Commenting on a viral hiding-in-plain-sight clip, aakashgupta cites vision science: flashing photos for just 20ms, researchers found the brain flags the presence of something alive within 150ms — faster than a blink, with no focused attention required. The detector keys on outline over color or texture, so leafy costumes still fail: head-and-shoulders contours get scanned first. Evolution tuned it paranoid because missing a hidden enemy was fatal, explaining why humans are nearly impossible to hide from.
