credence

A graded degree-of-belief in the closed interval [0,1], attached to a DoxasticState. Non-functional: an agent's credence may be reported by multiple sources or updated over time, and those reports coexist (Principle 9). Distinct from gmeow:confidence (our certainty about a statement, in the provenance/statement layer) and from claimModality (qualitative standpoint belief value on the linked StandpointClaim).

Structure

Property shape: datatype property; gmeow:DoxasticState -> xsd:decimal

Practical Pattern
