Many people report that their attention spans have diminished—but what if you can rebuild your concentration skills? Gloria Mark is a professor of informatics at UC Irvine who studies the impact of digital media on people’s lives. In this episode, Gloria joins Adam to dig into her research on multitasking, interruptions, and focus, sharing insights on why we’re so easily distracted and how to train your brain to improve concentration. Gloria also answers a question from historian Daniel Immerwahr, a past Re:Thinking guest, and makes the case for moderation as a more effective prescription than a full digital detox.
