    Can one text message save 100s of girls from cervical cancer? Today on Nudge, Niall Daly and Dr Giulia Tagliaferri discuss their county-wide study involving 55,000 girls. Their experiment had some eye-opening results, so I decided to copy it. I ran my own study on my listeners to see if I could increase my sales. Did it work? Listen to find out.

  • I debunked psychology’s greatest myth

    I debunked psychology’s greatest myth
    Jun 23 2025
    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?
