Episode notes
Mind Immunity As A Research Lens
- Andy Norman reframes epistemology through immunology to explain why some people are more susceptible to bad ideas.
- Mental immunity highlights habits, dispositions, and social factors beyond mere skills.
Evaluate Ideas By Evidence And Effects
- Ideas have upstream (evidence) and downstream (behavioral) properties that both matter when judging them.
- Some ideas are harmful because they reliably cause dehumanization or social harm regardless of evidential debates.
Inoculate Against Techniques Not Just Claims
- Teach technique-based inoculation that targets common manipulation patterns instead of chasing every false claim.
- Focus instruction on broad classes (e.g., conspiracy mechanics) so learners detect whole families of sketchy ideas.
