Gerd Gigerenzer: How good are you at calculating risk?

How good are you at calculating risk?

A new drug reduces the risk of heart attacks by 40%. Shark attacks are up by a factor of two. Drinking a liter of soda per day doubles your chance of developing cancer. These are all examples of a common way risk is presented in news articles, and can often be misleading. So how can we better evaluate risk? Gerd Gigerenzer explores the difference between relative and absolute risk. [Directed by Visorama, narrated by Addison Anderson].

The way risk is reported often distorts our understanding, making threats or benefits seem bigger than they really are. For example, a new drug may cut heart attack risk by 40%, but in real numbers, that means just four fewer heart attacks in a group of a thousand. News stories favor attention-grabbing relative figures, while the quieter absolute numbers reveal the true scale. Understanding both helps individuals make smarter choices about health, danger, and everyday life.
