Chapter 1: Year of the Rabbit, London
Bringing behavioural science out of the lab and into real life
Can you remember what first piqued your interest in nudging? For April, it was when a lecturer during a Psychology seminar asked the class to take out their matriculation cards and write down the last two digits of their student ID number.
âNow, Iâd like you all to write down how much youâd be willing to pay for this lovely vintage,â the lecturer said, pointing to an image of a bottle of wine projected onto the whiteboard.
Amazingly, each class memberâs bid for the bottle was affected by the student number theyâd written down moments before. Despite being completely irrelevant to the value of the wine, this arbitrary number had served as an anchor for their subsequent judgements of value. The surprise at having the anchoring effect brought to life in this way was, frankly, unforgettable. Having fallen for this psychological bias moments before, it was impossible to deny the existence of the effect.
The start of anyoneâs journey with behavioural science begins with a light-bulb moment, realising the counterintuitive and often humorous ways in which human behaviour is susceptible to nudging. It follows that if you want to get other people excited about applying behavioural science, you need to create these light-bulb moments. And to create that light-bulb moment you must move beyond the often dry academic case studies, to bring behavioural science to life in a way which feels relevant to peopleâs lives.
Imagine that youâre trying to explain the beauty of applied behavioural science to someone at a party. You want to capture their imagination by telling them the classic story of the fly in the urinal at Amsterdamâs Schiphol airport. You could try explaining it to your new friend as follows:
âTo test a hypothesis that male attention could be directed into a particular domain by re-establishing a new environmental context, we did a randomised controlled trial with men in operational hygiene facilities. We found that the simple etching of an image on the urinal motivated them to hit the desired target, thus changing their behaviour and reducing urine spillage.â
Alternatively, you could add some colour to the story:
âFrom personal experience, most men I pass in the airport toilets tend to be incredibly bored, incredibly drunk, or often a combination of both. And that means that they pay little attention to weeing in the toilet, so often end up weeing on the floor. But, if you etch a fly onto the bowl of the urinal, men subconsciously aim for it, which reduces spillage by 80%.â
Which story would you rather hear? The second version is more likely to trigger the light-bulb moment, as your listener can relate to it more easily. Rather than blinding people with science, however impressive it is, get them excited by helping them to appreciate the applications of behavioural science in relation to their own lives, their roles at work, or their relationships.
Knowing that this was the case, this is exactly what Jez set out to do when launching a behavioural science practice within Ogilvy, the global advertising agency.
âWhy should I care about behavioural science?â
The year was 2011 and Jez was an Integrated Strategy Director. Having worked closely with Rory Sutherland, who was Vice Chairman of Ogilvy, together they wanted to launch a team whose sole purpose was to apply behavioural science to advertising. Theyâd settled on the name Ogilvy Change and now needed to get their colleagues as excited about behavioural science as they were. In order to get the rest of the company to embrace behavioural science, they needed to capture their colleaguesâ imaginations.
One option would have been to spend an hour lecturing about various heuristics and biases. They could have told them about how in America there is a wonderful âSave More Tomorrowâ programme developed by academics, which found that behavioural economics could be used to increase peopleâs savings from their salary from 3.5% to 13.6% over 40 months.
Alternatively, they could have talked about how The Economist had engineered its subscription choice architecture in order to generate more print and digital sales. Would-be subscribers had the option of a $59 digital subscription, a $125 print subscription, or a $125 print and digital subscription. Who would choose the print-only subscription, when for the same price you could get online access? Indeed, Dan Ariely found that with this decoy option, significantly more people chose the more expensive package. But without the print-only option, significantly more people chose the cheaper, digital-only option. Proof, right there, that our decisions are influenced by choice architecture and that behavioural science can have big impacts on business outcomes.
If theyâd taken this route to convert colleagues into behavioural science enthusiasts, they might have got through to a couple of them at best. And this, in the early days of the field, is where it often fell down. Many of the learnings from behavioural science are theoretical and the challenge in a business context is bringing the application possibilities to life.
Similarly, itâs ironic that books such as the New York Times Best Seller Thinking, Fast and Slow, written by one of the forefathers of behavioural economics, was specifically written to appeal to an academic audience. The book was published with small, hard to read text, and very few pictures. Who knows how many more copies it may have sold had it also been published in a more populist format? Chunked into several books, with a bigger text size and plenty of pictures, this would have conveyed the virtues of behavioural science to a lay audience in a more engaging way.
The Year of the Rabbit
Instead of a lecture, Jez and Rory set out to conduct a series of playful studies in the agency to bring the applications of behavioural science to life. It was the Chinese Year of the Rabbit and so their experiments were all tied to this theme. Could they make people eat like rabbits, move like rabbits, bounce like rabbits and copulate like rabbits? Whilst these studies were inspired by findings from academic journals, their versions were far from being academically robust. But for their purpose this didnât matter. The point was to bring the theories to life and to demonstrate the ways in which behavioural science could be used to nudge behaviour.
Eating like rabbits
Their first experiment was conducted in the agency canteen, where they set out to nudge their colleagues to eat more carrots. We are more likely to choose healthy foods if they are easy to reach, or first in line. For example, one study found that the location of desserts had a significant effect on whether customers in a hospital cafeteria chose the healthy or unhealthy options, with people more likely to choose the dessert that was easy to reach. In order to nudge their colleagues to eat more carrots, therefore, they moved the carrots earlier in the canteen line and doubled the quantity normally available. They also changed the description of the carrots to ...
