How Tribalism Overrules Reason


bigthink |  We identify ourselves as members of all sorts of tribes; our families, political parties, race, gender, social organizations. We even identify tribally just based on where we live. Go Celtics, go Red Sox, go U.S. Olympic team! One study asked people whether, if they had a fatal disease, would they prefer a life-saving diagnosis from a computer that was 1,000 miles away, or the exact same diagnosis from a computer in their town, and a large majority preferred the same information if the source…a machine…was local.

     Tribalism is pervasive, and it controls a lot of our behavior, readily overriding reason. Think of the inhuman things we do in the name of tribal unity. Wars are essentially, and often quite specifically, tribalism. Genocides are tribalism - wipe out the other group to keep our group safe – taken to madness. Racism that lets us feel that our tribe is better than theirs, parents who end contact with their own children when they dare marry someone of a different faith or color, denial of evolution or climate change or other basic scientific truths when they challenge tribal beliefs. What stunning evidence of the power of tribalism! (By the way, it wasn’t just geocentrist Catholics in the 16 adn 1700s who denied  evidence that the earth travels around the sun. Some Christian biblical literalists still do. So do a handful of ultra orthodox Jews and Muslims.)

     Yet another example is the polarized way we argue about so many issues, and the incredible irony that as we make these arguments we claim to be intelligent (smart, therefore right) yet we ignorantly close our minds to views that conflict with ours. Dan Kahan, principal researcher into the phenomenon of Cultural Cognition, has found that our views are powerfully shaped so they agree with beliefs of the groups with which we most strongly identify. His research, along with the work of others, has also found that the more challenged our views are, the more we defend them…the more dogmatic and closed-minded we become...an intellectual form of ‘circle-the-wagons, we’re under attack’ tribal unity. Talk about tribalism overruling reason.
