Why Patients Say ‘No’ When They Mean ‘Yes’ — And How It Puts Dental Care at Risk
Accurate medical histories are essential for patient safety, yet online forms can unintentionally trigger a psychological “no set” — a pattern where repeated “no” answers lead to automatic, inaccurate responses. Grounded in Robert Cialdini’s principle of Commitment and Consistency, the “yes set” and “no set” explain why patients may omit vital information without realising it. In dentistry, the solution lies in using pattern interrupts, open questions, and face-to-face conversations to ensure accuracy, build trust, and protect both patient wellbeing and your professional reputation.
