Note(s): Values are means on a 0–10 scale from 9 complete responses after excluding 2 incomplete records from the raw Google Forms CSV. The 15 vignettes and dimension wording are taken from question.pdf. D1 asks how much generative AI can technically assist the task assuming no legal, liability, or sign-off restrictions. D2 asks how much actual sign-off, liability, compliance, and audit-traceability requirements limit use of AI-generated outputs. A response was retained only when all 15 D1/D2 paired ratings were present and each task-level professional-judgement confirmation was marked yes. The calibration-only adjusted score is computed at respondent-task level as AI Help $\times (1 - Barriers / 10)$ and then averaged. It is a descriptive calibration summary, not a validated exposure measure
