Study: liberals tolerate ambiguity and conflict better than conservatives
I get nervous each time that I come across studies like these, and shy away from posting them out of fear that they oversimplify the nuanced world of electoral politics. However, this is not partisan, and for the most part objective in how it analyzes behavioral patterns. It was conducted by scientists at UCLA and New York University:
Participants were college students whose politics ranged from "veryliberal" to "very conservative." They were instructed to tap a keyboardwhen an M appeared on a computer monitor and to refrain from tappingwhen they saw a W.
M appeared four times more frequently than W, conditioning participantsto press a key in knee-jerk fashion whenever they saw a letter.
Each participant was wired to an electroencephalograph that recordedactivity in the anterior cingulate cortex, the part of the brain thatdetects conflicts between a habitual tendency (pressing a key) and amore appropriate response (not pressing the key). Liberals had morebrain activity and made fewer mistakes than conservatives when they sawa W, researchers said. Liberals and conservatives were equally accuratein recognizing M.
Researchers got the same results when they repeated the experiment inreverse, asking another set of participants to tap when a W appeared.
Frank J. Sulloway, a researcher at UC Berkeley's Institute ofPersonality and Social Research who was not connected to the study,said the results "provided an elegant demonstration that individualdifferences on a conservative-liberal dimension are strongly related tobrain activity."
Analyzing the data, Sulloway said liberals were 4.9 times as likely asconservatives to show activity in the brain circuits that deal withconflicts, and 2.2 times as likely to score in the top half of thedistribution for accuracy.
Sulloway said the results could explain why President Bush demonstrateda single-minded commitment to the Iraq war and why some peopleperceived Sen. John F. Kerry, the liberal Massachusetts Democrat whoopposed Bush in the 2004 presidential race, as a "flip-flopper" forchanging his mind about the conflict.
Based on the results, he said, liberals could be expected to more readily accept new social, scientific or religious ideas.
Accurate. Thinking things though before acting. No, let's choose a president that would be a cool guy to meet at a barbecue. What were we thinking?
