A Shocker: Partisan Thought Is Unconscious
By BENEDICT CAREY
Published: January 24, 2006
Liberals and conservatives can become equally bug-eyed and irrational when talking politics, especially when they are on the defensive.
Using M.R.I. scanners, neuroscientists have now tracked what happens in the politically partisan brain when it tries to digest damning facts about favored candidates or criticisms of them. The process is almost entirely emotional and unconscious, the researchers report, and there are flares of activity in the brain's pleasure centers when unwelcome information is being rejected.
"Everything we know about cognition suggests that, when faced with a contradiction, we use the rational regions of our brain to think about it, but that was not the case here," said Dr. Drew Westen, a psychologist at Emory and lead author of the study, to be presented Saturday at meetings of the Society for Personality and Social Psychology in Palm Springs, Calif.
The results are the latest from brain imaging studies that provide a neural explanation for internal states, like infatuation or ambivalence, and a graphic trace of the brain's activity.
In 2004, the researchers recruited 30 adult men who described themselves as committed Republicans or Democrats. The men, half of them supporters of President Bush and the other half backers of Senator John Kerry, earned $50 to sit in an M.R.I. machine and consider several statements in quick succession.
The first was a quote attributed to one of the two candidates: either a remark by Mr. Bush in support of Kenneth L. Lay, the former Enron chief, before he was indicted, or a statement by Mr. Kerry that Social Security should be overhauled. Moments later, the participants read a remark that showed the candidate reversing his position. The quotes were doctored for maximum effect but presented as factual.
The Republicans in the study judged Mr. Kerry as harshly as the Democrats judged Mr. Bush. But each group let its own candidate off the hook.
After the participants read the contradictory comment, the researchers measured increased activity in several areas of the brain. They included a region involved in regulating negative emotions and another called the cingulate, which activates when the brain makes judgments about forgiveness, among other things. Also, a spike appeared in several areas known to be active when people feel relieved or rewarded. The "cold reasoning" regions of the cortex were relatively quiet.
Researchers have long known that political decisions are strongly influenced by unconscious emotional reactions, a fact routinely exploited by campaign consultants and advertisers. But the new research suggests that for partisans, political thinking is often predominantly emotional.
It is possible to override these biases, Dr. Westen said, "but you have to engage in ruthless self reflection, to say, 'All right, I know what I want to believe, but I have to be honest.' "
He added, "It speaks to the character of the discourse that this quality is rarely talked about in politics."
