The Better Angels of Our Nature by Steven Pinker

The Better Angels of our Nature: the decline of violence in history and its causes / Steven Pinker.  (Allen Lane, 2011 (ISBN: 978-1-846-14093-8))
A really useful look at the causes of violence, the levels at different times in history and the position now. SP identifies the following major aspects as Six Trends, Five Inner Demons, Four Better Angels and Five Historical Forces. [Note: This is a long post as there was so much I wanted to note down and look at again.]
Six Trends:
1.       Transition from the anarchy of the hunting, gathering and horticultural societies to the first agricultural civilizations with cities and governments, beginning around five thousand years ago. With that change came a reduction in the chronic raiding and feuding and a more or less fivefold decrease in rates of violent death. [Pacification Process]
2.       Spanning more than half a millennium (late Middle Ages to the 20th century), and best documented in Europe, this transition saw a tenfold-to-fiftyfold decline in the rates of homicide. Attributed to consolidation of feudal territories into large kingdoms with centralized authority and infrastructure of commerce. [Civilizing Process]
3.       Unfolded over centuries, taking off around the Age of Reason and the European Enlightenment (17th and 18th centuries) – though with antecedents in classical Greece and the Renaissance. Saw the first organized movements to abolish socially sanctioned forms of violence like despotism, slavery, duelling, judicial torture, superstitious killing, sadistic punishment and cruelty to animals, together with the first stirrings of systematic pacifism. [Humanitarian Revolution]
4.       Following the end of WW2 there has been an unprecedented development of the great powers and developed states in general stopping waging war on one another. [Long Peace]
5.       Since the end of the Cold War in 1989, organized conflicts of all kinds (civil wars, genocides, repression by autocratic governments and terrorist attacks) have declined throughout the world. [New Peace]
6.       The post war era (and the Universal Declaration of Human Rights) has seen a growing revulsion against aggression on smaller scales, including violence against ethnic minorities, women, children, homosexuals and animals. [Rights Revolutions]
Five Inner Demons
Contemporary scientific understanding of the psychology of violence is that it is the output of several psychological systems that differ in their environmental triggers, their internal logic, their neurological basis and their social distribution.
1.       Predatorary or instrumental violence is violence deployed as a practical means to an end.
2.       Dominance is the urge for authority, prestige, glory and power, whether it takes the form of macho posturing among individuals or contests for supremacy among racial, ethnic, religious or national groups.
3.       Revenge fuels the moralistic urge toward retribution, punishment and justice.
4.       Sadism is the pleasure taken in another’s suffering.
5.       Ideology is a shared belief system, usually involving a vision of utopia, which justifies unlimited violence in pursuit of unlimited good.
Four Better Angels
Humans are not innately good or evil but come with motives that can orient them away from violence and toward cooperation and altruism.
1.       Empathy (particularly the sense of sympathetic concern) prompts us to feel the pain of others and to align their interests with our own.
2.       Self-control allows us to anticipate the consequences of acting on our impulses and to inhibit them accordingly.
3.       Moral sense sanctifies a set of norms and taboos that govern the interaction among people in a culture, sometimes in ways that decrease violence, though often (when the norms are tribal, authoritarian or puritanical) in ways that increase it.
4.       Reason allows us to extricate ourselves from our parochial vantage points, to reflect on the ways in which we live our lives, to deduce ways in which we could be better off, and to guide the application of the other better angels of our nature. SP also examines the possibility that in recent history Homo sapiens has literally evolved to become less violent in the biologist’s technical sense of a change in our genome.
Five Historical Forces
Exogenous forces that favour our peaceable motives and that have driven the multiples declines in violence are identified.
1.       Leviathan: a state and judiciary with a monopoly on the legitimate use of force can defuse the temptation of exploitative attack, inhibit the impulse for revenge, and circumvent the self-serving biases that make all parties believe they are on the side of the angels.
2.       Commerce: a positive-sum game in which everybody can win; as technological progress allows the exchange of goods and ideas over longer distances and among larger groups of trading partners, other people become more valuable alive than dead, and they are less likely to become targets of demonization and dehumanization.
3.       Feminization: the process in which cultures have increasingly respected the interests and values of women. Since violence is largely a male pastime, cultures that empower women tend to move away from the glorification of violence and are less likely to breed dangerous subcultures of rootless young men.
4.       Cosmopolitanism: forces such as literacy, mobility and mass media can prompt people to take the perspective of people unlike themselves and to expand their circle of sympathy to embrace them.
5.       Escalator of reason: an intensifying application of knowledge and rationality to human affairs can force people to recognize the futility of cycles of violence, to ramp down the privileging of their own interests over others, and to reframe violence as a problem to be solved rather than a contest to be won.
Pacification Process
All species want to pass on their genes; this leads to predators and parasites. Victims can also be members of the same species – infanticide, sibicide, cannibalism, rape and lethal combat have been documented in many kinds of animals. But animals are also less inclined to harm close relatives, who share genetic material. When a tendency to violence emerges, it is always strategic; violence is deployed when expected benefits outweigh expected costs.
Competition is built into the evolutionary process. (1) ‘Wives’ are competed over, as in most species the female makes a greater investment than the male, especially in mammals. (2) Competition breeds fear – leading to strike first. Deterrence works if (a) don’t strike first, (b) be strong enough to survive first hit and (3) retaliate in kind.
Leviathan – monarchy or other government authority that embodies the will of the people and has a monopoly on the use of force.
Chimpanzee aggression is territorial – a group encountering another group at a boundary leads to a noisy ‘battle’ but not serious fighting. But male groups encountering a smaller group or individual take advantage of numbers – to mate with female, to attack female and kill baby, or to kill male. Killings may occur within a group as well. Humans share a common ancestor with chimps.
Forensic archaeology shows cannibalism widespread in human prehistory. Humans fight for gain, safety and credible deterrence.

Reduction of homicide rates by government control is so obvious to anthropologists that it is seldom documented by numbers. (The various ‘paxes’ – Pax Romanica, Islamica, Mongolica, Hispnaica, etc. – refer to the reduction in raiding, feuding and warfare in territories brought under the control of an effective government.) A tragic irony of the second half of the twentieth century is that when colonies in the developing world freed themselves from European rule, they often slid back into warfare, this time intensified by modern weaponry, organized militias and the freedom of young men to defy tribal leaders.
States emerged first as stratified theocracies in which elites secured their economic privileges by enforcing a brutal peace on their underlings.
Civilizing Process
Homicide in England went from 4 to 100 per 100,000 in the Middle Ages to 0.8 persons per 100,000 in the 1950s. By the 20th century, in every Western European country the homicide rate was in a narrow band centred on 1 per 100,000.
Certain patterns remained constant. Men are responsible for around 92% of all killings (except infanticide) and are most likely to kill in their twenties.
Other patterns changed. In earlier centuries homicide rates in all social classes were similar, but as rates fell, they dropped far more among the upper classes than the lower. Also the rate of men killing unrelated men declined more rapidly than men killing their own children, parents, spouses and siblings.
The knights of feudal Europe were warlords. States were ineffectual. Kings were merely the most prominent lords, with no permanent army and little control over the country. Private wars and tournaments were common. Religious values were imparted with threats of eternal torture and depictions of mutilated saints. Brigands threatened travel and ransoming captives was big business.
Evidence for change comes from medieval manuals of etiquette which focus on (1) control your appetites, (2) delay gratification, (3) consider the sensibilities of others, (4) don’t act like a peasant and (5) distance yourself from your animal nature. Knives routinely used at meal tables, then usage at meals defined, then forks in use and table knives had rounded ends. Standards trickled down from the upper classes to the bourgeoisie and then to the lower classes.
Twofold outside trigger for change: A. Centralized monarchies gained in strength and legal systems redefined homicide from a tort (victim’s family could demand ‘blood money’ from killer’s family) to an offense against the state (crown). B. Money increasingly replaced barter. Roads were built, allowing easier transport of goods. New technologies needed expert craftsmen. A & B reinforce each other. [The decrease in violence did not always proceed in step with the rise of centralised states but many criminologists believe the source of the pacifying effect of states is due to the trust they command among the populace.]
Today, statistics from every Western country show the overwhelming majority of homicides and other violent crimes are committed by people from the lowest socio-economic groups. While elites and middle class pursue justice through the legal system, the lower classes resort to self-help (vigilantism, frontier justice, taking the law into your own hands). Most homicides are really instances of capital punishment, with a private citizen as judge, jury and executioner. Lower status people and the legal system often live in a condition of mutual hostility.
The civilizing process also spread outwards from a Western European epicentre. England was the first to pacify itself, followed by Germany and the Low Countries. The late 1800s saw a peaceful centre (Britain, France, Germany, Denmark and the Low Countries) bordered by slightly stroppier Ireland, Austro-Hungary and Finland, surrounded in turn by still more violent Spain, Italy, Greece and the Slavic countries. Today a gradient of lawlessness extending to Eastern Europe and the mountainous Balkans is still visible.
There are also gradients within countries – the hinterlands and mountains remained violent long after the urbanized and densely farmed centres calmed down. Most European countries have kept dependable homicide statistics for a century or more. On other continents quoted homicide rates are often unreliable and sometimes incredible; it can be hard to draw a line between casualties in a civil war and homicides from organized crime. Despite these limitations, the median national homicide rate is now 6 per 100,000.
The least violent region is Western and Central Europe and what were parts of the British Empire (Australia, New Zealand, Fiji, Canada, the Maldives and Bermuda). Other low rate countries adopted European standards – Japan, Singapore and Hong Kong. China also reports a low rate of 2.2 per 100,000.
The relationship between crime and democratization is in inverted U. Established democracies and autocracies are relatively safe places, but emerging democracies and semi-democracies are often plagued by crime and vulnerable to civil war. The most crime-prone regions today are Russia, Sub-Saharan Africa and parts of Latin America. The decivilizing process has also racked many countries that switched from tribal ways to colonial rule, then went suddenly to independence.
The USA, instead of clustering with kindred peoples like Britain, the Netherlands and Germany, has a homicide rate close to the median rate for the whole world, along with Albania and Uruguay, and has shown no overall decline in the 20th century. However, homicide rates vary widely across the USA. A band of northern states (including new England) have rates (less than 3 per 100,000) comparable with Europe. Below this is a north-south gradient of increasing rates (Louisiana has 14.2 per 100,000). Higher rates are seen in areas with high proportions of African Americans, who tend to be in lower income levels. The American South still has an obsession with self-help justice and a culture of ‘honour’. One explanation is that the interior south was settled by Scots-Irish, mostly sheepherders. Herders all over the world cultivate a hair-trigger for retaliation. Cultural mores can persist long after the circumstances that gave rise to them have gone. The decline of violence in the west frontier areas lagged two centuries behind the east.
Cads and dads: An ecosystem with equal numbers of men and women will favour dads and one populated mainly by men or where women are plentiful but some men can monopolise them, will favour cads.
In the 1960s, European countries and America saw an upturn in violence for three decades. This is typically explained as a combination of changes in cultural norms, informalization (in manners, dress and language), a levelling of hierarchies, an elevation of adolescence over adulthood, the sexual revolution and experimentation with drugs. [NB: Recent research indicates the prime factor was lead in petrol. The dates of removal of lead plus twenty years match the 1990s decline almost exactly. This was not known to Pinker. Blog author.]
The Humanitarian Revolution
In the modern West and much of the rest of the world, capital and corporal punishments have been effectively eliminated, government’s power to use violence against their subjects severely curtailed, slavery abolished and people have lost their thirst for cruelty. This change began with the Age of Reason (17th c.) and crested with the Enlightenment at the end of the 1800s.
History shows a longer decline. Human sacrifice was common, but replaced by a belief in witchcraft and violence against those thought to be witches, then violence against blasphemers, heretics and apostates. People become wedded to their beliefs – challenge them and you challenge a person’s dignity, standing and power.
1095-1208 Crusaders killed an estimated 1 million. In the 13th century, the Albigensian Crusade killed around 200,000. From the late 15th to early 18th centuries, the Spanish Inquisition killed an estimated 350,000.
People started to put a higher value on human life, in part due to a new habit of identifying with the pains and pleasures of other people. This was helped by growing writing and literacy. By reading, you are observing the world from someone else’s viewpoint.
At the same time that capital punishment declined, so did the number of crimes for which it was used. The method of execution changed too, becoming less violent. European countries, none of which execute people, have the lowest homicide rates in the world.
Christianity started as a pacifist movement, but things went downhill when Constantine saw a vision of a flaming cross and the words ‘In this sign I will conquer’.
Kant identified three conditions for perpetual peace. (1) States should be democratic – the benefits of war go to the leaders and the costs are borne by its citizens. (2) The law of nations shall be founded on a League of Nations. (3) Universal law of hospitality or world citizenship. People from one country should be free to live in safety in others, as long as they do not bring an army with them.
Unspoken norms of civilised behaviour, both in everyday interactions and in the conduct of government, may be a prerequisite to implementing certain reforms successfully. They may explain why it is hard to impose liberal democracy on countries in the developing world that have not outgrown their superstitions, warlords and feuding tribes. People are embedded in a culture and find meaning in its myths, symbols and epics.
The Long Peace
While the first half of the 20th century saw a cascade of world wars, civil wars and genocides, the second half saw a historically unprecedented avoidance of war between the great powers. The components of long-term trends in wars between states are (1) there are no cycles, (2) a lot of randomness, (3) an escalation, recently reversed, in the destructiveness of war and (4) declines in every other dimension of war and thus in interstate war as a whole.
It is impossible to determine the bloodiest century in history. While the 20th century had more violent deaths than earlier ones, it also had more people. The death count of wars in 1800 must be multiplied by 2.5, in 1600 by 4.5, in 1300 by 7 and in 1CE by 15. People think the rate is higher as it is recent history. Statistical analysis shows the most serious wars and atrocities are pretty well evenly distributed over the last 2,500 years and that the size of conflicts taper down towards the present.
A common language does not make two factions less likely to go to war but a long-standing government inhibits fighting: peoples on one side of a national border are less likely to have a civil war than people on opposite sides are to have an interstate war. Countries are more likely to fight their neighbours but great powers (empires) are more likely to fight everyone. Certain cultures, especially with a military ideology, are more prone to go to war. There is no such thing as a ‘typical war’. Wars begin and end randomly. Short wars are more common than longer ones. Combatants fight longer when a war is more lethal.
From 1820 to 2000 the most damaging kinds of lethal violence were murders and world wars. In the world as a whole, homicides outnumber war-related deaths (even if this includes indirect deaths from hunger and disease. Luard identified five ages of war: (1) age of dynasties (1400-1559), (2) age of religions (1559-1648), (3) age of sovereignty (states) (1648-1789), (4) age of nationalism (1789-1917) and (5) age of ideology (1917 on). There is no such thing as a ‘nation’ in the sense of an ethnocultural group that coincides with a patch of real estate.
Since 1945 there have been zero instances of: nuclear weapons used in conflict; the two Cold War superpowers fighting each other on the battlefield; any of the great powers fighting each other since 1953; interstate wars fought in Western Europe since 1945 and Europe as a whole since 1956; interstate wars between major developed countries (the 44 with the highest per capita income; developed countries expanding their territory by conquest; and internationally recognized states going out of existence by conquest.
After 1945, there has been a world-wide steady reduction in the length of compulsory military service and now in the elimination of conscription altogether. The United Nations ‘froze’ national borders; existing states and borders were sacrosanct (even if they made little sense). Since 1951 there have only been ten invasions that resulted in major change in national boundaries, all before 1975. The use of poison gas in WW1 was followed by a worldwide revulsion leading to its outlawing in the Geneva Protocol. The late 1950s and early 1060s also saw demonstrations in democracies against nuclear weapons and war itself. Democracy, trade and membership of intergovernmental organisations all favour peace.
The New Peace
Three kinds of organized violence have increased pessimism: (1) civil wars that plague the developing world, (2) mass killing of ethnic and political groups and (3) terrorism. Political scientists have tried to measure these and surprisingly found that all three kinds are in decline.
The historical record has a Eurocentric bias but other continents suffered predation, feuding and slave raiding, followed by colonial conquest but there is little record of numbers or events until 1946. The datasets now being built up count only direct deaths; a problem with estimating indirect deaths is that there are too many other external factors – e.g. a drought year or viral epidemic.
Wars today take place mainly in poor countries, mostly in an arc that extends from Central & East Africa through the Middle East, across Southwest Asia and northern India, and down into Southeast Asia. About half the conflicts take place in the countries with the poorest sixth of the people. Neither the economic or geographic linkage with war is constant in history: for half a millennium the wealthy countries of Europe were constantly fighting. Many governments of newly independent colonies were run by strongmen, kleptocrats and the occasional psychotic, leaving large parts of their country in anarchy. Ideologies, whether political or religious, are deadly because they inflame leaders into trying to outlast their adversaries in destructive wars of attrition, regardless of the human cost. Anocracies are neither fully democratic nor fully autocratic – so do not do anything well. Countries with an abundance of natural resources have slower economic growth, crappier governments and more violence, while foreign aid often ends up enriching the leaders rather than building a sustainable infrastructure. International peacekeepers help in stopping violence and on average prevent hostilities restarting.
Genocide has been practised in all regions of the world and in all periods in history. It is the hardest to comprehend and shocks by the number of its victims. To make sense of this, we need to begin with the psychology of categories. People sort others into mental pigeonholes using customs, appearances and beliefs. To generalize from a category can be helpful – all raspberries are edible. But when people are categorized, we act as if a stereotype applies to every man, woman and child. We also assign good traits to our allies and negative ones to enemies. As people get older, they also tend to think that members of particular ethnic and religious groups share a biological heritage which makes them homogenous, unchangeable, predictable and distinct from other groups. Attacks typically lead to retaliation. However, politicides and/or ethnocides may be termed genocides. Rates for such attacks have declined since the 1970s. Predictors of genocide are (1) previous history of genocide, (2) immediate history of political instability, (3) a ruling elite coming from an ethnic minority, (4) democracy, (5) openness to trade and (6) an exclusionary ideology (e.g. Marxism, Islamism (especially a strict application of Sharia law), militaristic anticommunism, and forms of nationalism that demonize ethnic or religious rivals.
Terrorism is an unusual form of violence in its ratio of fear to harm – panic is the whole point. Motivated by a cause they act by surprise and in secrecy; they seek publicity and attention, which they get through fear. In most of the developed world, terrorism has failed; most terrorist groups fail and die out; those that primarily target civilians always failed. Suicide terrorism accounts for a minority of attacks, but a majority of casualties. Such terrorists tend to be educated, middle-class, morally engaged and free of obvious psychopathy; the most effective recruitment is to join a band of brothers, with commitment to a group intensified by religion.
There are signs that Islamist terrorism is beginning to burn out. The attacks erase all sympathy for the group, and Muslims are increasingly repulsed by the savagery. However, terrorism is a tactic, not an ideology or a regime, so there will always be a risk. Although about a fifth of the world’s population is Muslim, and about a quarter of the world’s countries have a Muslim majority, more than half the armed conflicts in 2008 embroiled Muslim countries or insurgencies. Muslim countries force a greater proportion of their citizens into armies than non-Muslim countries do. Only about a quarter of Islamic countries elect their governments and most of them are only dubiously democratic, with fewer political rights. They were the last to abolish slavery, still traffic people, and witchcraft is a crime. Violence is sanctioned by religious superstition and a hyper-developed culture of ‘honour’. The historical lack of separation between mosque and state has meant lost opportunities for absorbing and combining new ideas. Islamic conflicts have continued at the same historic rate while the rest of the world got more peaceful.
The Rights Revolutions
The post-war revulsion against forms of violence that kill in millions and thousands (war and genocide) has spread to forms that kill by hundreds, tens and single digits (e.g. rioting, lynching and hate crimes), extended to other forms of harm such as rape, assault, battering and intimidation and spread to vulnerable classes of victims that in earlier eras fell outside the circle of protection (racial minorities, women, children, homosexuals and animals).
Hate crimes: Following the 9/11 attacks and the London and Madrid bombings, there were no anti-Muslim fatalities in the West. Official discrimination by governments is in decline. In the USA white American’s attitude to African Americans has changed. By the 1980s few would oppose black children attending white schools or move away if a black family moved in next door or believe they are lazier and less intelligent; almost 80% were ok with racial intermarriage.
While rape is a human universal, so are proscriptions against rape; however, acknowledgement of the harm of rape from the viewpoint of the victim has taken time. Women were historically seen as property (chattels) and rape was seen as an offense against a man – the woman’s father, her husband, or in the case of a slave, her owner. Moral and legal systems all over the world codified rape in similar ways. Well into the 1970s, marital rape was not a crime in any state and the legal system underweighted the interests of women in other rapes. While not a part of normal male sexuality, it is made possible by the fact that male desire can be indiscriminate in its choice of partner. Men underestimate how upsetting sexual aggression is to a female victim.
The treatment of rape in popular culture has changed. A content analysis of video games dating back to the 1980s revealed a taboo on rape, with just a handful of exceptions. The facts of rape are elusive, as it is notoriously underreported by victims and at the same time over-reported publicly as news in what are later found to be false allegations. The American rape rate began to fall around 1979, dropped more steeply in the 1990s and has continued downwards.
The rate of domestic abuse has also fallen. It may be related to the biological phenomenon of mate-guarding. Practices such as veiling, chaperoning, chastity belts, claustration, segregation by sex, and female genital cutting appear to be culturally-sanctioned mate-guarding tactics.
Since definitions of rape and spousal abuse, how data is recorded and the willingness of victims to report rapes vary around the world, it is difficult to get good data but it does seem that similar declines have taken place in other Western democracies but are far worse off in countries outside Western Europe and the Anglosphere, where laws on violence against women lag behind. Pinker believes that this violence will decrease over time, with pressure from the top (the international community) and from below (individual attitudes).
Infanticide has been practiced on every continent and in every kind of society. It has been theorized that a women would let a newborn die if its prospects for survival to adulthood were poor (through deformity, famine, not sired by husband, older sibling not weaned) and some research appears to bear this out to a degree. Female infanticide is found in Asia; a preference for sons arises in societies with distorted property rights, one in which parents, in effect, own their sons but not their daughters. Inheritance often goes to a son, parents as they get older may rely on economic support by sons. The Western rate of infanticide has dropped by more than three orders of magnitude. Criminalization has played a part, so too has more readily available and efficient contraception. Additionally, the rate of abortion is falling world-wide; the exception is in India and Western Europe where rates were lowest to begin with.
Gay rights. Through history, homosexuals have been subject to violence from fellow citizens and/or laws against homosexual acts and behaviour. Homosexual orientation appears to be inborn, and genes may play a part. In traditional and modern societies, intolerance can erupt in violence. Today homosexuality has been legalised in almost 120 countries, but is illegal in another 80 and punishable by death in various countries.
The Humanitarian revolution came out of the ‘republic of letters’. What went wrong in the Islamic world may have been a rejection of the printing press and a resistance to books and the ideas they contain. The spread of ideas can lower violence by debunking ignorance and superstition, increasing the adoption of the viewpoints of people unlike ourselves, and technological and moral progress.
Inner Demons
Violence is to some extent innate in humans. The most violent stage in life is toddlerhood, but they are socialised over the years to restrain themselves. People may fantasise about killing others and many watch violent films.
The concept of ‘pure evil’ is a myth. Most of the harm people visit on one another comes from motives that are found in every normal person. Much of the decline in violence comes from people acting on these motives less often, less fully or in fewer circumstances. While there are evil people in the world (e.g. sadistic psychopaths and narcissistic despots) there are also heroes. Much of the decline in violence seems to have come from changes in the times. Despots died and were not replaced; oppressive regimes went out of existence without fighting to the bitter end.
Scientists’ best guess is that testosterone does not make men aggressive across the board but prepares them for a challenge of dominance. Violence is a problem of too much self-esteem rather than too little.
Developed countries with mixtures of ethnic groups have better track records of ethnic non-violence. Groups may get on each other’s nerves, but they don’t kill each other. It helps if someone who attacks another group is punished by his own community – the victimized group see it as a one-on-one crime not a first strike in a group-on-group war. Things get ugly when intermingled ethnic groups long for states of their own, keep long memories of harms committed by neighbours’ ancestors while being unrepentant for harms committed by their own, and live under poor governments that mythologise one group’s glorious history while excluding others from the social contract.
Revenge is a futile exercise but the urge for vengeance is a major cause of violence. It requires the disabling of empathy. Its biological function is deterrence. The best strategy is co-operate first and until a partner defects, then defect; if the adversary switches to cooperation, then co-operate. Revenge cycles occur because people consider the harms they inflict to be justified and forgettable and the harms they suffer to be unprovoked and grievous. Conciliatory gestures can on occasion avert cycles of revenge. Success depends not only on symbolic gestures but costly ones for the apologist. Gestures are more effective in ending civil wars than international ones. A common denominator for success was a set of conciliation rituals that implemented a symbolic and incomplete justice rather than perfect justice or none at all (e.g. the South African restorative justice that involved uncompromised truth telling and acknowledgement of harm, an explicit rewriting of people’s social identities and incomplete justice – being able to draw a line under the past.
Ideologies account for the big body counts in history. Means-ends reasoning becomes dangerous when the means to a glorious end include harming human beings. How can we explain extraordinary popular delusions and the madness of crowds? Groups exhibit certain characteristics. Polarisation – a group with similar opinions will become more similar to each other and more extreme as well. Obtuseness – groups are apt to tell their leaders what they want to hear, to supress dissent, to censor private doubts and filter out evidence that contradicts an emerging consensus. Animosity between groups – groups take on an identity of their own in people’s minds and individual’s desire to be accepted within a group, and to promote its standing in comparison to other groups, can override better judgement.
People take their cues on how to behave from other people – thus bystanders to an atrocity often get caught up in the looting, gang rapes and massacres. Another phenomenon is the spiral of silence, where each member of a group goes along with certain actions because they think everyone else in the group wants to do them. This can set off cascades of false compliance and false enforcement that saturate a whole society. People can also excuse themselves by explain their actions as provoked, justified, involuntary or inconsequential.
There is no cure for ideology because it emerges from many of the cognitive processes that make us smart.  One vaccine is an open society in which people and ideas move freely and no one is punished for airing dissenting views, including those that seem heretical to political consensus.
Better Angels
Empathy, self-control, morality and taboo, and, most importantly, reason.
Empathy is a circle that may be stretched, but its elasticity is limited by kinship, friendship, similarity and cuteness (the geometry of the juvenile face). It reaches breaking point long before it encircles the full set of people that reason tells us should fall within our moral concern.
Self-control may be strengthened but it can only prevent the harms for which we ourselves harbour inner temptations. There are moments in life where we should do one’s thing – reason tells us what those moments are: times when doing your thing does not impinge on other people’s freedom to do their thing.
The moral sense offers three ethics that can be assigned to social roles and resources. But most applications of the moral sense are not particularly moral but rather tribal, authoritarian or puritanical, and it is reason that tells us which of the other applications we should entrench as norms.
Morality (philosophy) is distinct from human moral sense (psychology). People can be mistaken about their moral convictions. Moral sense is a distinctive mode of thinking about an action, not just the avoidance of the action. There are important psychological distinctions between actions deemed immoral (killing is wrong) rather than disagreeable (I hate cauliflower), unfashionable (bell-bottoms are out) or imprudent (don’t scratch mosquito bites). Moralized beliefs are actionable – people don’t need to be paid to refrain from murdering someone. Moralized infractions are punishable. If murder is wrong, the murderer must be punished. Many moral convictions operate as norms and taboos rather than as principles. Often people have an instant intuition that an action is immoral but cannot successfully explain why. Moral norms, even when unexplainable can be effective brakes on violent behaviour.
Haidt came up with five moral foundations: (1) in-group loyalty, (2) authority / respect, (3) fairness / reciprocity, (4) harm / care, and (5) purity / sanctity. No society defines everyday virtue and wrongdoing by the Golden Rule; instead morality consists in respecting or violating one of the relational models (ethics or foundations): betraying, exploiting, subverting a coalition, contaminating oneself or one’s community, defying or insulting a legitimate authority, harming someone without provocation, taking a benefit without paying the cost, peculating funds or abusing prerogatives.
Cultures often differ. One society that allows land to be bartered and sold is shocked that another society does the same with brides. In some societies a killing is avenged by the victim’s kinsmen, in others a blood payment is made, and in still others it is punished by the state.
Once a society has a degree of civilization in place, it is reason that offers the greatest hope for further reducing violence.
On Angels’ Wings
SP feels gratitude at the decline rather than optimism as the future will always be uncertain but research indicates that violence has declined up to the present. There is no grand unified theory, but the various processes and the rights revolutions have all played their part.
Some forces that might be thought to be important in the decline do not consistently reduce violence. (1) Weaponry – the technology has changed the course of history many times, makes deterrence credible and multiplies the destructive power of certain antagonists. While the technology steadily improved, the rates of violence do not match. (2) Resources and power – the idea that people fight over finite resources. The most destructive episodes of violence arose from ideologies. (3) Affluence – tight correlations between affluence and non-violence are hard to find. Nor does violent crime closely track economic indicators. However, the likelihood that a country will be torn by violent civil unrest starts to soar as its annual per capita income falls below $1,000 (2010). People may be deprived of nutrition and healthcare, and lack decent schools, police and governments. (4) Religions. Little good has come from ancient tribal dogmas and religious ideologies have often instigated violence in the past. At the same time, particular religious movements at certain times in history have contributed to the decline in violence.
The Pacifist’s Dilemma – this is a variation on the psychological Prisoner’s Dilemma model. Peace is the best outcome for both sides and war the worst. If one side attacks and the other does not respond, all the advantage goes to the attacker. Each side has to be aggressive enough not to be a sitting duck for its adversary. (1) Leviathan – a state that uses a monopoly on force to protect its citizens from one another seems to be the most consistent violence reducer, by imposing a cost on the aggressor that is large enough to cancel out his gains. (2) Gentle commerce does not eliminate the disaster of being defeated; it eliminates the adversary’s incentive to attack. (3) Feminization. Violence is mainly committed by men, especially young men. Historically women have taken the leadership in pacifist and humanitarian movements out of proportion to their influence in other political institutions of the time. Societies in which women get a better deal, both traditional and modern, tend to have less organized violence. Social and sexual arrangements that favour the interests of women tend to drain the swamps where violent male-on-male competition proliferates. Getting married reduces a man’s testosterone and their likelihood of a life of crime. Unpoliced all-male social milieus are almost always violent. Female infanticide skews the male-female ratio and leads to large numbers of unattached men. (5) Living in a more cosmopolitan society in contact with a diverse sample of other people helps us see other people’s points of view. (6) Reason – we can now look at situations with an observer’s viewpoint.
Nostalgia for a peaceable past is a delusion. Native peoples had rates of death from warfare that were greater than our world wars and past centuries used torture and extreme physical forms of punishment for what we now view as petty crime. While human nature can lead us into violence, it also provides motives to move into peace.
