The Gorilla You Missed
Original passage © Studio AM, written for Fluency.
In one well-known experiment, viewers watch a short video of two teams passing a basketball and are asked to count the passes made by the team in white. Halfway through, a person in a gorilla suit walks into the middle of the game, faces the camera, beats their chest, and strolls away. About half of the viewers, counting carefully, never see the gorilla at all.
The finding is called inattentional blindness. The eyes work normally and the gorilla lands on the retina; what fails is attention. Attention behaves less like a lamp that lights a whole room and more like a narrow beam that has to be pointed somewhere. Whatever the beam is not on can cross the visual field unrecorded.
Viewers usually refuse to believe the result until they watch the clip a second time. That second reaction matters as much as the first. We are blind to the gaps in our own seeing, which is why a driver can look straight at a motorcycle, report an empty road, and be telling the truth.
