💎 On the power of a small first commitment (foot-in-the-door)

In the mid-1960s psychologists Jonathan Freedman and Scott Fraser published an astonishing set of data. They reported the result of an experiment in which a researcher, posing as a volunteer worker, had gone door to door in a residential California neighborhood making a preposterous request of homeowners. The homeowners were asked to allow a public-service billboard to be installed on their front lawns. To get an idea of just how the sign would look, they were shown a photograph depicting an attractive house, the view of which was almost completely obscured by a very large, poorly lettered sign reading DRIVE CAREFULLY. Although the request was normally and understandably refused by the great majority (83 percent) of the other residents in the area, this particular group of people reacted quite favorably. A full 76 percent of them offered the use of their front yards.

The prime reason for their startling compliance has to do with something that had happened to them about two weeks earlier: They had made a small commitment to driver safety. A different volunteer worker had come to their doors and asked them to accept and display a little three-inch-square sign that read BE A SAFE DRIVER. It was such a trifling request that nearly all of them had agreed to it. But the effects of that request were enormous. Because they had innocently complied with a trivial safe-driving request a couple of weeks before, these homeowners became remarkably willing to comply with another such request that was massive in size.

💎 On the benefits of getting customer feedback on prototypes (as early as possible) rather than the finished product

The level of feedback you get is so much more valuable and impactful… The problem with showing something to consumers when it’s almost totally done, people don’t necessarily want to give negative feedback at that point because it looks like, “This company has spent a lot of money already getting it to this stage and now I’m going to tell them, ‘It sucks.’ ” On the other hand, if something hangs together with tape, and it’s clear that it’s an early prototype, the mindset of consumers often is, “These people still need some help, so let me tell you what I really think about it.”

💎 On our desire for variety being greater at purchase not consumption (think All-Bran in cereal variety packs)

We also seem to crave more variety at the point of decision than we will actually desire down the road. When I was young, for example, I was obsessed by the Kellogg’s variety packs of cereal. Wooed by the sight of the Apple Jacks and Frosted Flakes jostling up against each other, I would clamor for my parents to buy the largest package on offer, a towering block of shrink-wrapped goodness. Having raced through my favorites, however, I would find my liking gradually diminishing, from dizzy Applejacks heights to the sad denouement of a few sparse clusters of Special K and All-Bran, which often went unconsumed, dying a slow death in a shroud of plastic. My parents would, of course have been better off simply buying a few boxes of my favorites, which I would reliably eat every day.

💎 On personalisation being nothing new (YOUR COUNTRY NEEDS YOU)

So they ran a recruitment poster.

But the visual didn’t show massed ranks of soldiers.

With the headline, ‘THE BRITISH ARMY IS SHORT OF TWO MILLION NEW RECRUITS’.

The visual was Kitchener pointing out of the poster, straight at the person looking at the poster.

And the headline said, ‘YOUR COUNTRY NEEDS YOU’.

One-to-one.

And that poster worked.

It got millions of recruits.

By talking to people one at a time.

It was so successful the USA copied it a few years later with a picture of Uncle Sam and the same headline.

And it recruited millions of men there, too.

💎 On the power of prestige (name versus quality)

Of the twelve journals, only three spotted that they had already published the article. This was a grave lapse of memory on the part of the editors and their referees, but then memory is fallible; however, worse was to come. Eight out of the remaining nine articles, all of which had been previously published, were rejected. Moreover, of the sixteen referees and eight editors who looked at these eight papers, every single one stated that the paper they examined did not merit publication. This is surely a startling instance of the availability error. It suggests that in deciding whether an article should be published, referees and editors pay more attention to the authors’ names and to the standing of the institution to which they belong than they do to the scientific work reported.

💎 On the secret behind the world’s first aspirational root vegetable (scarcity)

Scarcity is a great way to make something seem more attractive and valuable. The Blues Brothers famously played ‘for one night only’ and Bernd Pichetsrieder, the great BMW marketing guru insisted on ‘always selling one less than you can’.

This kind of strategy is sometimes called the ‘velvet rope’ – ‘you can’t come in’ often makes something that much more appealing. This was also the trick behind the story of how Frederick the Great turned Prussia into a potato eating nation – he insisted that no-one but the nobility could eat the potato. The ‘aspirational’ root vegetable? Believe it.

💎 On the tendency to interpret information to fit with our own behaviour (smoking and lung cancer)

My personal favourite from Festinger’s many brilliant examples of cognitive dissonance deals with people’s beliefs about the link between smoking and lung cancer. He was writing at the very birth of research on the causes of cancer. It was a unique window of time during which it was possible to test whether groups of smokers and non-smokers would accept or reject new information that had been uncovered about a link. Festinger saw the effects you’d expect from anyone suffering cognitive dissonance: heavy smokers – those who had the most to lose from the new research being right – were the most resistant to believing that a link had been proven; only 7 per cent accepted the validity of the new research. Twice as many moderate smokers accepted the link, at 16 per cent. Non-smokers were much more willing than smokers to believe the link had been proven, but as a mark of just how far social norms have swung since then, only 29 per cent of them believed the link had been proven, despite having nothing to lose.

💎 On the power of choice architecture in determining what we eat (eat your Broccoli, kids)

Wansink moved broccoli to the beginning of the line. The first thing hungry students now saw wasn’t fast food. Fruit was taken out of functional containers and put in an attractive wooden bowl. The salad bar went in front of the tills, making it more prominent, something you couldn’t avoid. The ice cream freezer went from invitingly transparent to opaque. Buying sugar-rich desserts was made more complex, requiring additional calculations. Wansink hadn’t actually added anything, the food on offer was the same, but he rearranged the process. The results were clear.

Broccoli consumption increased by 10-15 per cent. Fruit sales from the wooden bowl doubled. Sales of salad tripled. The percentage of students buying ice cream fell from 30 per cent to 14 per cent. In general the composition of meals was far healthier. Arrangement, not any other inducement, led to healthy eating. Wansink studied other instances of how food’s presentation and arrangement affects our relationship with it.

💎 On the power of personalised messages (especially images)

Recently, the Behavioural Insights Team began altering the letter sent to British citizens if they failed to pay taxes on their car. The traditional letter was all text, informing the subject that if they didn’t pay now they would be hit with various penalties, including a clamped or and hefty fines. To increase the effectiveness of the letter, the scientists began experimenting with various forms of personalization. The first variant involved making a more specific threat, telling recipients that they would lose their particular model of car if they didn’t pay the tax. The second variant featured a personalized visual, so that the letter came attached with a photograph of the actual car question. While both approaches increased compliance, the customized picture was the most effective—it increased the compliance rate from 40 to 49 percent.

💎 On going that little bit further than the competition to tip the pitch odds in your favour (personalisation can win the deal)

In 2005 a flagging Japanese economy convinced Takashi Hashiyama, president of the electronics firm Maspro Denkoh, to sell the corporate collection of French impressionist paintings This included a major Cezanne landscape and lesser works by Sisley, van Gogh, and Picasso. Both Christies and Sotheby’s gave presentations to Hashiyama touting their expertise and ability to achieve the highest auction prices. In Hashiyama’s judgment, the presentations were equally convincing. To settle the matter, he proposed a game of rock, paper, scissors.

“The client was very serious about this,” Christie’s deputy chairman Jonathan Rendell said, “so we were very serious about it, too.” The money was serious, too. The Maspro Denkoh collection was valued at $20 million. Both Christie’s and Sotheby’s quickly agreed to the game.

In contrast, Kanae Ishibashi, the president of Christie’s Japan, began researching RPS strategies on the Internet. You may or may not be surprised to learn that an awful lot has been written on the game. Ishibashi had a break when Nicholas Maclean, Christie’s director of impressionist and modern art, mentioned that his eleven-year-old twin daughters, Alice and Flora, played the game at school almost daily.

Alice’s advice was “Everybody knows you always start with scissors.” Flora seconded this, saying “Rock is way too obvious… Since they were beginners, scissors was definitely the safest.”

Both girls also agreed that, in the event of a scissors-scissors tie, the next choice should be scissors again — precisely because “everybody expects you to choose rock.”

Ishibashi went into the meeting with this strategy, while the Sotheby’s rep went in with no strategy at all. The auction house people sat facing each other at a conference table, flanked by Maspro accountants. To avoid ambiguity, the players wrote their choices on a slip of paper. A Maspro executive opened the slips. Ishibashi had chosen scissors, and the Sotheby’s representative had chosen paper. Scissors cuts paper, and Christie’s won. In early May 2005, Christie’s auctioned the four paintings for $17.8m, earning the auction house a 1.9m commission.

💎 On social proof being a helpful shortcut (best-seller lists)

So we use others as a helpful shortcut. A filter. If a book is on the best-seller list, we’re more likely to skim the description. If a song is already popular, we’re more likely to give it a listen. Following others saves us time and effort and (hopefully) leads us to something we’re more likely to enjoy.

Does that mean we’ll like all those books or songs ourselves? Not necessarily. But we’re more likely to check them out and give them a try. And given the thousands of competing options out there, this increased attention is enough to give those items a boost.

Knowing others liked something also encourages people to give it the benefit of the doubt. Appearing on the best-seller list provides an air of credibility.

💎 On our tendency to seek news that confirms what we already know (we get uncomfortable with new things)

Be careful. People like to be told what they already know. Remember that. They get uncomfortable when you tell them new things. New things . . . well, new things aren’t what they expect. They like to know that, say, a dog will bite a man. That is what dogs do. They don’t want to know that man bites a dog, because the world is not supposed to happen like that. In short, what people think they want is news, but what they really crave is olds … Not news but olds, telling people that what they think they already know is true.

💎 On our present preference bias (to boost pension saving rates)

The ‘Save More Tomorrow’ programme tackles both of these barriers head-on by, first, auto-enrolling people onto workplace saving schemes to combat inertia. People are obviously completely free to opt back out, but, human nature being what it is 90 per cent stay on the scheme, with their inertia now working for them rather than against them. An auto-escalator then ups the contributions, not immediately but over time (the tomorrow bit). This shifted the reluctant hugely: when asked whether they would up their contributions now by five percentage points, most said no (we need the chocolate now). But when asked whether they’d commit to saving more in the future, 78 per cent said yes.

The impact of ‘Save More Tomorrow’ has been substantial. Before the programme, the average saving rate for workers in the sample was 3-5 per cent, but after four years this had increased nearly four-fold to 13.6 per cent.

💎 On new and revolutionary products (our opinions of them change as we age)

There’s a set of rules that anything that was in the world when you were born is normal and natural. Anything invented between when you were 15 and 35 is new and revolutionary and exciting, and you’ll probably get a career in it. Anything invented after you’re 35 is against the natural order of things.

💎 On resisting the impulse to tinker with marketing approaches (paying not to change)

There was a perhaps apocryphal tale about a time when Reeves was out sailing with a client. The client made bold to ask why he should continue paying the same fee when the ad was never really changed. “What do you need all those people on my account when you never do anything?” Reeves, who could be surly, gruffed, “To keep your people from changing what I’ve done.”
