BBC Column: auction psychology

My BBC Future column from last week. The original is here

The reason we end up overspending is a result of one unavoidably irrational part of the bidding process – and that’s ourselves.

The allure and tension of an auction are familiar to most of us – let’s face it, we all like the idea of picking up a bargain. And on-line auction sites like eBay cater for this, allowing us to share in the over-excitement of auction bidding in the privacy of our homes. Yet somehow, despite our better judgement, we end up paying more than we know we should have done on that piece of furniture, equipment or clothing. What’s going on?

One estimate states that about half of eBay auctions result in higher sale prices than the “buy it now” price. This is a paradox. If the people going into the auction really wanted the item so badly, why didn’t they get it for less by paying the “buy it now” price?

This has nothing to do with the way the eBay bidding system works. In fact, unlike most auctions, the eBay auction process is actually perfectly designed to allow rational outcomes. By allowing you to set a private “maximum bid” in advance, eBay auctions are better for individual buyers than public auctions where everyone has to shout out their bid in public. No, the reason auctions – both on and offline – produce higher sale prices than any bidder originally imagined they would pay is because of one irreducibly irrational part of the bidding process: the bidders themselves.

Auctions push a number of our psychological buttons, and in fact the phenomenon of “auction fever” is well documented. They are social occasions, with lots of other people around, and this tends to increase your physiological arousal, an effect called social facilitation. As your adrenaline pumps, your heart beats faster, and your reactions quicken. This is ideal for something like sports, but makes cool rational decision making harder. The very rich often send delegates to auctions, and as well as avoiding the paparazzi I suspect this is also a strategy to combat the over-excitement induced by being physically present in the situation.

On top of this, auctions are time pressured, and – by definition – you’re bidding on something you value highly. These factors create excitement whether you are in the room or not.

Persuasive powers

Another psychological bias that operates in auctions is the endowment effect, where we tend to over-value things we already possess. By encouraging us to connect the bid (our money) with the sale item, bidding on items lets us fantasise about owning them – stimulating a kind of endowment effect. This is why the auction catalogue (or the item picture and description on a website) is so important. This forms part of the psychological journey the seller wants you to go on to imagine owning this item in advance, so you’ll place a higher value on it, and so pay more to make imagination reality.

Persuasion plays a huge part here, and the best book you can read on the psychology of the subject is Robert Cialdini’s Influence. Cialdini is a Professor of Social Psychology at Arizona State University, and he lists six major ways you can make yourself persuasive. Auctions hit at least two of these six principles square on the nose.

First, auctions use the principle of scarcity, whereby we overvalue things that we think might run out. Auction items are scarce in that they are unique (only one person can have it), and scarce in time (after the bids are finished, you’ve lost your chance). Think how many shop sales successfully rely on scarcity heuristics such as “Last day of sale!”, or “Only 2 left in stock!”, and you’ll get a feel for how powerful this persuasion principle can be.

The other principle used by auctions is that of “social proof”. We all tend to take the lead from other people; if everybody does something, or says something, most of us join in before we think about what we really should do. Auctions put you in intimate contact with other people who are all providing social proof that the sale item is important and valuable.

A final ingredient in the magic-spell cast by auctions was uncovered by researchers from Princeton. Their experiments asked volunteers to play on-line auctions with different rules. Some of these auctions had rules that encouraged over-bidding (like typical open auctions, which most of us are familiar with from movies), and some had rules that encouraged rational behaviour (like the eBay structure). With enough guidance from the auction rules, the bidders didn’t end up paying much more than they originally thought was reasonable – but only if they thought they were bidding against a computer programme. As soon as the volunteers thought they were bidding against other live humans they found it impossible to bid rationally, whatever the auction rules.

This implies that the competitive element of auctions is crucial to provoking our irrational buying behaviour. Once we’re involved in an auction we’re not just paying to own the sale item, we’re paying to beat other people who are bidding and prevent them from having it.

So it seems Gore Vidal had human nature, and the psychology of auctions, about right when he said: “It is not enough to succeed. Others must fail.”

Fake pot industry generating novel, untested drugs

There’s an excellent article on the highs and increasing lows of the synthetic marijuana ‘legal high’ industry in the Broward Palm Beach New Times.

The piece is an in-depth account of how a legal high company called Mr. Nice Guy became the biggest fake pot manufacturer in the US.

It describes in detail how the business created and sold the product – only to fall foul of the rush ban on the first wave of synthetic cannabinoids.

The company was eventually raided by the Drugs Enforcement Agency and is waiting for the case to be tried in court. However, it’s still not clear whether they actually broke the law.

They changed their formula a few months before the raid to use two cannabinoids, called UR-144 and 5-fluoro-ur-144, which are not specifically covered by the current ban, so the prosecutors have to argue that they are close enough to the prohibited molecules to be illegal.

A curious point not mentioned in the article is that cannabinoid 5-fluoro-ur-144, also known as XLR-11, had never previously been described in the scientific literature and was first detected in synthetic marijuana.

It is listed by companies that sell research chemicals (for example, here) so you can buy it straight from the commercials labs.

But the data sheet makes it clear that structurally it is “expected to be a cannabinoid” but actually, it has never been tested – nothing is known about its effects or toxicity.

Previously, grey-market labs were picking out legal chemicals confirmed to be cannabinoids from the scientific literature and synthesizing them to sell to legal high manufacturers.

But now, they are pioneering their own molecules, based on nothing but an educated guess on how they might affect the brain, for the next wave of legislation-dodging drugs.

Fake pot smokers are now first-line drug testers for these completely new compounds.

Avoiding the shadows

The Lancet has a powerful essay on children born from rape and the social and psychological consequences for mother, child and community.

I’ll let the article speak for itself as it carefully articulates how the relationship between mother and child can be affected by these tragic events.

There is one point worth highlighting, however. The piece notes that when affected women do have contact with healthcare professionals, clinicians often avoid tackling problems with childcare because they are denied or ignored by the mothers who, understandably, find it difficult to address problems linked to such a violent and painful event.

The article notes that the wellbeing of the child is often not well addressed as “Many practitioners who care for women who have been raped maintain this silence because either their focus is on the well-being of the mother or they genuinely believe that the interests of the mother and child are not served by articulating relational difficulties”.

Mental health professionals rightly identify avoidance as one of the key factors that maintain problematic behaviours. It’s a strategy that places short-term comfort above longer-term well-being and we all use it, but when we rely it to manage serious emotional or behavioural difficulties it can mean we never recover.

But what is less admitted is that healthcare professionals also suffer from avoidance. We don’t like making people distressed, even when it is necessary to overcome serious difficulties. Consequently, we also avoid addressing painful issues, which is something that can also help maintain the problem in the person we are working with.

Ironically, it is very difficult to get healthcare professionals to recognise that they themselves are affected by this. We are much more comfortable when the problems are safely situated in the patient.

A comment on Szasz

One of the most interesting commentaries I’ve ever read on Thomas Szasz, the long-time critic of psychiatry who recently passed away, has been left as a comment in the obituary we recently published.

The comment is by ‘Aporeticist’ and he or she is clearly a fierce critic of modern psychiatry (to the point of indulging in sweeping generalisations at times) but the analysis of Szasz is remarkably insightful and cuts to the core of both his triumphs and failings.

Many of Szasz’s early critics have over the years quietly come around to some of his basic views. (Karl Menninger was one of his colleagues who acknowledged his change of heart.) The notion that the great majority of people with mental illness should never be hospitalized against their will (even when they are troublesome to those around them) has become common sense. It remains one of the great injustices of history that the psychiatric establishment continues to refuse to credit Szasz with being the first member of his profession who, in the mid 1960s, stated on record — against the unanimous opinion of his colleagues — the revolutionary contention that homosexuality was not a disease, and that it didn’t warrant “treatment” of any kind.

The classical liberal notion of “live and let live” resonates closely with the “first, do no harm” of the Hippocratic Oath that Thomas Szasz took as a young medical doctor. For better or worse, Szasz remained consistently faithful to these principles of negative freedom his whole life. Those, however, who believe that, as individuals and as a society, we have a moral obligation to (somehow) assist the mentally ill even when they don’t reach out for support, would regard Szasz’s characterization of psychiatric paternalism as “cruel compassion” as equally descriptive of his own apparent lack of concern for the welfare of those labelled mentally ill. Szasz tirelessly defended the autonomy of even the most severely disturbed mental patients (so long as they didn’t violate the law), yet seemed to care little whether they live or die if no one infringed on their sacred negative rights.

Recommended. Thanks Aporeticist.

Unwritten rules of the road

The latest edition of The Psychologist has a fantastic discussion on the psychology of how drivers, cyclists and pedestrians interact.

Rather appropriately, it’s with psychologist Ian Walker, who makes lots of interesting points about how different road users are perceived and how that affects behaviour.

…the lack of understanding of the cyclist outgroup seems to produce measurable changes in other road users’ behaviour. A few years ago I did a study which showed that changing the appearance of a cyclist led to notable changes in how much space drivers left when passing the bicycle. The specific changes seen make sense given the small body of research on non-cyclists’ stereotypes of cyclists. The two extant studies – the Lynn Basford et al. one, and research by Birgitta Gatersleben and Hebba Haddad, in 2010 – both found that non-cyclists view bicycle helmets as an indicator of an experienced rider, and in my data we saw riskier behaviour from drivers when they passed a cyclist who was wearing a helmet, which fits the idea they saw the rider as more capable.

The positive lesson from this, I feel, is that drivers do adjust their behaviour to the perceived needs of the non-drivers they are interacting with. The problem is that they do not always understand how to read these other people and judge their needs.

The whole issue of The Psychologist is a special and transport psychology and all of it is open-access this month.

Human Touch

A curious article has just appeared in the latest edition of the International Journal of Group Psychotherapy. The opening line of the summary is oddly delightful:

The group, with its intensity, interaction, roles and dynamics, is an important unit of experience in everyday life, in psychotherapy groups, and in Bruce Springsteen’s music.

The author, psychotherapist Lorraine Mangione, has written a previous paper on how “Bruce Springsteen is an eloquent spokesperson for the psychological journey through darkness, disconnection, and despair that many people experience, and for which they might look to professional psychologists for help.”

My own paper, ‘Firestarter: Deviant Behaviour and Psychopathy in the Music of The Prodigy’ is still a work in progress.

Hallucinations caused by lightning

A 23-year-old mountain climber was hit by a lightning bolt and awoke in hospital to find herself experiencing bizarre hallucinations.

The case, reported in BMJ Case Reports, describes how the healthy young woman was mountaineering with her climbing partner when they heard heard cracking thunder and were thrown to the ground by a massive shockwave.

The air rescue team took her to hospital and she was put in a drug induced coma for three days as she was disoriented and extremely agitated.

When she awoke, her world was somewhat different.

In the evening, still awake and 6 h after extubation, strange phenomena occurred. These exclusively visual sensations consisted of unknown people, animals and objects acting in different scenes, as if in a movie. None of the persons or scenes was familiar to her and she was severely frightened by their occurrence. For example, an old lady was sitting on a ribbed radiator, who then became thinner and thinner, finally vanishing through the slots of the radiator. Later, on her left side a cowboy riding on a horse came from the distance. As he approached her, he tried to shoot her, making her feel defenceless because she could not move or shout for help.

In another scene, two male doctors, one fair and one dark haired, and a woman, all with strange metal glasses and unnatural brownish-red faces, were tanning in front of a sunbed, then having sexual intercourse and afterwards trying to draw blood from her. These formed hallucinations, partially with delusional character, were in the whole visual field and constantly present for approximately 20 h. At the time of appearance, the patient was not sure whether they were real or unreal, but did not report them for fear that she might be considered insane. However, as she was still frightened after cessation of the hallucinations, she insisted on being transferred to her hometown hospital. Over the next few days, she had increasingly better insight and later forgot about this episode.

Her brain scan showed damage to the occipital lobes, the areas at the back of the brain that are largely taken up with the visual cortex that deal with the early stages of visual perception.

Luckily, the patient survived without sustaining any serious brain damage although the article mentions that because the occipital lobe has so many blood vessels “it could be particularly vulnerable to lightning damage”.

Thomas Szasz has left the building

The brilliant, infuriating, persistent, renegade psychiatrist Thomas Szasz has died.

Szasz is usually associated with anti-psychiatry but he rejected the label and really had nothing in common with the likes of R.D Laing, David Cooper and the rest. You can see this in his work.

He had two main arguments. The first was that the concept of ‘mental illness’ was really just a metaphor, in the same way that saying someone’s movie preferences were ‘sick’.

Because neither can be defined objectively and are a subjective interpretation of conscious states or behaviour, he excluded them from what can acceptably be called an illness.

The second stemmed from a political position. Szasz strictly adhered to a libertarian or classical liberal view of freedom and believed the only legitimate restriction of freedom should be the result of crime.

He saw psychiatry as a structure fundamentally built around restricting the freedom of ‘patients’ – the only branch of medicine to do so – meaning he thought it lacked legitimacy in both its aims and justification.

Most critics of psychiatry suggest that it doesn’t sufficiently ‘help’ people with psychological problems. Szasz saw this as promoting the idea of privileged helpers and medically-dependent patients.

Suggestions that psychiatry should not use drugs, should reject diagnoses, or should recognise some experiences as normal were an anathema to Szasz. The problem, according to him, was not the practices but a paradigm that allowed any restriction of freedom.

He was one of the most important critics of psychiatry not because he said it was done badly, but because he said it was incompatible with human liberty. A powerful reminder to a powerful profession.

But so much of it relied on buying into Szasz’s politics – and this was his major failing.

Szasz saw individual liberty as a pure and unalienable right while most see it as as important principle that should be balanced with the good of the community.

Different people draw the line in different places while Szasz is clearly on the extreme end of the spectrum.

He became famous with his book The Myth of Mental Illness in the 1960s when the extremes of personal freedom were popular, but as time has moved on Szasz’s politics have seemed increasingly out-of-place.

His association with Scientology through the CCHR or the ‘Citizens Commission on Human Rights’ made him look increasingly suspect as the organization lost its 60s counter-culture associations and became an intimidating corporate nonsense shop.

Szasz will surely be missed, however. He was active and writing right until the end of his life – never giving up on his campaign for extreme liberty.

One who studies the soul

i-D magazine has an interview with instrumental dubstep fusion maestro Psychologist. As part of the interview they asked him where the name came from and he gave quite a beautiful answer

What’s behind the name?

Literally, Psychologist means ‘one who studies the soul’, we think of it as a scary word in our harsh-sounding, Germanic language, but it actually means something really beautiful. I also like that it is ambiguous as to whether it’s me studying my own soul, or yours, or you studying my soul, or me asking you to study your own. It’s like a big impossible object that goes around and around.

If you want something of the more melodic side of Psychologist ‘Comes in Waves’ is a particularly beautiful track, while you can listen to an example of his unusual fusion style on the track ‘1:1’.

Deaf police to monitor security cameras in Mexico

Deaf police officers have been recruited to monitor security cameras in the Mexican city of Oaxaca because of their ‘heightened visual abilities’.

There’s a brief and somewhat clunky English-language news article from the local paper that describes the project:

Ignacio Villalobos Carranza, Deputy Secretary for the Ministry of Public Security of Oaxaca, said most of the monitoring of the 230 cameras is done by law enforcement officials that are hearing or speech impaired. He noted these police officers have a very strong deaf and visual sense and can better detect what is happening in different places where the cameras are located; they can often remotely read the conversations of people, to the benefit of this security system that operates 24 hours a day.

The ability to lip read conversations is a fantastic advantage, but the project raises the question of whether deaf people would actually be better at security monitoring in general.

As far as I know, there are no studies comparing hearing and deaf people on specific monitoring tasks but there is evidence that deaf people have certain advantages in visual attention.

This isn’t vision in general, such as having sharper visual acuity – where there seems to be no difference, but there is good evidence that deaf people are better at noticing things in the periphery of vision and detecting movement.

This potentially makes them perfect for the job and likely better than their hearing colleagues.

So the project turns out to be a targeted way not of recruiting ‘disabled people’ into the workforce, but of recruiting the ‘super able’. In fact, turning the whole idea of disability on its head.

There’s also a Spanish-language video report from BBC Mundo if you want more información.

Let there be light, finally

A documentary on the trauma of war, banned by the US government for more than 30 years, has found its way onto YouTube as a freely viewable video.

During World War Two, legendary director John Huston, then a fresh face in Hollywood, was commissioned to make three propaganda films for the US Army.

The third film, Let There Be Light, was made in 1946 – just as the war ended – and focussed on the psychiatric treatment of soldiers traumatised in combat.

This is a description from the fantastic book The Empire of Trauma:

With no political agenda, and anxious to keep scrupulously to the task he had been given, Huston applied to the letter the principle of objectivity he had followed in the two previous documentaries. For more than three months, he filmed the daily life of former combatants hospitalized at Mason General, a military hospital on Long Island. The courage and sense of sacrifice of these men was clearly portrayed, as the Pentagon had clearly requested. But equally apparent was the fact that some of them were utterly destroyed: their fear, their shame, and their tears showed clearly, as did their contempt for military authorities. The film also documented the arrogance and harshness of the psychiatrists and brutality of some of their therapeutic methods. Remarkably, when the film received its world premiere at the Cannes Film Festival in 1981, the emotional response of the viewers and critics was muted, for the film did not meet the expectations of an audience seeking revelations about the military and medical practices of the time.

What made the film so controversial in 1946, made it commonplace in 1981. But this was nothing to do with film-making, and instead concerned the way it portrayed the effects of trauma.

Let There Be Light portrays the “emotionally damaged” soldier as an everyday person “forced beyond the limit of human endurance”. “Every man”, it says, “has his breaking point”.

This is the modern view of trauma, widely accepted in psychiatry and in today’s media narratives, and is itself somewhat of a simplification of what we actually know about how people react to extreme events.

But in 1946, and especially in military psychiatry, the most widely accepted view was that soldiers who became mentally ill were psychologically weak or malingering.

The fact that film showed US Soldiers, not as the glorified heroes the public wanted, but as disabled veterans, meant that the film would be a huge propaganda disaster – likely compounded by the fact that most people saw these conditions as character flaws or shameful faking.

The idea that these were ordinary men who had been through extraordinary circumstances was just too far ahead of its time to seem realistic.

And this is why it was censored, for 35 years, until it had its first public showing in 1981, when it seemed nothing more than a passé propaganda film that just reflected what we all assumed was always the case, but actually, never was.

BBC Column: stopped clocks and dead phones

My column for BBC Future from last week. It’s another example of how consciousness isn’t just constructed, but is a construction for which the signs of artifice are hidden. The original is here

 

Ever stared at a second hand and think that time stands still for a moment? It’s not just you.

Sometimes, when I look at a clock time seems to stand still. Maybe you’ve noticed this to your bemusement or horror as well. You’ll be in the middle of something, and flick your eyes up to an analogue clock on the wall to see what the time is. The second hand of the clock seems to hang in space, as if you’ve just caught the clock in a moment of laziness. After this pause, time seems to restart and the clock ticks on as normal.

It gives us the disconcerting idea that even something as undeniable as time can be a bit less reliable than we think.

This happened to me for years, but I never spoke about it. Secretly I thought it was either evidence of my special insight to reality, or final proof that I was a little unhinged (or both). But then I found out that it’s a normal experience. Psychologists even have a name for it – they call it the “stopped clock illusion”. Thanks psychologists, you really nailed that one.

An ingenious experiment from a team at University College London recreated the experience in the lab and managed to connect the experience of the stopped clock to the action of the person experiencing it. They asked volunteers to look away and then suddenly shift their gaze to a digital counter. When the subjects tried to judge how long they had been looking at the digit that first appeared, they systematically assumed it had been on for longer than it had.

 

Filling gaps

Moving our eyes from one point to another is so quick and automatic that most of us probably don’t even think about what we are doing. But when you move your eyes rapidly there is a momentary break in visual experience. You can get a feel for this now by stretching your arms out and moving your eyes between your two index fingers. (If you are reading this in a public place, feel free to pretend you are having a good stretch.) As you flick your eyes from left to right you should be able to detect an almost imperceptibly brief “flash” of darkness as input from your eyes is cut off.

It is this interruption in consciousness that leads to the illusion of the stopped clock. The theory is that our brains attempt to build a seamless story about the world from the ongoing input of our senses. Rapid eye movements create a break in information, which needs to be covered up. Always keen to hide its tracks, the brain fills in this gap with whatever comes after the break.

Normally this subterfuge is undetectable, but if you happen to move your eyes to something that is moving with precise regularity – like a clock – you will spot this pause in the form of an extra long “second”. Fitting with this theory, the UCL team also showed that longer eye-movements lead to longer pauses in the stopped clock.

It doesn’t have to be an eye movement that generates the stopped clock – all that appears to be important is that you shift your attention. (Although moving our eyes is the most obvious way we shift our attention, I’m guessing that the “inner eye” has gaps in processing in the same way our outer eyes do, and these are what cause the stopped clock illusion.) This accounts for a sister illusion we experience with our hearing – the so-called “dead phone illusion”, which is when you pick up an old-fashioned phone and catch an initial pause between the dial tone that seems to last longer than the others.

These, and other illusions show that something as basic as the experience of time passing is constructed by our brains – and that this is based on what we experience and what seems the most likely explanation for those experiences, rather than some reliable internal signal. Like with everything else, what we experience is our brain’s best guess about the world. We don’t ever get to know time directly. In this sense we are all time travellers.

An in-brain stimulation grid

Implanted electrode grids are used to record brain activity in people who need neurosurgery – a technique known as electrocorticography.

But rather than just ‘reading’ from the brain, neuroscientists are starting to use them to ‘write’ to the brain, to the point of being able to temporarily simulate specific brain disorders for experimental studies.

This is the subject of my latest Observer column which looks at the history of open-brain stimulation studies and covers recent research by a joint British – Japanese team which has been using the grids to temporarily simulate a form of brain disorder called ‘semantic dementia’ in live volunteers.

The precision is such that the Lambon Ralph team and a team at Kyoto University Medical School, led by Riki Matsumoto, have used an implanted grid to temporarily simulate characteristics of a brain disease called semantic dementia. Like Alzheimer’s, semantic dementia is a degenerative disorder, but one in which brain cells that specifically support our understanding of meaning rapidly decline. Studies of patients with semantic dementia have taught us a great deal about how memory is organised in the brain but the disorder is swift and unpredictable, and a method that can mimic the effects while recording directly from the cortex is a powerful tool.

To be clear, the grids are not installed for this purpose. They’re installed because they are part of brain surgery to treat otherwise untreatable epilepsy. The grids allow neurosurgeons to locate the exact bit of the brain that triggers seizures so it can be removed.

The article is in part a coverage of the amazing neuroscience, from 1886 to the present day, and in part a tribute to the neurosurgery patients who have volunteered to help us understand the brain.

The kings of Kingsley Hall

The Observer has an article on some of the residents of R.D. Laing’s chaos-as-therapy residential centre at Kingsley Hall, five decades on.

The idea was that people with psychosis and therapists would live together in a therapeutic environment and effect change without the use of medical drugs. Residents could ‘live out’ their delusions and come to terms with the early traumas which R.D. Laing saw as the root of their difficulties.

But as the documentary Asylum shows, the place was more chaos than freedom, and the residence became a stop-in for hippies, lost souls and acid dealers.

Most accounts of the place have focussed on Laing but photographer Dominic Harris decided to track down the residents for a portrait project.

The Observer article has some of their stories:

One patient had been in a mental hospital: John Woods, I think. His label in orthodox psychiatry was paranoid schizophrenic. He had some fantasy about some young woman and he couldn’t write letters to her himself so he dictated them to me. When it turned out this woman wasn’t interested, he assumed wrongly that I was preventing her from coming to visit him. He thought I was a black magician and was controlling her. Then living in there became quite scary. There was a chapel in the building, with a huge crucifix, and he burst into my room early one morning holding it. I thought he was going to attack me with it but he wanted to exorcise me. Eventually, I did something that was against the whole ideology of the place: I tried to have him sectioned.

There are many more fascinating, if not troubling, insights to the heart of the chaos.

A pain to describe

RadioLab has an excellent mini-episode on the difficulties of communicating the subjective feeling of pain.

As you might expect, it is both wonderfully put together and unexpectedly beautiful in places, but for such a uncomfortable subject, it is also very funny.

Particularly wonderful is a segment on the originator of the Schmidt index that rates the intensity of insect sting pain from “Light, ephemeral, almost fruity” to “Pure, intense, brilliant pain”.
