[There has been much talk in recent days of slowing U.S. artificial intelligence research. China immediately announced that it would have no part of the “fearmongering” and would not slow down at all. But they are far from the only active enemy employing AI against us. — Rod Martin]
In 1999, two psychologists conducted a study in which test subjects counted how many times a basketball was passed among individuals wearing white shirts. The passing was not tricky to see. The action was not particularly fast. On its surface, it was a simple task.
Yet half of the participants missed the gorilla.
Midway through the video, a student in a full gorilla costume walked into the center of the court, turned to face the camera, thumped its chest, and strolled off-screen.
The viewers’ eyes swept over the primate. Still, their brains, entirely consumed by the mental arithmetic of pass-counting, filtered out the visual data.
They missed the obvious because they were preprogrammed to a particular task.
A decade later, researchers ran a similar experiment with board-certified radiologists. These were not novices, but bona fide experts, examining chest CT scans.
These doctors were asked to look for suspicious lung lesions, called nodules, often indicative of cancer. Special software tracked their eye movements so researchers would know exactly where they were looking.
But then, just as in 1999, there was a gorilla.
Embedded in the lung tissue of the final scan was a graphic of a gorilla, 48 times the size of the average cancerous nodule. Of the 24 radiologists in the study, 20, or 83 percent if you are so inclined, failed to see it, despite the eye-tracking software proving they had stared right at it for half a second.
How could they have missed a gorilla in a chest CT scan? When they stared directly at it?
This cognitive glitch, inattentional blindness, is not merely an academic curiosity. It is the ultimate cloak for asymmetric warfare.
