💎 On there being no magic number of times an activity needs to be done to fix a bad habit (just keep doing it)

Contrary to popular belief, there isn’t a magic number of repetitions that result in a habit forming. Some say that you need to repeat an action fifty times or for twenty-one days, but very few researchers have actually looked at this question systematically. And those that have done tend to find that there isn’t a clear-cut answer to the question. In one of the few studies to have tracked the formation of healthy habits in real-world settings, researchers studied ninety-six students who had just moved to university and were encouraged to repeat behaviours in response to consistent cues (such as ‘going for a walk after breakfast’). They found that habits formed in some of the students after eighteen days, but for some it took much longer – up to 254 days. The average was sixty-six days.

💎 On photos of people with dilated eyes are more attractive (but men are not sure why)

In a recent experiment, men were asked to rank how attractive they found photographs of different women’s faces. The photos were eight by ten inches, and showed women facing the camera or turned in three-quarter profile. Unbeknownst to the men, in half the photos the eyes of the women were dilated, and in the other half they were not. The men were consistently more attracted to the women with dilated eyes. Remarkably, the men had no insight into their decision making.

💎 On how rewards can crowd out intrinsic motivation (encouraging people in relation to tasks they dislike)

To test this theory, a few years ago I ran a study in which two groups of people were asked to take part in an experiment in which they spent an afternoon picking up litter in a London park. Participants were told that they were taking part in an experiment examining how best to persuade people to look after their local parks. One group were paid handsomely for their time, while the others were only given a small amount of cash. After an hour or so of backbreaking and tedious work, everyone rated the degree to which they had enjoyed the afternoon. You might think that those clutching a large amount of well-earned cash would be more positive than those who had given their time for very little money.

In fact, the result was exactly the opposite. The average enjoyment rating of the handsomely paid group was a measly 2 out of 10, while the modestly paid group’s average ratings were a whopping 8.5. It seemed that those who had been paid well had thought, ‘Well, let me see, people usually pay me to do things I don’t enjoy. I was paid a large amount, so I must dislike tidying the park.’

💎 On the value of operational transparency in product design

For example, the bright red Powerball in Finish dishwashing tablets, as well as the salient red centre of Anticol’s medicated throat lozenges, illustrates “this is the hardworking bit.” When we see these products there’s no question in our minds where the unique value or effort is. They’re practically radioactive. As Rory Sutherland writes in Alchemy, the same is true of striped toothpaste.’ Psychologically, the red, blue and white coloured stripes give us a clear signal that the toothpaste is performing more than one function, aiding the belief that this single toothpaste can offer the trifecta of strong teeth, fresh breath and …

💎 On Oasis creatively avoiding having to issue refunds

When technical glitches marred their Manchester concert in June 2009, mega-band Oasis turned to the symbolic power of a signature to rescue them. Recognising the gig’s disruptions, the band sent out an eye watering 1m pounds worth of cheques in reimbursement. “People can obviously cash them in,” a spokesperson told the Manchester Evening News after the band offered the crowd a refund. Their genius? Anticipating that fans would never take them to the bank, every cheque was hand signed by Oasis frontmen Liam and Noel Gallagher. With pen and ink alone, the band saved themselves a fortune.

💎 On the importance of timely feedback

For example, the clever people from Dulux paint recognised that an absence of visual feedback also wreaks havoc for exhausted DIYers looking to decorate white ceilings with white paint (it’s near impossible to know where you have already painted!).

Addressing this issue, Dulux created NeverMiss, a ceiling paint that goes on pink (providing clear feedback against white ceilings) and dries white, helping painters create a uniform finish. Likewise, to prevent ‘creepers’ edging over the speed limit, radar-enabled speed displays providing real-time feedback now reduce speeding by up to 10%. There are nappies that signal when they’re soiled, tissues that change colour when you’re nearing the end of the box, razorblades that turn green when it’s time to change the blades, and even tyres that wear away to reveal the message “change tyre” when your tread becomes dangerously thin.

💎 On how putting numbers in perspective makes them more memorable

Two scientists at Microsoft Research, Jake Hofman and Dan Goldstein, believe in this idea so strongly that they’ve spent the better part of a decade spearheading a project known as the Perspectives Engine with a simple goal: develop tools that make numbers easier for humans to understand.

Microsoft’s search engine, Bing, delivers millions of facts a day in response to queries. The Perspectives team wondered whether some simple contextual phrases would help people understand and remember their numerical search results.

So they did something basic: Instead of just reporting that Pakistan has an area of 340,000 square miles, they added a brief “perspective phrase,” something like “that’s about the size of 2 Californias.” And then, at time scales ranging from a few minutes later to a few weeks later, they tested people to see if they remembered the fact they had been shown.

Some perspective phrases were better than others. Simpler comparisons from more familiar states or countries led to better memory for the facts. But ALL phrases were better than nothing. Even a slightly unwieldy comparison was more effective than a number alone.

💎 On reframing pressure as a privilege as a way to deal with anxiety

King soon began to see that the same principle — that pressure privilege — applied to all kinds of situations and that her anxiety was sign of her motivation to succeed. ‘Great moments carry great weight — that is what pressure to perform is all about. And though it can be tough to face that kind of pressure, very few people get the chance to experience it.’ With that realisation, she saw that she should embrace rather than suppress feelings of stress — a mindset that allowed her to get through her first Grand Slam wins and the enormous media hype around the Battle of the Sexes match against Bobby Riggs in 1973. As she wrote in her memoir, ‘At first, I felt obligated to play Riggs, but I chose to embrace as a privilege the pressure that threatened to over’ whelm me. This changed my entire mindset and allowed me to deal with the situation more calmly. And as time went on, I began to see the match as something I got to do instead of something I had to do. The shy fifth-grader who feared that she would die from her nerves at public speaking became one of our greatest athletes and one of sports most prominent spokespeople.

💎 Rituals may have a benefit because they quell anxiety by giving sense of control

One study of free throws in basketball found that players were around 12.4 percentage points more accurate when they followed their personal routines before the shot than when they deviated from the sequence. Overall, the total success rate was 83.8 per cent with the exact routine, compared to 71.4 per cent without. 39 Superstitions and rituals can also boost perseverance and performance across a whole range of cognitive tasks, and the advantages are often considerable.

💎 Information isn’t interpreted neutrally, but in line with our existing opinions

The Power of Confirmation

Three scientists, Charles Lord, Lee Ross, and Mark Lepper, recruited forty-eight American undergraduates who either strongly supported the death penalty or strongly opposed it. They presented them with two scientific studies; one offered evidence regarding the effectiveness of capital punishment, and the other data showed its ineffectiveness. In reality, the studies had been fabricated. Lord, Ross, and Lepper had made them up, but the students did not know that. Did the students find the studies convincing? Did they believe that the data provided good evidence that should alter their minds? They did!

But only when the study reinforced their original view. Those students who strongly supported capital punishment thought the study that demonstrated its effectiveness was well conducted. At the same time, they argued that the other study was poorly executed and not compelling. Those who were originally against capital punishment assessed the studies the other way around. As a result, believers in the death penalty left the lab supporting capital punishment with more passion than ever, while those in opposition to it ended up opposing capital punishment with more zest than before.
