Neural responses can predict who your friends are, according to a Dartmouth study result. The study says friends have similar neural responses to real-world stimuli and these correspondences can be used to predict who your friends are.


The study researchers unveiled that you can predict who people are friends with based on brain patterns.

The study published Tuesday in the journal Nature Communications is the first to evaluate the relationship between people’s neural activities within a real-world social network.

For that study, Dartmouth College’s a group of brain researchers and social psychologists observed the brains of 42 students and examined their reactions as they watched some retro video clips.

The research team from the University of California, Los Angeles and Dartmouth College reported that there was a strong connection of neural similarity with a dramatically increased probability of friendship.

They added, “These results suggest that we are exceptionally similar to our friends in how we perceive and respond to the world around us.”

Lead author of the study, Carolyn Parkinson said, “Neural responses to dynamic, naturalistic stimuli, like videos, can give us a window into people’s unconstrained, spontaneous thought processes as they unfold.” Parkinson added, “Our results suggest that friends process the world around them in exceptionally similar ways.”

As a part of the study findings, the researchers also found that if you see any known person, your brain immediately tells you how important they are and their position in your social network.

The researchers also said that the detailed study is required to understand which cognitive and emotional processes underlie these effects.
