The Science Behind Gut Feelings
Intuition is real and measurable, but often misleading
Intuition is a tough thing to study. Even defining it is tricky. It’s not quite an insight, which is when a solution or some other bit of hoped-for knowledge pops into your head. It’s more like a sixth sense or a feeling — an inclination that you can’t really explain but that seems trustworthy.
Some ingenious researchers have found ways to both capture human intuition and also shed light on its inner workings.
For a 2016 study in Nature Scientific Reports, a team of Italian scientists filmed a series of short videos. In each of the videos, an unidentified person grasps a half-full bottle of water with the intention of either drinking from it or pouring its contents into a glass.
Next, the researchers had people watch one-second clips cut from the original videos. Each of the clips ends the moment the unidentified person’s fingers touch the bottle. The people who watched the videos tried to predict whether the person in the video was going to drink from the bottle or pour out its contents. Remarkably, their predictions were accurate far above the level of mere chance. Just by seeing a hand reach for a bottle, they were able to intuit what would happen next.
