"The brain treats questions about beliefs like physical threats. Can we learn to disarm it?"
From a recent article with the above title:
Jonas Kaplan is an assistant research professor of psychology at USC’s Brain and Creativity Institute. He studies the human brain using fMRIs to observe how it responds to, among other stimuli, challenges to predisposed beliefs.Can we learn to disarm it? The answer is Yes!
In a study that he and his research team published in Scientific Reports last year, they studied the scans of people undergoing simultaneous questioning, and demonstrated the physical effects that take place within the brain during periods when political beliefs were questioned.
The study uncovered a correlation: when a belief is directly challenged by new information, parts of the brain that typically show activity for physical threats expressed greater activity in people who tended to be more resistive to changing their minds.
“The brain can be thought of as a very sophisticated self-defense machine,” Kaplan told me. “If there is a belief that the brain considers part of who we are, it turns on its self-defense mode to protect that belief.”
Kaplan argues that this demonstrates that the brain reacts to belief challenges in the same way that it reacts to perceived physical threats. This would help explain why minds are so resistant to change the beliefs that form one’s perception of reality.
