The rubber chicken that saved Pizza Hut | Nudge Newsletter 🧠

Toy motivation. In 1994, David Novak was promoted to Pizza Hut CEO. He wasn’t excited. "It was a graveyard for executives," he said. "Morale was down, business was down. It needed energy injected into the business.” The solution? A rubber chicken. Novak handed out a mini rubber chicken toy (and a relatively small cash bonus) to hundreds of high-performing employees. Not much of a gift, but a surprising impact. The tiny gift had a dramatic impact. "This took off like you wouldn't believe it...

It's not new. It's Black Friday today, and you'll undoubtedly see news articles and social posts lamenting modern-day consumers' unparalleled and insatiable demand. Yet, history suggests this isn't the case. David Grann shares what happened in Cherokee Outlet in 1893 in his book The Killers of the Flower Moon. “After the U.S. government purchased the land from the Cherokee, it announced that a settler would be able to claim one of the 42,000 parcels of land—if he or she got to the spot...

Well Done! You don't follow the crowd. Thank you for opening today’s email. Because psychology suggests you wouldn’t. There’s a psychological principle known as negative social proof. Definition = if you make an unwanted behaviour seem commonplace, more people will perform the unwanted behaviour. Few examples: “Visitors steal 5 tons a year” increased wood theft at an Arizona park (Cialdini, 1984) “Many miss their NHS appointments” increased no-shows (Martin, 2024) “Over 1,000 people will...

The best of Seth Godin I’ve got a bit of a love/hate relationship with Seth Godin’s books. A lot of it is fluff, but there are some pearls of wisdom. Penguin Magic Seth calls PenguinMagic.com the “Amazon for magic tricks.” So, how did this family-run site achieve such a feat? Well, by leveraging the curiosity gap. Humans are drawn to incomplete information, we love cliffhangers and click on clickbait. Penguin Magic must know this. Their website contains thousands of tricks, each with...

KFC or ZFC? This KFC ad is much-praised online. Yet, I think it's misguided. By promoting imitation fried chicken shops, I think KFC is doing something they might regret. To explain, I need to share a study. Titled: To be in Vogue, the researchers analyzed adverts from years in Vogue magazine for this study. The researchers wanted to see if middle-brow fashion brands could raise their prices if they competed with high-end brands like Gucci. In other words, is the Halo Effect so powerful that...

Bowles' bowl cajole. In the runup to Prince Charles' and Camilla Parker Bowles' April 2005 wedding, souvenir sales were disappointingly low. Shops from London to Windsor reported sluggish sales of tea towels, coffee mugs, and commemorative bowls. The British public wasn't fussed. But then overnight, demand changed. Suddenly, sales sky-rocketed, with Brits cleaning out shops and buying up all available stock. Did Brits suddenly change their opinions? No, the date changed. At time of writing,...

Handwritten triumphs. It's safe to say I'm obsessed with Rory Sutherland's Nudgestock talk. He shares this surprising house-buying tactic. This family of 5 wanted to buy a house in Chesterfield. So, they wrote a handwritten letter to the 25 houses on their street. This strange, ineffective tactic probably won't work, right? No. 8 people responded. 5 people offered viewings 4 people gave them offers. 1 sold them their house. And yet, 0 previously had their homes on the market. This handwritten...

"We'd be ÂŁ11m richer." Take a look at this ad. Credit to Joe Rampley for sharing this on LinkedIn. It's jam-packed with behavioural science principles designed to persuade Londoners to use the product. Let's break it down. "10 minutes free daily." The Power of Free We're drawn to free things. The difference between a chocolate that costs 1 cent and 0 cents is dramatic. The free version increases purchase intention by 69% (*Ariely, 2008). "ÂŁ11 million richer by now" Costly Signalling. Rory...

My interview mistake A few years back, I was asked to interview for a Director of Product Marketing role. The recruiter emailed me and asked when I would like to interview. "First, last or somewhere in the middle?" Being the behavioural science nerd I am, I decided to go first. Why? The primacy effect suggests that the first interview will stick more in the mind than others. The Serial Position Effect study (Glanzer & Cunitz, 1966) showed that words listed first had a higher recall than...

A secret bestseller. Do you recognise this football player? Probably not. He's only played for England once. And yet. This fairly unknown English footballer sold more books than David Beckham, Michael Owen, Steven Gerrard, and Frank Lampard combined. He did so using the curiosity gap. He wrote under a pseudonym, "the Secret Footballer". By hiding his identity, he could share hard truths, gossip, and uncensored stories, such as the drunken antics of a Chelsea striker or the binge-eating winger...
