Episode notes
Psychopathy Is A Scientific Tool
- "Psychopath" is not a courtroom diagnosis but a research tool with checklist criteria.
- High psychopathy traits predict risk but many with them live nonviolent, functioning lives.
Empathy Isn't The Only Brake On Harm
- Lack of empathy makes antisocial behaviour easier but socialization can teach rules.
- Julia Shaw notes some people with low empathy choose pro-social behaviour nonetheless.
Intrusive Thoughts Versus Impulses
- Intrusive harmful thoughts are common and differ from acting by impulse control.
- Shaw suggests fantasies can serve as internal rehearsal that prevents real behaviour.
