Does chocolate win Nobel Prizes?
Chocolate consumption, cognitive function, and Nobel laureates
Countries that eat more chocolate have more Nobel Prize winners. Correlation: very strong. Causation: probably not.
A cardiologist plotted chocolate consumption per person against Nobel laureates per person for 23 countries. The correlation was startlingly strong, with Switzerland on top.
It is a tongue-in-cheek lesson in why correlation doesn’t equal causation. The author also admitted he eats chocolate daily.
Eat chocolate. Possibly not for the Nobel.
