Why Facts Don’t Change People’s Minds: Cognitive Dissonance

why facts dont change peoples minds

4. Ignore or deny information that conflicts with their existing beliefs. For example, “All that stuff is just ‘fake news,’ and you can’t trust it.”

The Bottom Line

When there is a conflict between our attitudes and our behavior, we tend to change our attitudes to make them consistent with our behavior rather than change our behavior to make it consistent with our attitudes.

Ideally, people would be rational beings who consistently adjust their beliefs, attitudes, and behaviors to align them with new information that is essentially incontrovertible. But that is not the case. Indeed, there are many who still maintain that the earth is flat; or only 6,500 years old; that vaccines are a health hazard; that evolution is a falsehood; or that climate change is a hoax.

Unfortunately, many people are unwilling to change their worldview to account for new information that contradicts their cherished beliefs. Instead, they reduce dissonance by justifying their outlook rather than by changing their minds or behaviors. If science worked the way many people do, we would still be living in caves and dying in our 30s. But at least the planet’s ecological health would be vastly better—even if humans’ wasn’t.

Remember: Think well, act well, feel well, be well!
