New research from London suggests we have different brain structures based on our political leanings
Last week's Congressional brinksmanship over the budget illustrated, once again, just how polarized the different camps in Congress have become. Granted, some amount of the distance between the public stances legislators took can be explained by a combination of maneuvering for votes back home and posturing for political gain in the constant power struggle that is Washington. But still. Watching the two sides argue, it was clear that they didn't just differ on details. There are entirely different worldviews behind each camp's budget proposals ... different enough that one might wonder if they're really all experiencing the same reality.
Well, according to neuroscientists in Britain ... they might not be.
In a report published last Thursday, neuroscience researchers from the Institute of Cognitive Neuroscience at University College London announced that they had found evidence that liberals and conservatives actually have different brain structures.
Cognitive neuroscientist Dr. Ryota Kanai and colleagues conducted MRI scans of 118 college students whose self-reported political views ranged from "very liberal" to "very conservative." Many areas of the subjects' brains showed no difference based on political orientation. But the subjects classifying themselves as "liberal" had a higher volume of gray matter in the anterior cingulate cortex of their brains than study participants who classified themselves as "conservative." The anterior cingulate cortex is believed to play a role in helping people cope with and sort through uncertainty and conflicting information, as well as affecting their levels of emotional awareness and empathy. The "conservative" participants, on the other hand, had a higher volume of gray matter in the right amygdala region -- which is thought to play a big role in identifying and responding to threats.
The brain is incredibly complex, of course, and we are still only in the baby stages of understanding how and why it works the way it does. But in theory, someone with a larger amygdala would very likely be quicker to see threats and feel fear, whereas someone with a smaller amygdala but larger anterior cingulate cortex, given the same stimuli, would be more likely to consider other possibilities or explanations for that stimuli. The "larger anterior cingulate cortex" group would also be more likely to look at people the first group saw as threatening and see, instead, people in need of a helping hand.
This is not the first time researchers have looked for physiological or psychological underpinnings for our political viewpoints or worldviews. In his 2009 Atlanticarticle about the longitudinal Grant Study that followed 268 Harvard students throughout their lives, Joshua Wolf Shenk reported that "personality traits assigned by the psychiatrists in the initial interviews largely predicted who would become Democrats (descriptions included 'sensitive,' 'cultural,' and 'introspective') and Republicans ('pragmatic' and 'organized)."
Indeed, Kanai said the MRI research was sparked by other recent psychological studies that found correlations between participants' functional behavior (accurately sorting through conflicting information, recognizing threats) and their stated political beliefs. In the MRI-based study, Kanai said, "We show that this functional correlate of political attitudes has a counterpart in brain structure."
But what does that mean? Are we hard-wired to disagree with each other from birth, because our brains process data from the world in fundamentally different ways? That question remains to be answered. It's possible that brain structure is set early, but it's also possible that it's influenced by experiences and environment. Kanai and his colleagues note in the report that other research efforts have already shown that brain structure "can exhibit systematic relationships with an individual's experiences and skills," and "can change after extensive training." And people certainly have been known to change their worldviews as they get older.
Clearly, Kanai and his colleagues are just scratching the surface of a very complex subject. But their research does raise some interesting questions. If experience does, in fact, influence brain structure, could a person exposed to high levels of legitimate threats over time develop a larger right amygdala to better respond to them? In other words, if you took someone who was a professed liberal and sent them to the front lines in Afghanistan for three years, would they return with a larger right amygdala, developed from an urgent need to identify and respond to threats every day? And along with that change in brain structure, would their political views shift to the right, as well? And what about children raised in a war zone? Do a great number of them end up with large right amygdalas? And, in turn, does that make them more likely to see the world in terms of threats and more absolute answers, with less tolerance for conflicting explanations or information, and less ability to feel empathy? If so, it might go a long way to explaining some of the entrenched positions in, say, the Israeli-Palestinian conflict.
Of course, that still doesn't explain people who've lived fairly secure lives but still see the world in terms of threats to be defended against, or people who've grown up in the middle of chaos and conflict and become peacemakers, overflowing with empathy and tolerance of conflicting complexity, even to a fault. What's more, few of us in mid-life see the world in as absolutely black-and-white clear terms as we did when we were 20. So another interesting follow-up would be to do a longitudinal study of brain structure over people's lifetimes, to see how those areas change. In fact, Kanai and his colleagues say as much in their report. "It requires a longitudinal study," the researchers conclude, "to determine whether the changes in brain structure that we observed lead to changes in political behavior or whether political attitudes and behavior instead result in changes of brain structure."
In any event, the University College study provides some biological proof for an important point: namely, that all of us see the world through lenses. None of us has a completely objective view of reality or truth -- a point that all of us would do well to remember. Imagine, for example, the difference in tone the debates in Congress might have if every legislator began by saying, "I recognize that I may view the same data differently than my colleagues because of the particular lenses or biases I have. But this is what I believe..."
Would it make a difference in the outcome? Possibly not. But somewhere in the recognition that our take on any given situation is not the only view, or the "right" or "obvious" or "logical" or "objective" view, but only our point of view ... lie the seeds for a more open, civil, and productive discussion.
But then, of course, that's just my point of view.
A CFPB investigation concluded that Transunion and Equifax deceived Americans about the reports they provided and the fees they charged.
In personal finance, practically everything can turn on one’s credit score. It’s both an indicator of one’s financial past, and the key to accessing necessities—without insane costs—in the future. But on Tuesday, the Consumer Financial Protection Bureau announced that two of the three major credit-reporting agencies responsible for doling out those scores—Equifax and Transunion—have been deceiving and taking advantage of Americans. The Bureau ordered the agencies to pay more than $23 million in fines and restitution.
In their investigation, the Bureau found that the two agencies had been misrepresenting the scores provided to consumers, telling them that the score reports they received were the same reports that lenders and businesses received, when, in fact, they were not. The investigation also found problems with the way the agencies advertised their products, using promotions that suggested that their credit reports were either free or cost only $1. According to the CFPB the agencies did not properly disclose that after a trial of seven to 30 days, individuals would be enrolled in a full-price subscription, which could total $16 or more per month. The Bureau also found Equifax to be in violation of the Fair Credit Reporting Act, which states that the agencies must provide one free report every 12 months made available at a central site. Before viewing their free report, consumers were forced to view advertisements for Equifax, which is prohibited by law.
In 1985, Neil Postman observed an America imprisoned by its own need for amusement. He was, it turns out, extremely prescient.
Earlier this month, thousands of protesters gathered at Washington’s National Mall to advocate for an assortment of causes: action against global climate change, federal funding for scientific research, a generally empirical approach to the world and its mysteries. The protesters at the March for Science, as scientists are wont to do, followed what has become one of the established formulas for such an event, holding clever signs, wearing cheeky outfits, and attempting, overall, to carnivalize their anger. “Make the Barrier Reef Great Again,” read one sign at the March. “This is my sine,” read another. “I KNEW TO WEAR THIS,” one woman had written on the poncho she wore that soggy Saturday, “BECAUSE SCIENCE PREDICTED THE RAIN.” Three protesters, sporting sensible footwear and matching Tyrannosaurus rex costumes, waved poster boards bearing messages like “Jurassick of this shit.”
The event's impressive turnout suggests the mainstream environmental justice movement has arrived.
WASHINGTON, D.C.—On President Trump’s hundredth day in office, a flood of protesters—fearful of the more literal floods to come—deluged the nation’s capital.
Tens of thousands of people filled downtown Washington on Saturday to protest the Trump administration’s environmental agenda and the decades-long history of American inaction on climate change. Over the course of a sweltering 91-degree day, they shut down Pennsylvania Avenue, surrounded the White House in a massive sit-in, and rallied in front of the Washington Monument.
“What do we do when our communities are under attack? Stand up, fight back!” said Dallas Goldtooth, an organizer with the Indigenous Environmental Network and one of the emcees of the rally.
The MIT economist Peter Temin argues that economic inequality results in two distinct classes. And only one of them has any power.
A lot of factors have contributed to American inequality: slavery, economic policy, technological change, the power of lobbying, globalization, and so on. In their wake, what’s left?
That’s the question at the heart of a new book, The Vanishing Middle Class: Prejudice and Power in a Dual Economy, by Peter Temin, an economist from MIT. Temin argues that, following decades of growing inequality, America is now left with what is more or less a two-class system: One small, predominantly white upper class that wields a disproportionate share of money, power, and political influence and a much larger, minority-heavy (but still mostly white) lower class that is all too frequently subject to the first group’s whims.
American society increasingly mistakes intelligence for human worth.
As recently as the 1950s, possessing only middling intelligence was not likely to severely limit your life’s trajectory. IQ wasn’t a big factor in whom you married, where you lived, or what others thought of you. The qualifications for a good job, whether on an assembly line or behind a desk, mostly revolved around integrity, work ethic, and a knack for getting along—bosses didn’t routinely expect college degrees, much less ask to see SAT scores. As one account of the era put it, hiring decisions were “based on a candidate having a critical skill or two and on soft factors such as eagerness, appearance, family background, and physical characteristics.”
The 2010s, in contrast, are a terrible time to not be brainy. Those who consider themselves bright openly mock others for being less so. Even in this age of rampant concern over microaggressions and victimization, we maintain open season on the nonsmart. People who’d swerve off a cliff rather than use a pejorative for race, religion, physical appearance, or disability are all too happy to drop the s‑bomb: Indeed, degrading others for being “stupid” has become nearly automatic in all forms of disagreement.
The party appears to be struggling to convince the public it represents a better alternative to President Trump and the GOP.
If Democrats want to regain the power they’ve lost at the state and federal level in recent years, they will have to convince more voters they can offer solutions to their problems.
That may be especially difficult, however, if voters think the party and its representatives in government don’t understand or care about them. And according to a recently released poll, many voters may, in fact, feel that way. The Washington Post-ABC News survey, released this week, found that a majority of the public thinks the Democratic Party is out of touch with the concerns of average Americans in the United States. More Americans think Democrats are out of touch than believe the same of the Republican Party or President Trump.
Jill Filipovic’s new book, The H-Spot, argues for a movement that de-emphasizes women’s equality—and focuses instead on their fulfillment.
Earlier this month, the New York Times ran an article on its website titled “How to Be Mindful While Cleaning the Bathroom.” The piece, part of the paper’s Meditation for Real Life series, offers advice on transforming that most thankless of chores into a spiritually rewarding activity, from the beginning (“once you’ve selected your cleaning tool, take a moment to notice it with your various senses”) and throughout the process (“maintain your focus on each circular, left-to-right or up-and-down motion”). The point of the exercise is not so much a clean bathroom—“you’re not chasing a result”—as it is an embrace of the notion that even toilet-scrubbing, when gone about in the right way, can produce its own soft satisfactions. “With the practice of mindful cleaning,” the piece notes, “you can transform this once boring activity into a nourishing and enjoyable moment to yourself.”
“Somewhere at Google there is a database containing 25 million books and nobody is allowed to read them.”
You were going to get one-click access to the full text of nearly every book that’s ever been published. Books still in print you’d have to pay for, but everything else—a collection slated to grow larger than the holdings at the Library of Congress, Harvard, the University of Michigan, at any of the great national libraries of Europe—would have been available for free at terminals that were going to be placed in every local library that wanted one.
At the terminal you were going to be able to search tens of millions of books and read every page of any book you found. You’d be able to highlight passages and make annotations and share them; for the first time, you’d be able to pinpoint an idea somewhere inside the vastness of the printed record, and send somebody straight to it with a link. Books would become as instantly available, searchable, copy-pasteable—as alive in the digital world—as web pages.
In the age of the digital hermit, a psychologist explains what it means to avoid other people—and what to do about it.
People today might not actually be avoiding social interaction any more than they did in past decades, but they’re certainly more vocal about it. The rise of digital communication seems to be spawning a nation of indoor cats, all humble-bragging about how introverted they are and ordering their rides and groceries without ever talking to a human.
Sometimes reclusiveness can be a sign of something more serious, though. Social anxiety is one of the most common mental illnesses, but it’s still poorly understood outside of scientific circles. The good news is that it’s highly treatable, according to Stefan G. Hofmann, the director of the Social Anxiety Program at Boston University.
I recently talked with Hofmann about how social anxiety works and what people who feel socially anxious can do about it. An edited transcript of our conversation follows.
As the death toll in the Philippines soars, those left behind confront a different life.
MANILA—On the morning of September 19, 18-year-old Brent Michael Bravo was on his way home from Manila’s Pasay City Hall, where he was being tried for illegal drug possession. He flagged down a motorized rickshaw, driven by 27-year-old Marvin Columbino. Bravo sat behind Columbino, so that his girlfriend and his grandmother, who had accompanied him that morning, could sit in the motorcycle’s side carriage. As they rounded the corner of city hall, a motorcycle, its driver wearing a bonnet and sunglasses, pulled up next to them. Suddenly, he raised a gun and opened fire, shooting at the rickshaw five times at close range. One bullet hit Bravo’s left arm and body, exiting through his right side and embedding itself in Columbino’s spinal chord. According to police reports, Bravo was the target of the attack.
