A rather depressing NYT Op-Ed from David Brooks about how partisanship blinds everyone, regardless of party.
Moreover, Green, Palmquist and Schickler continue, people do not choose parties by comparing platforms and then figuring out where the nation’s interests lie. Drawing on a vast range of data, these political scientists argue that party attachment is more like attachment to a religious denomination or a social club. People have stereotypes in their heads about what Democrats are like and what Republicans are like, and they gravitate toward the party made up of people like themselves.
Once they have formed an affiliation, people bend their philosophies and their perceptions of reality so they become more and more aligned with members of their political tribe.
Which perceptions lead to misperceptions that can influence rational decisionmaking.
For example, the Princeton political scientist Larry Bartels has pointed to survey data collected after the Reagan and Clinton presidencies. In 1988, voters were asked if they thought the nation’s inflation rate had fallen during the Reagan presidency.
In fact, it did. The inflation rate fell from 13.5 percent to 4.1 percent. But only 8 percent of strong Democrats said the rate had fallen. Fifty percent of partisan Democrats believed that inflation had risen under Reagan. Strong Republicans had a much sunnier and more accurate impression of economic trends. Forty-seven percent said inflation had declined.
Then, at the end of the Clinton presidency, voters were asked similar questions about how the country had fared in the previous eight years. This time, it was Republicans who were inaccurate and negative. Democrats were much more positive. Bartels concludes that partisan loyalties have a pervasive influence on how people see the world. They reinforce and exaggerate differences of opinion between Republicans and Democrats.
Getting back to earlier posts on media bias, is it a matter of biased (left or right) media outlets distorting public opinion, or folks gravitating to media outlets (left or right) that reinforce the opinions they find cognitively comfortable?
A more disturbing question is, if folks shape their opinions to the group they choose to be with, how does that affect basic democratic principles of individual decision-making and personal responsibility?
