  To my parents, with gratitude

  Let us boldly contemn all imitation, though it comes to us graceful and fragrant as the morning; and foster all originality, though, at first, it be crabbed and ugly as our own pine knots.

  Herman Melville, ‘Hawthorne and His Mosses’ (1850)

  Worldly wisdom teaches that it is better for reputation to fail conventionally than to succeed unconventionally.

  John Maynard Keynes, The General Theory of Employment,

  Introduction

  On 6 September 1997, the funeral of Diana, Princess of Wales attracted a crowd of over 3 million mourners in London, as well as a worldwide TV audience of almost 3 billion. The metres-deep carpets of bouquets, poems, teddy bears and other sentimental offerings accumulating outside Buckingham Palace and Diana’s Kensington Palace home gave the twentieth century some of its most iconic images. Millions of strangers expressed extreme – if short-lived – grief about the death of a person they had never met. Why did so many individual mourners feel deeply enough to join with millions of others in expressing their collective sadness? They joined together as a grief-stricken herd, coordinated around the globe by international news media. This powerful mass hysteria seemed as unreasoning as it was uncontrollable. But was it?

  Our herding is not always histrionic. Our tendency to imitate, follow others and group together can be reasonable strategies to improve our lives and evolutionary life chances. Herding is an instinct we share with other animals too. Behavioural ecologists have observed clever copying behaviour amongst many of our close (and not so close) animal relatives. One example was uncovered by behavioural ecologists studying the behaviour of a small Australian marsupial called the quoll. Its survival was being threatened by the cane toad, introduced to Australia in the 1930s in a misguided attempt to manage the destruction of sugar cane plantations by cane beetles. To a quoll, these toads look as tasty as they are poisonous, and the quolls who scoffed them suffered fatal consequences at a speedy rate. Behavioural ecologists identified a clever solution by constructively harnessing quolls’ instincts to imitate. Small groups of quolls were trained to be ‘toad-smart’ via a form of aversion therapy. They were fed toad sausages spiked with harmless but nausea-inducing chemicals, conditioning them to avoid the toads. Groups of these toad-smart quolls were then released back into the wild: they taught their own offspring what they’d learnt. Other quolls copied these constructive behaviours through a process of social learning. As each baby quoll learnt to avoid the hazardous toads, so the chances of the survival of the whole quoll species – and not just that of each individual quoll – were improved. The quolls were saved via minimal human interference, because ecologists were able to leverage quolls’ natural imitative instincts.1

  Diana’s mourners and the toad-smart quolls illustrate that, as social animals, we clearly have strong instincts to copy and conform, a pattern of behaviour that has helped many species, including our own, to survive and prosper. But this is only half the story. Humans are not conformists always and everywhere. There are plenty of rebels and contrarians, some of whom have changed lives and history. Socrates was a famous example: he was sentenced by a jury to death by hemlock in 399 BC as punishment for refusing to worship the gods revered by his fellow Athenians, for appearing to side with the Spartans, and for embracing a role as self-appointed critic and gadfly of the Athenian state. But while Socrates ended his life as an outcast, our intellectual history was transformed by his contributions. Similarly, our modern lives would be unimaginable if history had not delivered a wide range of different characters prepared to take maverick risks: from Copernicus and Galileo through to Darwin, Crick and Watson. Via careful thought and deliberation, these and other mavericks and mavens have led us down new paths, unimaginable and contentious at the time. The consequences of the risks they took with their reputations and social standing were profound in terms of transforming the length and quality of our lives.

  Herding and anti-herding defined

  What exactly is herding? And what is its opposite? The literatures on copycats herding is vast (though there is less emphasis on contrarians) and span a wide range of subjects and contexts. With such a diversity of researchers studying herding, a universal definition is likely to be elusive. But there are three common threads that unify conceptions of herding that we can observe in ourselves and other copycats around us. First, and most obviously, herding involves imitation. Second, it is a group phenomenon: someone imitating just one other person is not herding; many people imitating one person – and many people imitating many people – is herding. Third, herding may sometimes be driven by unconscious motivations, as we shall see, but it is not random. Conscious and unconscious forces encourage us to choose to follow groups in systematic ways. Pulling all these threads together, we can define herding as a systematic choice to copy others in a group. It may benefit the self-interested individual, or it may bestow a collective advantage if individuals are joining with their fellows to support the interests of groups and/or species.

  Understanding herding copycats will also help us to understand the essence of their opposites: the contrarians. Contrarians are ‘anti-herders’, where anti-herding can be defined as a choice not to copy others in a group.2 Anti-herding is not as dissimilar from herding as we might at first imagine. Anti-herding is a group behaviour, and it is not random; but it is the mirror image of imitation because an anti-herding contrarian acts against, not in concert with, the group. Further, anti-herding shares two of the three features of herding outlined above, but with a few twists. Anti-herding is often a group phenomenon because it does not concern behaviour that is random or orthogonal to the group’s behaviour. Contrarians are not hermits. They worry what others think, but they may deliberately decide to oppose the herd – sometimes by leading the group instead of following it. Like herding, anti-herding is systematic, not random, and perhaps it is more systematic if it is driven by deliberate, conscious choices. Either way, the actions of anti-herding contrarians and herding copycats can be complementary, in both good and bad ways.

  Another key characteristic of herding is that it is social behaviour. We have evolved to be social animals, an evolutionary path that has instilled in us instincts to group
together, reinforced by the social skills learnt during infancy and childhood. We trust and cooperate with others, even with strangers many miles away from us. We are often altruistic and philanthropic, even though our kindness to others reflects a complex mix of self-interest and generosity. It is a two-way interaction. When others are kind to us, we reciprocate. And when we reciprocate we build trust, and not only with our family, friends and communities. Most of our daily activities, including our economic activities such as work and shopping, would not be possible without trust and reciprocity. All these phenomena are linked to our more outward-looking and gregarious sides. Myriad experiments from psychology, neuroscience and behavioural economics have verified our strong social instincts, instincts that are shared widely – across countries, cultures and other animal species, including our close primate cousins. What has this to do with copycats and contrarians? Copying, herding and imitating are another facet of our social nature, and our herding tendencies complement these other aspects of our sociality. Crowds of like-minded people will gather together, in a political protest for example, because they share a level of trust – in each other and in the cause or leader that they are supporting. The same people would be as reluctant to join a crowd of opponents they do not trust as they are enthusiastic to join a crowd of people they do trust. Marketers and advertisers know well that if we can be persuaded that certain celebrities are trustworthy, then we can be encouraged to follow them by buying the products they endorse. Local and communal activities – from cake sales to charity auctions – are examples of how we bring together our desires to join a group with our generous and reciprocating natures.

  Why herd?

  The behaviours exhibited by Diana’s mourners, quolls and Socrates may appear, superficially, to be different. Scratch the surface, however, and we can see they do share some commonalities in what they tell us about how and why we imitate others – and when we don’t, why we don’t. Many herding researchers from across the social and behavioural sciences have focused on capturing the social influences underlying our propensities to herd, and these can be roughly divided into the categories of informational influences and normative influences.

  Informational influences include all the ways in which we learn by gathering information from others around us. What others do, and whether they succeed, is important information we can use to our own advantage. We observe how others choose and decide and this helps us to choose and decide for ourselves. We may also be able to see how others’ choices work out for them – so we can learn from their mistakes as well as their successes. The Garissa University College attack in April 2015 was a powerful, but harrowing, example of how copying driven by social learning can save lives. Four gunmen from the al-Shabaab jihadist militant group stormed the Kenyan college. They took students hostage, showing mercy only if a student could convince them that they were Muslim by reciting a key tract from the Qur’an. Those who could not cite the relevant tract were shot. One Christian student watched what was happening to those in the line in front of her and quickly learned to memorise the tract she needed to recite in order to persuade the hostage-takers that she was a Muslim. She saved her own life through social learning, by gathering information about others’ choices and their consequences. From the perspective of her fellow Christians, this social information led her towards anti-herding, not herding; but she had learnt that copying most of the other Christians in the line ahead of her was not going to ensure her survival.

  Normative influences encompass the norms and customs that define the groups and communities around us. Our responses to normative influences are often less conscious and deliberate than our responses to informational influences. We copy others because we feel a compulsion from others around us to conform – reflecting social norms, peer pressure and groupthink. The queue, for instance, is a famously sacred British institution. Most Brits would not dream of pushing into a long queue or joining a free-for-all stampede to the front, even when it might obviously be in their best interests to do so and harmful consequences are unlikely. London’s Evening Standard reported an engaging example: 200 of Ed Sheeran’s biggest fans, who had bought tickets in an online frenzy for one of his 2017 London concerts, calmly and entirely voluntarily formed an orderly queue outside the venue without instructions. Neither physical barriers nor policing were needed.3

  Figure 1. Voluntary queuing at an Ed Sheeran concert, 2017.

  Like Sheeran’s adoring fans, and without consciously thinking about it too hard, we are aware that we will violate social norms and incite disapproval from strangers if we appear to be pushing in and prioritising our own wants at the expense of the many around us. Some of us will be happily waiting patiently in queues; others might be exerting effort in controlling aggressive instincts to push in. Either way, the queue represents a cooperative solution that minimises discomfort for the crowd.

  The different types of normative influence are diffuse and harder (if not impossible) to quantify, but they are just as important as informational influences. Possibly they are more important because they are ingrained, automatic responses that we do not consciously notice in ourselves. They can also, perhaps counterintuitively, help to explain contrarian behaviours: people who behave in unconventional ways are sometimes simply adhering to unconventional norms, shared by a small fringe of marginalised groups with which they identify.

  Consequences

  Neither rebellion nor conformity is inherently good. Neither is inherently bad. If we follow others in buying into a rising housing market, for example, we may do very well out of gains in our property’s value. If we follow others out of a collapsing football stadium, then we risk death by trampling. If we lead others out of a burning building, then we may all survive. If contrarians lead others into war, terrorism or gang violence, then they are risking others’ lives, and sometimes their own. Even in terms of universal virtues, we would find it difficult to come to a clear conclusion. Copycats and contrarians are driven by the tensions between exploiting and using the group versus belonging and contributing to the group. Copying and herding manifest themselves in a wide range of ways: individuals operating in their own self-interest; collectives of individuals working together as a team towards a shared goal; madding crowds which seem to have a life and mind of their own and in which each individual person is dispensable. And even as individuals, we are not consistent. We all have the capacity to be copycats in some situations and contrarians in others. In our social and cultural lives, whether we decide to be copycats or contrarians will be determined by our different identities, formed by different contexts and our different roles in society. Like Dr Jekyll and Mr Hyde, a person who is conventional, diligent and professional during the daytime may be more unconventional, rebellious and disruptive at night.

  Where do we begin in understanding all these complex interplays? The simplest place is by looking at what drives each of us as self-interested individuals to copy others and join groups. Economists have explored this theme extensively, focusing on how social learning and other rational motivations might encourage us to join a herd, as we shall see in chapter 1. From there we will fill in the many gaps in the simple economic model by looking across the social and biological sciences for other insights that can help to explain our copycat and contrarian natures.

  What are the implications for our everyday lives? Some are worrying. Our evolved instincts, personalities, even our aptitude for intelligence can help to explain copycat and contrarian attitudes, choices and behaviour. But those evolutionary qualities are not necessarily a good fit in today’s world. We live in an age in which we are digitally and globally interconnected in ways that could not have been imagined even a century ago, let alone when modern humans were evolving many hundreds of thousands of years in the past. Where does the group begin and end? When should we use information implicit in a group’s actions and when should we ignore it? Ancient evolved animal behaviours operating within our artificial modern world can incubate a range
of perverse behaviours, herding included. Our inclinations to copy or rebel do not always fit well with social media echo chambers, volatile stock markets, sensationalist clickbait newspaper reporting, political populism and information overload.

  In the many volumes of papers and books about herding and contrarianism, writers and researchers tend to zero in on subject-specific research questions. This book is different. It brings together insights from a broad range of studies in a multidisciplinary account. Some economic theories explore why, as self-interested individuals, we might feel inclined to herd or rebel. From psychology and sociology we can see that unconscious social influences are powerful, but copying them does not always work out well. Neuroscience, evolutionary biology and behavioural ecology can give us some understanding of where our copycat and contrarian instincts come from, and how they play out in our everyday lives. All of these insights together can answer some pressing questions. What are the origins of our copycat and contrarian instincts and inclinations? How do copycats and contrarians interact? Do our copycat and contrarian instincts equip us well in the modern world? And, perhaps the most important question of all: what can we do about it?

  Clever copying

  Are copycats clever? Or is it mindless and irrational just to do what others are doing without using our own initiative and mental energy to decide for ourselves? And how might we distinguish blind conformity from intelligent imitation? Often, we cannot easily tell the difference.

  Our everyday lives provide some examples. Imagine that you are in a meeting and you are asked to vote on an issue about which you do not feel particularly passionate or well informed. You decide to raise your hand in favour because you see a few of your colleagues doing the same. Are you being lazy? Responding to peer pressure? Perhaps. Or perhaps you are using your colleagues’ actions as an alternative source of information. You interpret their hand-raising as a signal that they know something you do not. If you knew what they know, then perhaps you would vote in favour too. In cases like this, following others is clearly not stupid, even when it involves minimal brainwork.
