Humankind Read online

  At the same time, it’s an idea that’s legitimised by virtually every branch of science. One that’s corroborated by evolution and confirmed by everyday life. An idea so intrinsic to human nature that it goes unnoticed and gets overlooked.

  If only we had the courage to take it more seriously, it’s an idea that might just start a revolution. Turn society on its head. Because once you grasp what it really means, it’s nothing less than a mind-bending drug that ensures you’ll never look at the world the same again

  So what is this radical idea?

  That most people, deep down, are pretty decent.

  I don’t know anyone who explains this idea better than Tom Postmes, professor of social psychology at the University of Groningen in the Netherlands. For years, he’s been asking students the same question.

  Imagine an airplane makes an emergency landing and breaks into three parts. As the cabin fills with smoke, everybody inside realises: We’ve got to get out of here. What happens?

  •On Planet A, the passengers turn to their neighbours to ask if they’re okay. Those needing assistance are helped out of the plane first. People are willing to give their lives, even for perfect strangers.

  •On Planet B, everyone’s left to fend for themselves. Panic breaks out. There’s lots of pushing and shoving. Children, the elderly, and people with disabilities get trampled underfoot.

  Now the question: Which planet do we live on?

  ‘I would estimate about 97 per cent of people think we live on Planet B,’ says Professor Postmes. ‘The truth is, in almost every case, we live on Planet A.’1

  Doesn’t matter who you ask. Left wing or right, rich or poor, uneducated or well read – all make the same error of judgement. ‘They don’t know. Not freshman or juniors or grad students, not professionals in most cases, not even emergency responders,’ Postmes laments. ‘And it’s not for a lack of research. We’ve had this information available to us since World War II.’

  Even history’s most momentous disasters have played out on Planet A. Take the sinking of the Titanic. If you saw the movie, you probably think everybody was blinded by panic (except the string quartet). In fact, the evacuation was quite orderly. One eyewitness recalled that ‘there was no indication of panic or hysteria, no cries of fear, and no running to and fro’.2

  Or take the September 11 2001 terrorist attacks. As the Twin Towers burned, thousands of people descended the stairs calmly, even though they knew their lives were in danger. They stepped aside for firefighters and the injured. ‘And people would actually say: “No, no, you first,”’ one survivor later reported. ‘I couldn’t believe it, that at this point people would actually say “No, no, please take my place.” It was uncanny.’3

  There is a persistent myth that by their very nature humans are selfish, aggressive and quick to panic. It’s what Dutch biologist Frans de Waal likes to call veneer theory: the notion that civilisation is nothing more than a thin veneer that will crack at the merest provocation.4 In actuality, the opposite is true. It’s when crisis hits – when the bombs fall or the floodwaters rise – that we humans become our best selves.

  On 29 August 2005, Hurricane Katrina tore over New Orleans. The levees and flood walls that were supposed to protect the city failed. In the wake of the storm, 80 per cent of area homes flooded and at least 1,836 people lost their lives. It was one of the most devastating natural disasters in US history.

  That whole week newspapers were filled with accounts of rapes and shootings across New Orleans. There were terrifying reports of roving gangs, lootings and of a sniper taking aim at rescue helicopters. Inside the Superdome, which served as the city’s largest storm shelter, some 25,000 people were packed in together, with no electricity and no water. Two infants’ throats had been slit, journalists reported, and a seven-year-old had been raped and murdered.5

  The chief of police said the city was slipping into anarchy, and the governor of Louisiana feared the same. ‘What angers me the most,’ she said, ‘is that disasters like this often bring out the worst in people.’6

  This conclusion went viral. In the British newspaper the Guardian, acclaimed historian Timothy Garton Ash articulated what so many were thinking: ‘Remove the elementary staples of organised, civilised life – food, shelter, drinkable water, minimal personal security – and we go back within hours to a Hobbesian state of nature, a war of all against all. […] A few become temporary angels, most revert to being apes.’

  There it was again, in all its glory: veneer theory. New Orleans, according to Garton Ash, had opened a small hole in ‘the thin crust we lay across the seething magma of nature, including human nature’.7

  It wasn’t until months later, when the journalists cleared out, the floodwaters drained away and the columnists moved on to their next opinion, that researchers uncovered what had really happened in New Orleans.

  What sounded like gunfire had actually been a popping relief valve on a gas tank. In the Superdome, six people had died: four of natural causes, one from an overdose and one by suicide. The police chief was forced to concede that he couldn’t point to a single officially reported rape or murder. True, there had been looting, but mostly by groups that had teamed up to survive, in some cases even banding with police.8

  Researchers from the Disaster Research Center at the University of Delaware concluded that ‘the overwhelming majority of the emergent activity was prosocial in nature’.9 A veritable armada of boats from as far away as Texas came to save people from the rising waters. Hundreds of civilians formed rescue squads, like the self-styled Robin Hood Looters – a group of eleven friends who went around looking for food, clothing and medicine and then handing it out to those in need.10

  Katrina, in short, didn’t see New Orleans overrun with self-interest and anarchy. Rather, the city was inundated with courage and charity.

  The hurricane confirmed the science on how human beings respond to disasters. Contrary to what we normally see in the movies, the Disaster Research Center at the University of Delaware has established that in nearly seven hundred field studies since 1963, there’s never total mayhem. It’s never every man for himself. Crime – murder, burglary, rape – usually drops. People don’t go into shock, they stay calm and spring into action. ‘Whatever the extent of the looting,’ a disaster researcher points out, ‘it always pales in significance to the widespread altruism that leads to free and massive giving and sharing of goods and services.’11

  Catastrophes bring out the best in people. I know of no other sociological finding that’s backed by so much solid evidence that’s so blithely ignored. The picture we’re fed by the media is consistently the opposite of what happens when disaster strikes.

  Meanwhile, back in New Orleans, all those persistent rumours were costing lives.

  Unwilling to venture into the city unprotected, emergency responders were slow to mobilise. The National Guard was called in, and at the height of the operation some 72,000 troops were in place. ‘These troops know how to shoot and kill,’ said the governor, ‘and I expect they will.’12

  And so they did. On Danziger Bridge on the city’s east side, police opened fire on six innocent, unarmed black residents, killing a seventeen-year-old boy and a mentally disabled man of forty (five of the officers involved were later sentenced to lengthy prison terms).13

  True, the disaster in New Orleans was an extreme case. But the dynamic during disasters is almost always the same: adversity strikes and there’s a wave of spontaneous cooperation in response, then the authorities panic and unleash a second disaster.

  ‘My own impression,’ writes Rebecca Solnit, whose book A Paradise Built in Hell (2009) gives a masterful account of Katrina’s aftermath, ‘is that elite panic comes from powerful people who see all humanity in their own image.’14 Dictators and despots, governors and generals – they all too often resort to brute force to prevent scenarios that exist only in their own heads, on the assumption that the average Joe is ruled by self-interest, just like them. br />

  In the summer of 1999, at a small school in the Belgian town of Bornem, nine children came down with a mysterious illness. They’d come to school that morning with no symptoms; after lunch they were all ill. Headaches. Vomiting. Palpitations. Casting about for an explanation, the only thing the teachers could think of was the Coca-Cola the nine had drunk during break.

  It didn’t take long for journalists to get wind of the story. Over at Coca-Cola headquarters, the phones started ringing. That same evening the company issued a press release stating that millions of bottles were being recalled from Belgian store shelves. ‘We are searching frantically and hope to have a definitive answer in the next few days,’ said a spokeswoman.15

  But it was too late. The symptoms had spread through Belgium and jumped the border into France. Pale, limp kids were being rushed off in ambulances. Within days, suspicion had spread to all Coca-Cola products. Fanta, Sprite, Nestea, Aquarius . . . they all seemed a danger to children. The ‘Coca-Cola Incident’ was one of the worst financial blows in the company’s 107-year history, forcing it to recall seventeen million cases of soft drinks in Belgium and destroy its warehoused stock.16 In the end, the cost was more than 200 million dollars.17

  Then something odd happened. A few weeks later, the toxicologists issued their lab report. What had they found after running their tests on the cans of Coke? Nothing. No pesticides. No pathogens. No toxic metals. Nada. And their tests on the blood and urine samples from hundreds of patients? Zilch. The scientists were unable to find a single chemical cause for the severe symptoms which by that time had been documented in more than a thousand boys and girls.

  ‘Those kids really were sick, there’s no doubt about that,’ said one of the researchers. ‘But not from drinking a Coke.’18

  The Coca-Cola incident speaks to an age-old philosophical question.

  What is truth?

  Some things are true whether you believe in them or not. Water boils at 100°C. Smoking kills. President Kennedy was assassinated in Dallas on 22 November 1963.

  Other things have the potential to be true, if we believe in them. Our belief becomes what sociologists dub a self-fulfilling prophecy: if you predict a bank will go bust and that convinces lots of people to close their accounts, then, sure enough, the bank will go bust.

  Or take the placebo effect. If your doctor gives you a fake pill and says it will cure what ails you, chances are you will feel better. The more dramatic the placebo, the bigger that chance. Injection, on the whole, is more effective than pills, and in the old days even bloodletting could do the trick – not because medieval medicine was so advanced, but because people felt a procedure that drastic was bound to have an impact.

  And the ultimate placebo? Surgery! Don a white coat, administer an anaesthetic, and then kick back and pour yourself a cup of coffee. When the patient revives tell them the operation was a success. A broad review carried out by the British Medical Journal comparing actual surgical procedures with sham surgery (for conditions like back pain and heartburn) revealed that placebos also helped in three-quarters of all cases, and in half were just as effective as the real thing.19

  But it also works the other way around.

  Take a fake pill thinking it will make you sick, and chances are it will. Warn your patients a drug has serious side effects, and it probably will. For obvious reasons, the nocebo effect, as it’s called, hasn’t been widely tested, given the touchy ethics of convincing healthy people they’re ill. Nevertheless, all the evidence suggests nocebos can be very powerful.

  That’s also what Belgian health officials concluded in the summer of 1999. Possibly there really was something wrong with one or two of the Cokes those kids in Bornem drank. Who’s to say? But beyond that, the scientists were unequivocal: the hundreds of other children across the country had been infected with a ‘mass psychogenic illness’. In plain English: they imagined it.

  Which is not to say the victims were pretending. More than a thousand Belgian kids were genuinely nauseated, feverish and dizzy. If you believe something enough, it can become real. If there’s one lesson to be drawn from the nocebo effect, it’s that ideas are never merely ideas. We are what we believe. We find what we go looking for. And what we predict, comes to pass.

  Maybe you see where I’m going with this: our grim view of humanity is also a nocebo.

  If we believe most people can’t be trusted, that’s how we’ll treat each other, to everyone’s detriment. Few ideas have as much power to shape the world as our view of other people. Because ultimately, you get what you expect to get. If we want to tackle the greatest challenges of our times – from the climate crisis to our growing distrust of one another – then I think the place we need to start is our view of human nature.

  To be clear: this book is not a sermon on the fundamental goodness of people. Obviously, we’re not angels. We’re complex creatures, with a good side and a not-so-good side. The question is which side we turn to.

  My argument is simply this: that we – by nature, as children, on an uninhabited island, when war breaks out, when crisis hits – have a powerful preference for our good side. I will present the considerable scientific evidence showing just how realistic a more positive view of human nature is. At the same time, I’m convinced it could be more of a reality if we’d start to believe it.

  Floating around the Internet is a parable of unknown origin. It contains what I believe is a simple but profound truth:

  An old man says to his grandson: ‘There’s a fight going on inside me. It’s a terrible fight between two wolves. One is evil – angry, greedy, jealous, arrogant, and cowardly. The other is good – peaceful, loving, modest, generous, honest, and trustworthy. These two wolves are also fighting within you, and inside every other person too.’

  After a moment, the boy asks, ‘Which wolf will win?’

  The old man smiles.

  ‘The one you feed.’

  Over the last few years, whenever I told people about this book I’ve been working on, I was met with raised eyebrows. Expressions of disbelief. A German publisher flatly turned down my book proposal. Germans, she said, don’t believe in humanity’s innate goodness. A member of the Parisian intelligentsia assured me that the French need government’s firm hand. And when I toured the United States after the 2016 presidential election, everyone, everywhere, asked me if my head was screwed on straight.

  Most people are decent? Had I ever turned on a television?

  Not so long ago, a study by two American psychologists proved once again how stubbornly people can cling to the idea of our own selfish nature. The researchers presented test subjects with several situations featuring other people doing apparently nice things. So what did they find? Basically, that we are trained to see selfishness everywhere.

  See someone helping an elderly person cross the street?

  What a show-off.

  See someone offering money to a homeless person?

  Must want to feel better about herself.

  Even after the researchers presented their subjects with hard data about strangers returning lost wallets, or the fact that the vast majority of the population doesn’t cheat or steal, most subjects did not view humanity in a more positive light. ‘Instead,’ write the psychologists, ‘they decide that seemingly selfless behaviors must be selfish after all.’20

  Cynicism is a theory of everything. The cynic is always right.

  Now, you may be thinking: wait a second, that’s not how I was raised. Where I come from we trusted each other, helped each other and left our doors unlocked. And you’re right, from up close, it’s easy to assume people are decent. People like our families and friends, our neighbours and our co-workers.

  But when we zoom out to the rest of humanity, suspicion quickly takes over. Take the World Values Survey, a huge poll conducted since the 1980s by a network of social scientists in almost a hundred countries. One standard question is: ‘Generally speaking, would you say t
hat most people can be trusted or that you need to be very careful in dealing with people?’

  The results are pretty disheartening. In nearly every country most people think most other people can’t be trusted. Even in established democracies like France, Germany, Great Britain and the United States, the majority of the population shares this poor view of their fellow human beings.21

  The question that has long fascinated me is why we take such a negative view of humanity. When our instinct is to trust those in our immediate communities, why does our attitude change when applied to people as a whole? Why do so many laws and regulations, so many companies and institutions start with the assumption that people can’t be trusted? Why, when the science consistently tells us we live on Planet A, do we persist in believing we’re on Planet B?

  Is it a lack of education? Hardly. In this book I will introduce dozens of intellectuals who are staunch believers in our immorality. Political conviction? No again. Quite a few religions take it as a tenet of faith that humans are mired in sin. Many a capitalist presumes we’re all motivated by self-interest. Lots of environmentalists see humans as a destructive plague upon the earth. Thousands of opinions; one take on human nature.

  This got me wondering. Why do we imagine humans are bad? What made us start believing in the wicked nature of our kind?

  Imagine for a moment that a new drug comes on the market. It’s super-addictive, and in no time everyone’s hooked. Scientists investigate and soon conclude that the drug causes, I quote, ‘a misperception of risk, anxiety, lower mood levels, learned helplessness, contempt and hostility towards others, [and] desensitization’.22

  Would we use this drug? Would our kids be allowed to try it? Would government legalise it? To all of the above: yes. Because what I’m talking about is already one of the biggest addictions of our times. A drug we use daily, that’s heavily subsidised and is distributed to our children on a massive scale.
