PTSD calls for collective healing

Sebastian Junger writes: In two American studies of middle-class families during the 1980s, 85 percent of young children slept alone — a figure that rose to 95 percent among families considered “well-educated.” Northern European societies, including America, are the only ones in history to make very young children sleep alone in such numbers. The isolation is thought to trigger fears that make many children bond intensely with stuffed animals for reassurance. Only in Northern European societies do children go through the well-known developmental stage of bonding with stuffed animals; elsewhere, children get their sense of safety from the adults sleeping near them.

More broadly, in most human societies, almost nobody sleeps alone. Sleeping in family groups of one sort or another has been the norm throughout human history and is still commonplace in most of the world. Again, Northern European societies are among the few where people sleep alone or with a partner in a private room. When I was with American soldiers at a remote outpost in Afghanistan, we slept in narrow plywood huts where I could reach out and touch three other men from where I slept. They snored, they talked, they got up in the middle of the night to use the piss tubes, but we felt safe because we were in a group. The Taliban attacked the position regularly, and the most determined attacks often came at dawn. Another unit in a nearby valley was almost overrun and took 50 percent casualties in just such an attack. And yet I slept better surrounded by those noisy, snoring men than I ever did camping alone in the woods of New England.

Many soldiers will tell you that one of the hardest things about coming home is learning to sleep without the security of a group of heavily armed men around them. In that sense, being in a war zone with your platoon feels safer than being in an American suburb by yourself. I know a vet who felt so threatened at home that he would get up in the middle of the night to build fighting positions out of the living-room furniture. This is a radically different experience from what warriors in other societies go through, such as the Yanomami, of the Orinoco and Amazon Basins, who go to war with their entire age cohort and return to face, together, whatever the psychological consequences may be. As one anthropologist pointed out to me, trauma is usually a group experience, so trauma recovery should be a group experience as well. But in our society it’s not.

“Our whole approach to mental health has been hijacked by pharmaceutical logic,” I was told by Gary Barker, an anthropologist whose group, Promundo, is dedicated to understanding and preventing violence. “PTSD is a crisis of connection and disruption, not an illness that you carry within you.”

This individualizing of mental health is not just an American problem, or a veteran problem; it affects everybody. A British anthropologist named Bill West told me that the extreme poverty of the 1930s and the collective trauma of the Blitz served to unify an entire generation of English people. “I link the experience of the Blitz to voting in the Labour Party in 1945, and the establishing of the National Health Service and a strong welfare state,” he said. “Those policies were supported well into the 60s by all political parties. That kind of cultural cohesiveness, along with Christianity, was very helpful after the war. It’s an open question whether people’s problems are located in the individual. If enough people in society are sick, you have to wonder whether it isn’t actually society that’s sick.”

Ideally, we would compare hunter-gatherer society to post-industrial society to see which one copes better with PTSD. When the Sioux, Cheyenne, and Arapaho fighters returned to their camps after annihilating Custer and his regiment at Little Bighorn, for example, were they traumatized and alienated by the experience — or did they fit right back into society? There is no way to know for sure, but less direct comparisons can still illuminate how cohesiveness affects trauma. In experiments with lab rats, for example, a subject that is traumatized — but not injured — after an attack by a larger rat usually recovers within 48 hours unless it is kept in isolation, according to data published in 2005 in Neuroscience & Biobehavioral Reviews. The ones that are kept apart from other rats are the only ones that develop long-term traumatic symptoms. And a study of risk factors for PTSD in humans closely mirrored those results. In a 2000 study in the Journal of Consulting and Clinical Psychology, “lack of social support” was found to be around two times more reliable at predicting who got PTSD and who didn’t than the severity of the trauma itself. You could be mildly traumatized, in other words—on a par with, say, an ordinary rear-base deployment to Afghanistan — and experience long-term PTSD simply because of a lack of social support back home.

Anthropologist and psychiatrist Brandon Kohrt found a similar phenomenon in the villages of southern Nepal, where a civil war has been rumbling for years. Kohrt explained to me that there are two kinds of villages there: exclusively Hindu ones, which are extremely stratified, and mixed Buddhist/Hindu ones, which are far more open and cohesive. He said that child soldiers, both male and female, who go back to Hindu villages can remain traumatized for years, while those from mixed-religion villages tended to recover very quickly. “PTSD is a disorder of recovery, and if treatment only focuses on identifying symptoms, it pathologizes and alienates vets,” according to Kohrt. “But if the focus is on family and community, it puts them in a situation of collective healing.” [Continue reading…]

Each of us is, genetically, more microbial than human

The New York Times reports: Since 2007, when scientists announced plans for a Human Microbiome Project to catalog the micro-organisms living in our body, the profound appreciation for the influence of such organisms has grown rapidly with each passing year. Bacteria in the gut produce vitamins and break down our food; their presence or absence has been linked to obesity, inflammatory bowel disease and the toxic side effects of prescription drugs. Biologists now believe that much of what makes us human depends on microbial activity. The two million unique bacterial genes found in each human microbiome can make the 23,000 genes in our cells seem paltry, almost negligible, by comparison. “It has enormous implications for the sense of self,” Tom Insel, the director of the National Institute of Mental Health, told me. “We are, at least from the standpoint of DNA, more microbial than human. That’s a phenomenal insight and one that we have to take seriously when we think about human development.”

Given the extent to which bacteria are now understood to influence human physiology, it is hardly surprising that scientists have turned their attention to how bacteria might affect the brain. Micro-organisms in our gut secrete a profound number of chemicals, and researchers like [Mark] Lyte have found that among those chemicals are the same substances used by our neurons to communicate and regulate mood, like dopamine, serotonin and gamma-aminobutyric acid (GABA).

Why the modern world is bad for your brain

Daniel J Levitin writes: Our brains are busier than ever before. We’re assaulted with facts, pseudo facts, jibber-jabber, and rumour, all posing as information. Trying to figure out what you need to know and what you can ignore is exhausting. At the same time, we are all doing more. Thirty years ago, travel agents made our airline and rail reservations, salespeople helped us find what we were looking for in shops, and professional typists or secretaries helped busy people with their correspondence. Now we do most of those things ourselves. We are doing the jobs of 10 different people while still trying to keep up with our lives, our children and parents, our friends, our careers, our hobbies, and our favourite TV shows.

Our smartphones have become Swiss army knife–like appliances that include a dictionary, calculator, web browser, email, Game Boy, appointment calendar, voice recorder, guitar tuner, weather forecaster, GPS, texter, tweeter, Facebook updater, and flashlight. They’re more powerful and do more things than the most advanced computer at IBM corporate headquarters 30 years ago. And we use them all the time, part of a 21st-century mania for cramming everything we do into every single spare moment of downtime. We text while we’re walking across the street, catch up on email while standing in a queue – and while having lunch with friends, we surreptitiously check to see what our other friends are doing. At the kitchen counter, cosy and secure in our domicile, we write our shopping lists on smartphones while we are listening to that wonderfully informative podcast on urban beekeeping.

But there’s a fly in the ointment. Although we think we’re doing several things at once, multitasking, this is a powerful and diabolical illusion. Earl Miller, a neuroscientist at MIT and one of the world experts on divided attention, says that our brains are “not wired to multitask well… When people think they’re multitasking, they’re actually just switching from one task to another very rapidly. And every time they do, there’s a cognitive cost in doing so.” So we’re not actually keeping a lot of balls in the air like an expert juggler; we’re more like a bad amateur plate spinner, frantically switching from one task to another, ignoring the one that is not right in front of us but worried it will come crashing down any minute. Even though we think we’re getting a lot done, ironically, multitasking makes us demonstrably less efficient. [Continue reading…]

Even the tech savvy should turn off their phones and listen

Bruno Giussani writes: Nothing exists nowadays unless it is Facebooked, Tweeted or Instagrammed with emphasis on “insta”. So perhaps the event that I hosted on Tuesday at the Royal Institution, TEDGlobal London, didn’t exist. Because we ran a little experiment, banning the use of smartphones, tablets, laptops, cameras – any electronic device – during the conference.

At the end of the event (which over two sessions of 100 minutes each featured scientists, technologists, historians, a photographer, a slam poet, a singer, a racing car driver and a writer) I asked the 350 attendees whether we should apply the same rule next time. It’s a safe guess that at least two-thirds of them use Twitter or FB with some regularity, but pretty much every hand in the theatre shot up, with maybe two exceptions. I have heard nothing but positive feedback since. [Continue reading…]

The collective power of human beings

American culture has made a fetish out of the rights and aspirations of the individual — hence at our head we have gathered an ineffectual assembly of dunces in the United States Capitol. But as Yuval Noah Harari points out, our human potential expresses itself much less in what we accomplish individually than in what we do together.

70,000 years ago humans were insignificant animals. The most important thing to know about prehistoric humans is that they were unimportant. Their impact on the world was very small, less than that of jellyfish, woodpeckers or bumblebees.

Today, however, humans control this planet. How did we reach from there to here? What was our secret of success, that turned us from insignificant apes minding their own business in a corner of Africa, into the rulers of the world?

We often look for the difference between us and other animals on the individual level. We want to believe that there is something special about the human body or human brain that makes each individual human vastly superior to a dog, or a pig, or a chimpanzee. But the fact is that one-on-one, humans are embarrassingly similar to chimpanzees. If you place me and a chimpanzee together on a lone island, to see who survives better, I would definitely place my bets on the chimp.

The real difference between us and other animals is on the collective level. [Continue reading…]
