The Media Has A Probability Problem The media's demand for certainty - and its lack of statistical rigor - is a bad match for our complex world.

News stories regarding the latest in the world of medicine are often popular. After all, most people are interested in their own health and that of their family and friends. But sometimes reports can be confusing. For example, one minute coffee seems good for you, and the next it's bad for your health. And remember when 150 health experts from around the world called for the 2016 Rio Olympic Games to be cancelled or postponed because of the Zika virus? This call was swiftly opposed by both the World Health Organisation (WHO) and the Centers for Disease Control and Prevention (CDC). Sometimes these contradictions reflect differences of opinion in the scientific community, and different approaches to research. These are a normal part of the scientific process. But in other instances, health news misinforms because of the way some journalists interpret and report research findings.
