The broken windows theory suggests that one broken window can cause a neighbourhood to descend into disrepair. But is it true? Today, with the award-winning professor Leidy Klotz, we investigate the broken windows theory and explain how environments shape our behaviour. --- Become an FSB member: https://get.fsb.org.uk/nudge/ Leidy’s book Subtract: https://amzn.to/4df4duk Leidy’s latest book In a Good Place: https://amzn.to/4tzjCvE Join 11,934 readers of the Nudge Newsletter: https://www.nudgepodcast.com/mailing-list Unlock the Nudge Vaults: https://www.nudgepodcast.com/vaults Connect on LinkedIn: https://www.linkedin.com/in/phill-agnew/ --- Today’s sources: Brown, G., & Baer, M.

“How we used nudges reach £12 billion in sales” Octopus Energy's Pete Miller

Octopus Energy went from £0 in revenue to £12 billion in 10 years. Today, on Nudge, I chat with their first employee Pete Miller, who explains how they used nudges to grow. Hear why they: 1) Encourage customers to spin a wheel to reward metre readings. 2) Give away free electricity at 4pm. 3) Play you the number one song from the year you turned 14. 4) And gave away 40,000 electric blankets during an energy crisis. --- Become an FSB member: https://get.fsb.org.uk/nudge/ Unlock the Nudge Vaults: https://www.nudgepodcast.com/vaults Subscribe to my newsletter: https://www.nudgepodcast.com/mailing-list Connect on LinkedIn: https://www.linkedin.com/in/phill-agnew/ --- Today’s sources: Shampanier, K., Mazar, N., & Ariely, D.

Enhanced Games: Did the $320m marketing stunt backfire?

The Enhanced Games, hosted in Las Vegas last Saturday, made a bold claim. With the use of performance-enhancing drugs, enhanced athletes would break not just personal records but world records. And the end goal? To sell those same drugs to the masses. It’s arguably the biggest marketing stunt of the year so far, and today on Nudge I reveal the psychology behind it. Did the Enhanced Games succeed?

What makes a good logo?

In this episode, I chat to Pete Miller, part of the co-founding team at Octopus Energy, who helped design one of the most recognisable new logos in Britain. Hear how Octopus used two proven psychological principles to build a logo people remember (and why those same principles are being ignored by most of the industry). You'll learn: - Why a distinct logo made one beer taste 5% better - How a 1933 German study explains why Octopus stands out - Why brands from McDonald's to KFC give their logos human faces - And what happened when researchers asked people to turn off a robot --- Subscribe to my newsletter: https://www.nudgepodcast.com/mailing-list Unlock the Nudge Vaults: https://www.nudgepodcast.com/vaults Connect on LinkedIn: https://www.linkedin.com/in/phill-agnew/ Read Aaron’s book: ⁠https://thethingswelove.com/⁠ --- Today’s sources: Bartneck, C., Van Der Hoek, M., Mubin, O., & Al Mahmud, A.

Why willpower alone doesn’t work

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 Owain’s company CogCo: https://cogco.co/ Unlock the Nudge Vaults: ⁠https://www.nudgepodcast.com/vaults⁠ Join 11,626 readers of my newsletter: ⁠https://www.nudgepodcast.com/mailing-list ⁠ Connect on LinkedIn: ⁠https://www.linkedin.com/in/phill-agnew/⁠ --- Today’s sources: Asch, S.
