Our brains have developed incredible tactics and coping mechanisms to help us make sense of the complex world around us. But some parts of our highly adaptive minds aren’t perfect and can be exposed through carefully crafted illusions.
These squares are actually the same exact color. Hold your finger over the boundary between the two shapes and see them change.
The Cornsweet illusion exploits the brain’s lateral inhibition, which creates more contrast between the two objects when they have different colored edges.
Cross your eyes and you should be able to see a familiar face.
Stare at this lady’s nose for 10 seconds, then blink rapidly while looking at a light surface. Her face will appear in full color.
These cars look like they’re different sizes…
but in reality they’re all the same.
The Ponzo illusion works because our brain judges an object’s size based its perceived distance. The 3rd car seems further away, so it looks much bigger.
These dots seem to change color and orbit the center. But focus your eyes on a single dot – there’s no rotating or color change at all.
Similarly, stare at the cross in the center and watch the blank spot.
This park in Paris looks like it has a giant 3D globe…
But it’s actually completely flat.
Which orange circle looks bigger?
Surprisingly, they’re the same size.
The Ebbinghaus illusion exploits our perception of relative size. When an object is surrounded by larger objects, it seems far smaller than it actually is.
Stare at the yellow dot. Then, move your head closer to the screen and the pink rings will rotate.
The Pinna-Brelstaff illusion occurs because of flaws in peripheral vision.
You won’t believe it, but the squares marked ‘A’ and ‘B’ are actually the exact same shade of grey.
This replica proves it…
Our brains automatically adjusts color based on surrounding shadows. Since B is in the shade of the green cylinder, but is still the same color as A, the brain believes that it’s a lighter shade of grey.
