Julia Shaw: Criminal Psychology of Murder, Serial Killers, Memory & Sex | Lex Fridman Podcast #483

Criminal psychologist Julia Shaw explores the complexities of human evil, memory, and sexuality, advocating for empathy, critical thinking, and a nuanced understanding of human behavior to make society safer and happier.

• Human 'evil' is a continuum of psychological traits, not a binary state, and everyone has the capacity for harmful acts.

• Memories are highly malleable and prone to distortion, requiring critical awareness and external documentation for accuracy.

• Empathy, destigmatization, and understanding diverse human behaviors are crucial for a safer, more inclusive society.

Julia Shaw, a criminal psychologist, discusses how 'evil' is a continuum of traits rather than a binary state, emphasizing that all humans have the capacity for harm and that understanding psychological drivers is key to prevention. She highlights the malleability of human memory and the importance of open conversations about sexuality and non-traditional relationships. Shaw also applies her expertise to environmental crime, arguing that an empathetic, scientific approach can lead to more effective solutions for global challenges.

Human Capacity for Evil

• 00:00:00 Most people, including over 70% of men and 50% of women, fantasize about killing someone, suggesting a universal capacity for violence. This challenges the notion that 'evil' is an inherent trait, as individuals are not born evil but rather develop the capacity for extreme harm through various influences. The focus should be on understanding why most people do not act on these fantasies, rather than demonizing those who do.

Dark Tetrad Traits

• 00:02:05 The 'Dark Tetrad'—psychopathy, sadism, narcissism, and Machiavellianism—represents a continuum of personality traits rather than a binary classification. Everyone scores somewhere on these scales, which describe characteristics like pleasure in hurting others (sadism), self-interest (Machiavellianism), self-admiration (narcissism), and lack of empathy (psychopathy). Scoring high on multiple traits increases the likelihood of harmful behavior, but these traits exist on a spectrum, often subclinically.

Empathy and Dehumanization

• 00:05:19 The word 'evil' is problematic as it dehumanizes individuals, preventing understanding and fueling conflict. Dehumanization, coupled with de-individuation (seeing oneself as part of a group), is crucial for large-scale atrocities like war, where both sides often perceive themselves as 'good' fighting 'evil.' Cultivating 'evil empathy'—understanding the psychological and social factors leading to severe crimes—is essential for making society safer by addressing root causes rather than merely labeling individuals.

Psychology of Murder

• 00:37:43 Contrary to sensationalized media portrayals, most murders are not pre-planned acts by 'psychopaths' but rather impulsive reactions to trivial disputes or arguments that escalate out of control. Society's desire for extreme reasons behind extreme consequences leads to a misperception of murder, ignoring that common motives can be as simple as small debts or stolen items. Recidivism for murder is low, highlighting a potential mismatch between public perception of justice and effective crime prevention strategies.

Understanding Incels

• 00:43:09 The psychology of incels, and other groups exhibiting harmful behavior, often stems from a sense of entitlement and anger when perceived societal expectations are not met. When individuals feel entitled to a specific life, such as a traditional family structure, and this is unfulfilled, it can lead to dissatisfaction and a propensity for dangerous actions. Online echo chambers can further reinforce these negative views, making individuals more dangerous by validating their anger and sense of injustice.

Malleability of Memory

• 01:38:14 False memories are a common feature of a normal, healthy brain, not a glitch, meaning every autobiographical memory has some degree of falsehood. Memories are not static but are creatively recombined and optimized for gist rather than verbatim detail, making them susceptible to distortion by leading questions or suggestive information. Even brief social interactions, or exposure to AI-generated content, can profoundly modify memories, making critical thinking and immediate external recording crucial for accuracy, especially in legal contexts.

Neuroscience of Memory

• 01:54:57 Memory functions like a Wikipedia page, constantly edited by new experiences, social interactions, and even self-suggestion. This dynamic nature means memories are not fixed but can be intentionally modified through techniques like cognitive restructuring to foster a more positive outlook on past events, promoting resilience and happiness. While this flexibility allows for personal well-being, it also underscores the ease with which memories can be distorted, as demonstrated by the ability to implant false memories of entire events within short interactions.

Non-Monogamy & Bisexuality

• 01:51:26 Monogamy, often a social construct, does not align with actual human behavior, with research consistently showing many people cheat. This suggests exploring non-traditional relationship structures like polyamory can be a healthier alternative for some. Bisexuality is frequently misunderstood as a 'phase' or a stepping stone to being gay, but it is a valid sexual orientation often characterized by attraction regardless of gender. Open communication and acknowledging a spectrum of sexual and relationship preferences are vital for individual happiness and societal acceptance.
