Debunking Common Psychology Myths

October 17, 2026 - 17:32

Spoiler alert: opposites do not attract. That popular belief is just one of many psychology "facts" that turn out to be myths. A closer look at the research reveals several ideas people repeat confidently that have little basis in evidence.

The idea that opposites attract is appealing because it suggests differences create chemistry. In reality, studies consistently show that people tend to pair with others who share similar values, attitudes, and backgrounds. Similarity, not contrast, predicts attraction and relationship stability.

Another widespread myth is that people only use ten percent of their brains. Brain imaging shows activity across the entire brain, and damage to almost any area produces noticeable effects. The ten percent claim has no scientific support.

The left brain versus right brain personality split is also misleading. While some functions are lateralized, people do not have a dominant hemisphere that determines whether they are logical or creative. Complex tasks recruit networks across both sides.

Learning styles are another common assumption. The belief that students learn better when taught according to their preferred style, such as visual or auditory, has been tested repeatedly without support. People may have preferences, but matching instruction to them does not improve outcomes.

Other myths include the claim that memory works like a video recorder, that venting anger reduces aggression, and that willpower is a limited resource that runs out like a battery. Research suggests memory is reconstructive, venting often increases anger, and willpower beliefs depend heavily on context.

These myths persist because they feel intuitive and are easy to repeat. Checking them against evidence is a simple way to think more clearly about human behavior.
