A Flight From Reason? A Nudge-ocracy? Post-Rational Thinking Supports Neither

Thomas Nagel says that "devaluation of conscious reasoning" is a form of "moral and intellectual laziness," and that David Brooks is guilty of same in his new book. Nagel's review made me wonder if others among us partisans of post-rational research should feel tarred by this brush too. Maybe in my enthusiasm for research into the non-conscious, inconsistent and inconstant drivers of behavior, I'm making a case against reason which does more harm than good.


What Nagel meant by "conscious reasoning" is, I think, a set of tools, invented over centuries, for reducing ignorance and avoiding errors. "Conscious reasoning" includes mathematics, logic and the sciences—enterprises in which statements are subject to explicit tests for accuracy and consistency, and the tests themselves are also constantly tested for adherence to consistent principles. These rigorous methods are supposed to be unaffected by emotions, social relationships or other aspects of our largely unconscious psychology.

There are people who claim that these tools are over-rated, misguided, ungodly or inhuman. I don't think the researchers who turn up in this blog are guilty of this. They respect the tools of reason (they use them to do their research, after all). They just keep in mind, though, that a tool is not a model. The human mind invented reason, but that doesn't mean the mind is shaped like its invention. Pointing out the differences between my mind and my computer doesn't imply disdain for the computer's admirable powers, nor does it commit me to throwing the computer away.

What worries me about some post-rationalist ideas is not the imaginary danger of a Cult of Unreason but the real danger of anti-democratic elitism. Maybe it's an occupational hazard: Contemplating irrationality in human affairs leads easily to the notion that "they," the unenlightened, are lost in their self-made darkness while "we," who have seen the light, know better. With that attitude, behavioral research looks less like an open-ended quest for understanding and more like a cookbook full of recipes for manipulation.

To the supposedly enlightened, this is easy to miss. Of course people should donate their organs, recycle and save for retirement! What could be wrong with wanting to correct the mind's natural "mistakes"? As the United Kingdom's government coalition declared last year, "Our Government will be a much smarter one, shunning the bureaucratic levers of the past and finding intelligent ways to encourage, support and enable people to make better choices for themselves."

British newspapers (The Guardian here and The Independent here) reported this winter that this declaration led to the creation of a "Behavioral Insight Team" whose goal is to tweak and trim government regulations to help people do the right thing. That is the strategy recommended by Cass Sunstein and Richard Thaler in Nudge. Yet one person's bagful of "nudge" is another's set of "psychological tricks to alter our behavior," as The Independent put it last January.

Behavioral economists often use homey metaphors of self-control (you know you shouldn't eat that brownie, you know you should buy a car that fits your dad-needs and not your cool-guy fantasies, let's help you). But the metaphor breaks down when controller and controlled are literally two different people. Refusing to acknowledge this makes a policy discussion of irrationality into a conversation about pension options and checkboxes on drivers' licenses. Which is tantamount to saying there is only one right way to behave and we policy-makers know what it is. Dissent is irrational, but don't worry, we'll fix it.

Nagel has noticed that this is a values problem, and that you can't marry post-rational research to policy without confronting it. Of Brooks' book, he observes:

Still, even if empirical methods enable us to understand subrational processes better, the crucial question is, How are we to use this kind of self-understanding? Brooks emphasizes the ways in which it can improve our prediction and control of what people will do, but I am asking something different. When we discover an unacknowledged influence on our conduct, what should be our critical response?

One possible response is that we all want, or should want, the same things, consistently, so let's bring on the nudges. That is, I think, what a lot of recent behavioral economics books are claiming, and what Thaler believes. Last year he called worries about elite paternalism "nudgephobia" and likened them to "the fear of being given helpful directions when lost" or "the fear of obtaining reliable medical advice when sick."

I think Nagel's response to Brooks might prove wiser. Post-rational research isn't a cookbook of administrative tweaks; it's a challenge to our notions of what people are, and how they should live with their human nature. Only that broader conversation offers a chance to transform society for the better.

How a huge, underwater wall could save melting Antarctic glaciers

Scientists think constructing a miles-long wall along an ice shelf in Antarctica could help protect the world's largest glacier from melting.

Surprising Science
  • Rising ocean levels are a serious threat to coastal regions around the globe.
  • Scientists have proposed large-scale geoengineering projects that would prevent ice shelves from melting.
  • The most successful solution proposed would be a miles-long, incredibly tall underwater wall at the edge of the ice shelves.

The world's oceans will rise significantly over the next century if the massive ice shelves connected to Antarctica begin to fail as a result of global warming.

To prevent or hold off such a catastrophe, a team of scientists recently proposed a radical plan: build underwater walls that would either support the ice or protect it from warm waters.

In a paper published in The Cryosphere, Michael Wolovick and John Moore from Princeton and the Beijing Normal University, respectively, outlined several "targeted geoengineering" solutions that could help prevent the melting of western Antarctica's Florida-sized Thwaites Glacier, whose melting waters are projected to be the largest source of sea-level rise in the foreseeable future.

An "unthinkable" engineering project

"If [glacial geoengineering] works there then we would expect it to work on less challenging glaciers as well," the authors wrote in the study.

One approach involves using sand or gravel to build artificial mounds on the seafloor that would help support the glacier and hopefully allow it to regrow. In another strategy, an underwater wall would be built to prevent warm waters from eating away at the glacier's base.

The most effective design, according to the team's computer simulations, would be a miles-long and very tall wall, or "artificial sill," that serves as a "continuous barrier" across the length of the glacier, providing it both physical support and protection from warm waters. Although the study authors suggested this option is currently beyond any engineering feat humans have attempted, it was shown to be the most effective solution in preventing the glacier from collapsing.

Source: Wolovick et al.

An example of the proposed geoengineering project. By blocking off the warm water that would otherwise eat away at the glacier's base, further sea level rise might be preventable.

But other, more feasible options could also be effective. For example, building a smaller wall that blocks about 50% of warm water from reaching the glacier would have about a 70% chance of preventing a runaway collapse, while constructing a series of isolated, 1,000-foot-tall columns on the seafloor as supports had about a 30% chance of success.

Still, the authors note that the frigid waters of the Antarctica present unprecedently challenging conditions for such an ambitious geoengineering project. They were also sure to caution that their encouraging results shouldn't be seen as reasons to neglect other measures that would cut global emissions or otherwise combat climate change.

"There are dishonest elements of society that will try to use our research to argue against the necessity of emissions' reductions. Our research does not in any way support that interpretation," they wrote.

"The more carbon we emit, the less likely it becomes that the ice sheets will survive in the long term at anything close to their present volume."

A 2015 report from the National Academies of Sciences, Engineering, and Medicine illustrates the potentially devastating effects of ice-shelf melting in western Antarctica.

"As the oceans and atmosphere warm, melting of ice shelves in key areas around the edges of the Antarctic ice sheet could trigger a runaway collapse process known as Marine Ice Sheet Instability. If this were to occur, the collapse of the West Antarctic Ice Sheet (WAIS) could potentially contribute 2 to 4 meters (6.5 to 13 feet) of global sea level rise within just a few centuries."

Why the worst part about climate change isn't rising temperatures

The world's getting hotter, and it's getting more volatile. We need to start thinking about how climate change encourages conflict.

  • Climate change is usually discussed in terms of how it impacts the weather, but this fails to emphasize how climate change is a "threat multiplier."
  • As a threat multiplier, climate change makes already dangerous social and political situations even worse.
  • Not only do we have to work to minimize the impact of climate change on our environment, but we also have to deal with how it affects human issues today.

Human beings are great at responding to imminent and visible threats. Climate change, while dire, is almost entirely the opposite: it's slow, it's pervasive, it's vague, and it's invisible. Researchers and policymakers have been trying to package climate change in a way that conveys its severity. Usually, they do so by talking about its immediate effects: rising temperature, rising sea levels, and increasingly dangerous weather.

These things are bad, make no mistake about it. But the thing that makes climate change truly dire isn't that Cape Cod will be underwater next century, that polar bears will go extinct, or that we'll have to invent new categories for future hurricanes. It's the thousands of ancillary effects — the indirect pressure that climate change puts on every person on the planet.

How a drought in the Middle East contributed to extremism in Europe

Because climate change is too big for the mind to grasp, we'll have to use a case study to talk about this. The Syrian civil war is a horrific tangle of senseless violence, but there are some primary causes we can point to. There is the longstanding conflicts between different religious sects in that country. Additionally, the Arab Spring swept Syria up in a wave of resistance against authoritarian leaders in the Middle East — unfortunately, Syrian protests were brutally squashed by Bashar Al-Assad. These, and many other factors, contributed to the start of the Syrian civil war.

One of these other factors was drought. In fact, the drought in that region — it started in 2006 — has been described as the "worst long-term drought and most severe set of crop failures since agricultural civilization began in the Fertile Crescent many millennia ago." Because of this drought, many rural Syrians could no longer support themselves. Between 2006 and 2009, an estimated 1.5 million Syrians — many of them agricultural workers and farmers — moved into the country's major cities. With this sudden mixing of different social groups in a country where classes and religious sects were already at odds with one another, tensions rose, and the increased economic instability encouraged chaos. Again, the drought didn't cause the civil war — but it sure as hell helped it along.

The ensuing flood of refugees to Europe is already a well-known story. The immigration crisis was used as a talking point in the Brexit movement to encourage Britain to leave the EU. Authoritarian or extreme-right governments and political parties have sprung up in France, Italy, Greece, Hungary, Slovenia, and other European countries, all of which have capitalized on fears of the immigration crisis.

Why climate change is a "threat multiplier"

This is why both NATO and the Pentagon have labeled climate change as a "threat multiplier." On its own, climate change doesn't cause these issues — rather, it exacerbates underlying problems in societies around the world. Think of having a heated discussion inside a slowly heating-up car.

Climate change is often discussed in terms of its domino effect: for example, higher temperatures around the world melt the icecaps, releasing methane stored in the polar ice that contributes to the rise in temperature, which both reduces available land for agriculture due to drought and makes parts of the ocean uninhabitable for different animal species, wreaking havoc on the food chain, and ultimately making food more scarce.

Maybe we should start to consider climate change's domino effect in more human and political terms. That is, in terms of the dominoes of sociopolitical events spurred on by climate change and the missing resources it gobbles up.

What the future may hold

Increasingly severe weather events will make it more difficult for nations to avoid conflict.

Part of why this is difficult to see is because climate change does not affect all countries proportionally — at least, not in a direct sense. Germanwatch, a German NGO, releases a climate change index every year to analyze exactly how badly different countries have been affected by climate change. The top five most at-risk countries are Haiti, Zimbabwe, Fiji, Sri Lanka, and Vietnam. Notice that many of these places are islands, which are at the greatest risk for major storms and rising sea levels. Some island nations are even expected to literally disappear — the leaders of these nations are actively making plans to move their citizens to other countries.

But Germanwatch's climate change index is based on weather events. It does not account for the political and social instability that will likely result. The U.S. and many parts of Europe are relatively low on the index, but that is precisely why these countries will most likely need to deal with the human cost of climate change. Refugees won't go from the frying pan into the fire: they'll go to the closest, safest place available.

Many people's instinctive response to floods of immigrants is to simply make borders more restrictive. This makes sense — a nation's first duty is to its own citizens, after all. Unfortunately, people who support stronger immigration policies tend to have right-wing authoritarian tendencies. This isn't always the case, of course, but anecdotally, we can look at the governments in Europe that have stricter immigration policies. Hungary, for example, has extremely strict policies against Muslim immigrants. It's also rapidly turning into a dictatorship. The country has cracked down on media organizations and NGOs, eroded its judicial system's independence, illegalized homelessness, and banned gender studies courses.

Climate change and its sociopolitical effects, such as refugee migration, aren't some poorer country's problem. It's everyone's problem. Whether it's our food, our homes, or our rights, climate change will exact a toll on every nation on Earth. Stopping climate change, or at least reducing its impact, is vitally important. Equally important is contending with the multifaceted threats its going to throw our way.
