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.
Also notable about this brazen show of might is that the missiles traveled through two countries, Iran and Iraq, before hitting their 11 targets in Syria. This means that both countries either gave their permission or simply didn’t confront Putin about the use of their airspace on his birthday.
A new report details a black market in nuclear materials.
On Wednesday, the Associated Press published a horrifying report about criminal networks in the former Soviet Union trying to sell “radioactive material to Middle Eastern extremists.” At the center of these cases, of which the AP learned of four in the past five years, was a “thriving black market in nuclear materials” in a “tiny and impoverished Eastern European country”: Moldova.
It’s a new iteration of an old problem with a familiar geography. The breakup of the Soviet Union left a superpower’s worth of nuclear weapons scattered across several countries without a superpower’s capacity to keep track of them. When Harvard’s Graham Allison flagged this problem in 1996, he wrote that the collapse of Russia’s “command-and-control society” left nothing secure. To wit:
Somewhere in Europe, a man who goes by the name “Mikro” spends his days and nights targeting Islamic State supporters on Twitter.
In August 2014, a Twitter account affiliated with Anonymous, the hacker-crusader collective, declared “full-scale cyber war” against ISIS: “Welcome to Operation Ice #ISIS, where #Anonymous will do it’s [sic] part in combating #ISIS’s influence in social media and shut them down.”
In July, I traveled to a gloomy European capital city to meet one of the “cyber warriors” behind this operation. Online, he goes by the pseudonym Mikro. He is vigilant, bordering on paranoid, about hiding his actual identity, on account of all the death threats he has received. But a few months after I initiated a relationship with him on Twitter, Mikro allowed me to visit him in the apartment he shares with his girlfriend and two Rottweilers. He works alone from his chaotic living room, using an old, battered computer—not the state-of-the-art setup I had envisaged. On an average day, he told me, he spends up to 16 hours fixed to his sofa. He starts around noon, just after he wakes up, and works late into the night and early morning.
In the name of emotional well-being, college students are increasingly demanding protection from words and ideas they don’t like. Here’s why that’s disastrous for education—and mental health.
Something strange is happening at America’s colleges and universities. A movement is arising, undirected and driven largely by students, to scrub campuses clean of words, ideas, and subjects that might cause discomfort or give offense. Last December, Jeannie Suk wrote in an online article for The New Yorker about law students asking her fellow professors at Harvard not to teach rape law—or, in one case, even use the word violate (as in “that violates the law”) lest it cause students distress. In February, Laura Kipnis, a professor at Northwestern University, wrote an essay in The Chronicle of Higher Education describing a new campus politics of sexual paranoia—and was then subjected to a long investigation after students who were offended by the article and by a tweet she’d sent filed Title IX complaints against her. In June, a professor protecting himself with a pseudonym wrote an essay for Vox describing how gingerly he now has to teach. “I’m a Liberal Professor, and My Liberal Students Terrify Me,” the headline said. A number of popular comedians, including Chris Rock, have stopped performing on college campuses (see Caitlin Flanagan’s article in this month’s issue). Jerry Seinfeld and Bill Maher have publicly condemned the oversensitivity of college students, saying too many of them can’t take a joke.
It leaves people bed-bound and drives some to suicide, but there's little research money devoted to the disease. Now, change is coming, thanks to the patients themselves.
This past July, Brian Vastag, a former science reporter, placed an op-ed with his former employer, the Washington Post. It was an open letter to the National Institutes of Health director Francis Collins, a man Vastag had formerly used as a source on his beat.
“I’ve been felled by the most forlorn of orphan illnesses,” Vastag wrote. “At 43, my productive life may well be over.”
There was no cure for his disease, known by some as chronic fatigue syndrome, Vastag wrote, and little NIH funding available to search for one. Would Collins step up and change that?
“As the leader of our nation’s medical research enterprise, you have a decision to make,” he wrote. “Do you want the NIH to be part of these solutions, or will the nation’s medical research agency continue to be part of the problem?”

“If the office is going to become a collection of employees not working together, it essentially becomes no different than a coffee shop.”
There’s plenty of research out there on the benefits of remote and flexible work. It’s been shown to lead to increased productivity, and has an undeniable benefit for work-life balance. But what does it do to everyone back at the office?
In a 2013 memo to workers explaining why the company was eliminating policies that allowed remote work, Jackie Reses, Yahoo’s head of human resources,argued that some of the “best decisions and insights come from hallway and cafeteria discussion,” and that actual presence in the office encourages better collaboration and communication.
Why Americans tend more and more to want inexperienced presidential candidates
The presidency, it’s often said, is a job for which everyone arrives unprepared. But just how unprepared is unprepared enough?
Political handicappers weigh presidential candidates’ partisanship, ideology, money, endorsements, consultants, and, of course, experience. Yet they too rarely consider an element of growing importance to voters: freshness. Increasingly, American voters view being qualified for the presidency as a disqualification.
In 2003, I announced in National Journal the 14-Year Rule. The rule was actually discovered by a presidential speechwriter named John McConnell, but because his job required him to keep his name out of print, I graciously stepped up to take credit. It is well known that to be elected president, you pretty much have to have been a governor or a U.S. senator. What McConnell had figured out was this: No one gets elected president who needs longer than 14 years to get from his or her first gubernatorial or Senate victory to either the presidency or the vice presidency.* Surprised, I scoured the history books and found that the rule works astonishingly well going back to the early 20th century, when the modern era of presidential electioneering began.
What will happen to digital collections of books, movies, and music when the tech giants fall?
When you purchase a movie from Amazon Instant Video, you’re not buying it, exactly. It’s more like renting indefinitely.
This distinction matters if your notion of “buying” is that you pay for something once and then you get to keep that thing for as long as you want. Increasingly, in the world of digital goods, a purchasing transaction isn’t that simple.
There are two key differences between buying media in a physical format versus a digital one. First, there’s the technical aspect: Maintaining long-term access to a file requires a hard copy of it—that means, for example, downloading a film, not just streaming from a third party’s server. The second distinction is a bit more complicated, and it has to do with how the law has shaped digital rights in the past 15 years. It helps to think about the experience of a person giving up CDs and using iTunes for music purchases instead.
Even in big cities like Tokyo, small children take the subway and run errands by themselves. The reason has a lot to do with group dynamics.
It’s a common sight on Japanese mass transit: Children troop through train cars, singly or in small groups, looking for seats.
They wear knee socks, polished patent-leather shoes, and plaid jumpers, with wide-brimmed hats fastened under the chin and train passes pinned to their backpacks. The kids are as young as 6 or 7, on their way to and from school, and there is nary a guardian in sight.
A popular television show called Hajimete no Otsukai, or My First Errand, features children as young as two or three being sent out to do a task for their family. As they tentatively make their way to the greengrocer or bakery, their progress is secretly filmed by a camera crew. The show has been running for more than 25 years.
