How would you encourage sustainable behaviour?  You might assume logical messages work best.  Stuff like “the average three-hour flight creates ~250–400 kg of CO₂”.  But today’s guest on Nudge has tested logical messages.  And they don’t work.  Today on Nudge, Toby Park from the Behavioural Insights Team explains how renaming a meat-free dish doubled its sales. Why targeting home-movers made Americans 400% more likely to cycle. How social norms can increase sales by 20%. And the reframing led the majority of Brits to choose energy-efficient fridges.  ---  Watch the bonus episode: https://nudge.kit.com/27720ca0ad Connect with Toby on LinkedIn: https://www.linkedin.com/in/toby-park-67773279/  Read Toby’s Net Zero Report: https://shorturl.at/Wy8RP How to Build a Net Zero Society: https://shorturl.at/0PcRk Sign up for my newsletter: https://www.nudgepodcast.com/mailing-list  Connect on LinkedIn: https://www.linkedin.com/in/phill-agnew-22213187/  Watch Nudge on YouTube: https://www.youtube.com/@nudgepodcast/  --- Sources:  Das, G., Spence, M.

Super Mario Bros is 40 years old. It’s an incredibly simple game (it takes up the same memory as a smartphone wallpaper), yet it’s incredibly popular. Over 40 million people have played it. Why?

Today, Ramli John explains the subtle behavioural science tricks Super Mario games use to keep us playing. ---  Ramli’s book EUREKA: https://www.delightpath.com/book/eureka Ramli’s website: https://www.delightpath.com/ Subscribe to the (free) Nudge Newsletter: https://nudge.ck.page/profile Connect on LinkedIn: https://www.linkedin.com/in/phill-agnew/ Watch Nudge on YouTube: https://www.youtube.com/@nudgepodcast/ Visit the new website: https://www.nudgepodcast.com/ ---  Sources:  Alter, A.

I interviewed 60 Brits to debunk one of psychology’s greatest myths. Priming is one of the best-known biases in behavioural science. Kahneman mentions it 35 times in his best-selling book Thinking Fast and Slow. And yet, I’m not convinced it really works. In five separate experiments, I tested it. Does priming work, or is it a myth?  The studies:  Authenticity study: https://ibb.co/5W14DM2N Creativity study: https://ibb.co/FbxxNMDf Guilty study: https://ibb.co/XrTLXrY4 Anchoring + priming study: https://ibb.co/99LLw7G9 Reading time study: https://ibb.co/LDYc18yF ---  Subscribe to the (free) Nudge Newsletter: https://nudge.ck.page/profile Connect on LinkedIn: https://www.linkedin.com/in/phill-agnew-22213187/ Watch Nudge on YouTube: https://www.youtube.com/@nudgepodcast/ Learn more about Voxpopme: https://www.voxpopme.com/ ---  Sources:  Bargh, J.
