A well-built tool delivers a high-value answer for modest, well-signposted effort, raising expected utility. Abandonment can happen within seconds when perceived value drops.\n\n**Source:** nngroup.com engagement / form-design literature.\n\n**Confidence:** Industry-consensus (NN/g is an independent UX authority — no portal/calculator vendor incentive).\n\n**Why this matters for Candid:** Operationalises the [[kivetz-2006-goal-gradient-coffee-stamps]] mechanism in interface terms. A tool that fails the value-minus-cost test is abandoned regardless of how well its psychology is grounded.
