Your brain on pseudoscience: the rise of popular neurobollocks

The “neuroscience” shelves in bookshops are groaning. But are the works of authors such as Malcolm Gladwell and Jonah Lehrer just self-help books dressed up in a lab coat?

An intellectual pestilence is upon us. Shop shelves groan with books purporting to explain, through snazzy brain-imaging studies, not only how thoughts and emotions function, but how politics and religion work, and what the correct answers are to age-old philosophical controversies. The dazzling real achievements of brain research are routinely pressed into service for questions they were never designed to answer. This is the plague of neuroscientism – aka neurobabble, neurobollocks, or neurotrash – and it’s everywhere.

In my book-strewn lodgings, one literally trips over volumes promising that “the deepest mysteries of what makes us who we are are gradually being unravelled” by neuroscience and cognitive psychology. (Even practising scientists sometimes make such grandiose claims for a general audience, perhaps urged on by their editors: that quotation is from the psychologist Elaine Fox’s interesting book on “the new science of optimism”, Rainy Brain, Sunny Brain, published this summer.) In general, the “neural” explanation has become a gold standard of non-fiction exegesis, adding its own brand of computer-assisted lab-coat bling to a whole new industry of intellectual quackery that affects to elucidate even complex sociocultural phenomena. Chris Mooney’s The Republican Brain: the Science of Why They Deny Science – and Reality disavows “reductionism” yet encourages readers to treat people with whom they disagree more as pathological specimens of brain biology than as rational interlocutors.

The New Atheist polemicist Sam Harris, in The Moral Landscape, interprets brain and other research as showing that there are objective moral truths, enthusiastically inferring – almost as though this were the point all along – that science proves “conservative Islam” is bad.

Happily, a new branch of the neuroscienceexplains everything genre may be created at any time by the simple expedient of adding the prefix “neuro” to whatever you are talking about. Thus, “neuroeconomics” is the latest in a long line of rhetorical attempts to sell the dismal science as a hard one; “molecular gastronomy” has now been trumped in the scientised gluttony stakes by “neurogastronomy”; students of Republican and Democratic brains are doing “neuropolitics”; literature academics practise “neurocriticism”. There is “neurotheology”, “neuromagic” (according to Sleights of Mind, an amusing book about how conjurors exploit perceptual bias) and even “neuromarketing”. Hoping it’s not too late to jump on the bandwagon, I have decided to announce that I, too, am skilled in the newly minted fields of neuroprocrastination and neuroflâneurship.

Illumination is promised on a personal as well as a political level by the junk enlightenment of the popular brain industry. How can I become more creative? How can I make better decisions? How can I be happier? Or thinner? Never fear: brain research has the answers. It is self-help armoured in hard science. Life advice is the hook for nearly all such books. (Some cram the hard sell right into the title – such as John B Arden’s Rewire Your Brain: Think Your Way to a Better Life.) Quite consistently, heir recommendations boil down to a kind of neo- Stoicism, drizzled with brain-juice. In a selfcongratulatory egalitarian age, you can no longer tell people to improve themselves morally. So self-improvement is couched in instrumental, scientifically approved terms.

The idea that a neurological explanation could exhaust the meaning of experience was already being mocked as “medical materialism” by the psychologist William James a century ago. And today’s ubiquitous rhetorical confidence about how the brain works papers over a still-enormous scientific uncertainty. Paul Fletcher, professor of health neuroscience at the University of Cambridge, says that he gets “exasperated” by much popular coverage of neuroimaging research, which assumes that “activity in a brain region is the answer to some profound question about psychological processes. This is very hard to justify given how little we currently know about what different regions of the brain actually do.” Too often, he tells me in an email correspondence, a popular writer will “opt for some sort of neuro-flapdoodle in which a highly simplistic and questionable point is accompanied by a suitably grand-sounding neural term and thus acquires a weightiness that it really doesn’t deserve. In my view, this is no different to some mountebank selling quacksalve by talking about the physics of water molecules’ memories, or a beautician talking about action liposomes.”

Shades of grey

The human brain, it is said, is the most complex object in the known universe. That a part of it “lights up” on an fMRI scan does not mean the rest is inactive; nor is it obvious what any such lighting-up indicates; nor is it straightforward to infer general lessons about life from experiments conducted under highly artificial conditions. Nor do we have the faintest clue about the biggest mystery of all – how does a lump of wet grey matter produce the conscious experience you are having right now, reading this paragraph? How come the brain gives rise to the mind? No one knows.

So, instead, here is a recipe for writing a hit popular brain book. You start each chapter with a pat anecdote about an individual’s professional or entrepreneurial success, or narrow escape from peril. You then mine the neuroscientific research for an apparently relevant specific result and narrate the experiment, perhaps interviewing the scientist involved and describing his hair. You then climax in a fit of premature extrapolation, inferring from the scientific result a calming bromide about what it is to function optimally as a modern human being. Voilà, a laboratory-sanctioned Big Idea in digestible narrative form. This is what the psychologist Christopher Chabris has named the “story-study-lesson” model, perhaps first perfected by one Malcolm Gladwell. A series of these threesomes may be packaged into a book, and then resold again and again as a stand-up act on the wonderfully lucrative corporate lecture circuit.

Such is the rigid formula of Imagine: How Creativity Works, published in March this year by the American writer Jonah Lehrer. The book is a shatteringly glib mishmash of magazine yarn, bizarrely incompetent literary criticism, inspiring business stories about mops and dolls and zany overinterpretation of research findings in neuroscience and psychology. Lehrer responded to my hostile review of the book by claiming that I thought the science he was writing about was “useless”, but such garbage needs to be denounced precisely in defence of the achievements of science. (In a sense, as Paul Fletcher points out, such books are “anti science, given that science is supposed to be  our protection against believing whatever we find most convenient, comforting or compelling”.) More recently, Lehrer admitted fabricating quotes by Bob Dylan in Imagine, which was hastily withdrawn from sale, and he resigned from his post at the New Yorker. To invent things supposedly said by the most obsessively studied popular artist of our age is a surprising gambit. Perhaps Lehrer misunderstood his own advice about creativity.

Mastering one’s own brain is also the key to survival in a dog-eat-dog corporate world, as promised by the cognitive scientist Art Markman’s Smart Thinking: How to Think Big, Innovate and Outperform Your Rivals. Meanwhile, the field (or cult) of “neurolinguistic programming” (NLP) sells techniques not only of self-overcoming but of domination over others. (According to a recent NLP handbook, you can “create virtually any and all states” in other people by using “embedded commands”.) The employee using such arcane neurowisdom will get promoted over the heads of his colleagues; the executive will discover expert-sanctioned ways to render his underlings more docile and productive, harnessing “creativity” for profit.

Waterstones now even has a display section labelled “Smart Thinking”, stocked with pop brain tracts. The true function of such books, of course, is to free readers from the responsibility of thinking for themselves. This is made eerily explicit in the psychologist Jonathan Haidt’s The Righteous Mind, published last March, which claims to show that “moral knowledge” is best obtained through “intuition” (arising from unconscious brain processing) rather than by explicit reasoning. “Anyone who values truth should stop worshipping reason,” Haidt enthuses, in a perverse manifesto for autolobotomy. I made an Olympian effort to take his advice seriously, and found myself rejecting the reasoning of his entire book.

Modern neuro-self-help pictures the brain as a kind of recalcitrant Windows PC. You know there is obscure stuff going on under the hood, so you tinker delicately with what you can see to try to coax it into working the way you want. In an earlier age, thinkers pictured the brain as a marvellously subtle clockwork mechanism, that being the cutting-edge high technology of the day. Our own brain-as-computer metaphor has been around for decades: there is the “hardware”, made up of different physical parts (the brain), and the “software”, processing routines that use different neuronal “circuits”. Updating things a bit for the kids, the evolutionary psychologist Robert Kurzban, in Why Everyone (Else) Is a Hypocrite, explains that the brain is like an iPhone running a bunch of different apps.

Such metaphors are apt to a degree, as long as you remember to get them the right way round. (Gladwell, in Blink – whose motivational selfhelp slogan is that “we can control rapid cognition” – burblingly describes the fusiform gyrus as “an incredibly sophisticated piece of brain software”, though the fusiform gyrus is a physical area of the brain, and so analogous to “hardware” not “software”.) But these writers tend to reach for just one functional story about a brain subsystem – the story that fits with their Big Idea – while ignoring other roles the same system might play. This can lead to a comical inconsistency across different books, and even within the oeuvre of a single author.

Is dopamine “the molecule of intuition”, as Jonah Lehrer risibly suggested in The Decisive Moment (2009), or is it the basis of “the neural highway that’s responsible for generating the pleasurable emotions”, as he wrote in Imagine? (Meanwhile, Susan Cain’s Quiet: the Power of Introverts in a World That Can’t Stop Talking calls dopamine the “reward chemical” and postulates that extroverts are more responsive to it.) Other recurring stars of the pop literature are the hormone oxytocin (the “love chemical”) and mirror neurons, which allegedly explain empathy. Jonathan Haidt tells the weirdly unexplanatory micro-story that, in one experiment, “The subjects used their mirror neurons, empathised, and felt the other’s pain.” If I tell you to use your mirror neurons, do you know what to do? Alternatively, can you do as Lehrer advises and “listen to” your prefrontal cortex? Self-help can be a tricky business.

Cherry-picking

Distortion of what and how much we know is bound to occur, Paul Fletcher points out, if the literature is cherry-picked.

“Having outlined your theory,” he says, “you can then cite a finding from a neuroimaging study identifying, for example, activity in a brain region such as the insula . . . You then select from among the many theories of insula function, choosing the one that best fits with your overall hypothesis, but neglecting to mention that nobody really knows what the insula does or that there are many ideas about its possible function.”

But the great movie-monster of nearly all the pop brain literature is another region: the amygdala. It is routinely described as the “ancient” or “primitive” brain, scarily atavistic. There is strong evidence for the amygdala’s role in fear, but then fear is one of the most heavily studied emotions; popularisers downplay or ignore the amygdala’s associations with the cuddlier emotions and memory. The implicit picture is of our uneasy coexistence with a beast inside the head, which needs to be controlled if we are to be happy, or at least liberal. (In The Republican Brain, Mooney suggests that “conservatives and authoritarians” might be the nasty way they are because they have a “more active amygdala”.) René Descartes located the soul in the pineal gland; the moral of modern pop neuroscience is that original sin is physical – a bestial, demonic proto-brain lurking at the heart of darkness within our own skulls. It’s an angry ghost in the machine.

Indeed, despite their technical paraphernalia of neurotransmitters and anterior temporal gyruses, modern pop brain books are offering a spiritual topography. Such is the seductive appeal of fMRI brain scans, their splashes of red, yellow and green lighting up what looks like a black intracranial vacuum. In mass culture, the fMRI scan (usually merged from several individuals) has become a secular icon, the converse of a Hubble Space Telescope image. The latter shows us awe-inspiring vistas of distant nebulae, as though painstakingly airbrushed by a sci-fi book-jacket artist; the former peers the other way, into psychedelic inner space. And the pictures, like religious icons, inspire uncritical devotion: a 2008 study, Fletcher notes, showed that “people – even neuroscience undergrads – are more likely to believe a brain scan than a bar graph”.

In The Invisible Gorilla, Christopher Chabris and his collaborator Daniel Simons advise readers to be wary of such “brain porn”, but popular magazines, science websites and books are frenzied consumers and hypers of these scans. “This is your brain on music”, announces a caption to a set of fMRI images, and we are invited to conclude that we now understand more about the experience of listening to music. The “This is your brain on” meme, it seems, is indefinitely extensible: Google results offer “This is your brain on poker”, “This is your brain on metaphor”, “This is your brain on diet soda”, “This is your brain on God” and so on, ad nauseam. I hereby volunteer to submit to a functional magnetic-resonance imaging scan while reading a stack of pop neuroscience volumes, for an illuminating series of pictures entitled This Is Your Brain on Stupid Books About Your Brain.

None of the foregoing should be taken to imply that fMRI and other brain-investigation techniques are useless: there is beautiful and amazing science in how they work and what well-designed experiments can teach us. “One of my favourites,” Fletcher says, “is the observation that one can take measures of brain activity (either using fMRI or EEG) while someone is learning . . . a list of words, and that activity can actually predict whether particular words will be remembered when the person is tested later (even the next day). This to me demonstrates something important – that observing activity in the brain can tell us something about how somebody is processing stimuli in ways that the person themselves is unable to report. With measures like that, we can begin to see how valuable it is to measure brain activity – it is giving us information that would otherwise be hidden from us.”

In this light, one might humbly venture a preliminary diagnosis of the pop brain hacks’ chronic intellectual error. It is that they misleadingly assume we always know how to interpret such “hidden” information, and that it is always more reliably meaningful than what lies in plain view. The hucksters of neuroscientism are the conspiracy theorists of the human animal, the 9/11 Truthers of the life of the mind.

Why the elites always rule

Since an Italian sociologist coined the word “elite” in 1902, it has become a term of abuse. But history is the story of one elite replacing another – as the votes for Trump and Brexit have shown.

Donald Trump’s successful presidential campaign was based on the rejection of the “establishment”. Theresa May condemned the rootless “international elites” in her leader’s speech at last October’s Conservative party conference. On the European continent, increasingly popular right-wing parties such as Marine Le Pen’s Front National and the German Alternative für Deutschland, as well as Poland’s ruling Law and Justice party, delight in denouncing the “Eurocratic” elites. But where does the term “elite” come from, and what does it mean?

It was Vilfredo Pareto who, in 1902, gave the term the meaning that it has today. We mostly think of Pareto as the economist who came up with ideas such as “Pareto efficiency” and the “Pareto principle”. The latter – sometimes known as the “power law”, or the “80/20 rule” – stipulates that 80 per cent of the land always ends up belonging to 20 per cent of the population. Pareto deduced this by studying land distribution in Italy at the turn of the 20th century. He also found that 20 per cent of the pea pods in his garden produced 80 per cent of the peas. Pareto, however, was not only an economist. In later life, he turned his hand to sociology, and it was in this field that he developed his theory of the “circulation of elites”.

The term élite, used in its current socio­logical sense, first appeared in his 1902 book Les systèmes socialistes (“socialist systems”). Its aim was to analyse Marxism as a new form of “secular” religion. And it was the French word élite that he used: naturally, one might say, for a book written in French. Pareto, who was bilingual, wrote in French and Italian. He was born in Paris in 1848 to a French mother and an Italian father; his father was a Genoese marquis who had accompanied the political activist Giuseppe Mazzini into exile. In honour of the revolution that was taking place in Germany at the time, Pareto was at first named Fritz Wilfried. This was latinised into Vilfredo Federico on the family’s return to Italy in 1858.

When Pareto wrote his masterpiece – the 3,000-page Trattato di sociologia ­generale (“treatise on general sociology”) – in 1916, he retained the French word élite even though the work was in Italian. Previously, he had used “aristocracy”, but that didn’t seem to fit the democratic regime that had come into existence after Italian unification. Nor did he want to use his rival Gaetano Mosca’s term “ruling class”; the two had bitter arguments about who first came up with the idea of a ruling minority.

Pareto wanted to capture the idea that a minority will always rule without recourse to outdated notions of heredity or Marxist concepts of class. So he settled on élite, an old French word that has its origins in the Latin eligere, meaning “to select” (the best).

In the Trattato, he offered his definition of an elite. His idea was to rank everyone on a scale of one to ten and that those with the highest marks in their field would be considered the elite. Pareto was willing to judge lawyers, politicians, swindlers, courtesans or chess players. This ranking was to be morally neutral: beyond “good and evil”, to use the language of the time. So one could identify the best thief, whether that was considered a worthy profession or not.

Napoleon was his prime example: whether he was a good or a bad man was irrelevant, as were the policies he might have pursued. Napoleon had undeniable political qualities that, according to Pareto, marked him out as one of the elite. Napoleon is important
because Pareto made a distinction within the elite – everyone with the highest indices within their branch of activity was a member of an elite – separating out the governing from the non-governing elite. The former was what interested him most.

This is not to suggest that the non-governing elite and the non-elite were of no interest to him, but they had a specific and limited role to play, which was the replenishment of the governing elite. For Pareto, this group was the key to understanding society as a whole – for whatever values this elite incarnated would be reflected in society. But he believed that there was an inevitable “physiological” law that stipulated the continuous decline of the elite, thereby making way for a new elite. As he put it in one of his most memorable phrases, “History is the graveyard of elites.”

***

Pareto’s thesis was that elites always rule. There is always the domination of the minority over the majority. And history is just the story of one elite replacing another. This is what he called the “circulation of elites”. When the current elite starts to decline, it is challenged and makes way for another. Pareto thought that this came about in two ways: either through assimilation, the new elite merging with elements of the old, or through revolution, the new elite wiping out the old. He used the metaphor of a river to make his point. Most of the time, the river flows continuously, smoothly incorporating its tributaries, but sometimes, after a storm, it floods and breaks its banks.

Drawing on his Italian predecessor Machiavelli, Pareto identified two types of elite rulers. The first, whom he called the “foxes”, are those who dominate mainly through combinazioni (“combination”): deceit, cunning, manipulation and co-optation. Their rule is characterised by decentralisation, plurality and scepticism, and they are uneasy with the use of force. “Lions”, on the other hand, are more conservative. They emphasise unity, homogeneity, established ways, the established faith, and rule through small, centralised and hierarchical bureaucracies, and they are far more at ease with the use of force than the devious foxes. History is the slow swing of the pendulum from one type of elite to the other, from foxes to lions and back again.

The relevance of Pareto’s theories to the world today is clear. After a period of foxes in power, the lions are back with renewed vigour. Donald Trump, as his behaviour during the US presidential campaign confirmed, is perfectly at ease with the use of intimidation and violence. He claimed that he wants to have a wall built between the United States and Mexico. His mooted economic policies are largely based on protectionism and tariffs. Regardless of his dubious personal ethics – a classic separation between the elite and the people – he stands for the traditional (white) American way of life and religion.

This is in stark contrast to the Obama administration and the Cameron government, both of which, compared to what has come since the votes for Trump and Brexit, were relatively open and liberal. Pareto’s schema goes beyond the left/right divide; the whole point of his Systèmes socialistes was to demonstrate that Marxism, as a secular religion, signalled a return to faith, and thus the return of the lions in politics.

In today’s context, the foxes are the forces of globalisation and liberalism – in the positive sense of developing an open, inter­connected and tolerant world; and in the negative sense of neoliberalism and the dehumanising extension of an economic calculus to all aspects of human life. The lions represent the reaction, centring themselves in the community, to which they may be more attentive, but bringing increased xenophobia, intolerance and conservatism. For Pareto, the lions and foxes are two different types of rule, both with strengths and weaknesses. Yet the elite is always composed of the two elements. The question is: which one dominates at any given time?

What we know of Theresa May’s government suggests that she runs a tight ship. She has a close – and closed – group of confidants, and she keeps a firm grip on the people under her. She is willing to dispense with parliament in her negotiation of Brexit, deeming it within the royal prerogative. Nobody yet knows her plan.

The European Union is a quintessentially foxlike project, based on negotiation, compromise and combination. Its rejection is a victory of the lions over the foxes. The lions are gaining prominence across the Western world, not just in Trumpland and Brexit Britain. Far-right movements have risen by rejecting the EU. It should come as no surprise that many of these movements (including Trump in the US) admire Vladimir Putin, at least for his strongman style.

Asia hasn’t been spared this movement, either. After years of tentative openness in China, at least with the economy, Xi Jinping has declared himself the “core” leader, in the mould of the previous strongmen Mao Zedong and Deng Xiaoping. Japan’s prime minister, Shinzo Abe, has also hardened his stance, and he was the first world leader to meet with President-Elect Donald Trump. Narendra Modi in India and Rodrigo Duterte in the Philippines are in the same mould, the latter coming to power on the back of promising to kill criminals and drug dealers. After the failed coup against him in July, Recep Tayyip Erdogan has also been cracking down on Turkey.

In Les systèmes socialistes, Pareto elaborated on how a new elite replaces the old. A, the old elite, would be challenged by B, the new, in alliance with C, the people. B would win the support of C by making promises that, once in power, it wouldn’t keep. If that sounds like the behaviour of most politicians, that is because it probably is. But what Pareto was pointing out was how, in its struggle for power, the new elite politicised groups that were not political before.

What we know of Trump supporters and Brexiteers is that many feel disenfranchised: the turnout in the EU referendum could not have been greater than in the 2015 general election otherwise, and significant numbers of those who voted for Trump had never voted before. There is no reason to think that they, too, won’t be betrayed by the new leaders they helped to bring to power.

In the last years of his life, Pareto offered a commentary on Italy in the 1920s. He denounced the state’s inability to enforce its decisions and the way that Italians spent their time flaunting their ability to break the law and get away with it. He coined the phrase “demagogic plutocracy” to characterise the period, in which the rich ruled behind a façade of democratic politics. He thought this particularly insidious for two reasons: those in power were more interested in siphoning off wealth for their personal ends than encouraging the production of new wealth, and consequently undermined national prosperity (remember Pareto’s training as an economist); and, as the demagogic elites govern through deceit and cunning, they are able to mask their rule for longer periods.

Much has been made of Trump’s “populism”, but the term “demagogic plutocrat” seems particularly apt for him, too: he is a wealthy man who will advance the interests of his small clique to the detriment of the well-being of the nation, all behind the smokescreen of democratic politics.

There are other ways in which Pareto can help us understand our predicament. After all, he coined the 80/20 rule, of which we hear an intensified echo in the idea of “the One Per Cent”. Trump is a fully paid-up member of the One Per Cent, a group that he claims to be defending the 99 Per Cent from (or, perhaps, he is an unpaid-up member, given that what unites the One Per Cent is its reluctance to pay taxes). When we perceive the natural inequality of the distribution of resources as expressed through Pareto’s “power law”, we are intellectually empowered to try to do something about it.

Those writings on 1920s Italy landed Pareto in trouble, as his theory of the circulation of elites predicted that a “demagogic plutocracy”, dominated by foxes, would necessarily make way for a “military plutocracy”, this time led by lions willing to restore the power of the state. In this, he was often considered a defender of Mussolini, and Il Duce certainly tried to make the best of that possibility by making Pareto a senator. Yet there is a difference between prediction and endorsement, and Pareto, who died in 1923, had already been living as a recluse in Céligny in Switzerland for some time – earning him the nickname “the hermit of Céligny” – with only his cats for company, far removed from day-to-day Italian politics. He remained a liberal to his death, content to stay above the fray.

Like all good liberals, Pareto admired Britain above all. As an economist, he had vehemently defended its system of free trade in the face of outraged opposition in Italy. He also advocated British pluralism and tolerance. Liberalism is important here: in proposing to set up new trade barriers and restrict freedom of movement, exacerbated by their more or less blatant xenophobia, Trump and Brexit challenge the values at the heart of the liberal world.

What was crucial for Pareto was that new elites would rise and challenge the old. It was through the “circulation of elites” that history moved. Yet the fear today is that history has come to a standstill, that elites have ­become fossilised. Electors are fed up with choosing between the same old candidates, who seem to be proposing the same old thing. No wonder people are willing to try something new.

This fear of the immobility of elites has been expressed before. In 1956, the American sociologist C Wright Mills published The Power Elite. The book has not been out of print since. It is thanks to him that the term was anglicised and took on the pejorative sense it has today. For Mills, Cold War America had come to be dominated by a unified political, commercial and military elite. With the 20th century came the growth of nationwide US corporations, replacing the older, more self-sufficient farmers of the 19th century.

This made it increasingly difficult to ­distinguish between the interests of large US companies and those of the nation as a whole. “What’s good for General Motors,” as the phrase went, “is good for America.” As a result, political and commercial interests were becoming ever more intertwined. One had only to add the Cold War to the mix to see how the military would join such a nexus.

Mills theorised what President Dwight D Eisenhower denounced in his January 1961 farewell speech as the “military-industrial complex” (Eisenhower had wanted to add the word “congressional”, but that was thought to be too risky and was struck out of the speech). For Mills, the circulation of elites – a new elite rising to challenge the old – had come to an end. If there was any circulation at all, it was the ease with which this new power elite moved from one part of the elite to the other: the “revolving door”.

The Cold War is over but there is a similar sense of immobility at present concerning the political elite. Must one be the child or wife of a past US president to run for that office? After Hillary Clinton, will Chelsea run, too? Must one have gone to Eton, or at least Oxford or Cambridge, to reach the cabinet? In France is it Sciences Po and Éna?

The vote for Brexit, Trump and the rise of the far right are, beyond doubt, reactions to this sentiment. And they bear out Pareto’s theses: the new elites have aligned themselves with the people to challenge the old elites. The lions are challenging the foxes. Needless to say, the lions, too, are prototypically elites. Trump is a plutocrat. Boris Johnson, the co-leader of the Leave campaign, is as “establishment” as they come (he is an Old Etonian and an Oxford graduate). Nigel Farage is a public-school-educated, multimillionaire ex-stockbroker. Marine Le Pen is the daughter of Jean-Marie Le Pen. Putin is ex-KGB.

Pareto placed his hopes for the continuing circulation of elites in technological, economic and social developments. He believed that these transformations would give rise to new elites that would challenge the old political ruling class.

We are now living through one of the biggest ever technological revolutions, brought about by the internet. Some have argued that social media tipped the vote in favour of Brexit. Arron Banks’s Leave.EU website relentlessly targeted disgruntled blue-collar workers through social media, using simple, sometimes grotesque anti-immigration messages (as a recent profile of Banks in the New Statesman made clear) that mimicked the strategies of the US hard right.

Trump’s most vocal supporters include the conspiracy theorist Alex Jones, who has found the internet a valuable tool for propagating his ideas. In Poland, Jarosław Kaczynski, the leader of the Law and Justice party, claims that the Russian plane crash in 2010 that killed his twin brother (then the country’s president) was a political assassination, and has accused the Polish prime minister of the time, Donald Tusk, now the president of the European Council, of being “at least morally” responsible. (The official explanation is that the poorly trained pilots crashed the plane in heavy fog.)

It need not be like this. Silicon Valley is a world unto itself, but when some of its members – a new technological elite – start to play a more active role in politics, that might become a catalyst for change. In the UK, it has been the legal, financial and technological sectors that so far have led the pushback against a “hard” Brexit. And we should not forget how the social movements that grew out of Occupy have already been changing the nature of politics in many southern European countries.

The pendulum is swinging back to the lions. In some respects, this might be welcome, because globalisation has left too many behind and they need to be helped. However, Pareto’s lesson was one of moderation. Both lions and foxes have their strengths and weaknesses, and political elites are a combination of the two, with one element dominating temporarily. Pareto, as he did in Italy in the 1920s, would have predicted a return of the lions. But as a liberal, he would have cautioned against xenophobia, protectionism and violence.

If the lions can serve as correctives to the excesses of globalisation, their return is salutary. Yet the circulation of elites is a process more often of amalgamation than replacement. The challenge to liberal politics is to articulate a balance between the values of an open, welcoming society and of one that takes care of its most vulnerable members. Now, as ever, the task is to find the balance between the lions and the foxes. l
