Episode notes
Dark Traits Are Continuous
- The Dark Tetrad traits (psychopathy, narcissism, Machiavellianism, sadism) exist on continuous scales rather than as binary labels.
- Scoring high on multiple traits raises harm risk, but most people are subclinical and mixed across traits.
Reject Binary 'Evil' Labels
- Calling people "evil" ends conversations and prevents understanding root causes of harmful acts.
- Empathizing with offenders helps reveal psychological and social levers to prevent future harm.
Group Dynamics Enable Atrocities
- Dehumanization plus de-individuation (us-vs-them group identity) enable large-scale violence like war.
- These social processes create a cloak of moral justification for atrocities.
