Three thousand years ago, Odysseus tied himself to a mast to resist the Sirens.  He didn't trust his willpower, so he removed the choice entirely.  Today, Owain Service, co-founder of the Behavioural Insights Team and CEO at CogCo, calls that a commitment device.  And modern evidence shows it works for everything from saving money to staying married. --- Owain’s book: https://amzn.to/4smVtrP  Owai...

Most restaurants have a major problem.  Paying the bill.  Give the bill too early, and the customer feels rushed. Too late, and they feel ignored.  To solve this problem (and many more), Will Guidara turned to behavioural science.  And his solution helped his restaurant become the world’s best. ---  Listen to the bonus episode: ⁠https://nudge.kit.com/aeea58886f⁠  Will’s book Unreasonable Hospitali...

In 2015, the media became obsessed with one man’s attempts to grow tea in the Scottish Highlands.  The BBC profiled him on the One Show. Radio reporters flocked to interview him. Even the Chinese national news agency reported his work.  Tam O’Braan (as he was then known) was the first to ever sell Scottish tea, and the press went wild.  Fornum and Mason bought his leaves. The Dorchester created a...

Do nine-ending prices really work?  Will £9.99 sell more than £10.00? Can it be used for high-quality products? What about hedonic products?

16 years ago a chain of Chinese restaurants wanted to increase sales without changing the price.  They didn’t change the product.  The service.  The chef.  The food.  Instead, they changed two words on their menu and increased sales by 18%.  The restaurants used the advice of today’s guest on Nudge, Robert Cialdini.  Today, Cialdini explains the social proof principle, sharing how changing just tw...

“Say you’ve calculated your price and it comes out at £120,121.  Most would round it down to £120,000.  That’s completely wrong.”  That’s what Robert Cialdini told me on the latest episode of Nudge.  He also explained why the Prime energy drink first succeeded and then flopped.  How Disney kept us hooked on classic movies.  And how he applies the authority bias to sell his own products.  ---  Unlo...

KFC keeps its recipe secret.  It’s stored in a vault in an unknown location.  Only two KFC executives know the ingredients.  Neither are allowed to fly on the same plane.  But this secrecy is illogical. The recipe isn’t important.  Today on Nudge, Richard Shotton explains how the secrecy makes customers more loyal.  He shares his favourite ad of all time, and we run one of his experiments on you. ...

In 1963, the Milgram experiments revealed something unsettling.  Most people kept administering what they believed were painful electric shocks, not because they wanted to, but because they couldn’t bring themselves to say no.  In this episode, my guest shares why we agree to extra projects, unpaid favours and unreasonable requests even when we know we shouldn’t.  I’m joined by behavioural scienti...

2 out of 3 internet users in the USA pay for Prime.  Yet, most of them are irrationally loyal.  They feel like the subscription provides more cost savings than reality.  Today, on Nudge, Richard Shotton and I explore the behavioural science behind Amazon Prime.  We look at the sunk-cost fallacy and pennies-a-day effect to explain why so many are irrationally loyal to Amazon Prime.  ---  Subscribe...
