“Why does everything you know, and everything you’ve learned, confirm you in what you believed before? Whereas in my case, what I grew up with, and what I thought I believed, is chipped away a little and a little, a fragment then a piece and then a piece more. With every month that passes, the corners are knocked off the certainties of this world: and the next world too. Show me where it says, in the Bible, ‘Purgatory.’ Show me where it says ‘relics, monks, nuns.’ Show me where it says ‘Pope.’” –Thomas Cromwell imagines asking Thomas More—Wolf Hall by Hilary Mantel

In Suzanne Collins’ The Hunger Games, Katniss Everdeen reflects on how the life-or-death stakes of the contest she and her fellow “tributes” are made to participate in can transform teenage boys and girls into crazed killers. She’s been brought to a high-tech mega-city from District 12, a mining town as quaint as the so-called Capitol is futuristic. Peeta Mellark, who was chosen by lottery as the other half of the boy-girl pair of tributes from the district, has just said to her, “I want to die as myself…I don’t want them to change me in there. Turn me into some kind of monster that I’m not.” Peeta also wants “to show the Capitol they don’t own me. That I’m more than just a piece in their Games.” The idea startles Katniss, who at this point is thinking of nothing but surviving the games—knowing full well that there are twenty-two more tributes and only one will be allowed to leave the arena alive. Annoyed by Peeta’s pronouncement of a higher purpose, she thinks,
|John von Neumann|
John von Neumann, one of the founders of game theory, served an important role in developing the policies that have so far prevented the real life apocalypse from taking place. He is credited with the strategy of Mutually Assured Destruction, or MAD (he liked amusing acronyms), that prevailed during the Cold War. As the name implies, the goal was to assure the Soviets that if they attacked us everyone would die. Since the U.S. knew the same was true of any of our own plans to attack the Soviets, a tense peace, or Cold War, was the inevitable result. But von Neumann was not at all content with this peace. He devoted his twilight years to pushing for the development of Intercontinental Ballistic Missiles (ICBMs) that would allow the U.S. to bomb Russia without giving the Soviets a chance to respond. In 1950, he made the infamous remark that inspired Dr. Strangelove: “If you say why not bomb them tomorrow, I say, why not today. If you say today at five o’clock, I say why not one o’clock?”
Von Neumann’s eagerness to hit the Russians first was based on the logic of game theory, and that same logic is at play in The Hunger Games and other post-apocalyptic fiction. The problem with cooperation, whether between rival nations or between individual competitors in a game of life-or-death, is that it requires trust—and once one player begins to trust the other he or see becomes vulnerable to exploitation, the proverbial stab in the back from the person who’s supposed to be watching it. Game theorists model this dynamic with a thought experiment called the Prisoner’s Dilemma. Imagine two criminals are captured and taken to separate interrogation rooms. Each criminal has the option of either cooperating with the other criminal by remaining silent or betraying him or her by confessing. Here’s a graph of the possible outcomes:
But the way humans play games is a bit different. As it turned out, von Neumann was wrong about the game theory implications of the Cold War—neither side ever did pull the trigger; both prisoners kept their mouth shut. In Collins' novel, Katniss faces a Prisoner's Dilemma every time she encounters another tribute who may be willing to team up with her in the hunger game. The graph for her and Peeta looks like this:
Both improve chances of making it to final round.
Killing Peeta is easier.
Peeta’s strength and resourcefulness are wasted.
Killing Katniss is easier.
Katniss’ knowledge and skills are wasted.
Both avoid risks associated with betrayal.
Both miss out on benefits of other’s abilities.
We can’t help feeling strong positive emotions toward altruists. Katniss wins over readers and viewers the moment she volunteers to serve as tribute in place of her younger sister, whose name was picked in the lottery. What’s interesting, though, is that at several points in the story Katniss actually does engage in purely rational strategizing. She doesn’t attempt to help Peeta for a long time after she finds out he’s been wounded trying to protect her—why would she when they’re only going to have to fight each other in later rounds? But when it really comes down to it, when it really matters most, both Katniss and Peeta demonstrate that they’re willing to protect one another even at a cost to themselves.
The birth of humanity occurred, somewhat figuratively, when people refused to play the game of me versus you and determined instead to play us versus them. Humans don’t like zero-sum games, and whenever possible they try to change to the rules so there can be more than one winner. To do that, though, they have to make it clear that they would rather die than betray their teammates. In The Road, the father and his son continue to carry the fire, and in The Hunger Games Peeta gets his chance to show he’d rather die than be turned into a monster. By the end of the story, it’s really no surprise what Katniss choses to do either. Saving her sister may not have been purely altruistic from a genetic standpoint. But Peeta isn’t related to her, nor is he her only—or even her most eligible—suitor. Still, her moments of cold strategizing notwithstanding, we've had her picked as an altruist all along.
Of course, humanity may have begun with the sense that it’s us versus them, but as it’s matured the us has grown to encompass an ever wider assortment of people and the them has receded to include more and more circumscribed groups of evil-doers. Unfortunately, there are still all too many people who are overly eager to treat unfamiliar groups as rival tribes, and all too many people who believe that the best governing principle for society is competition—the war of all against all. Altruism is one of the main hallmarks of humanity, and yet some people are simply more altruistic than others. Let’s just hope that it doesn’t come down to us versus them…again.

Brief stage shows like the one featuring the nice and naughty puppets are part of an ongoing research program lead by Karen Wynn, Bloom’s wife and colleague, and graduate student Kiley Hamlin at Yale University’s Infant Cognition Center. An earlier permutation of the study was featured on PBS’s Nova series The Human Spark (jump to chapter 5), which shows host Alan Alda looking on as an infant named Jessica attends to a puppet show with the same script as the one that riled the boy Bloom describes. Jessica is so tiny that her ability to track and interpret the puppets’ behavior on any level is impressive, but when she demonstrates a rudimentary capacity for moral judgment by reaching with unchecked joy for the nice puppet while barely glancing at the mean one, Alda—and Nova viewers along with him—can’t help but demonstrate his own delight. Jessica shows unmistakable signs of positive emotion in response to the nice puppet’s behaviors, and Alda in turn feels positive emotions toward Jessica. Bloom attests that “if you watch the older babies during the experiments, they don’t act like impassive judges—they tend to smile and clap during good events and frown, shake their heads and look sad during the naughty events” (6). Any adult witnessing the children’s reactions can be counted on to mirror these expressions and to feel delight at the babies’ incredible precocity.
If, however, individuals given to trying to take advantage of cooperative norms were reliably met with slaps on the head—or with ostracism in the wake of spreading gossip—any benefits they (or their genes) might otherwise count on to redound from their selfish behavior would be much diminished. Flesch’s theory is “that we have explicitly evolved the ability and desire to track others and to learn their stories precisely in order to punish the guilty (and somewhat secondarily to reward the virtuous)” (21). Before strong reciprocity was driving humans to bookstores, amphitheaters, and cinemas, then, it was serving the life-and-death cause of ensuring group cohesion and sealing group boundaries against neighboring exploiters.
Note that the third player gets nothing out of paying to reward or punish except the power or agency to do just that. It is highly irrational for this player to pay to reward or punish, but again considerations of fairness trump rational self-interest. People do pay, and pay a substantial amount, when they think that someone has been treated notably unfairly, or when they think someone has evinced marked generosity, to affect what they have observed. (33)

If there is a lot of between-group competition, then those groups whose modes of costly signaling take the form of strong reciprocity, especially altruistic punishment, will outcompete those whose modes yield less secondary gain, especially less secondary gain for the group as a whole. (57)
When the target of the action was itself a good guy, babies preferred the puppet who was nice to it. This alone wasn’t very surprising, given that the other studies found an overall preference among babies for those who act nicely. What was more interesting was what happened when they watched the bad guy being rewarded or punished. Here they chose the punisher. Despite their overall preference for good actors over bad, then, babies are drawn to bad actors when those actors are punishing bad behavior. (5)
