Fritz’s theory was that modern society has gravely disrupted the social bonds that have always characterized the human experience, and that disasters thrust people back into a more ancient, organic way of relating. Disasters, he proposed, create a “community of sufferers” that allows individuals to experience an immensely reassuring connection to others. As people come together to face an existential threat, Fritz found, class differences are temporarily erased, income disparities become irrelevant, race is overlooked, and individuals are assessed simply by what they are willing to do for the group. It is a kind of fleeting social utopia that, Fritz felt, is enormously gratifying to the average person and downright therapeutic to people suffering from mental illness.

There are more than 20,000 names in the Righteous Among the Nations records, and an analysis conducted in 2004 found that if married couples are excluded, women slightly outnumber men in the list of people who risked their lives to help Jews. The greater empathic concern women demonstrate for others may lead them to take positions on moral or social issues that men are less likely to concern themselves with. Women tend to act heroically within their own moral universe, regardless of whether anyone else knows about it—donating more kidneys to nonrelatives than men do, for example. Men, on the other hand, are far more likely to risk their lives at a moment’s notice, and that reaction is particularly strong when others are watching, or when they are part of a group.

The beauty and the tragedy of the modern world is that it eliminates many situations that require people to demonstrate a commitment to the collective good. Protected by police and fire departments and relieved of most of the challenges of survival, an urban man might go through his entire life without having to come to the aid of someone in danger—or even give up his dinner. Likewise, a woman in a society that has codified its moral behavior into a set of laws and penalties might never have to make a choice that puts her very life at risk. What would you risk dying for—and for whom—is perhaps the most profound question a person can ask themselves. The vast majority of people in modern society are able to pass their whole lives without ever having to answer that question, which is both an enormous blessing and a significant loss. It is a loss because having to face that question has, for tens of millennia, been one of the ways that we have defined ourselves as people. And it is a blessing because life has gotten far less difficult and traumatic than it was for most people even a century ago.

He was unable to find a single instance where communities that had been hit by catastrophic events lapsed into sustained panic, much less anything approaching anarchy. If anything, he found that social bonds were reinforced during disasters, and that people overwhelmingly devoted their energies toward the good of the community rather than just themselves.

American analysts based in England monitored the effects of the bombing to see if any cracks began to appear in the German resolve, and to their surprise found exactly the opposite: the more the Allies bombed, the more defiant the German population became. Industrial production actually rose in Germany during the war. And the cities with the highest morale were the ones—like Dresden—that were bombed the hardest. According to German psychologists who compared notes with their American counterparts after the war, it was the untouched cities where civilian morale suffered the most.

The positive effects of war on mental health were first noticed by the great sociologist Emile Durkheim, who found that when European countries went to war, suicide rates dropped. Psychiatric wards in Paris were strangely empty during both world wars, and that remained true even as the German army rolled into the city in 1940.

Boehm’s research has led him to believe that much of the evolutionary basis for moral behavior stems from group pressure. Not only are bad actions punished, but good actions are rewarded. When a person does something for another person—a prosocial act, as it’s called—they are rewarded not only by group approval but also by an increase of dopamine and other pleasurable hormones in their blood. Group cooperation triggers higher levels of oxytocin, for example, which promotes everything from breast-feeding in women to higher levels of trust and group bonding in men. Both reactions impart a powerful sensation of well-being. Oxytocin creates a feedback loop of good-feeling and group loyalty that ultimately leads members to “self-sacrifice to promote group welfare,” in the words of one study.

In his survey of ancestral-type societies, Boehm found that—in addition to murder and theft—one of the most commonly punished infractions was “failure to share.” Freeloading on the hard work of others and bullying were also high up on the list.

The findings are in keeping with something called self-determination theory, which holds that human beings need three basic things in order to be content: they need to feel competent at what they do; they need to feel authentic in their lives; and they need to feel connected to others. These values are considered “intrinsic” to human happiness and far outweigh “extrinsic” values such as beauty, money, and status.

A person living in a modern city or a suburb can, for the first time in history, go through an entire day—or an entire life—mostly encountering complete strangers. They can be surrounded by others and yet feel deeply, dangerously alone.

The evidence that this is hard on us is overwhelming. Although happiness is notoriously subjective and difficult to measure, mental illness is not. Numerous cross-cultural studies have shown that modern society—despite its nearly miraculous advances in medicine, science, and technology—is afflicted with some of the highest rates of depression, schizophrenia, poor health, anxiety, and chronic loneliness in human history. As affluence and urbanization rise in a society, rates of depression and suicide tend to go up rather than down. Rather than buffering people from clinical depression, increased wealth in a society seems to foster it.
