Ignorance by Milan Kundera (2002)

This is a really enjoyable book and feels like a return to form for Kundera. I hate to say it because it sounds like such a cliché, but it feels that the reason for this is simply to be that, after three novels set predominantly in France and in a Western consumer capitalist culture which Kundera can’t help but loathe and despise – this one returns to Czechoslovakia, to his homeland – and feels significantly more confident, relaxed, integrated, deep and thoughtful as a result.

It’s a novel about returning from exile. It’s set soon after the collapse of communism in 1989 and the liberation of Czechoslovakia from Russian rule, and describes the journeys back to newly-liberated Czechoslovakia of two émigrés, one man, one woman.

But it is a Kundera novel, so the narrative, such as it is, is routinely interspersed with digressions and thoughts and analyses, primarily about the characters’ perceptions and feelings, then of their personal situations, then of their positions as symbols of ‘the émigré’, then explanations of the broader historical background to their situation, and then, stepping right back from the present, Kundera aligns their ‘returns’ with a) the classical legend of Odysseus, maybe the greatest symbol in European literature of the Returner, and b) with passages about the different words in European languages which attempt to convey the many feelings of the returner, nostalgia, longing for home, and so on.

Ignorance

Thus we discover he is using the word ‘ignorance’ not at all in the common or garden sense of ‘lack of knowledge or information’, but in a subtler sense moderated by placing all around it words from other languages (such as the German Sehnsucht and the Czech stesk) which express ‘nostalgia’, longing, the act of missing something or someone – then by examining its Latin root, to produce a wider deeper definition:

To be unaware of, not know, not experience; to lack or miss. In that etymological light nostalgia seems something like the pain of ignorance, of not knowing. You are far away, and I don’t know what has become of you. My country is far away, and I don’t know what is happening there. (p.6)

Arguably, the rest of the text is an extended mediation on the meaning of this concept, the suffering of the exile, and the bewilderment of return.

Odysseus is doubly relevant: not just as a returner, but a returner after an absence of twenty years, he is surprisingly close to Kundera’s fictional character. It was in 1968 that the Russians invaded Czechoslovakia and suppressed of the Prague Spring, but only in 1969 that they imposed their new government which proceeded to implement its harsh crackdown on all liberals and dissidents. So it was 20 years later that Russian communism collapsed and the Russia-backed Czech communist government fell.

And Odysseus was away from his homeland (Ithaca) for a long 20 years: 10 years fighting at Troy, three wandering across the Mediterranean and having the extraordinary adventures all children learn about; then seven trapped by the magician Calypso, who was also his lover.

Now these disparate elements – geopolitics, personal stories, etymological precision and ancient myth – could easily have hung apart and pulled in different directions. In my opinion his use of these kinds of disparate elements, or different levels, failed to gel in the previous couple of novels.

But here they meld perfectly. All four of these levels or themes naturally complement each other. The feelings and experiences of the present-day émigrés really does illuminate your understanding of how Odysseus must have felt, pitching up in his homeland twenty years after leaving it. And Kundera’s subtle insights into Odysseus’s plight really does help to amplify the bitter experiences of his émigrés in the present day.

To both of them Kundera applies his insights about memory and forgetting, namely the idea developed in Identity that part of the point of friendship it to tell each other stories about the old days and keep memories alive. Exiled to a foreign land, with no friends, those memories atrophy and die. The more intense Odysseus’s longing for his native land – the less he can remember anything about it.

Émigrés gathered together in compatriot colonies keep retelling to the point of nausea the same stories, which thereby become unforgettable. But people who do not spend time with their compatriots, like Irena or Odysseus, are inevitably stricken with amnesia. The stronger their nostalgia, the emptier of recollections it becomes. (p.33, emphasis added)

Plus (as a big history fan) I am fascinated by the light Kundera sheds on the political and social and cultural changes which took place in a communist-dominated society, how it changed so quickly after the fall of communism, and the myriad little insights thrown up as his two protagonists move among this familiar but alien world.

For me, all of these elements come together to make a really fascinating and engaging book.

The characters

Irena

The woman protagonist, Irena, fled Czechoslovakia with her husband Martin, with one little girl and pregnant with another, back in the 1970s. Émigrés from communist countries weren’t all that welcome in the Paris of the 1970s, dominated by its communist party and the fashion for left-wing students. Her husband fell ill and died, and she had a hard time bringing up the girls (cleaning houses, caring for a paraplegic, p.28).

Emigration-dreams

All the émigrés have them, both she and her husband are plagued by them, dreams in which you are wandering the streets of a strange city and the see the uniforms of the Czech police and awake sweating in panic. Dreams like that. Sometimes they came during the day, in the middle of a meeting, a sudden shaft of memory, walking through a green part of Prague, for a moment, becomes more real than the real world. The continual eruption of the unconscious.

Gustaf

Then she met Gustaf, a Swede who’s fled his homeland to get away from his homeland. They become friends then lovers, then partners. He disconcerts her by saying his company are going to open up a small office in Prague. She wants to get away from the old life, not have it hanging over her all the time. Especially her self-centred, garrulous mother. After the fall of communism his company expands this to buying a house in central Prague, with a flat in the eaves where Gustaf stays on his business trips.

Now Irena flies back to Prague and is able to stay there, while she looks up her old friends and has a sort of hen night for women friends only. This scene registers their different reactions, some jealous, some bitter, everyone keen to tell how much they suffered, the ‘suffering contests’ (p.41).

All of this is interesting and moving and subtly described – very unlike the sex comedy shenanigans of the previous novels, Slowness and Identity, which I didn’t like. When references to Odysseus’s experiences as an exile returning after twenty years are interleaved with Irena’s it doesn’t feel contrived or arch; the two complement each other really well.

Josef

In the airport Irena spots a man she knew twenty years earlier. He had been someone else’s boyfriend who she had flirted with at some party downstairs in a bar in Prague. But then she got married and left the country. But she’d always wondered what would have happened. When she introduces herself to him, he is flustered and shy.

Then we cut to his point of view and learn why he is flustered. He is called Josef and he has absolutely no memory of her whatever, can’t even remember her name. He also fled Czechoslovakia, settling in Denmark and marrying. Now his wife is dead and he is making the pilgrimage home.

The great broom

He wriggles free of her and goes on his own quest in Prague, his own odyssey. He goes to the cemetery where his parents are buried and is appalled by how cramped it is, overshadowed by high rise blocks and freeways. He reflects than an invisible broom has swept across the landscape of his childhood, wiping away everything familiar.

And it seems to be getting faster. Things changed slowly ‘back in the day’, now they change before your eyes. This is brought home in the dining room of the hotel where he’s staying and he realises spoken Czech has changed in intonation and tone in the twenty years he’s been away. Now it feels like ‘an unknown language’ (p.55)

Josef’s brother

Then Josef goes on to meet his brother and the sister-in-law who never liked him. I really liked this scene, the way his sense of the feelings of the other two fluctuate, how Kundera captures the changing mood, the sudden embarrassing silences. He realises he must have been seen as The Betrayer, the lucky younger son who ran away. His flight bedevilled his brother’s career as a surgeon, casting a blight over it. Josef had turned his back on a career as a doctor (turning his back on the family tradition pursued by his grandfather and father) in order to become a vet. The motives for his flight are examined.

Josef left in a hurry and mailed his brother the key to his apartment, saying take what he wanted. Now his brother gives him a bundle of notes and journals and diaries and letters. Back at his hotel he goes through them. He realises he has forgotten most of his childhood.

The law of masochistic memory: as segments of their lives melt into oblivion, men slough off whatever they dislike, and feel lighter, freer. (p.76)

He is disconcerted at the combination of ‘sentimentality and sadism’ (p.83) displayed by the diaries of himself as a frustrated virginal teenager.

The teenage girl

Kundera now creates ‘out of the mists of the time when Josef was in high school’ a virginal girl his own age who has just split up with her first boyfriend. She enjoys the fist pangs of ‘nostalgia’, the first teenage tryouts of that feeling of wanting to ‘go back’ (in her case to the happy days when she was going out with X; but you see how this mention of nostalgia ties in with the book’s theme).

She goes out with young Josef. He is petulant and frustrated. When she announces she is going off on a school skiing trip he has a tantrum and dumps her.

Josef tears up his diary and throws the pieces away. But,

The life we’ve left behind us has a bad habit of stepping out of the shadows, of bringing complaints against us, of taking us to court. (p.90)

Gustaf and Irena’s relationship decays

I thought the book was about Irena’s first and major visit back to Prague, but this passage makes it clear that, her partner Gustaf having opened an office in the city, she found herself spending more and more time there, watching as Prague rapidly becomes westernised, repaints itself and fills up with tourists.

Meanwhile her relationship with Gustaf peters out. They stop having sex. They stop even talking because he enjoys talking in American English, talking loud and long, whereas she clings to the French she had learned in Paris, and behind that to the Czech she grew up with, neither of which Gustaf understands. Now, meeting the strange man (Josef) in the airport has revived something in her. He had given her the number of his hotel and when she gets through after trying half a dozen times, she is thrilled and aroused at his voice.

All this contrasts with the gabby loudmouth Gustaf who she can hear downstairs keeping her horrible chatterbox mum in stitches. Josef represents escape from two people she’s come to loathe.

The teenage girl attempts suicide

The narrative cuts back to that teenage girl after her second boyfriend cruelly dumps her. We are intended by now, I think, to realise that the sentimental and sadistic boyfriend was none other than Josef, and I think the distraught girl was a young Irena.

We are told how the teenage girl goes on the school ski trip, one evening walks away from the chalet, as far as she can, swallows a bunch of sleeping pills she’s stolen off her mother, and lies down in the snow to die.

Burying the dead

This narrative breaks off to revive a thought that had been mentioned earlier (and which recurs in Kundera’s later fiction) which is the correct disposal of the dead. When Josef’s wife dies, he fights an almighty battle to stop her family claiming the body and burying it in the family plot. Josef feels she would be abandoned among strangers. (This parallels Chantal’s anxiety in Identity about what happens to the bodies of the dead the instant they’ve gone i.e. they lose all privacy and pored over by pathologists and police and strangers, cut open and humiliated. Which is why she insists on being cremated.)

The suicide survives

She had lain down under a beautiful blue Alpine sky, her head woozily full of images of a beautiful death. She wakes up under a black night sky feeling awful and in fact unable to feel half her body. Evidently she is not dead, and she staggers back to the ski chalet where the doctor diagnoses her with frostbite and says part of her ear will have to be chopped off. Word goes round the other kids and teachers about the girl who tried to kill herself. She is mortified. Now her life divides into two halves – the innocent years under the blue sky of childhood, and the years of knowledge under a black sky.

The implications of human lifespan

There now follow some fascinating passages about the human condition. Nothing impenetrable or difficult, it’s all very accessible. It’s as if he’s made philosophy entertaining. It’s like Heidegger turned into a newspaper editorial.

First idea is a consideration of how much our lifespan – say 80 years – affects meaning. If human beings lived for, say 160 years, then the notion of a Great Return which his book is about, would dissolve into just one of the many peregrinations 180 year-olds would be prone to.

Human memory

Next, Memory. The fact is that human memory retains no more than a millionth, maybe a hundred millionth of our actual lived experiences. If human beings remembered everything they would cease being human and be a different species. One of the things that defines us is the way we forget almost everything.

And why do we remember some things and not others? Because they are part of the complex narratives we tell ourselves about our lives. And these narratives, obviously, vary hugely from person to person.

It’s not just that people remember the same event differently (as Kundera has given us ample examples of throughout his work), but that quite often two people don’t even remember the event at all. Thus Irena powerfully remembers her first meeting with Josef, and remembers him as a symbol or talisman of the single life she left behind when she married her husband soon after. Whereas Josef doesn’t remember her at all.

Kundera evinces both Irena’s experience after he husband died and Josef’s after his wife died: for both of them the shared memories which made up their relationships required constant discussing and sharing. Once the sharing ended, the memories started to decay, worryingly quickly.

Kundera’s discussed some of these issues before but, as I’ve said, they seem to arise more naturally from the subject matter and setting in this book than they do in its immediate predecessors. The result is that it feels more graceful. There are fewer abrupt handbrake turns.

Back to the narrative

Irena goes strolling round Prague, revising the middle class area where she grew up. She walks through woodland to the back of the famous castle. She thinks about her upbringing, the poets and storytellers and the little theatres with their humour – the ‘intangible essence’ of her country.

Josef reflects

He drives out into the country. He reflects on the destiny of the Czechs, a small nation, whose history has been one of fear and domination, yet have refused to bow to their larger neighbours, like the Danes he has settled among.

He and his sister-in-law had bickered about a painting, a painting by a painter friend of his depicting a working class neighbourhood in the flamey colours of the Fauves. Now he realises he doesn’t want it anyway. It would be a splinter of old Prague in his clean, windswept Danish existence. Out of place.

Man cannot know the future because he doesn’t understand the present

This point is made very amusingly though the example of Schoenberg the revolutionary Austrian composer. In the 1920s he announced that his new twelve-tone system would ensure the dominance of German music for a century. Barely ten years later he, a Jew, was forced to flee Nazi Germany, to America. Here he continued to write and developed the fans and acolytes who were to dominate post-war classical music and impose the atonal ‘system’ onto serious music until well into the 1970s.

But where is he now? In Kundera’s view forgotten and ignored (I’m not sure that’s quite true, but his system certainly doesn’t dominate classical music the way it used to).

Anyway, Kundera introduces another level to explain what he means. Imagine two armies meet to determine the fate of the world but unknown to either one carries the plague bacillus which will wipe out the civilisation they’re fighting over.

Same with Schoenberg and his arch-enemy Stravinsky who he spent fifty years slagging off. In the event both were blown away by radio. The advent of radio in the 1920s was the start of the great plague of noise and din and racket which, in Kundera’s view, has ruined music forever. Kundera lets rip with some classic cultural pessimism:

If in the past people would listen to music out of love of music, nowadays it roars everywhere and all the time, ‘regardless of whether we want to hear it’, it roars from loudspeakers, in cars, in restaurants, in elevators, in the streets, in waiting rooms, in gyms, in the earpieces of Walkmans, music rewritten, reorchestrated, abridged, and stretched out, fragments of rock, of jazz, of opera, a flood of everything jumbled together so that we don’t know who composed it (music become noise is anonymous), so that we can’t tell beginning from end (music become noise has no form); sewage-water music in which music is dying. (p.146)

So who cares any more whether Schoenberg or Stravinsky was right. Both have gone down under a tsunami of sewage-water music.

Irena and music

As so often in Kundera, having shared a thought or idea with us for a couple of pages, he then applies it to one of his walking experiments, also known as ‘characters. Thus we eavesdrop on how much Irena hates the way music blares from every outlet, how much she wants to get away from it to a realm of quiet. On one side of her the bedside radio which, even in its speech programmes, contains snippets of sewage music; on the other side Gustaf snoring like a pig. (This trip to Prague has crystallised how much she hates him.)

She is tense because it is the day when she’s made an appointment to meet Josef.

Josef and N

Before he left the country, Josef had been helped by N., a devout communist who stood up for people like him. Josef goes to meet him, his head full of questions about how he felt about collaborating in the oppression of his people, how things changed towards the end, what he feels now. But N.’s house is packed full of his grown-up kids milling around and he and Josef can’t manage to get a conversation started. He laments the capitalist commercialisation he sees all over the country. N. nods his head. ‘National independence has been an illusion for some time, now.’

Josef abandons his plans to engage in Weighty Conversation and, as soon as he does so, experiences a sudden release and sense of liberation. Suddenly he and N. are like two old friends chatting and gossiping about the past. (There is a certain polemical purpose in the notion that Josef the émigré has more in common with a former communist than with his own brother. His brother represents bitterness, and his wife, Josef’s sister-in-law, would string up the old communists if she could. Josef’s relaxed and warm conversation with his old friend shows how irrelevant that witch-hunting mentality is to the situation. Celebrate what we have in the here and now. Not least because ‘they’ – N. nods towards his adult children – have no idea what they’re talking about.)

The memory theme reappears because N. thanks Josef for acting as his alibi to his wife, on an occasion when N. was off with his mistress. Josef has absolutely no memory of this happening and doubts it was him, but acquiesces in the story. Earlier, his brother had reminded him of some boyhood lines he had supposedly uttered, and his sister-in-law reminded him that he used to scandalise the family with his anti-clerical sentiments. Josef remembers none of this, none of it.

Irena and Josef

They meet at his hotel. They chat and get on. She describes how alien she feels in Prague and yet how she has been cold-shouldered in Paris. The French accepted her and Martin as Heroic Exiles. When the wall came down and she could go back, she realised her few friends slowly lost contact with her because she was no longer interesting.

The suicide girl grown into a woman

I was wrong about the suicide teenager being Irena. It’s her best friend from the old days, Milada, who alone of the cackling women at the hen night reception for Irena, makes the effort to talk to her and understand her. At the time Kundera had told us that she had a very particular hairstyle, the hair cut to perfectly frame her face. Now we realise it is to hide the ear she had cut off because of the frostbite. For her, while Josef and Irena get to know each other in the Prague hotel bar, it is another boring day driving out to a suburb, having a beer and a sandwich alone in a bar.

Except that she has learned that he has come back, the teenage boy who rejected her and prompted her suicide attempt and the loss of her ear. Him. Josef.

Irena and Josef

It’s so noisy with sewage-water music in the bar that Josef invites Irena up to his bedroom. He’s reading the Odyssey. They explicitly compare Odysseus’s 20 year exile with Irena’s own. Talk swiftly moves to Odysseus and Penelope’s first night back in bed. Irena describes it then, half drunk, describes it again using coarse sex words. Both are immediately aroused and tumble into bed. Yes. It is a Milan Kundera novel where, no matter how artful, erudite and thought-provoking the ideas and discussion, straightforward heterosexual penetrative sex is never far away.

It was the sound of those rude words in their native Czech. Both have been married to or living with people who don’t speak Czech. The sound of those words in their native tongue, certainly stimulates Irena to ecstasies of sexual abandonment, she wants to do everything, try every position, and then describe out loud her crudest fantasies, voyeurism, exhibitionism (to be honest, in the era of Fifty Shades of Grey, these do not sound like the wildest fantasies).

Gustaf and Irena’s mother

She is a loud bossy vulgar woman who Irena has been trying to escape all her life. She lives in one of the rooms of the big house Gustaf’s company bought after the liberation. He gets back after a heavy lunch with clients. She has put on some dance music and playfully dances round the room. She takes his hand and makes her dance with her. She pulls him over towards the wall-length mirror. She places her hand on his crotch. They continue dancing. She lets her robe fall open so he can see her breasts and pubic triangle. They continue dancing. She slips her hand down his trousers to touch his hardening member.

Irena and Josef

Irena is exhausted and drunk. She bursts into tears. One thing leads to another and suddenly she realises the awful truth – he doesn’t know who she is. He didn’t on the plane, or in their follow-up phone calls, or downstairs in the bar, or now. She stands and demands he tell her her name. He is silent. Oh dear.

Gustaf and Irena’s mother

Gustaf withdraws from Irena’s mother’s quavery wobbly body. In the darkness she intones that he is quite free to make love to her whenever he likes, but under no obligation. Now, throughout the book we’ve been gently reminded that Gustaf is a bit of a mother’s boy, who fled the responsibility of his wife and child. Now, we realise, he has finally arrived home. Irena’s mother offer him precisely the reassurance and mother love he’s always sought. He reaches out to stroke her cellulite-wobbly buttocks.

Irena and Josef

Abruptly drunk tearful Irena collapses on the bed and passes out. She starts snoring. Josef knees beside her naked body and wonders: could he spend his life with her? she is so obviously in love with him? is she the sister-lover he’s been seeking (on and off) throughout the book?

The suicide girl

Alone and sad, she is in her flat, she is a vegetarian because she is terrified by the thought of eating bodies, that we are all bodies, that she is a body. She has a sad snack dinner and looks at herself in the mirror. She lifts up her hair and looks at her damaged ear. She became a scientist and dreams about flying off into space to find a world where people don’t have bodies.

I thought she and Josef would have had some dramatic reunion in which she blamed him for ruining her life (after he, the selfish teenager, dumped her, she made her suicide attempt, then had part of her ear cut off due to frostbite and gangrene, then she was too scared to show herself to men and never married). But it doesn’t happen, and it feels like an opportunity (deliberately) missed. Remember when he wrote:

The life we’ve left behind us has a bad habit of stepping out of the shadows, of bringing complaints against us, of taking us to court. (p.90)

I thought this was a strong hint that the jilted girlfriend was going to step out of the shadows to confront Josef. Shame. It feels a little like coitus interruptus, a little like the flirting with the reader Kundera does in all his books, promising big things which, somehow, don’t quite come off.

Josef leaves

He writes sleeping snoring Irena a brief sincere note, telling her she has the hotel room till noon the next day. Then packs his bags, goes downstairs, tells reception there’s a guest sleeping in the room who’s not to be disturbed, takes a taxi to the airport and catches his flight. The plane flies up through the clouds and into the big empty black empyrean of night dotted with stars.

Irrationality: The Enemy Within by Stuart Sutherland (1992)

The only way to substantiate a belief is to try to disprove it. (p.48)

Sutherland was 65 when he wrote this book, nearing the end of a prestigious career in psychology research. His aim was to lay out, in 23 themed chapters, all the psychological and sociological research data  from hundreds of experiments, which show just how prey the human mind is to a plethora of unconscious biases, prejudices, errors, mistakes, misinterpretations and so on – the whole panoply of ways in which the supposedly rational human beings can end up making grotesque mistakes. By the end he claims to have defined and demonstrated over 100 distinct cognitive errors humans are prone to (p.309).

I first read it in 2000 and it made a big impact on me because I didn’t really know that this entire area of study existed, and had certainly never read such a compendium of sociology and psychology experiments before.

I found the naming of the various errors particularly powerful. They reminded me of the lists of weird and wonderful Christian heresies I was familiar with from years of reading medieval history. And, after all, the two have a lot in common, both being lists of ‘errors’ which the human mind can make as it falls short of a) orthodox theology and b) optimally rational thinking, the great shibboleths of the Middle Ages and of the Modern World, respectively.

 

Reading it now, 20 years later, having brought up a couple of children and worked for a while in big government departments, I am a lot less shocked and amazed. I have witnessed at first hand the utter irrationality of small and medium-sized children – and then so many examples of the corporate conformity, avoidance of embarrassment, unwillingness to speak up, deferral to authority, and general mismanagement to be found in the civil service that, upon rereading the book, hardly any of it came as a surprise, more a confirmation of what I’ve witnessed at first hand.

But to have the errors so carefully named and defined and worked through in a structured way, with so many experiments giving such vivid proof of how useless humans are at even basic logic was still very enjoyable.

What is rationality?

You can’t define irrationality without first defining what you mean by rationality:

Rational thinking is most likely to lead to the conclusion that is correct, given the information available at the time (with the obvious rider that, as new information comes to light, you should be prepared to change your mind).

Rational action is that which is most likely to achieve your goals. But in order to achieve this, you have to have clearly defined goals. Not only that but, since most people have multiple goals, you must clearly prioritise your goals.

Few people think hard about their goals and even fewer think hard about the many possible consequences of their actions. (p.129)

Cognitive biases contrasted with logical fallacies

Before proceeding it’s important to point out that there is a wholly separate subject of logical fallacies. As part of his Philosophy A-Level my son was given a useful handout with a list of about fifty of these. But logical fallacies are not the same as cognitive biases.

A logical fallacy stems from an error in a logical argument; it is specific and easy to identify and correct. Cognitive bias derives from deep-rooted, thought-processing errors which themselves stem from problems with memory, attention, self-awareness, mental strategy and other mental mistakes. Far harder to acknowledge, in many cases, very hard to correct.

Fundamentals of irrationality

1. Innumeracy One of the largest causes of all irrational behaviour is that people by and large don’t understand statistics or maths. Thus most people are not intellectually equipped to understand the most reliable type of information available to human beings – data in the form of numbers. Instead they tend to make decisions based on a wide range of faulty and irrational psychological biases.

2. Physiology People are often influenced by physiological factors. Apart from obvious ones like tiredness or hunger, which are universally known to affect people’s cognitive abilities, there are also a) drives (direct and primal) like hunger, thirst, sex, and b) emotions (powerful but sometimes controllable) like love, jealousy, fear and – especially relevant – embarrassment: acute reluctance to acknowledge limits to your own knowledge or that you’ve made a mistake.

More seriously people can be alcoholics, drug addicts, and prey to a wide range of other obsessive behaviours, not to mention suffering from a wide range of mental illnesses or conditions which undermine any attempt at rational decision-making, such as stress, anxiety or, at the other end of the spectrum, depression and loss of interest.

3. The functional limits of consciousness Numerous experiments have shown that human beings have a limited capacity to process information. Given that people rarely have a) a sufficient understanding of the relevant statistical data, and b) the RAM capacity to process all the data required to make the optimum decision, it is no surprise that most of us fall back on all manner of more limited, non-statistical biases and prejudices when it comes to making decisions.

The wish to feel good The world is threatening, dangerous and competitive. Humans want to feel safe, secure, calm, in control. This is fair enough, but it does mean that people have a way of blocking out any kind of information which threatens them. People irrationally believe they are cleverer than they in fact are, are qualified in areas of activity of knowledge where they aren’t, people stick to bad decisions for fear of being embarrassed or humiliated, and for the same reason reject new evidence which contradicts their position.

Named types of error and bias

Jumping to conclusions Sutherland tricks the reader no page one by asking a series of questions and then pointing out, that if you tried to answer about half of them, you are a fool since they don’t contain enough information to arrive at any sort of solution. Jumping to conclusions before we have enough evidence is a basic and universal error. One way round this is to habitually use a pen and paper to set out the pros and cons of any decision, which also helps highlight areas where you realise you don’t have enough information.

The availability error All the evidence is that the conscious mind can only hold a small number of data or impressions at any one time (near the end of the book, Sutherland claims the maximum is seven items, p.319). Many errors are due to people reaching for the most available explanation, using the first thing that comes to mind, and not taking the time to investigate further and make a proper, rational survey of the information.

Many experiments show that you can unconsciously bias people by planting ideas, words or images in their minds which then directly affect decisions they take hours later about supposedly unconnected issues.

Studies show that doctors who have seen a run of a certain condition among their patients become more likely to diagnose it in patients who don’t have it. The diagnosis is more ‘available’.

The news media is hard-wired to publicise shocking and startling stories which leads to the permanent misleading of the reading public. One tourist eaten by a shark in Australia eclipses the fact that you are far more likely to die in a car crash than be eaten by a shark.

Thus ‘availability’ is also affected by impact or prominence. Experimenters read out a list of men and women to two groups without telling them that there are exactly 25 men and 25 women, and asked them to guess the ratio of the sexes. If the list included some famous men, the group was influenced to think there were more men, if the list included famous women, the group thought there are more women than men.

The entire advertising industry is based on the availability error in the way it invents straplines, catchphrases and jingles designed to pop to the front of your mind when you consider any type of product, to be – in other words – super available.

I liked the attribution of the well-known fact that retailers price goods at just under the nearest pound, to the availability error. Most of us find £5.95 much more attractive than £6. It’s because we only process the initial 5, the first digit, it is more available.

Numerous studies have shown that the effect is hugely increased under stress. Under stressful situations – in an accident – people fixate on the first solution that comes to mind and refuse to budge.

The primacy effect First impressions. Interviewers make up their minds in the first minute of an interview and then spend the rest of the time collecting data to confirm that first impression.

The anchor effect In picking a number people tend to choose one close to any number they were presented with. Two groups were asked to estimate whether the population of Turkey was a) bigger than 5 million b) less than 65 million, and what it was. The group who’d had 5 million planted in their mind hovered around 15 million, the group who’d had 65 million hovered around 35 million. They were both wrong. It is 80 million.

The halo effect People extrapolate the nature of the whole from just one quality e.g. in tests, people think attractive people must be above average in personality and intelligence although of course there is no reason why they should be. Hence this error’s alternative name, the ‘physical attractiveness stereotype’. The halo effect is fundamental to advertising which seeks to associate images of beautiful men, women, smiling children, sunlit countryside etc with the product.

The existence of the halo effect and primacy effect are both reasons why interviews are a poor way to assess candidates for jobs or places.

The devil effect Opposite of the above: extrapolating from negative appearances to the whole. This is why it’s important to dress smartly for an interview or court appearance, it really does influence. In an experiment examiners were given identical answers, but some in terrible handwriting, some in beautifully clear handwriting. Clear handwriting consistently scored higher marks despite identical factual content of the scripts.

Illusory correlation People find links between disparate phenomena which simply don’t exist, thus:

  • people exaggerate the qualities of people or things which stand out from their environments
  • people associate rare qualities with rare things

This explains a good deal of racial prejudice: a) immigrants stand out b) a handful of immigrants commit egregious behaviour – therefore it is a classic example of illusory correlation to associate the two. What is missing is taking into account all the negative examples i.e. the millions of immigrants who make no egregious behaviour and whose inclusion would give you a more accurate statistical picture. Pay attention to negative cases.

Stereotypes 1. People tend to notice anything which supports their existing opinions. 2. We notice the actions of ‘minorities’ much more than the actions of the invisible majority.

Projection People project onto neutral phenomena patterns and meanings they are familiar with or which bolster their beliefs. Compounded by –

Obstinacy Sticking to personal opinions (often made in haste / first impressions / despite all evidence to the contrary) aka The boomerang effect When someone’s opinions are challenged, they just become more obstinate about it. Aka Belief persistence. Aka pig-headedness. Exacerbated by –

Group think People associate with others like themselves, which makes them feel safe by a) confirming their beliefs and b) letting them hide in a crowd. Experiments have shown how people in self-supporting groups are liable to become more extreme in their views. Also – and I’ve seen this myself – groups will take decisions that almost everyone in the group, as individuals, know to be wrong – but no-one is prepared to risk the embarrassment or humiliation of pointing it out. The Emperor’s New Clothes. Groups are more likely to make irrational decisions than individuals are.

Confirmation bias The tendency to search for, interpret, favour, and recall information in a way that confirms one’s pre-existing beliefs or hypotheses. In an experiment people were read out a series of statements about a named person, who had a stated profession and then two adjectives describing them, one what you’d expect, the other less predictable. ‘Carol, a librarian, is attractive and serious’. When asked to do a quiz at the end of the session, participants showed a marked tendency to remember the expected adjective, and forget the unexpected one. Everyone remembered that the air stewardess was ‘attractive’ but remembered the librarian for being ‘serious’.

We remember what we expect to hear. (p.76)

Or: we remember what we remember in line with pre-existing habits of thought, values etc.

We marry people who share our opinions, we have friends with people who share our opinions, we agree with everyone in our circle on Facebook.

Self-serving biases When things go well, people take the credit, when things go badly, people blame external circumstances.

Avoiding embarrassment People obey, especially in a group situation, bad orders because they don’t want to stick out. People go along with bad decisions because they don’t want to stick out. People don’t want to admit they’ve made a mistake, in front of others, or even to themselves.

Avoiding humiliation People are reluctant to admit mistakes in front of others. And rather than make a mistake in front of others, people would rather keep quiet and say nothing (in a meeting situation) or do nothing, if everyone else is doing nothing (in an action situation). Both of these avoidances feed into –

Obedience The Milgram experiment proved that people will do any kind of atrocity for an authoritative man in a white coat. All of his students agreed to inflict life-threatening levels of electric shock on the victim, supposedly wired up in the next door room and emitting blood curdling (faked) screams of pain. 72% of Senior House Officers wouldn’t question the decision of a consultant, even if they thought he was wrong.

Conformity Everyone else is saying or doing it, so you say or do it so as not to stick out / risk ridicule.

Obedience is behaving in a way ordered by an authority figure. Conformity is behaving in a way dictated by your peers.

The wrong length lines experiment. You’re put in a room with half a dozen stooges, and shown a piece of card with a line on it and then another piece of card with three lines of different length on it, and asked which of the lines on card B is the same length as the line on card A. To your amazement, everyone else in the room chooses a line which is obviously wildly wrong. In experiments up to 75%! of people in this situation go along with the crowd and choose the line which they are sure, can see, know is wrong – because people are that easily swayed.

Sunk costs fallacy The belief that you have to continue wasting time and money on a project because you’ve invested x amount of time and money to date. Or ‘throwing good money after bad’.

Sutherland keeps cycling round the same nexus of issues, which is that people jump to conclusions – based on availability, stereotypes, the halo and anchor effects – and then refuse to change their minds, twisting existing evidence to suit them, ignoring contradictory evidence.

Misplaced consistency & distorting the evidence Nobody likes to admit (especially to themselves) that they are wrong. Nobody likes to admit (especially to themselves) that they are useless at taking decisions.

Our inability to acknowledge our own errors even to ourselves is one of the most fundamental causes of irrationality. (p.100)

And so:

  • people consistently avoid exposing themselves to evidence that might disprove their beliefs
  • on being faced with evidence that disproves their beliefs, they ignore it
  • or they twist new evidence so as to confirm their existing beliefs
  • people selectively remember their own experiences, or misremember the evidence they were using at the time, in order to validate their current decisions and beliefs
  • people will go to great lengths to protect their self-esteem

Sutherland says the best cleanser / solution / strategy to fixed and obstinate ideas is to make the time to gather as much evidence as possible and to try to disprove your own position. The best solution will be the one you have tried to demolish with all the evidence you have and still remains standing.

People tend to seek confirmation of their current hypothesis, whereas they should be trying to disconfirm it. (p.138)

Fundamental attribution error Ascribing other people’s behaviour to their character or disposition rather than to their situation. Subjects in an experiment watched two people holding an informal quiz: the first person made up questions (based on what he knew) and asked the second person who, naturally enough, hardly got any of them right. Observers consistently credited the quizzer with higher intelligence than the answerer, completely ignoring the in-built bias of the situation, and instead ascribing the difference to character.

We are quick to personalise and blame in a bid to turn others into monolithic entities which we can then define and control – this saves time and effort, and makes us feel safer and secure – whereas the evidence is that all people are capable of a wide range of behaviours depending on the context and situation.

Once you’ve pigeon-holed someone, you will tend to notice aspects of their behaviour which confirm your view – confirmation bias and/or illusory correlation and a version of the halo/devil effect. One attribute colours your view of a more complex whole.

Actor -Observer Bias Variation on the above: when we screw up we find all kinds of reasons in the situation to exonerate ourselves, we performed badly because we’re ill, jet-lagged, grandma died, reasons that are external to us. If someone else screws up, it is because they just are thick, lazy, useless. I.e. we think of ourselves as complex entities subject to multiple influences, and others as monolithic types.

False Consensus Effect Over-confidence that other people think and feel like us, that our beliefs and values are the norm – in my view one of the greatest errors of our time.

It is a variation of the ever-present Availability Error because when we stop to think about any value or belief we will tend to conjure up images of our family and friends, maybe workmates, the guys we went to college with, and so on: in other words, the people available to memory – simply ignoring the fact that these people are a drop in the ocean of the 65 million people in the UK. See Facebubble.

The False Consensus Effect reassures us that we are normal, our values are the values, we’re the normal ones: it’s everyone else who is wrong, deluded, racist, sexist, whatever we don’t approve of.

Not in Sutherland’s book, I’ve discovered some commentators naming this the Liberal fallacy:

For liberals, the correctness of their opinions – on universal health care, on Sarah Palin, on gay marriage – is self-evident. Anyone who has tried to argue the merits of such issues with liberals will surely recognize this attitude. Liberals are pleased with themselves for thinking the way they do. In their view, the way they think is the way all right-thinking people should think. Thus, “the liberal fallacy”: Liberals imagine that everyone should share their opinions, and if others do not, there is something wrong with them. On matters of books and movies, they may give an inch, but if people have contrary opinions on political and social matters, it follows that the fault is with the others. (Commentary magazine)

Self-Serving Bias People tend to give themselves credit for successes but lay the blame for failures on outside causes. If the project is a success, it was all due to my hard work and leadership. If it’s a failure, it’s due to circumstances beyond my control, other people not pulling their weight etc.

Preserving one’s self-esteem These three errors are all aspects of preserving our self-esteem. You can see why this has an important evolutionary and psychological purpose. In order to live, we must believe in ourselves, our purposes and capacities, believe our values are normal and correct, believe we make a difference, that our efforts bring results. No doubt it is a necessary belief and a collapse of confidence and self-belief can lead to depression and possibly despair. But that doesn’t make it true. People should learn the difference between having self-belief to motivate themselves, and developing the techniques to gather the full range of evidence – including the evidence against your own opinions and beliefs – which will enable them to make correct decisions.

Representative error People estimate the likelihood of an event by comparing it to an existing prototype / stereotype that already exists in our minds. Our prototype is what we think is the most relevant or typical example of a particular event or object. This often happens around notions of randomness: people have a notion of what randomness should look like i.e. utterly scrambled. But in fact plenty of random events or sequences arrange themselves into patterns we find meaningful. So we dismiss them as not really random.  I.e. we have judged them against our preconception of what random ought to look like.

Ask a selection of people which of these three sets of six coin tosses where H stands for heads, T for tails is random.

  1. TTTTTT
  2. TTTHHH
  3. THHTTH

Most people will choose 3 because it feels random. But of course all three are equally likely or unlikely.

Hindsight In numerous experiments people have been asked to predict the outcome of an event, then after the event questioned about their predictions. Most people forget their inaccurate predictions and misremember that they were accurate.

Overconfidence Most professionals have been shown to overvalue their expertise i.e. exaggerate their success rates.


Statistics

The trouble with this and Paulos’s books is that the entire area of statistics is separate and distinct from errors of thought and cognitive biases. I.e. you can imagine someone who avoids all of the cognitive and psychological errors named above, but still makes howlers when it comes to statistics simply because they’re not very good at it.

This is because the twin areas of Probability and Statistics are absolutely fraught with difficulty. Either you have been taught the correct techniques, and understand them, and practice them regularly (and both books demonstrate that even experts make howling mistakes in the handling of statistics and probability) or, like most of us, you have not.

As Sutherland points out, most people’s knowledge of statistics is non-existent. Since we live in a society whose public discourse i.e. politics, is ever more dominated by statistics, there is a simple conclusion: most of us have little or no understanding of the principles and values which underpin modern society.

Errors in estimating probability or misunderstanding samples, opinion polls and so on are probably a big part of irrationality, but I felt that they’re so distinct from the psychological biases discussed above, that they almost require a separate volume, or a separate ‘part’ of this volume. Briefly, common mistakes are:

  • too small a sample size
  • biased sample
  • not understanding that any combination of probabilities is less likely than either on their own, which requires an understanding of base rate or a priori probability
  • the law of large numbers – the more a probabilistic event takes place, the more likely the result will move towards the theoretical probability
  • be aware of the law of regression to the mean
  • be aware of the law of large numbers

Gambling

This is even more true of gambling. It is a highly specialised and advanced form of probability applied to games which have been pored over by very clever people for centuries. It’s not a question of a few general principles, this is a vast, book-length subject in its own right. Some points that emerge:

  • always work out the expected value of a bet i.e. the amount to be won times the probability of winning it

The two-by-two box

It’s taken me some time to understand this principle which is given in both Paulos and Sutherland.

When two elements with a yes/no result are combined, people tend to look at the most striking correlation and fixate on it. The only way to avoid the false conclusions that follow from that is to draw a 2 x 2 box and work through the figures.

Here is a table of 1,000 women who had a mammogram because their doctors thought they had symptoms of breast cancer.

Women with cancer Women with no cancer Total
Women with positive mammography 74 110 184
Women with negative mammography 6 810 816
80 920 1000

Bearing in mind that a conditional probability is saying that if X and Y are linked, then the chances of X, if Y, are so and so – i.e. the probability of X is conditional on the probability of Y – this table allows us to work out the following conditional probabilities:

1. The probability of getting a positive mammogram or test result, if you do actually have cancer, is 74 out of 80 = .92 (out of the 80 women with cancer, 74 were picked up by the test)

2. The probability of getting a negative mammogram or test result and not having cancer, is 810 out of 920 = .88

3. The probability of having cancer if you test positive, is 74 out of 184 = .40

4. The probability of having cancer if you test negative, is 6 out of 816 = .01

So 92% of women of women with cancer were picked up by the test. BUT Sutherland quotes a study which showed that a shocking 95% of doctors thought that this figure – 92% – was also the probability of a patient who tested positive having the disease. By far the majority of US doctors thought that, if you tested positive, you had a 92% chance of having cancer. They fixated on the 92% figure and transposed it from one outcome to the other, confusing the two. But this is wrong. The probability of a woman testing positive actually having cancer is given in conclusion 3 – 74 out of 184 = 40%. This is because 110 out of the total 184 women tested positive, but did not have cancer.

So if a woman tested positive for breast cancer, the chances of her actually having it are 40%, not 92%. Quite a big difference (and quite an indictment of the test, by the way). And yet 95% of doctors thought that if a woman tested positive she had a 92% likelihood of having cancer.

Sutherland goes on to quote a long list of other situations where doctors and others have comprehensively  misinterpreted the results of studies like this, with varied and sometimes very negative consequences.

The moral of the story is if you want to determine whether one event is associated with another, never attempt to keep the co-occurrence of events in your head. It’s just too complicated. Maintain a written tally of the four possible outcomes and refer to these.


Deep causes

Sutherland concludes the book by speculating that all the hundred or so types of irrationality he has documented can be attributed to five fundamental causes:

  1. Evolution We evolved to make snap decisions, we are brilliant at processing visual information and responding before we’re even aware of it. Conscious thought is slower, and the conscious application of statistics, probability, regression analysis and so on is very slow and laborious. Most people never acquire it.
  2. Brain structure As soon as we start perceiving, learning and remembering the world around us brain cells make connections. The more the experience is repeated, the stronger the connections become. Routines and ruts form, which are hard to budge.
  3. Heuristics Everyone develops mental short-cuts, techniques to help make quick decisions. Not many people bother with the laborious statistical techniques for assessing relative benefits which Sutherland describes.
  4. Failure to use elementary probability and elementary statistics Ignorance is another way of describing this, mass ignorance. Sutherland (being an academic) blames the education system. I, being a pessimist, attribute it to basic human nature. Lots of people just are lazy, lots of people just are stupid, lots of people just are incurious.
  5. Self-serving bias In countless ways people are self-centred, overvalue their judgement and intelligence, overvalue the beliefs of their in-group, refuse to accept it when they’re wrong, refuse to make a fool of themselves in front of others by confessing error or pointing out errors in others (especially the boss) and so on.

I would add two more:

Suggestibility. Humans are just tremendously suggestible.

Say a bunch of positive words to test subjects, then ask them questions on an unrelated topic: they’ll answer positively. Take a different representative sample of subjects and run a bunch of negative words past them, then ask them the same unrelated questions, and their answers will be measurably more negative.

Ask subjects how they get a party started and they will talk and behave in an extrovert manner to the questioner. Ask them how they cope with feeling shy and ill at ease at parties, and they will tend to act shy and speak quieter. Thus, the initial terms or anchor defines the ensuing conversation.

In one experiment a set of subjects were shown one photo of a car crash. Half were asked to describe what they think happened when one car hit another; the other half were asked to describe what they thought happened when one car smashed into the other. The ones given the word ‘smashed’ gave much more melodramatic accounts. Followed up a week later, the subjects were asked to describe what they remembered of the photo. The subjects given the word ‘hit’ fairly accurately described it, whereas the subjects given the word ‘smashed’ invented all kinds of details like a sea of broken glass around the vehicles which simply wasn’t there, which their imaginations had invented, all at the prompting of one word.

Many of the experiments Sutherland quotes demonstrate what you might call higher-level biases: but underling many of them is this simple-or-garden observation, that people are tremendously easily swayed, by both external and internal causes, away from the line of cold logic.

Anthropomorphism Another big underlying cause is anthropomorphism, namely the attribution of human characteristics to objects, events, chances, odds and so on. In other words, people really struggle to accept the high incidence of random accidents. Almost everyone attributes a purpose or intention to almost everything that happens. This means our perceptions of almost everything in life are skewed from the start.

During the war Londoners devised innumerable theories about the pattern of German bombing. After the war, when Luftwaffe records were analysed, it showed the bombing was more or less at random.

The human desire to make sense of things – to see patterns where none exists or to concoct theories… can lead people badly astray. (p.267)

Suspending judgement is about the last thing people are capable of. People are extremely uneasy if things are left unexplained. Most people rush to judgement like water into a sinking ship.

Cures

  • keep an open mind
  • reach a conclusion only after reviewing all the possible evidence
  • it is a sign of strength to change one’s mind
  • seek out evidence which disproves your beliefs
  • do not ignore or distort evidence which disproves your beliefs
  • never make decisions in a hurry or under stress
  • where the evidence points to no obvious decision, don’t take one
  • learn basic statistics and probability
  • substitute mathematical methods (cost-benefit analysis, regression analysis, utility theory) for intuition and subjective judgement

Comments on the book

Out of date

Irrationality was first published in 1992 and this makes the book dated in several ways (maybe this is why the first paperback edition was published by upmarket mass publisher Penguin, whereas the most recent edition was published by the considerably more niche publisher, Pinter & Martin).

In the chapter about irrational business behaviour he quotes quite a few examples from the 1970s and the oil crisis of 1974. These and other examples – such as the long passage about how inefficient the civil service was in the early 1970s – feel incredibly dated now.

And the whole thing was conceived, researched and written before there was an internet or any of the digital technology we take for granted nowadays. Can’t help make wonder how the digital age has changed or added to the long list of biases, prejudices and faulty thinking he gives, and what errors of reason have emerged specific to our fabulous digital technology.

Grumpy

But it also has passages where Sutherland extrapolates out to draw general conclusions and some of these sound more like the grumblings of a grumpy old man than anything based on evidence.

Thus Sutherland whole-heartedly disapproves of ‘American’ health fads, dismisses health foods as masochistic fashion and is particularly scathing about jogging. He thinks ‘fashion’ in any sphere of life is ludicrously irrational. He is dismissive of doctors who he accuses of rejecting statistical evidence, refusing to share information with patients and wildly over-estimating their own diagnostic abilities.

He thinks the publishers of learned scientific journals are more interested in making money out of scientists than in ‘forwarding the progress of science’ (p.185). He thinks the higher average pay that university graduates tend to get is unrelated to their attendance at university and more to do with having well connected middle and upper middle class parents, and thus considers the efforts of successive Education Secretaries to introduce student loans to be unscientific and innumerate (p.186). He criticises Which consumer magazine for using too small samples in its testing (p.215). In an extended passage he summarises Leslie Chapman’s blistering (and very out of date) critique of the civil service, Your Disobedient Servant published in 1978 (pp.69-75).

He really has it in for psychoanalysis which he accuses of all sorts of irrational thinking such as projecting, false association, refusal to investigate negative instances, failing to take into account the likelihood that the patient would have improved anyway, and so on. Half way through the book he gives a thumbnail summary:

Self-deceit exists on a massive scale: Freud was right about that. Where he went wrong was in attributing it all to the libido, the underlying sex drive. (p.197)

In other words, the book is liberally sprinkled with Sutherland’s own personal opinions, which sometimes risk giving it a crankish feel.

On the other hand it’s surprising to see how some hot button issues haven’t changed at all. In the passage about the Prisoners’ Dilemma, Sutherland takes as a real life example the problem the nations of the world were having in 1992 in agreeing to cut back carbon dioxide emissions. Sound familiar?

He also states that the single biggest factor undermining international co-operation was America’s refusal to sign global treaties to limit global warming. In 1992! Plus ça change.

Against stupidity the gods themselves contend in vain

And finally, these are the mistakes made by the most intelligent and best educated among us, people trained to assess and act on evidence.

Neither this nor John Allen Paulos’s books take into account the obvious fact that lots of people are, how shall we put it, of low educational achievement. They begin with poor genetic material, are raised in families where no-one cares about education, are let down by poor schools, and are excluded or otherwise demotivated, with the result that :

  • the average reading age in the UK is 9
  • about one in five Britons (over ten million) are functionally illiterate, and probably about the same rate innumerate

which all contributes to the general festival of irrationality.
