Why so many minds think alike
Thursday, January 15th, 2009You’re in a room with 10 other people who seem to agree on something, but you hold the opposite view. Do you say something? Or do you just go along with the others?
Imaging techniques help scientists look at the basis for principles of social psychology in the brain.
Decades of research show people tend to go along with the majority view, even if that view is objectively incorrect. Now, scientists are supporting those theories with brain images.
A new study in the journal Neuron shows when people hold an opinion differing from others in a group, their brains produce an error signal. A zone of the brain popularly called the “oops area” becomes extra active, while the “reward area” slows down, making us think we are too different.
“We show that a deviation from the group opinion is regarded by the brain as a punishment,” said Vasily Klucharev, postdoctoral fellow at the F.C. Donders Centre for Cognitive Neuroimaging in the Netherlands and lead author of the study.
