Episode notes
Trust Is Vulnerability Not Mere Behavior
- Trust is a willingness to be vulnerable when real risk exists rather than just behaving as if you trust.
- Safeguards can reduce risk but often lower perceived trust because cooperation is attributed to the guardrails.
Two Core Dimensions Drive Trust
- Trust judgments rest mainly on competence and integrity, with benevolence highly correlated with integrity.
- We weigh positive and negative information asymmetrically across these two dimensions.
Why Some Violations Never Fade
- Competence violations are forgiven more readily because positive signals later are seen as diagnostic.
- Integrity violations stick: a single negative act outweighs later positive signals.
