We often come across interesting posts on social media platforms such as Instagram and TikTok. What you see well in an inverted photo, but quite calm when you turn it right different and scary looking faces You may have come across these posts as well.

The main reason we normally see these faces is; Thatcher effect. So how does this illusion come about? an abnormal face ensures that we perceive well? In today’s article, we’ll look at how these faces were created and how they first appeared.

Contrary to popular belief, the Thatcher illusion is not something new.

This illusion, first ‘developed’ in 1980, was actually the result of an academic study. This effect, revealed by Peter Thompson and his team at the University of York, that our brain puts all the pieces together accepted as the greatest proof.

The Thatcher effect is named after that period. From Margaret Thatcher, British Prime Minister to take. This is because the first photo the effect was tested on was of Margaret Thatcher. Today, however, we see this effect almost everywhere, in various photos.

So why does our brain see these faces as normal?

The nerves that cause this in our brains have not yet been fully explored. After many years of research, this situation is in our brains. from psychological cognitive modules thought originated.

In other words, our brain perceives these images separately and then like a normal face It makes us perceive. In fact, we can see a similar effect when our brain automatically finishes a sentence written in missing letters. Of course, this situation works somewhat differently under the Thatcher effect.

Creating an image with the Thatcher effect is quite easy.

The steps to create an image with this effect are quite simple. In fact, if you look closely, you can clearly understand the difference in the above images. What we need is very simple; a human face.

To replace the human photo we have with this effect, we only have turning the eyes and mouth part upside down suffices. “Why don’t we turn the nose or ears inside out?” If you ask; The sense that this is an inverted image will disappear if we turn the nose or ears upside down and our brain will recognize that there is an abnormality. However, when the other organs are straight, the inverse of the eyes and mouth is automatically corrected by our brain.
