All Evidence to the Contrary

More

north pole 2.JPGOne hundred years ago this month, two intrepid explorers returned from the Arctic reaches and declared that they had reached the North Pole. Not together, but on competing expeditions to become the first person and team to the Pole. Robert E. Peary led one expedition, and Frederick A. Cook led the other. And each declared the other's claim to the Pole untrue. 


Today, of course, that kind of controversy could be settled far more easily. At the very least, we would expect a GPS track record showing that the Pole had been reached, and airborne photographs or other corroborating evidence might be required, as well. Without that technology, however, the claims were a little harder to confirm. It's not like there was an exact marker at the spot, because nobody had been there before. And unlike the peak of Mt. Everest, the landscape at the precise location of the North Pole doesn't look distinctly different from the rest of the terrain--for hundreds of miles in any given direction.  

Peary.JPGSo the controversy has raged for a full century. But here's the interesting part. As more data about the expeditions, and about the North Pole, have emerged, it seems more and more likely that neither man actually reached the Pole. As John Tierney wrote recently in the Science Times, Peary supposedly took no celestial navigation readings on his final push to the Pole, until one day he took a single reading, looked very disappointed, and then declared that the observation--which he showed to no one--confirmed that he'd arrived at the North Pole, exactly. Cook had neither a trained celestial navigator nor the skill to make the observations himself. Without that skill, how on earth (so to speak) could he have reached the Pole, or known precisely when he was there? The modern-day consensus, according to Tierney, is that Peary got closer than Cook, but that neither man got closer than perhaps 100 miles away. 

Cook.JPGYet a full century and much more advanced data analysis and evidence later, Peary and Cook still have ardent supporters who adamantly believe that their hero told the truth. They suggest that it might have been possible for either explorer to have found the Pole without clear celestial sightings, by studying wind patterns in the snow, or observing shadows, or even by compass, even though a compass needle gets extremely erratic near the Earth's poles. Apparently, some of the Peary/Cook advocates are more comfortable with contorted logic than simply acknowledging that, given more data, it appears their initial impression of things was ... ummm ... wrong. 

Peary and Cook are not the only explorers to have die-hard believers who have clung to a set vision of their heroes' lives despite the emergence of countering evidence. David Roberts, an editor at National Geographic Adventure, encountered a startling backlash of anger and even threats after writing a feature article last spring (which he's expanded into a soon-to-be-released book) that solved the mystery of a young adventurer's disappearance--but not the way some of the adventurer's admirers wanted it solved. 

In 1934, at the age of 20, Everett Reuss left civilization to go live in the wilderness ... and was never heard from again. A whole folk myth movement sprang up around this young man who seemed to have slipped so completely into the wild that he eluded discovery for the rest of his life. An annual art festival in Escalante, Utah, is even named in his honor. But Roberts, who researched the case for 10 years, finally discovered evidence that Ruess had been murdered by two members of the Ute tribe almost as soon as he'd begun his journey. There was a witness to the murder, an unearthed skeleton, and DNA tests that were compatible with other family members. 

The mystery, it seemed, had been solved. But the hue and cry surrounding Roberts' piece was both angry and loud, catching both Roberts and the Reuss family by surprise. "We all want our heroes to succeed," Reuss' nephew Brian surmised, in an attempt to explain the uproar. (A couple months ago, I wrote a longer essay about the Reuss controversy.)

Perhaps. But I now think there's more to the equation; tendencies that affect how we view information about not just heroes and adventurers, but also issues and events that affect local and national policy and action. 

How is it that people can cling to an opinion or view of a person, event, issue of the world, despite being presented with clear or mounting data that contradicts that position? The easy answer, of course, is simply that people are irrational. But a closer look at some of the particular ways and reasons we're irrational offers some interesting food for thought.

In a recently published study, a group of researchers from Northwestern University, UNC Chapel HIll, SUNY Buffalo and Millsaps College found that people often employ an approach the researchers called "motivated reasoning" when sorting through new information or arguments, especially on controversial issues. Motivated reasoning is, as UCLA public policy professor Mark Kleiman put it, the equivalent of policy-driven data, instead of data-driven policy.

In other words, if people start with a particular opinion or view on a subject, any counter-evidence can create "cognitive dissonance"--discomfort caused by the presence of two irreconcilable ideas in the mind at once. One way of resolving the dissonance would be to change or alter the originally held opinion. But the researchers found that many people instead choose to change the conflicting evidence--selectively seeking out information or arguments that support their position while arguing around or ignoring any opposing evidence, even if that means using questionable or contorted logic. 

That's not a news flash to anyone who's paid attention to any recent national debate--although the researchers pointed out that this finding, itself, runs counter to the idea that the reason people continue to hold positions counter to all evidence is because of misinformation or lack of access to the correct data. Even when presented with compelling, factual data from sources they trusted, many of the subjects still found ways to dismiss it. But the most interesting (or disturbing) aspect of the Northwestern study was the finding that providing additional counter-evidence, facts, or arguments actually intensified this reaction. Additional countering data, it seems, increases the cognitive dissonance, and therefore the need for subjects to alleviate that discomfort by retreating into more rigidly selective hearing and entrenched positions. 

Needless to say, these findings do not bode well for anyone with hopes of changing anyone else's mind with facts or rational discussion, especially on "hot button" issues. But why do we cling so fiercely to positions when they don't even involve us directly? Why do we care who got to the North Pole first? Or whether a particular bill has provision X versus provision Y in it? Why don't we care more about simply finding out the truth--especially in cases where one "right" answer actually exists?

Part of the reason, according to Kleiman, is "the brute fact that people identify their opinions with themselves; to admit having been wrong is to have lost the argument, and (as Vince Lombardi said), every time you lose, you die a little." And, he adds, "there is no more destructive force in human affairs--not greed, not hatred--than the desire to have been right."

So, what do we do about that? If overcoming "the desire to have been right" is half as challenging as overcoming hate or greed, the outlook doesn't seem promising. But Kleiman, who specializes in crime control policy and alternative solutions to very sticky problems (his latest book is "When Brute Force Fails: How to Have Less Crime and Less Punishment"), thinks all is not lost. He points to the philosopher Karl Popper, who, he says, believed fiercely in the discipline and teaching of critical thinking, because "it allows us to offer up our opinions as a sacrifice, so that they die in our stead."

A liberal education, Kleiman says, "ought, above all, to be an education in non-attachment to one's current opinions. I would define a true intellectual as one who cares terribly about being right, and not at all about having been right." Easy to say, very hard to achieve. For all sorts of reasons. But it's worth thinking about. Even if it came at the cost of sacrificing or altering our most dearly-held opinions ... the truth might set us free.
