Your car breaks down. Must be because you skipped an oil change last month. Or your favorite team loses. Well, that was because of a bad call by a corrupt referee. In reality, many events involve multiple contributing factors. But we tend to gravitate toward single causes. 

In this episode of Choiceology with Katy Milkman, we look at our desire to explain things simply, even when the truth may be more complex.

Why is my friend late? How does nuclear fission work? What occurs when I sneeze? We all need to understand why certain things happen. Some researchers think the drive to explain the world is a basic human impulse, similar to thirst or hunger. This week on Hidden Brain, we begin a three part series on why we tell stories. Psychologist Tania Lombrozo discusses how explanations can lead to discovery, delight, and disaster.

There are few human impulses more primal than the desire for explanations. We have expectations concerning what happens, and when what we experience differs from those expectations, we want to know the reason why. There are obvious philosophy questions here: What is an explanation? Do explanations bottom out, or go forever? But there are also psychology questions: What precisely is it that we seek when we demand an explanation? What makes us satisfied with one? Tania Lombrozo is a psychologist who is also conversant with the philosophical side of things. She offers some pretty convincing explanations for why we value explanation so highly.
