense belief, scientific research has demonstrated that venting anger in this manner typically leaves individuals feeling more angry rather than less.

The Catharsis Myth

A common intuitive belief is that an innocent person would never confess to a crime they did not commit unless subjected to extreme duress, such as physical torture. However, extensive empirical research contradicts this commonsense notion, revealing that false confessions are surprisingly frequent and occur for a variety of psychological and situational reasons.

The False Confessions Myth

Motivational bias is the cognitive tendency to hold onto incorrect intuitive beliefs simply because it is emotionally pleasing or comforting if they were true. People maintain these incorrect beliefs, often despite a lack of empirical evidence, because the beliefs provide hope or foster positive feelings about themselves.

Motivational Bias

Scientists cultivate an attitude of skepticism, which means pausing to consider alternatives and to search for evidence—especially systematically collected empirical evidence—when there is enough at stake to justify doing so. It does not mean being cynical, distrustful, or questioning every claim one comes across.

Scientific Skepticism

Because humans lack the natural cognitive capacity for extensive observation, memory, and complex analysis, forming perfectly accurate beliefs is nearly impossible. This cognitive limitation forces people to rely on mental shortcuts to process everyday information and form conclusions.

Cognitive Limits in Belief Formation

A common misconception in popular psychology is the belief that the majority of people go through a psychological midlife crisis during their 40s or 50s. Scientific research has shown that a normative, universal midlife crisis is a myth.

The Midlife Crisis Myth

A prevalent myth in popular psychology suggests that students learn most effectively when educational methods are tailored to their specific learning styles. Scientific studies have demonstrated that matching teaching styles to learning styles is a misconception that does not improve educational outcomes.

The Learning Styles Myth

A widely held commonsense belief is that low self-esteem is a major underlying cause of various psychological problems. However, empirical research indicates that this popular psychology myth overstates the causal role of self-esteem in mental health issues.

The Low Self-Esteem Myth

A prominent myth in popular psychology and an example of an illusory correlation is the widespread belief that the moon's phases influence human behavior, such as the idea that psychiatric admissions and crimes increase during a full moon. Extensive scientific research has consistently found no such statistical relationship, and the perception of this link is likely due to attentional bias.

The Full Moon Myth

A widely held myth of popular psychology is the incorrect belief that individuals utilize only 10% of their brain's capacity. Scientific evidence has debunked this idea, showing that humans use virtually all parts of their brain.
