Decision Confidence

A reframing of accessibility as whether a user can judge product suitability, transaction risk, and information trustworthiness well enough to act independently — introduced by Ryskeldiev et al. (2026) in the context of blind and low-vision e-commerce. Where WCAG conformance asks whether code-level barriers are absent, decision confidence asks whether the user actually has enough information (and verifiable information) to buy, sell, accept, reject, or commit. Decision confidence foregrounds experiential outcomes — time to confidence, reliance on sighted help, cart abandonment — over technical audits. The concept generalises to other high-stakes accessibility domains such as healthcare portals, legal forms, and voting, where compliant interfaces can still leave disabled users unable to make meaningful choices.
