Book Review: Going to Extremes, by Cass Sunstein
Back in 2005, a trio of researchers conducted a little experiment on deliberative democracy. They assembled groups of six citizens and asked them to get together to talk about a few politically charged issues (civil unions, affirmative action, global warming). Half the groups were made up exclusively of political conservatives, and half were made up exclusively of political liberals. The result: in almost every group, the individuals took on more extreme positions after talking with the folks who already agreed with them.
Similarly, a study of judicial decision-making found three-judge panels that were all Republican rendered more conservative decisions and three-judge panels that were all Democrat rendered more liberal decisions.
The above experiment and study form the take-off point for Going to Extremes: How Like Minds Unite and Divide, by Cass R. Sunstein, a smart book (now available in paperback!) that sets forth a pithy summary of how group polarization happens. It’s an especially useful guide to the obstacles to open-minded thinking for those of us who are trying to chart a course toward a more moderate politics, and so worth understanding.
The quick takeaway point is that what matters most is information. If you only hear one side of the argument, you are likely to strengthen your convictions that the one side you hear is the correct side. And the more your convictions are strengthened, the more you are likely to seek out only that one side and disregard anyone who comes to you with alternatives. In short, a powerful reinforcing feedback loop.
“A great deal of what we believe, like, and dislike,” writes Sunstein, “is influenced by the exchange of information and by corroboration.”
Sunstein explores a number of entry points into these kinds of reinforcing cascades of corroboration. A surprisingly large number of the entry points have more to do with social instincts than anything else. Individuals defer to other individuals who are of higher status; they defer to family and friends and social groups. Most people want to be liked, and most people have an intuitive sense that a good way to be liked is to agree – or sometimes to even do those whose respect they wish to gain one better. Groups are particular prone to follow confident people – even if those confident people are wrong.
Once people start in on a particular belief path, they tend to be on the lookout for information that confirms what they already think: “Consider the well-established finding that after purchasing a product, people tend to seek out information confirming that their purchase was a sensible one.” And once caught in a cascade of confirmation, it’s hard to get out of it. Sociologists call it “homophily” – a process by which people feel more connected to that which is similar to them.
The problem, Sunstein argues (borrowing a phrase from Russell Hardin) is that most people have a “crippled epistemology” – they know very little to begin with, and if what they know supports their extremism, they have no way to know that their position is extreme.
Worse, “people often ignore powerful contrary evidence,” writes Sunstein. “When people’s false beliefs are corrected, they might become even firmer in their commitment to those beliefs.” (One famous example of this is described in Leon Festinger’s 1956 book When Prophecy Fails, about how members of a UFO cult become more resolute in its beliefs after the group leader’s prophecy that aliens from the planet Clarion would rescue cult members from an earth-destroying flood on December 21, 1954 did not come to fruition)
Sunstein worries that in the modern media environment, self-selection into different camps is easier than ever before. “Many people appear to be hearing more and louder versions of their own views, thus reducing the benefits that come from exposure to competing views and unnoticed problems…The Internet creates more dramatic ‘stratification.’”
The way out of polarization, of course, is the standard bromide of entertaining alternative viewpoints. Sunstein urges “humility and curiosity.” In fact, after reading this article, you should probably immediately go seek out a perspective you disagree with, entertain it, and let it create a slight sense of doubt in all your previous certainties.
But the truth is, you probably won’t go seek that out. Or even if you do, it’s unlikely you will come to doubt your previous ideas. One reason is that what you find will probably be written from a completely different perspective, meaning that it won’t have much to say to somebody who isn’t already a true believe from the opposite perspective.
At the very least, it is helpful to have a certain amount of self-awareness. Sunstein’s analysis of how easily and almost effortlessly one can get caught in a self-reinforcing feedback process of one-sidedness is a little bit scary. What’s remarkable is just how easily the mind closes, and how much constant work is required to fight against it. In other words: those of us who care about moderation have our work cut out for ourselves.

Like a governor issuing an 11th hour stay of execution to a death row inmate, the United Nations has intervened dramatically in the Libyan crisis. Now the world has all the authority it needs to prevent a bloodbath in Libya, and in doing so revive the faltering momentum of the Arab political awakening.

Qaddafi’s hired mercenaries are closing in on the rebel stronghold in Benghazi. If they overrun the city, two things will almost certainly happen: Any hope for a democratic Libya will die (for now), and thousands of innocent bystanders — women and children among them — will perish as Qaddafi fights to his self-proclaimed “

In a fairly predictable development, the Republican Party and the conservative movement are showing some signs of division over strategy and tactics, if not much in the way of ideological diversity. The latest indication of underlying fissures was the loss of 54 House Republicans in the vote to enact a second short-term continuing appropriations resolution.
In endorsing a no fly zone over Libya, the Arab League has taken the extraordinary step of urging western intervention in the Middle East. Nonetheless, we should resist the invitation to make America the lead actor in the Libyan drama. Our task is to help Libyans win their own freedom, not to win it for them.
Contrary to reports in the New York Times and elsewhere, high-speed rail in Florida is not yet
On the surface, Bahrain’s invitation to Saudi forces is really bad. A small but all-powerful ruling class is fearful that internal calls for democracy could reach the undesirable fervor of the masses’ brethren in Tunisia, Egypt, and in the extreme, Libya. When you dig deeper, it’s even worse: sidelined by 30 years of bankrupt policy in the Middle East, America’s relative ambiguity is providing a unique opportunity for Iran to — however absurdly — identify with its oppressed Shi’ite cousins across the Gulf.
Showing the kind of bipartisan leadership that has become all too rare these days, Senators John Kerry and Kay Bailey Hutchison have announced a new proposal to improve the way we fund infrastructure and unlock hundreds of billions in much-needed financing for new projects across the country. Their bill has one of those great acronym-friendly names that congressional staff labor to perfect: The Building and Upgrading Infrastructure for Long-Term Development Act of 2011, or for short: 





In 1999, I was a Navy F-14 pilot enforcing a no-fly zone over Southern Iraq. As I climbed into my cockpit, I was confident – confident in our mission to destroy Saddam Hussein’s brutal Republican Guard units, confident in my ability to distinguish foes from the innocent Iraqi civilians we were protecting, and confident in the legitimacy and wide support of an United Nations-backed mission.
Taking Rahm Emanuel’s advice to heart, U.S. anti-nuclear activists are using the emergency in Japan to stoke premature panic in the United States about atomic energy. While the rest of us might want to wait and see what actually happens with the Fukushima Daiichi plant before leaping to conclusions, it’s not too early to draw three conclusions that belie this fearful, “Japan Syndrome” narrative.
