EPISODE SUMMARY

In this episode of Lex Fridman Podcast, featuring Julia Shaw and Lex Fridman, Dr. Julia Shaw on Lex Fridman: Why murder fantasy is normal explores inside Evil: Julia Shaw On Murder, Memory, Sex, and Green Crime Lex Fridman and criminal psychologist Julia Shaw explore how so‑called “evil” behaviors exist on a psychological continuum rather than in a good–evil binary, focusing on the dark tetrad traits and why ordinary people can commit extraordinary harm. They discuss false memories, lie detection, serial killers, murder fantasies, jealousy, kinks, bisexuality, and non‑monogamy, emphasizing empathy and nuance instead of moral panic. Shaw explains her research showing how easily false criminal memories can be implanted, and why this matters for police interviews, therapy, AI systems, and personal wellbeing. In the final part, she introduces her work on environmental crime, arguing that corporate and ecological offenders are best understood through the same psychological lenses as other criminals, and that tech and social science together can be used to prevent harm.
