1 in 10 or 10 in 100? | Why the Same Risk Sounds Different to Your Patient
Same drug, same side effect, the same number written two ways. Across experiments, people given the one-in-something wording tended to rate the risk higher and to overestimate the actual figure by more. Two moves that keep the number accurate for the patient: the same denominator when you compare a benefit with a harm, and a prepared picture of the proportion when the decision matters.
