Undecideds Are Smarter Than You

Not really. But in spite of the assertions by those who have decided that it's a clear choice, and anyone who hasn't decided between Obama and McCain is an idiot, here's support from the scientific community that we're acting in an intelligent manner. Below is an excerpt from an NYT op-ed on the subject. To read the whole piece follow the link.

AS we enter the final week of a seemingly endless election campaign, opinion polls continue to identify a substantial fraction of voters who consider themselves “undecided.” Although their numbers are dwindling, they could still determine the outcome of the race in some states. Comedians and other commentators have portrayed these people as fools, unable to choose even when confronted with the starkest of contrasts.

Recent research in neuroscience and psychology, however, suggests that most undecided voters may be smarter than you think. They’re not indifferent or unable to make clear comparisons between the candidates. They may be more willing than others to take their time — or else just unaware that they have essentially already made a choice.

Neuroscientists have begun to tease out the brain systems that make decisions. Even when it takes no more than a second, decision-making is thought to involve two parts, gathering evidence and committing to a choice. In tasks as simple as deciding whether a shifting pattern of dots is moving to the left or to the right, brain activity in the parietal cortex rises as evidence is gathered, eventually reaching a tipping point (though it’s not yet known which brain regions drive the final choice).

Inherent to this process is a trade-off between speed and accuracy. Commit early and you can get on with your life. Take more time and you might make a wiser or more accurate decision. Since a commitment to John McCain or Barack Obama is not required until Nov. 4, for the greatest accuracy, one should gather evidence until that date. So then why aren’t there even more undecided voters? In measurements of decision-related neural activity, after there is enough evidence to reach a person’s decision threshold, his brain can ignore further input even when it might improve accuracy. The brain goes ahead and decides, freeing up mental resources to deal with other problems.
