If only we would all just use our rational, scientific minds. Then we could get past our disagreements.
It’s a nice thought. Unfortunately, it’s wrong.
Yale behavioral economist Dan Kahan has spent the last decade studying whether the use of reason aggravates or reduces partisan beliefs. His research shows that aggravation easily wins. The more we use our faculties for scientific thought, the more likely we are to take a strong position that aligns with our political group. That goes for liberals as well as conservatives. [...]
Kahan’s research began as a challenge to the contention of some behavioral economists that public policy disagreements are the result of an over reliance on emotion-driven decision making—what the Nobel prize winning psychologist Daniel Kahneman calls “System 1” thinking. These researchers argued that public policy formed by experts using deliberate, analytical decision making processes (“System 2” thinking in Kahneman’s lingo) would be better and less partisan. [...]
Perhaps Kahan’s most disconcerting finding is that people with more scientific intelligence are the quickest to align themselves politically on subjects they don’t know anything about. In one experiment, Kahan analyzed how people’s opinion on a unfamiliar subject are affected when given some basic scientific information, along with details about what people in their self-identified political group tend to believe about that subject. It turned out that those with the strongest scientific reasoning skills were the ones most likely to use the information to develop partisan opinions.
