So, Drew says, we need to think carefully about the instructions we give to professional searchers like radiologists or people looking for terrorist activity, because what we tell them to look for will in part determine what they see and don't see.German-born Dutch Western gorilla (1996–2023)īokito (14 March 1996 – 4 April 2023) was a male western gorilla born in captivity that lived most of his life in Diergaarde Blijdorp zoo in Rotterdam, the Netherlands. ![]() In other words, what we're thinking about - what we're focused on - filters the world around us so aggressively that it literally shapes what we see. "They look right at it, but because they're not looking for a gorilla, they don't see that it's a gorilla," Drew says. They were looking for cancer nodules, not gorillas. ![]() Instead, the problem was in the way their brains had framed what they were doing. This wasn't because the eyes of the radiologists didn't happen to fall on the large, angry gorilla. He wanted to see if they would notice a gorilla the size of a matchbook glaring angrily at them from inside the slide.īut they didn't: 83 percent of the radiologists missed it, Drew says. He then asked a bunch of radiologists to review the slides of lungs for cancerous nodules. He took a picture of a man in a gorilla suit shaking his fist, and he superimposed that image on a series of slides that radiologists typically look at when they're searching for cancer. "You might expect that because they're experts, they would notice if something unusual was there," he says. That effect is called "inattentional blindness" - which brings us back to the expert lookers, the radiologists.ĭrew wondered if somehow being so well-trained in searching would make them immune to missing large, hairy gorillas. So, often, they literally can't see even a huge, hairy gorilla that appears directly in front of them. This is because when you ask someone to perform a challenging task, without realizing it, their attention narrows and blocks out other things. "There's a gorilla on the screen - of course you're going to see it! But 50 percent of people miss the gorilla." The kids keep playing, and then the video ends and a series of questions appear, including: "Did you see the gorilla?" He stops momentarily in the center of the circle, looks straight ahead, beats his chest, and then casually strolls off the screen. Then, about a half-minute into the video, a large man in a gorilla suit walks on screen, directly to the middle of the circle of kids. Because the players are constantly moving around, viewers really have to concentrate to count the throws. Before it begins, viewers are told their responsibility is to do one thing and one thing only: count how many times the players wearing white pass the ball to each other. In that groundbreaking study, research subjects are shown a video of two teams of kids - one team wears white the other wears black - passing two basketballs back and forth between players as they dodge and weave around each other. Because of his line of work, he was naturally familiar with one of the most famous studies in the field of attention research, the Invisible Gorilla study. YouTubeīut radiologists still sometimes fail to see important things, and Drew wanted to understand more. ![]() By focusing their attention on the ball, they tend to not notice when a guy in a gorilla suit shows up. In the Invisible Gorilla study, subjects have to count how many times the people in white shirts pass the basketball.
