Trustworthiness has multiple grounds that vary across different people

Evidence

I trust some people because I know they have a stake in our ongoing relationships, others because I know they are morally committed to fulfilling my trust with respect to certain things, and others still because I think their character dictates their trustworthiness. A few have an especially strong stake in our ongoing relationships because they are close friends, and a very few because they love me. — Russell Hardin, Trust and Trustworthiness, 880

Categorization

• DEFINE: Distinguishes interest-based, moral-commitment-based, and character-based grounds of trustworthiness — a conceptual taxonomy central to Hardin’s framework.
• XREF: The interest-based ground echoes the reader’s Hardin-vs-Luhmann integration: encapsulated interest requires the observable constraints of ongoing relationships.
