open.spotify.com
In the 'Remarkable People' podcast, Guy Kawasaki introduces Dr. Charan Ranganath, a UC Davis professor and director of the Dynamic Memory Lab, who has authored the book 'Why We Remember'. The book delves into the selective nature of memory, challenging traditional views and incorporating Ranganath's research involving brain imaging and computational modeling. Ranganath shares personal anecdotes, such as his diverse guitar collection which includes acoustic, bass, baritone, and electric guitars, each inspiring different musical styles and songs. He values the tactile feel of guitars, particularly electrics, over their sound. Despite owning surfboards, Ranganath admits to being a poor swimmer and living far from the coast, having not surfed since completing his book. Kawasaki, on the other hand, started surfing at 60. Kawasaki recounts a New Year's Eve boat experience, prompting a discussion on why intense emotional experiences become memorable. Ranganath explains that emotional intensity bolsters memory retention and that retelling stories can embellish memories, often transforming them into narratives rather than factual recollections. He also likens forgettable experiences to memories overshadowed by similar ones, with factors like emotional blandness and predictability leading to forgetting. Ranganath humorously recalls a memorable TSA agent due to his theatrical behavior and suggests that we are predisposed to forget most things, particularly meaningless information. The conversation touches on the selective nature of memory retention, with Kawasaki joking about remembering Ranganath for his guitar collection. They reflect humorously on what will be remembered from their interview. Kawasaki also mentions using unique methods to be memorable. The discussion moves to the reliability of eyewitness testimony, with Ranganath explaining the complexity of memory in such scenarios, including the 'other race bias' in facial recognition and the impact of repeated mugshot viewing on witness certainty. He warns that AI face recognition systems can inherit human biases. Ranganath acknowledges that susceptibility to false memories varies, with children and the elderly being more prone, and that factors like alcohol, fatigue, and stress can increase this susceptibility. He argues that most people's memories can be 'corrupted' by leading questions and explains that memory is a mix of fragments and current beliefs, forming a narrative. Kawasaki and Ranganath also discuss the influence of skillful questioning on memory.
