So far, Pinker has argued that the history of human beings has been shaped by violence. He has also noted that violence has declined. There is nothing about human nature that is exclusively violent or peaceful. The environment that we occupy, either through our own innovations or by sheer accident, is what determines our movement in either direction.
He then cites works of art that explore the violent nature of human beings.
Bad Men Do What Good Men Dream, Bible stories, Homeric sagas, martyrologies, portrayals of hell, hero myths, Gilgamesh, Greek tragedies, Beowulf, the Bayeux Tapestry, Shakespearean dramas, Grimm’s fairy tales, Punch and Judy, opera, murder mysteries, penny dreadfuls, pulp fiction, dime novels, Grand Guignol, murder ballads, films noirs, Westerns, horror comics, superhero comics, the Three Stooges, Tom and Jerry, the Road Runner, video games, and movies starring a certain ex-governor of California.The Better Angels of Our Nature, Steven Pinker
Even in wartime, many soldiers do not fire their weapons and are racked by posttraumatic stress disorder when they do. Some writers have concluded that most humans are constitutionally averse to violence. But the default human conditioning is towards violence. Even toddlers are violent. The question should not be why they are aggressive, but how they learn to not be aggressive?
We are attracted to extremes – illicit sex, violence, and giant leaps of status.
But if violence is hardwired into us, then why do soldiers feel reluctant to fire their guns in combat? A study found that less than 25 percent of veterans ever fired a gun in World War II.
It is not because human beings are gentle and compassionate that they exercise of constraint. Pinker cites Darwin and Hobbes when he analyzes the nature of violence. From these authors we can learn that human beings, unlike rocks, take part in a world everyone else takes part in. The individual that evolves violent tendencies is surrounded by other individuals who have evolved the same tendencies. If you harm others, they will probably harm you back. And others are motivated to harm you even before you harm them.
The Moralization Gap and The Myth of Pure Evil
There is a modern denial of the dark side of human nature.
Each person has either taken a perpetrator or victim viewpoint. The perpetrator excuses his behavior with self-serving facts “It’s not fair to blame me”. The victim frames the behavior of the perpetrator as a continuation of a series of mistakes, “You always do this”.
But self-serving biases are part of the evolutionary price we pay for being social animals. People congregate in groups for good reason. They look for warmth, cooperation, reciprocal exchange.
Trivers was the first to suggest that moral emotions were adaptations to cooperation. But there is more. When you convey an exaggerated impression of kindness and skill, others are bound to develop the ability to see through it – setting an evolutionary arms race between better liars and better lie detection. Lies can be spotted though internal contradictions, “A liar must have a good memory”, or through physical tells such as blushes and hesitations.
Trivers ventured that natural selection may have favored a degree ofself-deceptionso as to suppress the tells at the source. We lie to ourselves so that we’re more believable when we lie to others. At the same time, an unconscious part of the mind registers the truth about our abilities so that we don’t get too far out of touch with reality. Trivers credits George Orwell with an earlier formulation of the idea: “The secret of rulership is to combine a belief in one’s own infallibility with a power to learn from past mistakes.”The Better Angels of Our Nature, Steven Pinker
But Self-deception makes the paradoxical claim that something called “the self” can both deceive and be deceived at the same time. It is easy to show that people are liable to self-serving biases, but it is difficult to show that people are liable to self-deception.
Two social psychologists ran a brilliant experiment where half the participants would get a pleasant tasks like looking through photographs for ten minutes, and half would get a difficult task like solving math problems for forty five minutes. The participants were told that they would be run in pairs, but it was not yet decided who got which task.
So they allowed each participant to choose one of two methods to decide who would get the pleasant task, and who would get the unpleasant one. The participants could either choose the easy task for themselves or they could use a random number generator that determined who would get the different tasks.
Since humans are selfish, almost everyone kept the pleasant task for themselves. In a questionnaire they were later given, almost everyone thought that they were being fair, but did not think that the way others behaved was fair at all. The difference between how they judged others and how they judged their own behavior is a classic example of self-serving bias.
But did the self-servers really believe that they were acting fairly? Or was did their unconscious brain register the truth, while the conscious spin doctor in their brains selected the most convenient narrative? The psychologists wanted to find out, so they tied up the conscious brains of the participants by asking them to hold seven digits in memory while they evaluated the experiment. Since their conscious minds were distracted, the terrible truth came out. The participants were as harsh on themselves as they were on other people. Trivers was right – the truth was in there all along.
This is an encouraging result, because it suggests that while we do tend to deceive ourselves, we also can acknowledge the truth. Freud suggested that we use denial, repression, reaction formation, and projection to postpone facing the truth, but at least in principle, it is possible.
Once you become aware of this fateful quirk in our psychology, social life begins to look different, and so do history and current events. It’s not just that there are two sides to every dispute. It’s that each side sincerely believes its version of the story, namely that it is an innocent and longsuffering victim and the other side a malevolent and treacherous sadist. And each side has assembled a historical narrative and database of facts consistent with its sincere belief.The Better Angels of Our Nature, Steven Pinker
Violence may be motivated by a need for dominance or practical considerations. The need for dominance can be tied to testosterone drives or Intermale Aggression system.
The practical, instrumental kind of violence where goals such as lust, power, or ambition is pursued is set up by the Seeking system in the brain and is guided by the person’s intelligence.
There are three other reasons for violence – and they include revenge, sadism, an ideology.
1 to 3 percent of males are psychopaths. And psychopaths are liars and bullies since childhood. Sometimes, psychopathy comes from brain damage, other times, it is heritable. Psychopathy evolved as a minority strategy that exploits a large population of trusting cooperators.
Many studies have shown that people are overly optimistic about their competence, health, intelligence, and athleticism. People also think they are inherently lucky, and most people think they are more likely than others to live a long life and to have gifted children. They also think they are less likely going to be a victim of accident, crime, disease, or unwanted pregnancy.
Why should people be so deluded? Positive illusions make people happier, more confident, and mentally healthier. But this does not explain why it is better to have positive illusions than to have a better sense of reality. A plausible explanation is that some degree of incredulity is evolutionarily useful. If you want to recruit an ally to support you in a risky venture, or bargaining for a better deal, or intimidating an adversary into backing down, you need to exaggerate your strengths if you are going to be given any credibility.
And it is better to believe your own bullshit than to cynically lie about it. Since lie detection co-evolved with the ability to lie, it is not a good tactic to constantly rely on deception. If your exaggerations are not ludicrous, then your audience will have to lend you some degree of credibility. It would be better for the species if everyone was completely honest, but this strategy is disastrous for the individual. You cannot afford to be the only honest person in a society of liars.
But overconfidence can make people engage in battles they cannot win. This is when it becomes dangerous. Many fights and wars happened for this reason.
Dominance
Dominance hierarchies are based on more than brute strength. The ability to recruit allies, who choose to team up with the strongest and the smartest. The difference between predation and dominance is that the former is only about attaining the object of desire while the latter is about playing mind games (flaunting, flexing).
Dominance is also based on data. To avoid a fight, competitors must know who is stronger. Common knowledge may be undermined by contrary opinion, so dominance contests are also fought in the arenas of public information.
When dominance is reckoned within a closed group, it is a zero-sum game: if someone’s rank goes up, another’s has to go down. Dominance tends to erupt in violence within small groups like gangs and isolated workplaces, where a person’s rank within the clique determines the entirety of his social worth. If people belong to many groups and can switch in and out of them, they are more likely to find one in which they are esteemed, and an insult or slight is less consequential.The Better Angels of Our Nature, Steven Pinker
Testosterone usually makes animals more aggressive. But it is more complicated in humans. Men, for example, do not get more aggressive because of testosterone. But testosterone makes men more prepared for dominance contests.
In men, testosterone levels rise in the presence of an attractive female and in anticipation of competition with other men, such as in sports. Once a match has begun, testosterone rises even more, and when the match has been decided, testosterone continues to rise in the winner but not in the loser. Men who have higher levels of testosterone play more aggressively, have angrier faces during competition, smile less often, and have firmer handshakes.
Men with higher levels of testosterone also shake hands more firmly and perceive neutral faces as angry. Testosterone levels decline when men get married, have children, and spend time with their children. The hormone is an internal regulator of the basic tradeoff between parenting effort and mating effort where the latter consists of fending off rivals and wooing the opposite sex.
Over the past century, dominance as a concept has been deconstructed.
Sadism
The development of sadism requires two things: motives to enjoy the suffering of others, and a removal of the restraints that ordinarily inhibit people from acting on them.The Better Angels of Our Nature, Steven Pinker
Human nature comes with four motives to find satisfaction in the pain of others. One is a fascination with the vulnerability of living things. This is what causes boys to fry ants wi
