A specific cluster of neurons in the hippocampus acts as a belief stabilizer that blocks the brain from learning new facts.

Resistance to change is a biological process driven by the vCA1 neurons in the ventral hippocampus. These cells actively suppress new learning even when evidence shows that a person's current belief is wrong. This neural circuit is particularly strong when the brain expects a bad outcome that never actually happens. It provides a physical explanation for why people remain stubborn in the face of contradictory facts. The brain is literally wired to preserve its existing map of the world rather than update it for accuracy.
