  • Why We’re Irrationally Loyal to Amazon Prime

    Why We’re Irrationally Loyal to Amazon Prime
    Dec 8 2025
    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 to the Nudge Vaults: https://www.nudgepodcast.com/vaults Read Richard’s book: https://a.co/d/fEW7amQ 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/ --- Today’s sources: Arkes, H.
