My father used to say that he could never argue with his mother because, “Mom had her opinions and she wouldn’t let the facts get in the way.” This article by Robert Burton on Salon.com sheds some fascinating light on the psychology of decision-making and voting. In “My Candidate, Myself,” Burton writes:

In the current presidential election, a major percentage of voters are already committed to “their candidate”; new arguments and evidence fall on deaf ears. And yet, if we, as a country, truly want change, we must be open-minded, flexible and willing to revise our opinions when new evidence warrants it. Most important, we must be able to recognize and acknowledge when we are wrong.

Unfortunately, cognitive science offers some fairly sobering observations about our ability to judge ourselves and others….

Closely allied with this unshakable self-confidence in one’s decisions is a second separate aspect of meta-cognition, the feeling of being right….

The evidence is substantial that these feelings do not correlate with the accuracy or quality of the thought….

Feelings of absolute certainty and utter conviction are not rational deliberate conclusions; they are involuntary mental sensations generated by the brain. Like other powerful mental states such as love, anger and fear, they are extraordinarily difficult to dislodge through rational arguments. Just as it’s nearly impossible to reason with someone who’s enraged and combative, refuting or diminishing one’s sense of certainty is extraordinarily difficult. Certainty is neither created by nor dispelled by reason.

To a certain extent, we all engage in individual-groupthink, to coin a new phrase. After we make our conclusions, we discount contrary evidence while overvaluing evidence that affirms our assumptions. In my opinion, last Friday’s presidential debate seemed fairly even in that neither John McCain nor Barack Obama shot himself in the foot. Similarly, neither candidate performed head and shoulders above the other. But in seeing the polls afterward, people generally thought their candidate won the debate. Now, I am leaning a certain direction and have been for months. I will say that I found myself excusing certain errors or disagreements I have with him, while I railed against his opponent when he said something I didn’t like. My mind was made up, which to a large extent is fine, so long as I remain open to new information.

So what does Burton want from a president?

I want a president aware of how his mind works, as well as what he suspects are his inborn biases and intellectual limitations. Ironically, the acknowledgment of intellectual limitations may be the best evidence for superior decision-making skills. Contrary to George Bush’s belief, we do not want certainty in the White House. We want flexibility and an acknowledgment that certainty is often a sign of ignorance.

Unfortunately, sound bites, TV interviews and presidential debates often fail to reveal the candidates’ real thought processes—how each would approach a new or complex problem for which he or she doesn’t already have a pat answer.

Burton’s article is certainly helpful in forcing us to look at our assumptions and decisions and reminding us that it takes hard work to remain open to new information and evidence. He puts a bit too much stock in cold, objective reasoning and empirical evidence as the most basic and most commonly held means of knowing whether something is true or not—I think he tends to discount spiritual phenomena. Those of the more Republican persuasion may not like the tack Burton takes in the last quarter of the piece. But Burton’s article should make us aware of our biases as we enter the home stretch of this election cycle (finally) and as we listen to our candidates and their opponents. Abraham Lincoln described our instincts well when he said, “People who like this sort of thing will find this the sort of thing they like.”
