This strange optical illusion is sure to make you look twice.
At first glance, you might not spot anything wrong with the upside-down image of Tesla’s billionaire founder, Elon Musk.
On closer inspection, however, you’ll notice that his facial features aren’t quite right.
Flip the picture upside down and you’ll realize that the South African eyes and mouth are actually right up.
The brain can’t detect small changes when the image is flipped down, but will immediately notice it when it’s flipped 180 degrees.
It’s an illusion that dates back to 1980 when a scientist created what is believed to be the first iteration.
It was presented in a paper by Peter Thompson, of York University, and features a believable image of former UK Prime Minister Margaret Thatcher.
The photo shows her face flipped 180 degrees while her eyes and mouth are inverted.
When upside down she looks normal, while when upright she looks weird.
As a result, the illusion is sometimes referred to as the Thatcher Effect.
Many similar images have been cropped in the decades since, each revealing a great deal about how the brain processes images.
Faces seem to be unique to us even though they are all quite similar, and that has to do with our cognitive processes.
It is thought that we develop specific processes to distinguish between faces based on the configuration of features – such as eyes, nose and mouth – such as details of the facial features themselves. .
As such, we can recognize someone’s face when it’s face down even if their eyes and nose are turned upside down.
There is evidence that monkeys and chimpanzees experience the Thatcher effect.
This suggests that our ability to process faces evolved from a common ancestor about 30 million years ago.
