The Yamagishis define trust as faith in another’s moral character, not self-interest.

Evidence

For Yamagishi and his colleagues in various experiments on trust, “trust” is defined by its dependence on such characteristics as moral dispositions and commitment to norms rather than on the kinds of reasons implicit in the encapsulated-interest view of trust. Indeed, Toshio Yamagishi and Midori Yamagishi (1994) call the latter merely assurance. — Russell Hardin, Trust and Trustworthiness, 387

Categorization

• DEFINE: Defines the Yamagishi alternative to Hardin’s encapsulated-interest view, and notes they relegate the encapsulated-interest account to mere ‘assurance.’
• XREF: Connects to Luhmann’s familiarity/assurance distinction and to Hardin’s own encapsulated-interest theory as the two competing definitions being integrated.
