Every day, you make thousands of choices, but what if most aren’t really yours? My research in Sweden showed something incredible: when we sent vaccination letters instead of text messages, we saw more people show up to get vaccinated. Same vaccine, except we used paper instead of phones. This is the hidden power of ’nudging’ – how tiny changes in how choices are presented can completely change what we decide. Netflix auto-plays the next episode, snacks sit at eye level, and TikTok videos keep you scrolling – nudges are everywhere.

In this lightning talk, I will reveal the invisible psychology shaping your daily decisions and show you how others secretly influence your choices. You will start seeing every app, menu, and product differently. Warning: once you understand nudging, you can never unsee it. But that’s actually a superpower – you will finally understand why you choose what you choose!
