Hi everyone, and welcome back to The Kara Goldin Show! Today’s guest is someone who literally wrote the book on how one tiny-ass button changed the whole damn world. I’m joined by Martin Reeves, Chairman of the BCG Henderson Institute and co-author of LIKE: The Button That Changed the World.
You’ve tapped it. You’ve chased it. You’ve felt the dopamine hit. But what’s the real story behind the “like” button? In this episode, Martin and I dive deep into the origins of the iconic thumbs-up, how it became the foundation of today’s attention economy, and the unexpected ripple effects it’s had on business, mental health, and even artificial intelligence. We talk about how this seemingly simple feature changed the way we measure validation, shaped entire industries, and taught us what not to overlook when launching innovation in a tech-saturated world.
If you’re curious about the intersection of psychology, business, and technology—and how small signals can drive massive behavior—you won’t want to miss this one. Now on The Kara Goldin Show.
