Shattering the myth: Which direction is the ballerina heading - and does that really mean you're smarter?

The optical illusion that drove the network crazy for over a decade, and served as a tool for IQ tests and ways of thinking - was actually a bitter mistake.

Researchers claim that there is no connection between our intelligence and the way we see this ballerina spinning - and it is only our fear of reptiles that has driven us to do so.

In which direction does the ballerina in the picture turn?

The optical illusion that has plagued the world - and you have probably encountered it before - plays with the visual perception of your brain and it seems that the controversy about it, more than a decade since it came into our lives, still stands.

Previous studies have claimed that some of you (and even most of you) will see the ballerina turning clockwise, others against it and those with high IQ will be able to see it rotating every few seconds in a different direction.

The rotating ballerina was used as a tool to test intelligence and diagnose the dominant side of the brain - right or left.

According to the same studies, the one who sees the ballerina moving clockwise - the one who sees the right side of his brain more dominant (which indicates creative thinking) and the one who sees the ballerina moving counterclockwise - is the one whose left side in his brain is more dominant (which indicates On logical thinking).

Now, a new study claims that everyone made a terrible mistake and that the only thing that is true of everything we've told you so far is that most of you will actually see the ballerina move clockwise and not the other way around - but for completely different reasons.

The illusion that plays with your mind

This optical illusion was created by Japanese flash designer Nobuyuki Kaihara in 2003. The rotating figure contains two-dimensional information about a three-dimensional object - so it is difficult to unambiguously determine the direction of its rotation. The brain cannot know the direction of rotation because it lacks details. So he "guesses" the direction and continues to imagine the same direction in order to maintain consistency and logic. Sees as a rotation and not as a pendulum motion.

According to the new study, the reason we tend to see the dancer rotating clockwise does not indicate a more dominant right side - but rather our point of view, which tends to almost always be from above.

In everyday life we ​​are used to being deterred by things that are on the ground - like snakes, spiders or cockroaches - so we are used to examining visual information in a downward view.

Arthur Shapiro and Nico Trujillo, the scientists who analyzed the illusion in question, explained that identifying the direction of rotation is related to our area of ​​the brain dealing with fear, rage and panic.

These two also claim that as long as the brain is not damaged for any reason - anyone can see the ballerina spinning in both directions and that it has nothing to do with our level of intelligence.

Shapiro emphasizes that you do not have to be a genius to see the dancer turn to both sides, "cover everything except her leg that touches the floor," he explains, "stay focused on the leg and the shadow underneath. In it again from above. "

When you imagine yourself under a dancer, she has to turn counterclockwise and when you are supposedly above her, you are supposed to see her turn clockwise.

Shapiro, a professor of computer science at the American University of Washington, D.C.

He added "what we thought until today was just nonsense. There are more complex reasons than our intelligence for the way we see the character go around."

According to him, these types of optical illusions do not reveal information about the depth of the image and therefore our brain has a hard time understanding it.

When the picture is unclear, our brain takes the initiative and fills in the missing information itself.

Adding 3D details to an image can help the brain fill in the missing information and determine the direction of rotation completely.
