Risk Terminology & Statistical Literacy
Understand the critical difference between relative risk changes and actual, absolute baseline probabilities.
Biological Mechanism & Scientific Context
A headline claiming a genetic variant "doubles your risk" (200% relative risk) sounds alarming, but if the baseline absolute risk is 1 in 10,000, doubling it only increases it to 2 in 10,000 (0.02%). Understanding this distinction protects readers from health anxiety and commercial fear-mongering.
