Choosing Friday night plans. Deciding what to wear to work. Selecting a new Netflix show to binge-watch. People are influenced by the tastes and opinions of their friends, and vice versa. But that doesn’t mean you’re a carbon copy of your social network— or does it? We talk with Carolyn Parkinson, an assistant professor of social psychology at UCLA, about why our brains might be more similar that we think.
- Sociologist Nicholas Christakis spoke with us in 2014 about his study on how an individual’s social network can impact everything from their political views to their body weight. One of the conclusions of his work is that humans typically choose friends who are as genetically similar as their 4th cousin.
- Parkinson’s study examined the brains of 300 students in the same MBA program. After doing fMRI and mapping the students’ social network, the researchers found that the closer the friendship between two students, the more similar their brain activity appeared to be.
- But Parkinson’s research on friendship poses a question about the causality of likeness. Do we seek out friends who are similar to us, or do our social connections make us more similar?
