A 3-year old beat a PhD engineer at an engineering problem while playing legos—and that single moment kicked off a decade of research that exposed one of the strongest, most underrated biases in the human brain: we almost never subtract.

This week, Michael sits down with Dr. Leidy Klotz — University of Virginia engineering professor, former pro soccer player, and author of Subtract, which explored why your brain defaults to adding when removing is the better answer.

His new book In a Good Place, unpacks why open offices steal your focus, the science of the “home field advantage” and why the spaces you live in might be quietly running your life (and even affecting  your lifespan).
