For more than half a million years, our recent hominid ancestors lived nomadic lives of extreme duress on the plains of East Africa, but the advent of agriculture changed that about 10,000 years ago. That is only 400 generations—not enough to adapt, genetically, to the changes in diet and society that ensued. Privately worked land and the accumulation of capital made humans less oriented toward group welfare, and the Industrial Revolution pushed society further in that direction. No one knows how the so-called Information Age will affect us, but there’s a good chance that home technology and the Internet will only intensify our drift toward solipsism and alienation.

  Meanwhile, many of the behaviors that had high survival value in our evolutionary past, like problem-solving, cooperation, and intergroup competition, are still rewarded by bumps of dopamine and other hormones into our system. Those hormones serve to reinforce whatever behavior it was that produced those hormones in the first place. Group affiliation and cooperation were clearly adaptive because in many animals, including humans, they trigger a surge in levels of a neuropeptide called oxytocin. Not only does oxytocin create a glow of well-being in people, it promotes greater levels of trust and bonding, which unite them further still. Hominids that were rewarded with oxytocin for cooperating with one another must have out-fought, out-hunted, and out-bred the ones that didn’t. Those are the hominids that modern humans are descended from.

  According to one study published in Science in June 2010, this feedback loop of oxytocin and group loyalty creates an expectation that members will “self-sacrifice to contribute to in-group welfare.” There may be no better description of a soldier’s ethos than that sentence. One of the most noticeable things about life in the military is that you are virtually never alone: day after day, month after month, you are close enough to speak to, if not touch, a dozen or more people. You eat together, sleep together, laugh together, suffer together. That level of intimacy duplicates our evolutionary past very closely and must create a nearly continual oxytocin reward system.

  Hero’s Welcome

  When soldiers return to modern society, they must go through—among other adjustments—a terrific oxytocin withdrawal. The chronic isolation of modern society begins in childhood and continues our entire lives. Infants in hunter-gatherer societies are carried by their mothers as much as 50 to 90 percent of the time, often in wraps that keep them strapped to the mother’s back so that her hands are free. That roughly corresponds to carrying rates among other primates, according to primatologist and psychologist Harriet J. Smith. One can get an idea of how desperately important touch is to primates from a landmark experiment conducted in the 1950s by a psychologist and primatologist named Harry Harlow. Baby rhesus monkeys were separated from their mothers and presented with the choice of two kinds of surrogates: a cuddly mother made out of terry cloth or an uninviting mother made out of wire mesh. The wire-mesh mother, however, had a nipple that would dispense warm milk. The babies invariably took their nourishment quickly in order to rush back and cling to the terry-cloth mother, which had enough softness to provide the illusion of affection. But even that isn’t enough for psychological health: in a separate experiment, more than 75 percent of female baby rhesus monkeys raised with terry-cloth mothers—as opposed to real ones—grew up to be abusive and neglectful to their own young.

  In the 1970s, American mothers maintained skin-to-skin contact with their nine-month-old babies as little as 16 percent of the time, which is a level of contact that traditional societies would probably consider a form of child abuse. Also unthinkable would be the common practice of making young children sleep by themselves in their own room. 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 sixties 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 forty-eight 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.”

  Israel is arguably the only modern country that retains a sufficient sense of community to mitigate the effects of combat on a mass scale. Despite decades of intermittent war, the Israel Defense Forces have a PTSD rate as low as 1 percent. Two of the foremost reasons have to do with national military service and the proximity of the combat—the war is virtually on their doorstep. “Being in the military is something that most people have done,” I was told by Dr. Arieh Shalev, who has devoted the last twenty years to studying PTSD. “Those who come back from combat are reintegrated into a society where those experiences are very well understood. We did a study of seventeen-year-olds who had lost their father in the military, compared to those who had lost their fathers to accidents. The ones whose fathers died in combat did much better than those whose fathers hadn’t.”

  According to Shalev, the closer the public is to the actual combat, the better the war will be understood and the less difficulty soldiers will have when they come home. The Israelis are benefiting from what could be called the shared public meaning of a war. Such public meaning—which would often occur in more communal, tribal societies—seems to help soldiers even in a fully modern society such as Israel. It is probably not generated by empty, reflexive phrases—such as “Thank you for your service”—that many Americans feel compelled to offer soldiers and vets. If anything, those comments only serve to underline the enormous chasm between military and civilian society in this country.

  Another Israeli researcher, Reuven Gal, found that the perceived legitimacy of a war was more important to soldiers’ general morale than was the combat readiness of the unit they were in. And that legitimacy, in turn, was a function of the war’s physical distance from the homeland: “The Israeli soldiers who were abruptly mobilized and thrown into dreadful battles in the middle of Yom Kippur Day in 1973 had no doubts about the legitimacy of the war,” Gal wrote in the Journal of Applied Psychology in 1986. “Many of those soldiers who were fighting in the Golan Heights against the flood of Syrian tanks needed only to look behind their shoulders to see their homes and remind themselves that they were fighting for their very survival.”

  In that sense the Israelis are far more like the Sioux, Cheyenne, and Arapaho at Little Bighorn than they are like us. America’s distance from her enemies means that her wars have generally been fought far away from her population centers, and as a result those wars have been harder to explain and justify than Israel’s have been. The people who will bear the psychic cost of that ambiguity will, of course, be the soldiers.

  A Bright Shining Lie

  “I talked to my mom only one time from Mars,” a Vietnam vet named Gregory Gomez told me about the physical and spiritual distance between his home and the war zone. Gomez is a pure-blooded Apache who grew up in West Texas. He says his grandfather was arrested and executed by Texas Rangers in 1915 because they wanted his land; they strung him from a tree limb, cut off his genitals, and stuffed them in his mouth. Consequently, Gomez felt no allegiance to the U.S. government, but he volunteered for service in Vietnam anyway. “Most of us Indian guys who went to Vietnam went because we were warriors,” Gomez told me. “I did not fight for this country. I fought for Mother Earth. I wanted to experience combat. I wanted to know how I’d do.”

  Gomez was in a Marine Corps Force Recon unit, one of the most elite designations in the U.S. military. He was part of a four-man team that would insert by helicopter into enemy territory north of the DMZ and stay for two weeks at a time. They had no medic and no backup and didn’t even dare eat C rations, because, Gomez said, they were afraid their body odor would give them away. They ate Vietnamese food and watched enemy soldiers pass just yards away in the dense jungle. “Everyone who has lived through something like that has lived through trauma, and you can never go back,” he told me. “You are seventeen or eighteen or nineteen and you just hit that wall. You become very old men.”

  American Indians, proportionally, have provided more soldiers to America’s wars than almost any other ethnic group in this country. They are also the product of an ancient and vibrant warring culture that takes great pains to protect the warrior from society, and vice versa. Although those traditions have obviously broken down since the end of the Indian Wars, there may be something to be learned from the principles upon which they stand. When Gomez came home he essentially isolated himself for more than a decade. He didn’t drink, and he lived a normal life except that occasionally he’d go to the corner store to get a soda and would wind up in Oklahoma or East Texas without any idea how he got there.

  He finally started seeing a therapist at the VA as well as undergoing traditional Indian rituals. It was a combination that seemed to work. In the 1980s he underwent an extremely painful ceremony called the Sun Dance. At the start of the ceremony, the dancers have wooden skewers driven through the skin of their chests. Leather thongs are tied to the skewers and then attached to the top of a tall pole at the center of the dance ground. To a steady drumbeat, the dancers move in a circle while leaning back on the leather thongs until, after many hours, the skewers finally tear free. “I dance back and I throw my arms and yell and I can see the ropes and the piercing sticks like in slow motion, flying from my chest towards the grandfather’s tree,” Gomez told me about the experience. “And I had this incredible feeling of euphoria and strength, like I could do anything. That’s when the healing takes place. That’s when life changes take place.”

  America is a largely de-ritualized society that obviously can’t just borrow from another society to heal its psychic wounds. But the spirit of community healing and empowerment that forms the basis of these ceremonies is certainly one that might be converted to a secular modern society. The shocking disconnect for veterans isn’t so much that civilians don’t know what they went through—it’s unrealistic to expect anyone to fully understand another person’s experience—but that what they went through doesn’t seem relevant back home. Given the profound alienation that afflicts modern society, when combat vets say that they want to go back to war, they may be having an entirely healthy response to the perceived emptiness of modern life.

  One way to change this dynamic might be to emulate the Israelis and mandate national service (with a military or combat option). We could also emulate the Nepalese and try to have communities better integrate people of different ethnic and religious groups. Finally, we could emulate many tribal societies—including the Apache—by getting rid of parades and replacing them with some form of homecoming ceremony. An almost universal component of these ceremonies is the dramatic retelling of combat experiences to the warrior’s community. We could achieve that on Veterans Day by making every town and city hall in the country available to veterans who want to speak publicly about the war. The vapid phrase “I support the troops” would then mean actually showing up at your town hall every Veterans Day to hear these people out. Some vets will be angry, some will be proud, and some will be crying so hard they can’t speak. But a community ceremony like that would finally return the experience of war to our entire nation, rather than just leaving it to the people who fought.

  It might also
begin to reassemble a society that has been spiritually cannibalizing itself for generations. We keep wondering how to save the vets, but the real question is how to save ourselves. If we do that, the vets will be fine. If we don’t, it won’t matter anyway.

  Sexual Paranoia

  FROM The Chronicle Review

  You have to feel a little sorry these days for professors married to their former students. They used to be respectable citizens—leaders in their fields, department chairs, maybe even a dean or two—and now they’re abusers of power avant la lettre. I suspect you can barely throw a stone on most campuses around the country without hitting a few of these neo-miscreants. Who knows what coercions they deployed back in the day to corral those students into submission; at least that’s the fear evinced by today’s new campus dating policies. And think how their kids must feel! A friend of mine is the offspring of such a coupling—does she look at her father a little differently now, I wonder.

  It’s been barely a year since the Great Prohibition took effect in my own workplace. Before that, students and professors could date whomever we wanted; the next day we were off-limits to one another—verboten, traife, dangerous (and perhaps therefore all the more alluring).

  Of course, the residues of the wild old days are everywhere. On my campus, several such “mixed” couples leap to mind, including female professors wed to former students. Not to mention the legions who’ve dated a graduate student or two in their day—plenty of female professors in that category too; in fact, I’m one of them. Don’t ask for details. It’s one of those things it now behooves one to be reticent about, lest you be branded a predator.
