The image “looks far more shocking than it actually is,” which is why it spread so quickly online. Viewers felt “a brief jolt of confusion” before realizing they had misread it. Scientists say the illusion works not because of the picture, but “because of you.”

We don’t see the world clearly — the brain creates “a fast, approximate reconstruction” based on past experience. It prioritizes speed over detail, jumping to the most familiar pattern. Even people who think they “never get tricked by illusions” are fooled because the brain takes shortcuts.

In lab tests, the image exposed clues about stress, fatigue, and thinking speed. Some saw something ordinary, others saw something plausible but wrong, and a small group saw something “entirely unrelated.” What you notice first reflects your internal state, not the image.

Your brain relies on prediction, not complete information. The image was designed to resemble something familiar enough to trigger an automatic assumption, causing most people to misidentify it instantly. As researchers put it, “the image didn’t create that mistake. Your brain did.”

Illusions reveal the hidden systems shaping perception — shortcuts, assumptions, and blind spots. Culture and environment also influence how we interpret ambiguous images. The illusion spread because people wanted to compare reactions and understand why they were fooled. It highlights a simple truth: “we don’t see reality. We see our brain’s interpretation of reality.”
