Andrew Huberman interviews Cal Newport, a Georgetown computer science professor and author of Deep Work and Slow Productivity, on science-backed tools for focus, productivity, and avoiding burnout. They discuss Newport's practices, drawing from his MIT training and research on attention, task-switching, and knowledge work.

Digital Tools and Distraction Costs

Newport keeps a smartphone without social media apps, treating it as a basic phone, music player, and maps tool from 2007—far less compelling without engineered attention-grabbers. He stores it away during work in dedicated spaces like a tech-free library for writing, surrounded by curated books and a fireplace. Phones nearby trigger task-switching, which incurs a 15-minute cognitive ramp-up cost per switch; frequent checks (e.g., email every 5 minutes per RescueTime data) create constant "cognitive disorder," reducing output more than time spent checking.
