Whole‑number framing improves probability reasoning

Rob Kurzban notes that people — from high‑school students to doctors — reason better about conditional probabilities when information is presented as whole counts (e.g., '3 out of 10') rather than abstract percentages. This suggests a small but actionable communication fix for teaching statistics, clinical decision‑making, and public risk messaging. — If adopted widely, switching to whole‑number framing could improve public understanding of risk, reduce medical decision errors, and change how policymakers and journalists present probabilistic information.
