Episode notes

The chapter explores how memories are constantly reshaped through retelling, leading to the original experience being obscured. It emphasizes the relationship between memory and intelligence, highlighting the importance of knowing what to memorize rather than memorizing everything. Drawing parallels between memory and computational systems, it discusses how Grandmaster chess players and basketball players utilize memory and strategy to excel in their respective fields.

"The only things that are important in life," declared the French filmmaker Jean Renoir, "are the things you remember." But what do we remember and why? That's the subject of a new book, "Why We Remember: Unlocking Memory's Power to Hold on to What Matters," by pioneering neuroscientist Charan Ranganath. He joins us today to explain why you still know the lyrics to the song you loved in eighth grade but can't remember the name of your kid's eighth-grade teacher, how memory shapes your identity, and what you can do right now to improve your recall.
