The broad overview study, however, showed this assumption to be false:
“Contrary to a longstanding view in psychology that political conservatives are particularly prone to defensiveness and cognitive rigidity, our meta-analysis found that when partisan bias was aggregated across studies, topics, and methodological details, both liberals and conservatives were biased in favor of stimuli that confirmed their political beliefs, and to a virtually identical degree.”
But while researchers found that both groups are equally biased, they also found that certain subjects can ignite that bias more readily. Conservatives, for example, are more prone to be “biased in response to gun control arguments.” Liberals, on the other hand, are “biased toward arguments about affirmative action.”
The researchers went on to say that their study:
“[S]uggests… that partisan bias is a bipartisan problem, and that we may simply recognize bias in others better than we see it in ourselves…. This same myopia toward our own side’s biases may also help explain why a field dominated by liberal researchers has been so much more focused on the biased perceptions of the political right than the political left.”
As such a study makes perfectly clear, we’re all biased. The question is, what are we going to do with that knowledge?
