💎 On even seemingly inconsequential bits of friction in changing behaviour (to prevent suicides)

The extraordinary reductions in suicide resulting from changes in levels of carbon monoxide might have happened by accident, but the insight can be used to make deliberate changes that have reduced suicides. For example, a number of countries have introduced legal restrictions on the number of paracetamol tablets and similar everyday medications that can be bought in one go. There is not much to stop the determined buyer from going into several stores in a row and buying more pills, but it has been shown that in the UK alone such measure were associate with around 70 fewer suicides a year as a result of paracetamol ingestion (a 42 percent reduction), and an even bigger reduction of 61 per cent of patients needing a liver transplant as a result of damage from paracetamol. Similarly, there is evidence that where such pills are required to be sold in pop-out packs, rather than loose in a bottle, this also reduces suicide rates since the pills have to be taken out one at a time. A little friction, it turns out, is not always a bad thing.

💎 Don’t tell people, show them (how escalators became “normal”)

Then someone had a brilliant idea: proof always works better than a claim.

Don’t tell people, show them.

William ‘Bumper’ Harris was an employee who’d lost a leg in an accident.

He was told to come to Earl’s Court station and ride up and down the escalator.

Just that, ride up and down, nothing else.

People at the bottom would see a one-legged man with crutches nonchalantly hop onto the escalator and ride it to the top.

Then he’d turn around, and people at the top would see a one-legged man with crutches nonchalantly hop onto the other escalator and ride it to the bottom.

‘Bumper’ Harris just did that all day.

When frightened passengers saw him do it they were reassured an ashamed.

Reassured that if a one-legged man could do it anyone could.

And ashamed that they were ever frightened in the first place.

After a day of ‘Bumper’ riding up and down, everyone was using the escalator as if it was the most normal thing.

And once that happened, the problem disappeared.

Escalators became as accepted as the have been ever since.

The lesson was, it’s better to show people than to tell people.

💎 On how messages while drunk can have disproportionate effect (in promoting safe sex)

A group of Canadian psychologists led by Tara MacDonald recently went into a series of bars and asked the patrons to read a short vignette. They were to imagine that they had met an attractive person at a bar, walked him or her home, and ended up in bed — only to discover that neither of them had a condom. The subjects were then asked to respond on a scale of 1 (very unlikely) to 9 (very likely) to the proposition: “If I were in this situation, I would have sex.” You’d think that the subjects who had been drinking heavily would be more likely to say they would have sex — and that’s exactly what happened. The drunk people came in at 5.36, on average, on the 9-point scale. The sober people came in at 3.91. The drinkers couldn’t sort through the long-term consequences of unprotected sex. But then MacDonald went back to the bars and stamped the hands of some of the patrons with the phrase “AIDs kills.” Drinkers with the hand stamp were slightly less likely than the sober people to want to have sex in that situation: they couldn’t sort through the rationalization necessary to set aside the risk of AIDS. Where the norms and standards are clear and obvious, the drinker can become more rule-bound that his sober counterpart.

💎 On perspective blindness and the difficulties we have in adopting other people’s perspective (when buying gifts)

Why do guests do this? In 2011, Francesca Gino from Harvard and Frank Flynn from Stanford conducted an experiment to find out. They recruited ninety people and then allocated them to one of two conditions. Half became ‘senders’ while the other half became ‘receivers’. The receivers were then asked to go to Amazon and come up with a wish list of gifts priced between $10 and $30. Meanwhile, the senders were allocated to either choose a gift from the wish list, or a unique gift.

The result were emphatic. The senders expected that recipients would prefer unique gifts – ones they had chosen themselves. They supposed that recipients would welcome the personal touch. But they were wrong. Recipients would welcome the personal touch. But they were wrong. Recipients, in fact, much preferred gifts from their own list. The psychologist Adam Grant reports the same pattern with friends giving and receiving wedding gifts. Senders prefer unique gifts; recipients prefer gifts from their wedding list.

Why? It hinges upon perspective blindness. Senders find it difficult to step beyond their own frame of reference. They imagine how they would feel receiving the gift that they have selected.

💎 On the technique of assumption reversal for generating new perspectives and ideas (e.g Uber)

Michael Michalko, a former US army officer who has become a leader in creativity, advocates ‘assumption reversal’. You take the core notions in any subject or proposal, and simply turn them on their head. So, suppose you are thinking of starting a restaurant. The first assumption might be: ‘restaurants have menus’. The reversal would be: ‘restaurants have no menus’. This provokes the idea of a chef informing each customer what he bought that day at market, allowing them to select a customised dish. The point is not that this will necessarily turn out to be a workable scheme, but that by disrupting conventional thought patterns, it might lead to new associations and ideas.

Or, to take a different example, suppose you are considering starting a new taxi company. The first assumption might be: ‘taxi companies own cars’. The reversal would be: ‘taxi companies own no cars’. Twenty years ago, that might have sounded cray. Today, the largest taxi company that has ever existed doesn’t own cars: Uber.

💎 On the danger of not recognising the theories that guide your actions (as John Cleese notes)

John Cleese, the British comedian, put it this way: ‘Everybody has theories. The dangerous people who are not aware of their own theories. That is, the theories on which they operate are largely unconscious.’

💎 On the benefits of efficiency and the dangers of pursuing it too far (it’s worth being a little messy)

Sometimes (often actually) in business, you do know where you’re going, and when you do, you can be efficient. Put in place a plan and execute. In contrast, wandering in business is not efficient… but it’s also not random. It’s guided – by hunch, gut, intuition, curiosity … it’s worth being a little messy and tangential to find out way there. Wandering is an essential counterbalance to efficiency .. The outsized discoveries – the ‘non-linear’ ones – are highly likely to require wandering.

💎 On the absence of an authority figure liberating others to express their genuine opinions (leadership comes at a sociological price)

A clever study by the Rotterdam School of Management analysed more than three hundred real-world projects dating back to 1972 and found that projects led by junior managers were more likely to succeed than those with a senior person in charge. On the face of it, this seems astonishing. How could a team perform better when deprived of the presence of one of its most knowledgeable members?

The reason is that this leadership comes at a sociological price when linked to a dominance dynamic. The knowledge squandered by the group when a senior manager is taken out of the project is more than compensated for by the additional knowledge expressed by the team in his absence.

💎 On nothing in life being as important as you think it is while you are thinking about it (the focusing illusion)

I’ve been to several scientific conferences at which Professor Kahneman has spoken; and, when Daniel Kahneman talks, people listen. I am invariably among them. So I took special notice of his answer to a fascinating challenge to put to him not long ago by an online discussion site. He was asked to specify the one scientific concept that, if appreciated properly, would most improve everyone’s understanding of the world. Although in response he provided a full five-hundred-word essay describing what he called “the focusing illusion,” his answer is neatly summarized in the essay’s title: “Nothing in life is as important as you think it is while you are thinking about it.”

💎 On communication taking more of our time when technology makes it more efficient (Jevons’s paradox)

Today, information technology is changing the world making it more idea intensive, better connected, and ultimately more urban. Improvements in information technology seem to have increased, rather than reduced, the value of face-to-face connections, which might be called Jevons’s Complementarity Corollary. The nineteenth-century English economist William Stanley Jevons noted that more fuel-efficient steam engines didn’t lead to less coal consumption. Better engines made energy use effectively less expansive, and helped move the world to an industrial era powered by coal. The term Jevons’s paradox had come to refer to any situation in which efficiency improvements lead to more, not less consumption — one reason why low-calorie cookies can lead to larger waistlines and fuel-efficient cars can end up consuming more gas. Jevons’s paradox applied to information technology means that as we acquire more efficient means of transmitting information, like e-mail or Skype, we spend more, not less, time transmitting information.

💎 Sometimes words aren’t enough to change behaviour (demonstrations are more powerful)

At a school in the USA, the girls in their early teens had just discovered lipstick.

They would go into the female toilets to apply it.

Then, giggling, they’d leave imprints of their lips on the large mirror.

This made a lot of extra work for the cleaning staff.

The head teacher asked the girls to stop.

Of course, they ignored her.

So she took the girls to the toilets for a demonstration.

She said, ‘It takes a lot of work to clean the lipstick off the mirror.’

She said to the janitor, ‘Please show the girls how much work it takes.’

The janitor put the mop in the toilet, squeezed off the excess water and washed the mirror.

Then put the mop in the toilet again, and repeated the process. From that day on there was no more lipstick on the mirror.

That’s choice architecture.

💎 On problem solving using variation, survivability and selection (Palchinsky principles)

What Palchinsky realised was that most real-world problems are more complex than we think. They have a human dimension, a local dimension, and are likely to change as circumstances change. His method for dealing with this could be summarised as three ‘Palchinsky principles’: first, seek out new ideas an try new things; second, when trying something new, do it on a scale where failure is survivable; third, seek out feedback and learn from your mistakes as you go along. The first principle could simply be expressed as ‘variation’; the third as ‘selection’.

💎 On behavioural economics being an odd term (it’s just economics)

Behavioural economics is an odd term. As Warren Buffett’s business partner Charlie Munger once said, ‘If economics isn’t behavioural, I don’t know what the hell is.’ It’s true: in a more sensible world, economics would be a sub-discipline of psychology. Adam Smith was as much a behavioural economist as an economist – The Wealth of Nations (1776) doesn’t contain a single equation. But, strange though it may seem, the study of economics has long been detached from how people behave in the real world, preferring to concern itself with a parallel universe in which people behave as economists think they should.

💎 On how tolerating big mistakes can create the biggest learning opportunities (hypercorrection effect)

One of those desirable difficulties is known as the “generational effect.” Struggling to generate an answer on your own, even a wrong one, enhances subsequent learning. Socrates was apparently on to something when he forces pupils to generate answers rather than bestowing them. It requires the learner to intentionally sacrifice current performance for future benefit.

Kornell and psychologist Janet Metcalfe tested sixth graders in the South Bronx on vocabulary learning, and varied how they studied in order to explore the generation effect. Students were given some of the words and definitions together. For example, To discuss something in order to come to an agreement: Negotiate. For others, they were shown the only definition and given a little time to think of the right word, even if they had no clue, before it was revealed. When they were tested later, students did way better on the definition-first words. The experiment was repeated on students at Columbia University, with more obscure words (Characterized by haughty scorn: Supercilious). The results were the same. Being forced to generate answers improves subsequent learning even if the generated answer is wrong. It can even help to be wildly wrong. Metcalfe and colleagues have repeatedly demonstrated a “hypercorrection effect.” The more confident a learner is of their wrong answer, the better the information sticks when they subsequently learn the right answer. Tolerating big mistake can create the biggest learning opportunities.

💎 On expert predictions (beware)

The average expert was a horrific forecaster. Their areas of specialty, years of experience, academic degrees, and even (for some) access to classified information made no difference. They were bad at short-term forecasting, bad at long-term forecasting, and bad at forecasting in every domain. When experts declared that some future event was impossible or nearly impossible, it nonetheless occurred 15 percent of the time. When they declared a sure thing, it failed to transpire more than one-quarter of the time. The Danish proverb that warns “It is difficult to make predictions, especially about the future,” was right. Dilettantes who were pitted against the experts were no more clairvoyant, but at least they were less likely to call future events either impossible or sure things, leaving them with fewer laugh-out-loud errors to atone for — if, that was, the experts had believed in atonement.

💎 On the difficulty of making predictions (even by experts)

In separate work, from 2000 to 2010 German psychologist Gerd Gigerenzer compiled annual dollar-euro exchange rate predictions made by twenty-two of the most prestigious international banks — Barclays, Citigroup, JPMorgan Chase, Bank of America Merrill Lynch, and others. Each year, every bank predicted the end-of-year exchange rate. Gigerenzer’s simple conclusion about those projections, from some of the worlds most prominent specialists: “Forecasts of dollar-euro exchange rates are worthless.” In six of the ten years, the true exchange rate fell outside the entire range of all twenty-two bank forecasts.

💎 On dangerous unintended consequences that hamper vital (medical) innovation

A second, ironic, problem is that companies fear that if they produce a truly vital technology, governments will lean on them to relinquish their patent rights or slash prices. This was the fate of Bayer, the manufacturer of the anthrax treatment Cipro, when an unknown terrorist began mailing anthrax spores in late 2001, killing five people. Four years later, as anxiety grew about an epidemic of bird flu in humans, the owner of the patent on Tamiflu, Roche, agreed to license production of the drug after very similar pressure from governments across the world. It is quite obvious why governments have scant respect for patients in true emergencies. Still, if everybody knows that governments will ignore patents when innovations are most vital, it is not clear why anyone expects the patent system to encourage vital innovations.

💎 On attributing success to being committed rather than involved (in professional tennis)

Martina Navratilova was described as “the greatest singles, doubles, and mixed doubles player who’s ever lived.”

That was some compliment, coming from former World Number One player Billie Jean King.

This is what Marina had to say about commitment:

“Other players are involved in tennis, but I’m committed. It’s like ham and eggs. The chicken is involved; the pig is committed.”

💎 On the advantages of making small changes, rather than big ones (cheaper, faster, reversible)

Big doesn’t necessarily mean good. It could even be bad.

By contrast, there are tremendous advantages to making small changes.

Behavioural science has shown that tiny variations in phraseology can cause huge change.

Small changes are usually less costly, and often free.

Small changes attract less attention from bosses and meddlers, so they are easier to implement.

Small changes are easier to rectify if they don’t achieve their original objective.

So bear in mind that the ‘next big thing’ could be small.

💎 On idea generation (5 simple steps)

A guy named James Webb Young, a copywriter from the 1940s, laid out a five-step process of idea generation that holds water today.

1. You gather as much information on the problem as you can. You read, you underline stuff, you ask questions, you visit the factory.

2. You sit down and actively attack the problem.

3. You drop the whole thing and go do something else while your subconscious mind works on the problem.

4 . “Eureka!”

5. You figure out how to implement your idea.

💎 On how easy it is to forget we see the world from one particular perspective (when driving)

Naive realism suggests an answer: they do. It calls to mind a famous line of George Carlin’s: “Have you ever noticed that everyone driving slower than you is an idiot, and anyone going faster is a maniac?”

💎 Don’t confuse movement with progress (busyness is not a measure of productivity)

Some people, and businesses generally, love having lots of people rushing around.

It makes them feel productive.

Regardless of what they are doing, all the frenetic activity suggests that much helpful work is being done.

People even say sometimes that they like the buzz.

But it’s a bit like a goalkeeper diving to save a penalty.

He might be just as effective staying exactly where he is.

So movement doesn’t necessarily mean progress.

Don’t confuse the two.

💎 On the cumulative benefits of a simple idea across an entire ecosystem (saving chickens to inventing a new economy)

Paul Seward runs an NGA in Kenya called Farm Input Promotions (FIPS-Africa), dedicated to increasing the productivity of the local smallholder farmers, many of whom have just a quarter-acre of land. Seward discovered that if you paint the chicks blue, the eagles and hawks don’t realize what they are, and don’t try to eat them. The biodegradable paint washes off in ten weeks, by which time the chicks have enough yard-smarts to run for cover when they see a shadow overhead.

Because the farmers are losing fewer chicks to birds of prey, it is now more worthwhile for them to inoculate the young birds against disease. Through both of these measures, they have gone from a survival rate of 20 percent to close to 85 percent. Because the farmers have more chickens, they are eating more chickens themselves — and better nutrition means a healthier family. And because it is now a better business, more people are taking up chicken farming. Oh, and the idea has created an entirely new profession: chicken painters, who charge three Kenyan shillings to paint each chick. A fascinating example of the cumulative benefits of a simple idea across an entire ecosystem.

💎 No such thing as new ideas (only new combinations)

There is no such thing as a new idea. It is impossible. We simply take a lot of old ideas and put them into a sort of mental kaleidoscope. We give them a turn and they make new and curious combinations. We keep on turning and making new combinations indefinitely; but they are the same old pieces of coloured glass that have been in use through all the ages.

💎 Goodhart’s law and the unintended consequences of targets (in the former Soviet Union)

Consider Gosplan, the agency charged with central economic planning for the Soviet Union for most of the twentieth century. Their plans often involved setting economy-wide target amounts for commodities (wheat, tires, etc.), which broke down into production targets for specific facilities. In 1990, economist Robert Heilbroner described some of the complications with this system in “After Communism,” published in The New Yorker.

For many years, targets were given in physical terms — so many yards of cloth or tons of nails — but this lead to obvious difficulties. If cloth was reqarded by the yard, it was woven loosely to make the yarn yield more yards. If the output of nails was determined by their number, factories produced huge numbers of pin like nails; if by weight, smaller numbers of very heavy nails. The satiric magazine Krokodil once ran a cartoon of a factory manager proudly displaying his record output, a sing gigantic nail suspended from a crane.

Goodhart’s law summarizes the issue: When a measure becomes a target, it ceases to be a good measure.

💎 On the dangers of focusing on short-term efficiency (and the waggle dance)

There is a parallel in the behaviour of bees, which do not make the most of the system they have evolved to collect nectar and pollen. Although they have an efficient way of communicating about the direction of reliable food sources, the waggle dance, a significant proportion of the hive seems to ignore it altogether and journeys off at random. In the short term, the hive would be better off if all bees slavishly followed the waggle dance, and for a time this random behaviour baffled scientists, who wondered why 20 million years of bee evolution had not enforced a greater level of behavioural compliance. However, what they discovered was fascinating: with out these rogue bees, the hive would get stuck in what complexity theorists call ‘a local maximum’; they would be so efficient at collection food from known sources that, once these existing sources of food dried up, they wouldn’t know where to go next and the hive would starve to death. So the rogue bees are, in a sense, they hive’s research and development function, and their inefficiency pays off handsomely when they discover afresh source of food. It is precisely because they do not concentrate exclusively on short-term efficiency that bees have survived so many million years.

If you optimise something in one direction, you may be creating a weakness somewhere else.

💎 On the power of simplicity (in aviation and beyond)

The French aviator and author Antoine de Saint-Exupery once offered a definition of engineering elegance: “A designer knows he has achieved perfection not when there is nothing left to add, but when there is nothing left to take away.” A designer of simple ideas should aspire to the same goal: knowing how much can be wrung out of an idea before it begins to lose its essence.

Excerpt from: Made to Stick: Why some ideas take hold and others come unstuck by Chip Heath and Dan Heath

💎 On the dangers of relentlessly seeking cost-savings and efficiency (the doorman fallacy)

Business, technology and, to a great extent, government have spent the last several decades engaged in an unrelenting quest for measurable gains in efficiency. However, what they have never asked, is whether people like efficiency as much as economic theory believes they do. The ‘doorman fallacy’, as I call it, is what happens when your strategy becomes synonymous with cost-saving and efficiency; first you define a hotel doorman’s role as ‘opening the door’, then you replace his role with an automatic door-opening mechanism.

The problem arises because opening the door is only the notional role of a doorman; his other, less definable sources of value lie in a multiplicity of other functions, in addition to door-opening: taxi-hailing, security, vagrant discouragement, customer recognition, as well as in signalling the status of the hotel. The doorman may actually increase what you can charge for a night’s stay in your hotel.

When every function of a business is looked at from the same narrow economic standpoint, the same game is applied endlessly. Define something narrowly, automate or streamline it — or remove it entirely — then regard the savings as profit.

💎 On decision-making quality decreasing as the stakes rise (small versus large purchases)

After my first lecture, Binmore offered a version of the “low stakes” critique. He said that if he were running a supermarket, he would want to consult my research because, for inexpensive purchases, the things I studied might possibly matter. But if he were running an automobile dealership, my research would be of little relevance. At high stakes people would get stuff right.

The next day I presented what I now call the “Binmore continuum” in his honor. I wrote a list of products on the blackboard that varied from left to right based on frequency of purchase. On the left I started with cafeteria lunch (daily), then milk and bread (twice a week), and so forth up to sweaters, cars, and homes, career choices, and spouses (no more than two or three per lifetime for most of us). Notice the trend. We do small stuff often enough to learn to get it right, but when it comes to choosing a home, a mortgage , or a job, we don’t get much practise or opportunities to learn. And when it comes to saving for retirement, barring reincarnations we do that exactly once. So Binmore had it backward. Because learning takes practice, we are more likely to get things right at small stakes than at large stakes. This means critics have to decide which argument they want to apply. If learning is crucial, then as the stakes go up, decision-making quality is likely to go down.
