According to new research published in Psychological Science, having to explain how a political policy works can lead people to express less extreme attitudes toward the policy. If you think just a bit further, you will find an important role for education.

From the press release:

Psychological scientist Philip Fernbach of the Leeds School of Business at the University of Colorado, Boulder and his co-authors were interested in exploring some of the factors that could contribute to what they see as increasing political polarization in the United States.

“We wanted to know how it’s possible that people can maintain such strong positions on issues that are so complex — such as macroeconomics, health care, foreign relations — and yet seem to be so ill-informed about those issues,” says Fernbach.

Drawing on previous research on the illusion of understanding, Fernbach and colleagues speculated that one reason for the apparent paradox may be that voters think they understand how policies work better than they actually do.

In their first study, the researchers asked participants taking an online survey to rate how well they understood six political policies, including raising the retirement age for Social Security, instituting a national flat tax, and implementing merit-based pay for teachers. The participants were randomly assigned to explain two of the policies and then asked to re-rate how well they understood the policies.

As the researchers predicted, people reported lower understanding of all six policies after they had to explain them, and their positions on the policies were less extreme. In fact, the data showed that the more people’s understanding decreased, the more uncertain they were about the position, and the less extreme their position was in the end.

The act of explaining also affected participants’ behavior. People who initially held a strong position softened their position after having to explain it, making them less likely to donate bonus money to a related organization when they were given the opportunity to do so.

Importantly, the results affected people along the whole political spectrum, from self-identified Democrats to Republicans to Independents.

According to the researchers, these findings shed light on a psychological process that may help people to open the lines of communication in the context of a heated debate or negotiation.

“This research is important because political polarization is hard to combat,” says Fernbach. “There are many psychological processes that act to create greater extremism and polarization, but this is a rare case where asking people to attempt to explain makes them back off their extreme positions.”

Abstract of the research:

People often hold extreme political attitudes about complex policies. We hypothesized that people typically know less about such policies than they think they do (the illusion of explanatory depth) and that polarized attitudes are enabled by simplistic causal models. Asking people to explain policies in detail both undermined the illusion of explanatory depth and led to attitudes that were more moderate (Experiments 1 and 2). Although these effects occurred when people were asked to generate a mechanistic explanation, they did not occur when people were instead asked to enumerate reasons for their policy preferences (Experiment 2). Finally, generating mechanistic explanations reduced donations to relevant political advocacy groups (Experiment 3). The evidence suggests that people’s mistaken sense that they understand the causal processes underlying policies contributes to political polarization.
