NUDGE, NUDGE, WINK, WINK

Lose weight! Make better choices! Increase savings! Is there anything that nudges can’t help us do?

Imagine this scenario: You’re running late for a meeting. So, you edge the speedometer just over the limit and phone your client to let them know. That’s two things you’ve done knowing full well that they’re against the rules. That’s precisely why traditional economics doesn’t always work. It supposes that humans always act rationally — which means, in this instance, that a person racing against the clock will accept that they’re just going to have to face the consequences. It ignores the fact that this may be an important meeting, that maybe you’re feeling jittery and reckless after a caffeine fix, and that actually you’d rather get a fine than face missing out on a potential opportunity. Behavioural economics recognises this, though — it knows us for the fallible, fickle creatures we are.

It’s this discipline that gave rise to the theory of nudges, widely popularised in the books Nudge: Improving decisions about wealth, health and happiness by Richard Thaler and Cass Sunstein and

Thinking Fast and Slow by Daniel Kahneman.

What’s a nudge? It’s the idea that, instead of enforcing rules and regulations, governments and organisations should exert an ever-sogentle pressure on individuals to get the results they desire.

Here’s a good one: instead of getting heavy-handed with fines and posters threatening litterbugs, the Danish government addressed its litter problem by creating a trail of green footprints leading up to rubbish bins in public places.

Here’s another you’ve probably experienced personally: You’ve finally reached the end of your shopping list, you’re feeling tired and in need of a boost — and, look, there’s a chocolate bar on the shelf just in front of you.

Nudges can work the other way, too. Say you’ve finally come to terms with the fact that your gym contract is never going to be used, and decide the money you spend on it can be put to better use. You phone the call centre to cancel, but the process you have to follow is such a rigmarole you decide it’s actually easier to let things lie.

That’s the problem with nudges, according to Vincent Hofmann of BetterWork: although the theory may have been designed with the best of intentions, you can’t ignore the fact that it works by leveraging our human frailties — in this instance, laziness. More than that, most of the time we don’t even realise that we’re being nudged; that our environments have been fashioned by “choice architects”

It’s a shock to think that your decisions have been informed by someone else

who have set a stage to subtly guide our behaviour so that it ultimately serves their aims.

There’s no denying that, seen from that view, it’s all a little creepy, sinister even — if not downright disempowering. After all, it’s a shock to think that your decisions — about everything from what you buy to what you do with your money — have been informed by someone else.

That’s something that worries Claire Denham-Dyson, an anthropologist at Demographica. “Before I entered the marketing industry, I didn’t know there were so many people thinking about the way I make decisions.” Her concern has not diminished over time, but she has come to see the other side of the argument. “The reality is that decision-making involves a significant degree of emotional and mental energy. If you can save the end user that energy so that it can be invested elsewhere, that’s to their benefit.” She’s quick to add a but: if you’re selling a product or service that offers little value to the end user, or which is harmful, the subtle manipulation of nudges is inexcusable.

Amateur behaviourist and founder of Green Edge Communications, Hugh Tyrell, who uses his insights in his work as a separation-at-source recycling consultant, acknowledges that there will always be a tension between the interests of the seller and the consumer. But that doesn’t mean that nudges should be dismissed, he argues. Behavioural economics, and nudges in particular, are of particular help to entities that need to understand that a person’s behaviour — whether related to buying, saving or anything in between — are probably influenced more by their conversations around the water cooler than by their budgets.

It’s how marketers use this understanding that makes all the difference, maintains Hofmeyer de Beer of JvR Africa. “Ultimately, nudges are value-neutral. They become negative only if used for a negative purpose. There’s a fine line between manipulation and influence, and companies that are entirely profit- driven find it easy to justify any action. But it’s important that they are mindful of how their actions affect people.”

Of course, the same could be said for us as consumers. Even if choice architects weren’t deliberately playing on our subconscious desires to make some options more attractive than others, we’d automatically be drawn to anything which enhances our preferred image of ourselves. Paying better attention to the things we choose, and considering why we’ve chosen them, shifts us from passive playthings to active participants. After all, a nudge loses its effectiveness if you’re fully cognisant of the carrot being dangled in front of you.
