Not Born Yesterday, by Hugo Mercier

In 2017, Collins Dictionary crowned ‘fake news’ its word of the year.

Collins’ entry can be credited to two unforgettable events that defined 2016: the decision taken by the United Kingdom to leave the European Union, and the election of Donald J. Trump as President of the United States. Dismayed and disoriented by the outcome of these votes, elites on both sides of the Atlantic were quick to say misleading statistics and outright lies precipitated these political earthquakes.

Like the coronavirus itself, misinformation has also exploded during the pandemic. When COVID began permeating our borders, the head of the World Health Organisation warned that “we’re not just fighting a pandemic; we’re fighting an infodemic”.

This raises the question: how impactful is misinformation generally, and are we really as vulnerable to propaganda as pundits make us out to be?  Not quite, argues French cognitive scientist Hugo Mercier in his new book, Not Born Yesterday: The Science of Who We Trust And What We Believe. Rather than being easily duped, Mercier argues that, ironically, we are not as gullible as we’ve been led to believe.

The case against gullibility

For many, Mercier’s argument will seem rather odd. Following the atrocities committed during World War Two, social psychologists have spent the past 70 years detailing the various ways we frail humans are vulnerable to social influence and persuasion. Some of social psychology’s most infamous experiments suggest that we are all natural conformists, forming our beliefs and altering our behaviour in order to fit in with the group and be in our bosses’ good books.

Despite the case for gullibility seeming an easy verdict, Mercier objects, stating that the case is far from settled. Rather than being gullible, Mercier argues, each of us come fully equipped with mental hardware, an ‘open vigilance’ system, that, most of the time, can correctly determine who we can trust, and what is ultimately true.

Viewed through the lens of evolutionary biology, Mercier argues that pure gullibility would be too easily taken advantage of by unscrupulous actors, and thus isn’t an evolutionarily stable strategy. “What should be clear in any cases is that we cannot afford to be gullible”, Mercier writes. “If we were, nothing would stop people from abusing their influence, to the point where we would be better off not paying any attention at all to what others say, leading to the prompt collapse of human communication and cooperation.”

Despite our bullshit detectors working well most of the time, Mercier argues that we’re prone to making mistakes when we’re navigating new environments that evolution hasn’t fully equipped us to deal with. What does this mean? Mercier argues that the prevalence of conspiracy theories and antiscientific beliefs can be explained, at least in part, by how intuitive these ideas are.

Take vaccines for example. Most of us have no clue how vaccines work, and the idea of injecting your healthy child with an alien substance can ring alarm bells. “All our intuitions about pathogens and contagion scream folly.” Despite the remarkable successes of vaccination programmes over the past century, communicating the effectiveness and safety of vaccines clearly remains one of the scientific communities’ thorniest issues. “In the absence of strong countervailing forces”, Mercier writes, “it doesn’t take much persuasion to turn someone into a creationist anti-vax conspiracy theorist.”

Mass persuasion

Mercier documents the astronomical funds paid for Western political campaigns, with the US presidential election taking centre stage. Given the mountains of money ploughed into these political campaigns, you would expect a commensurable return on investment. However, you may be short changed. Mercier argues that the scientific research on whether political campaigns can sway public opinion and win elections has produced surprisingly ambiguous results.

Rather than being able to socially engineer the masses’ political preferences, Mercier argues propagandists can only craft messages that already resonate with the public. “With a bit of work, they will be able to affect the audience at the margin, on issues for which the audience is ambivalent or had weak opinions to start with. Yet many have granted prophets the power to convert whole crowds, propagandists the ability to subvert entire nations, campaigners the skill to direct electoral outcomes, and advertisers the capacity to turn us all into mindless consumerists.”

Joseph Goebbels, the Nazi Propaganda Minister, is hailed as one of history’s master manipulators. Generally speaking, historians hold mixed views on the potency of Nazi propaganda. Provocatively, Mercier proclaims that essentially no persuasion took place in Nazi Germany. Rather, Mercier suggests that Hitler and his henchmen road on a ticket to heal the humiliations that Germany endured in the aftermath of World War One.

As stated by Mercier:

The power of demagogues to influence the masses has been widely exaggerated. . . If one steps back for a moment it soon becomes clear that what matters is the audience’s state of mind and material conditions, not the prophets’ power of persuasion. Once people are ready for extreme actions, some prophet will rise and provide the spark that lights the fire.

If propaganda is so staggeringly ineffective, why do millions of people living under authoritarian regimes act like they’ve been brainwashed? The answer, according to Mercier, is simple. Authoritarian regimes that plaster billboards with propaganda also closely surveil their citizens, and crush any whiff of dissent. Given their plight, it is entirely understandable why people living under repressive regimes would want to keep their mouths shut, out of fear for their personal and family’s safety.

Mercier hammers the point home:

Failure to perform the Nazi salute was perceived as a symbol of ‘political nonconformism’, a potential death sentence. In North Korea, any sign of discontent can send one’s entire family to prison camps. Under such threats, we cannot expect people to express their true feelings. Describing his life during the Cultural Revolution, a Chinese doctor remembers how “to survive in China you must reveal nothing to others”. Similarly, a North Korean coal miner acknowledged, “I know that this regime is to blame for our situation. My neighbour knows our regime is to blame. But we’re not stupid enough to talk about it.”

If repression explains acquiescence in authoritarian regimes, why do seas of people in freer societies also act like they’ve been indoctrinated? According to Mercier, professing bizarre beliefs isn’t necessarily a symptom of gullibility. Rather, jarring public declarations can serve as an oath of loyalty.

Take overinflated compliments. Mercier argues that domineering leaders don’t fish for compliments because they actually believe the lavish praise heaped onto them. Rather, excessive flattery can serve as a reliable signal of commitment to his or her reign. Counterintuitively, the more over the top and outrageous the flattery is, the more effective it can be. Why? Because the orator is demonstrating a willingness not only to burn serious social capital, but also to burn bridges with other groups they may be members of— thereby credibly signalling their allegiance to the cause.

It’s hard to believe that people would boldly pronounce absurd or repugnant views for these reasons, but loudly broadcasting outlandish views is precisely what is required to pledge one’s loyalty (say, that Hillary Clinton ran a child-sex ring out of a local pizzeria). With this, Mercier argues we shouldn’t always assume that people actually hold the batshit beliefs they regurgitate.

“People aren’t stupid”, Mercier writes. “As a rule, they avoid making self-incriminating statements for no reason. These statements serve a purpose, be it to redeem oneself or, on the contrary, to antagonise as many people as possible. By considering the functions of self-incriminating statements, we can react to them more appropriately.”

Psychological operations

With growing alarmism over the proliferation of misinformation, Mercier’s sceptical inquiry into credulity is both refreshing and somewhat reassuring. Rather than misinformation causing people to believe absurd things, Mercier argues that this account gets causality backwards. Internet trolls are not so much persuaded by misinformation, but rather, they consume and share it to attack and infuriate their political foes.

Although Mercier makes a strong case for the limited role gullibility plays in our digestion of information, I still have my doubts. Take disinformation pumped out by the Kremlin. Written before Putin launched his ‘special military operation’, Mercier claims that Russian propaganda in Ukraine succeeds modestly when preaching to the choir, and backfires when targeting Russia’s opponents. However, I suspect the Kremlin’s firehose of falsehoods has been more impactful than this.

Whilst it’s unlikely that the majority of Russians buy Putin’s torrent of lies, the core narrative that Western nations are the real aggressors in this war clearly holds sway in Russia. Mercier stresses that public opinion research conducted in autocratic regimes cannot be trusted (if you might be thrown in jail or murdered for criticising your government, I’m sure you’d also keep schtum). However, clever experiments allow people to indirectly express their true preferences. A month after Russian tanks began rolling into Ukraine, researchers using these innovative methods found widespread support for the invasion amongst Russians.

Perhaps there’s another layer of this onion that we need to peel. In his new book The Story Paradox, Jonathan Gottschall argues that it is stories that hold the main sway over our hearts and minds, rather than postulates of factual information. Whilst stories help bind groups of people together, Gottschall reveals the dark side of storytelling, warning that stories can fuel hostilities and tear societies apart. In contrast to factual claims, stories are a potent form of persuasion that pack lots of baggage into little packages, and therefore cannot be easily evaluated through fact checking.

One could argue that Mercier underestimates the dangers of modern information warfare. But of course, any attempt at questioning the veracity of open vigilance would make Mercier proud. If you try to argue against open vigilance, you lose the battle the moment you show up.

Rebuilding trust

Stepping back, what should we do with this knowledge? Before gossiping with a friend or hitting retweet, Mercier encourages us to ask ourselves what the practical consequences of sharing these rumours are, and whether the actions that follow would land us in hot water. By anticipating the consequences of our actions, we are less likely to be part of the problem. To be part of the solution, Mercier says we should penalise those who spread false rumours, or at the very least, deny them kudos for doing so.

Whilst social media giants have been getting a good bashing from politicians on both sides of the aisle, Mercier and his colleagues’ research suggests that, when it comes to the dissemination of misinformation, social media is not the problem per se. False rumours have been told since the dawn of human language, and there are arguably greater societal forces crashing over us that are powering political polarisation within Western democracies.

The take-home message of Not Born Yesterday is that, contrary to what many TED Talk gurus will tell you, influencing people is incredibly difficult. Far from being too trusting, Mercier argues that, generally speaking, we don’t trust enough. In other words, we tend to hold our guards up, where we’d benefit from lowering our defences more often than not. With this, Mercier encourages us to give the man in the street the benefit of a doubt, and to be more trusting of experts.

Of course, it takes two to tango. For experts’ opinions to carry weight, trust needs to be nurtured and sustained. To curb the spread of conspiracy theories, Mercier suggests the best strategy isn’t employing an army of fact-checkers, but rather, rebuilding trust in our key institutions (say, by passing strong laws against corruption). Trust is the glue that binds society together, and as the cliche goes, building a solid house starts with a strong foundation.

The Social Instinct, by Nichola Raihani

The pandemic has been a stark reminder of just how much we rely on one another. Like plagues of the past, the novel coronavirus has exploited our social nature. But our sociality is also our Get Out of Jail Free card.

Billions of people complying with strict lockdowns and the race to roll-out COVID-19 vaccines in record time are examples of our extraordinary ability to cooperate. This begs the question: why do we cooperate with each other in the first place?

In her new book The Social Instinct: How Cooperation Shaped the World, Nichola Raihani claims that this may be the most pressing scientific question of our time. To get to the bottom of this, Raihani takes us on an intellectual journey, chronicling some of planet Earth’s most successful social species.

The ‘we’ in ‘me’

Nichola Raihani is a professor of psychology at University College London, who actually trained as a zoologist (making her a rare breed of psychologist). Unearthing exactly what humans do and do not have in common with other animals has been the mainstay of Raihani’s scientific career.

Whether it’s the Taj Mahal or the International Space Station, staggering feats of human cooperation are clear for all of us to see. “Every human achievement we can think of, from the trifling to the truly magnificent, relies on cooperation”, Raihani writes. “From the most mundane of activities, like a morning commute, to our most tremendous achievements, such as sending rockets into space. Cooperation is our species’ superpower.”

Invisible to the naked eye is the vast array of cooperation that takes place at microscopic levels, even under our own skin. In The Social Instinct, Raihani reminds us that we are multicellular organisms, composed of trillions of cells working around the clock to keep us alive and kicking.

To let this sink in, Raihani invites us to look in the mirror and see ourselves as a Russian doll.

You are you on the outside, but this external appearance isn’t all there is. If you prise the outer shell open, you’ll find another version of you looking inside, which itself contains another version and another within. You are simultaneously an individual and a collective. Your body is made up of trillions of cells- around 37.2 trillion to be precise. For perspective that’s more than 5,000 times the number of people on earth. Most cell types contain forty-six chromosomes and each of these accommodates genes, ranging in number from a few hundred to many thousands.

From this perspective, Raihani argues that the most pivotal moments in human history were not the dawn of agriculture or the invention of the wheel. Rather, they were a coalescing of chance events millions of years ago that led to our multicellular existence.

This expansionist view of cooperation explains many wonders of the natural world, including how social insects appear to morph into superorganisms. Like separate parts of a car, the vast array of roles social insects play only really makes sense when we understand the overarching ‘vehicle’, which in this case is the insect’s colony. According to Raihani, social insects’ colonies mirror our multicellular bodies, where the Queen is akin to egg-producing ovaries, and the sterile workers resemble cells in our bodies responsible for general maintenance and repair.

Some public intellectuals also describe human societies as a form of superorganism, arguing that our ‘hive-like’ civilisations are the products of evolutionary forces clashing at higher levels of organisation. Despite the parallels, Raihani pours cold water on the idea that human groups resemble insect colonies. To make her case, Raihani draws lessons from everyone’s favourite business TV show: The Apprentice.

There is a fundamental difference between groups that are formed on the basis of high relatedness, and those whose members interests only align because of happenstance… On The Apprentice, goodwill rapidly evaporates when contestants find themselves in the losing team. When there is no rival team to unite against, a contestant’s tenure in the competition depends on their ability to outmanoeuvre their teammates. A familiar pattern usually results: people swiftly turn on one another, erstwhile allies become vicious rivals. Insults fly around the room, as contestants tried to absolve themselves of blame while incriminating their useless colleagues. When between-group competition is no longer relevant, then competition within the group becomes much more apparent. 

Although Raihani casts doubt on natural selection acting on groups of humans, she seems to tacitly endorse a new variant of the theory called ‘cultural group selection’. After all, how did a hominid species that evolved for life in small groups go on to build chiefdoms, nation states and corporations?

Social living

Others see our humanity reflected in the faces of our primate cousins. Chimpanzees and bonobos are our closet living relatives on the evolutionary tree of life, where we share over 98% of our DNA with them. The similarities between us and these great apes are striking. That said, Raihani convincingly argues that comparing ourselves to these primates can only reveal so much about us. How come?

Most of the food early humans ate had to be hunted or gathered, which is essentially impossible to do alone. Therefore, our distant ancestors had to band together if they wanted to avoid starvation. Other primate species didn’t face this pressure. Gorillas essentially live in ‘giant salad bowls’, and chimpanzees mainly snack on fruits. Their ‘fast food’ meant these primates didn’t need to collaborate to survive, which narrowed their evolutionary strategy. In contrast, we humans had no choice but to cooperate not only to eat, but to teach each other critical life skills and to raise our helpless infants.

In The Social Instinct, Raihani details the rich social lives of animals she’s studied intimately, such as the cleaner fish that roam the Great Barrier Reef. Although the similarities between us and these exotic creatures may not appear obvious, we apparently have a surprising amount in common: world-class cooperation. These cleaner fish essentially operate underwater ‘hairdressers’, where male and female cleaners frequently do business together. Raihani and her colleagues have shown that if a female cleaner mistreats a client by biting them in no-go areas, their male partners will punish them. Despite male cleaners acting like domineering arseholes (they also cheat), Raihani argues this sort of behaviour resembles ‘third party punishment’ in humans, which is one of the building blocks of large-scale societies.

Although The Social Instinct is in many respects a celebration of cooperation, it’s evident that competition can also lead to good in the world. For example, Raihani and her colleague Sarah Smith trawled through Just Giving’s fundraising pages of people running the London Marathon, with the hunch that Charles Darwin’s grand theory of sexual selection may help explain why people bother donating to charity in the first place. They found that if an attractive woman had previously received a generous donation from a man, other men would subsequently try to outcompete one other by posting larger donations on her fundraising page (I know, shocking).

This is what evolutionary psychologists call ‘competitive altruism’, where people behave altruistically because of the benefits that come with flaunting one’s virtue. Raihani suggests these tournaments are the human equivalent of the peacock’s tail. But instead of showing off their physical prowess, these men are signalling their generosity (or rather, they’re flashing their stacks of cash).

The renegades within

Just as competition can be a force for good, cooperation also has a dark side. Where there is cooperation, cheaters and shirkers lurk in the shadows. At the microscopic level, this truism can help us understand the scourge of cancer. Cancers are essentially renegades within our multicellular bodies. They are cheating cells that ignore instructions, refuse to cooperate, and proliferate to the detriment of our health.

Seen from another angle however, cancerous cells are actually cooperating with one another. Although cancers disrupt their cellular societies, they band together to further their own selfish interests, however suicidal their mission may be. This reveals the paradox of cooperation etched in The Social Instinct. “Cooperation and competition are simply two sides of the same coin”, Raihani writes. “What looks like cooperation through one lens will often be felt as competition through another.”

Scientists are converging on this understanding of cooperation as a way to outcompete rival groups. Although this theoretical breakthrough enriches our understanding of cooperation, it also reveals an uncomfortable truth: if cooperation is a way to get ahead, then a corollary of this is that cooperation usually has victims. “In fact, cooperation without victims is the most difficult kind to achieve”.

This truth bomb helps us make sense of the corruption that plagues societies across the world. We can view corruption as a form of cooperation where the goodies go to our nearest and dearest, which subsequently undermines the integrity of our formal institutions. Preferentially hiring a member of your family for a job or greasing the palm of an executive to secure a lucrative contract are both cooperative acts, Raihani argues, as they both involve helping and trust. But of course, it is society at large that ends up footing the bill.   

As stated by Raihani:

If someone were to ask you whether it would be acceptable to lie in court to exonerate a family member, what would you say? What about if you were asked whether you had a moral duty to hire the best candidate for a job rather than a less qualified friend? Answers to these sorts of questions are neither straight forward nor universally endorsed, because cooperating at one scale is often traded off against cooperation at another. Our sense of what is moral or immoral depends on how we feel these competing interests ought to be balanced. To put it put this another way, one might mistrust someone who ‘always helps his friends’. But a similarly damning accusation can be levelled at someone who ‘doesn’t help their friends’.

These different scales of cooperation also help explain the setbacks of the global vaccination programme. Few politicians would disagree with COVAX’s maxim that ‘no one is safe until everyone is safe’. Yet rich countries have essentially gobbled up the globe’s supplies of COVID-19 vaccines, and are prioritising booster shots for their citizens over immunising the rest of the world. To put it another way, intense cooperation within their borders has come at the expense of poorer nations– which inadvertently prolongs the pandemic and makes all of us less safe.

This double-edged nature of cooperation, Raihani argues, is the essential ingredient and also the biggest threat to humanity’s success. “Our supreme commitment to cooperation is the key to solving the massive global problems we now face”, Raihani writes. “But it is our ability to cooperate that might also be our eventual downfall.”

Think global, act local

The human population will soon pass the 8 billion mark. This is an extraordinary achievement for a primate that is physically weak and not exceptionally bright either. Cooperation is undoubtedly a key element of our success, and Raihani credits our social instincts for our very existence. That said, our domination of planet Earth forces us to transcend our social instincts.

The problems humanity faces in the 21st century are daunting, and require greater global cooperation than has ever been mustered. Despite the chaos created by the novel coronavirus, Raihani states that pandemics are far from our only challenge. For example, global warming and the mass die-off of species are two devastating own goals that humanity has scored. And although the world’s nuclear stockpile has decreased dramatically since the peak of the Cold War, there are still enough nuclear weapons to blow ourselves to smithereens.

We have right to be concerned about the world our children will inherit. However, Raihani argues that we must not lose hope. Unlike any other creature on Earth, human ingenuity and adaptability allows us to work around the laws of nature and to crawl our way out of sticky social dilemmas. “We are not simply stuck with the games that nature gives us: we can change the rules.”

To overcome these seemingly insurmountable challenges, Raihani says we need to ‘think global and act local’. This catchphrase was coined by the late Elinor Ostrom, who challenged conventional economic thinking and proved that the ‘tragedy of the commons’ can be overcome with hybrid forms of governance. Acknowledging the magnitude of her contributions, Ostrom was awarded the Nobel Prize in economics.

There is almost a fairy-tale to be told about cooperation, Raihani concludes. “If used well it will deliver riches, but in the wrong hands or used in the wrong ways, it will bring ruin”. The decisions our leaders make over the coming decades will determine if this story has a happy-ending, or serves as a cautionary tale for future civilisations.
