Lex Fridman PodcastDr. Julia Shaw on Lex Fridman: Why murder fantasy is normal
Why most people harbor murder fantasies that never become behavior; the dark tetrad places psychopathy and sadism on spectrums everyone occupies.
CHAPTERS

Evil as a continuum: the dark tetrad and why labeling people ‘evil’ ends inquiry
Julia Shaw and Lex Fridman frame “evil” not as a binary category but as gradations of traits—psychopathy, narcissism, Machiavellianism, and sadism. They discuss why labeling people as evil can ‘other’ them and shut down curiosity, empathy, and prevention-focused thinking.
- •Dark tetrad traits defined and treated as continuous dimensions
- •Clinical vs subclinical traits and why most people sit somewhere on the spectrum
- •‘Evil’ as an unhelpful label that ends conversation and enables dehumanization
- •The more useful question: why most people do NOT commit severe harm
- •Humanizing perpetrators as a prerequisite to prevention
- 3:46 – 7:37
Baby Hitler, nature vs nurture, and the social mechanics of atrocity
The classic ‘kill baby Hitler’ thought experiment becomes a vehicle for discussing whether people are born bad or shaped by environment. They connect this to war: dehumanization and deindividuation make ordinary people capable of extraordinary cruelty.
- •Baby Hitler question as a proxy for beliefs about innate evil
- •Shaw’s rejection of ‘born evil’ and emphasis on developmental trajectories
- •War psychology: dehumanization + deindividuation (us vs them)
- •Both sides in war construct moral narratives of good vs evil
- •Empathy collapse as a mechanism enabling mass violence
- 7:37 – 22:45
‘Evil empathy’ and interviewing stigmatized people without becoming their PR
Shaw argues empathy toward perpetrators is not endorsement—it’s a tool to understand causal pathways and reduce harm. They explore how to interview controversial leaders or convicted criminals while accounting for self-serving narratives, rationalizations, and platforming concerns.
- •Empathy as an instrument for prevention, not absolution
- •Rationalization and normalization in offender narratives (“everyone’s doing it”)
- •Even controlled narratives reveal psychology and motives
- •True crime ethics: fame incentives, anonymization, and coverage choices
- •How scientists’ ‘puzzle mindset’ can seem callous but adds nuance
- 22:45 – 37:07
Serial killers: loneliness, reality monitoring, and dark-trait mixtures
Using Robert Pickton and other infamous cases, they discuss how isolation can erode ‘reality monitoring’ and allow extreme ideation to develop unchecked. They connect serial offending to mixtures of dark tetrad traits and distorted goal pursuit.
- •Pickton case as disturbing example and career influence
- •Loneliness and lack of social tethering as risk factors
- •Reality monitoring: social networks help correct delusions and drift
- •Serial motives can include warped intimacy/partner fantasies (e.g., Dahmer)
- •Extreme behavior as a magnified version of common human feelings plus additional factors
- 37:07 – 41:13
Why people murder: boring motives, escalation, and low homicide recidivism
Shaw challenges media myths: most murders are not carefully plotted by ‘monsters’ but are impulsive escalations from arguments, petty disputes, or risky behavior. They discuss the ‘victimization gap,’ how societies demand dramatic motives for dramatic outcomes, and why homicide repeat rates are relatively low.
- •Common murder origins: fights that escalate, trivial disputes, impulsivity
- •Media preference for sensational serial-killer narratives
- •Victimization gap: asymmetry between victim loss and perpetrator consequences
- •Homicide recidivism often estimated very low (1–3%)
- •Prevention vs retribution tensions in sentencing and public perception
- 41:13 – 43:05
Justice, forgiveness, and restorative models vs ‘tough on crime’ instincts
The conversation turns to how justice systems should respond if the goal is safety rather than vengeance. Shaw distinguishes forgiveness (a victim-family choice) from policy design, and highlights restorative justice as a pathway for meaning-making, accountability, and prevention.
- •Forgiveness belongs to victims’ families; policy is a separate question
- •Restorative justice: apology, explanation, repair, and understanding
- •Youth violence and gangs: perpetrators can be ‘kids’ too
- •Deterrence and risk management should guide sanctions if safety is the goal
- •Societal punishment often aligns with moral intuitions more than risk profiles
- 43:05 – 50:01
Lies, scams, and entitlement: incels, love fraud, coercive control
They explore deception outside courtrooms—incel ideology as entitlement amplified by online reinforcement, and the Tinder Swindler as a case study in love-bombing and emotional manipulation. They also discuss coercive control in relationships, especially financial control, and how shame prevents victims from reporting.
- •Incel psychology: entitlement, grievance narratives, group reinforcement
- •Internet as accelerant for radicalization and harmful norms
- •Tinder Swindler mechanics: love-bombing, luxury proof, future-faking, crisis asks
- •Fraud works by telling people what they want to believe; shame silences victims
- •Coercive control: financial domination, jealousy, and relationship manipulation
- 50:01 – 56:28
Jealousy and monogamy: red flags, communication, and nontraditional structures
Shaw offers a provocative view: chronic jealousy is often about insecurity and control rather than love, and can precede intimate partner violence. This expands into a critique of monogamy as a social construct that sets many people up to fail, and a defense of relationship choice and early explicit negotiation.
- •Persistent jealousy framed as insecurity/control and IPV risk marker
- •Jealousy often fueled by uncertainty and poor ‘lie detection’ instincts
- •Cheating prevalence used to question monogamy as default structure
- •Polyamory as an option; emphasis on honest negotiation and consent
- •Healthy relationships require communication; dynamics matter more than labels
- 56:28 – 1:13:44
Bisexuality and identity: myths, measurement tools, and community belonging
Shaw discusses her book ‘Bi’ and the science/history of bisexuality, including the Kinsey scale and the Klein grid’s multidimensional approach. They address stereotypes (it’s a phase; it’s performative), the social pressures that shape identification (especially for men), and mental health impacts tied to isolation from community.
- •Bisexuality as attraction regardless of gender; not ‘attracted to everyone’
- •Common misconceptions: phase, stepping-stone to gay, performative for women
- •Kinsey scale and postwar context; shifting identity patterns over decades
- •Klein Sexual Orientation Grid: past/present/ideal across multiple dimensions
- •Bi people’s elevated risks (self-harm, violence, isolation) linked to stigma and community exclusion
- 1:13:44 – 1:29:18
Kinks, fetishes, and the ‘disinhibition’ function of fantasy
They examine why kinks are often treated as moral defects and mistakenly tied to criminality. Shaw argues fantasies and consensual BDSM are common and often serve psychological release—freedom through structured role-play—while stigma can generate shame spirals and self-villainization.
- •Kink frequently (and wrongly) treated as evidence of bad character
- •BDSM and other fantasies are more common than people assume
- •Consent tools: open conversation, boundaries, safewords
- •Disinhibition hypothesis: bedroom role-play as release from daily constraints
- •Stigma links to broader queer villainization and mental health harms
- 1:29:18 – 1:32:24
Becoming a criminal psychologist: schizophrenia, reality questions, and gallows humor
Shaw traces her path from intending to study art to psychology, shaped by growing up with a father with paranoid schizophrenia and a lifelong fascination with ‘what is real.’ She describes why criminal psychology appealed: applied, procedural, and populated by practitioners who can handle darkness without losing their lives to it.
- •Early pull toward surrealism and ‘messing with reality’
- •Family experience with schizophrenia as a driver of reality-focused inquiry
- •Criminal psychology’s applied/procedural nature and pattern recognition
- •Coping stance: cases as puzzles rather than emotional absorption
- •Field culture: gallows humor as a survival tool
- 1:32:24 – 1:42:26
False memories: how easily narratives shift, and why AI is a ‘false memory machine’
They dive into memory science: autobiographical recall is inherently reconstructive, usually accurate in gist but unreliable in verbatim details. Shaw explains how short, suggestive interactions can quickly alter memory—and warns that generative AI can intensify this, enabling propaganda-scale gaslighting and personal narrative drift.
- •False memories as normal features, not bugs; ‘how false’ not ‘if false’
- •Gist vs verbatim: detail demands in court exceed human design
- •Memory thieves and social contagion: adopting others’ stories as your own
- •AI confabulation parallels human confabulation; interaction can distort both sides
- •Defense: contemporaneous notes/records; don’t rely on confidence as truth marker
- 1:42:26 – 2:02:13
Implanting a crime memory: Shaw’s study, methods, ethics, and replication debates
Shaw details her landmark study implanting false memories of committing crimes using leading questions, imagination exercises, and social reinforcement. They discuss disputes about what counts as a ‘false belief’ vs a ‘false memory,’ why the key contribution is demonstrating possibility, and how newer work uses AI-generated media to increase plausibility.
- •Study goal: show it’s possible to believe/confess to a crime that never happened
- •Protocol: true-memory rapport + suggestive interviewing + imagination exercise
- •Reinforcement and participant-generated details woven from real-life fragments
- •Ethics constraints and why the team stopped early after high success
- •Follow-on research: AI video/image manipulation increases belief; replication efforts underway
- 2:02:13 – 2:18:18
Cognitive restructuring, attention as memory’s glue, and aphantasia surprises
They explore constructive uses of memory malleability: cognitive restructuring can shift emotional meaning without needing factual certainty, supporting resilience. They discuss practical pitfalls (outsourcing attention to phones) and individual differences in mental imagery, including Shaw’s aphantasia and how that affects mnemonic strategies.
- •State-dependent memory: emotions cue congruent recollections (sad → sad)
- •Cognitive restructuring: reframe negatives into learning and growth
- •Attention as the bridge between experience and later recall
- •Training memory with varied tasks; limits of single-activity ‘brain games’
- •Aphantasia: no mental imagery; implications for memory palaces and mnemonic devices
- 2:18:18 – 2:42:06
Green Crime: the psychology of environmental criminals and the role of heroes and tech
Shaw introduces her book ‘Green Crime,’ applying criminal psychology to environmental destruction—from Dieselgate to poaching networks. They examine how conformity, market pressure, and organizational cover-ups enable large-scale harm, and end on hope: enforcement ecosystems, whistleblowers, and better tech—like her ‘Spot’ tool—can operationalize best practices and accountability.
- •Environmental crime as crimes against shared planetary ‘home’
- •Dieselgate as case study: engineered deception, health impacts, prolonged cover-up
- •Multi-level crime structures: bosses, middlemen, ground actors, financiers, enablers
- •Conformity and normalization inside organizations; whistleblowers as heroes
- •Spot: chatbot-administered cognitive interview for compliant reporting; broader promise of tech if guided by social science
