Contradictory information can reinforce existing beliefs instead of challenging them.

The Backfire Effect refers to the psychological phenomenon where presenting people with evidence that contradicts their existing beliefs actually strengthens those beliefs, rather than changing them. This can be particularly prevalent in situations where beliefs are deeply held or emotionally charged.
