The experimenters used functional magnetic resonance imaging (fMRI) to scan the brains of Harvard and other Boston-area students while showing them pictures of other college-age people whom the researchers randomly described as either liberal northeastern students or conservative Midwest fundamentalist Christian students.
The study concludes that the secret to getting along with someone that you perceive as an outsider is to find some common ground so that your brain will accept them as someone with similar circumstances.
This is not new advice. Yet it is heartening to see that it is firmly grounded in distinct patterns of neural activity. There may be a brain basis for reacting with prejudices for those that seem different. But there’s also a brain basis for overriding those differences and seeing outsiders as more like us.
In other words, a civilized society depends not on the people who are currently the most civilized, but those who are most willing to accept change, as social or cultural groupings change, split or coalesce. Inevitably this means reasonable people rather than faithful people.
