Do we have an unhealthy appetite for pie (charts)?

Blandine Moulin ( à gauche ) et Nicole Vadot ont manié humour et rigueur scientifique. Murielle Geber/EPFL - Summer series - Semester project. Three university students, as part of their critical data studies class, wrote a light-hearted yet instructive comic strip about perception biases in the presentation of data. The story starts with two artisan cheesemakers who are hauling their product to market when their carts - one horse-drawn, the other ox-drawn - collide. Raymonde, a 70-year-old woman who witnesses the collision, complains that accidents involving horse-drawn carts, unlike ox-drawn ones, are becoming more frequent. She goes on to back up her premise with pie charts showing the trend is getting worse every year. But Hugues, another bystander from the same age bracket, isn't so easily convinced.
