I shrunk Britain’s favourite bread and showed it to a dozen Brits from Bolton. I was experimenting with shrinkflation. Companies shrink the size of their products without changing the price, benefiting from a psychological bias that means we struggle to notice small changes. Today, chatting with Grace Forell from Which?, I figure out the psychology behind shrinkflation, why it works, and I test if anyone notices my shrunken loaf of bread.

Today, I try to persuade 20 total strangers to listen to Nudge. To help, I’ve asked Brain Ahearn for advice. Brian’s Tedx talk on pre-suasion has been viewed by over 1 million people. He teaches tactics that anyone can use. So, I put his advice to the test. I’ve found 40 strangers and asked them if they’d listen to Nudge, but for 20 I used Brian’s ‘pre-suasion’. Did it work? Tune in to find out.

What makes us happy? This question generates wildly different answers. I asked four Nudge listeners and got four different answers. Being the behavioural science nerd I am, I’ve always wondered if there is a scientific answer to this question. Is there a study that reveals the secrets behind the good life?

Yes, there is. It’s the longest study on human happiness ever conducted. Today, I spoke to Marc Schulz, the associate director of that study, and he shared the results.

Robert Cialdini is known to most as the godfather of influence. But is his 40-year-old book still relevant? Today, with Bas Wouters, best-selling author and CEO of the Cialdini Influence, we debate whether Cialdini’s 1984 findings still apply.

I’ve spent hundreds of hours playing Nintendo Brain Training. I’ve always thought it’d make me smarter. Most people agree. I asked 25 Brits, and 24 said it “helps their memory.” And yet, my guest on Nudge, Prof Dan Simons, thinks we’re all wrong. So, does Nintendo brain training work? Well, in today’s episode of Nudge, I find out. 

First, I analysed the dozens of ads Nintendo had put out. I share the psychological nudges they used to persuade us and how they made their game so popular. Then, I run my own experiment. For 5 days, I play Nintendo Brain Training. I record my progress and measure if my intelligence has improved after a week. And finally, I chat with Professor Dan Simons and hear why he thinks so many people like me were lured in by Brain Training’s claims.

Tesco is the largest UK employer. They conduct almost 1 million interviews a year, yet I think they might be pointless. Today, I will share psychological studies showing common interview flaws.
