Novel-Perspective Surfacing [2, 3, 5, 8, 12]
A use episode in which an AI system surfaces a perspective on a familiar topic that the user reports not having considered before. The referent is the discovery event of a previously unconsidered viewpoint during interaction.
Operational Definition
EVENT. One occurrence is recorded when (a) an AI output introduces a perspective absent from the user's prior framing of the topic and (b) the user acknowledges it as new to them. The observable markers are a rater-identified perspective shift in the output plus a user confirmation of novelty.
Measurement Schema
Proposed measurement protocol (not yet empirically validated): Two-source corroboration: trained raters code each output for introduction of a perspective not present in the preceding user turns (presence/absence), and users rate each flagged output on a 5-point novelty item ('this viewpoint had not occurred to me'). An instance requires both signals; could be reported as novel-perspective episodes per session. Rater reliability via Cohen's kappa; convergence of rater flag and user rating via phi coefficient.
