Just as we struggle to distinguish between Chinese, Japanese or Koreans, they also struggle to distinguish us. Cross race effect We experience this situation, which is called, more when we try to distinguish between ethnic origins that are less similar to our own.
Except for Far East blacks too so that we can compare them. Turks, on the other hand, are not easy to distinguish from other ethnic origins such as Arabs, Armenians, Georgians and Greeks.
A scientific study has also been done on this.

scientists at Northwestern University, 18 white female students were shown pictures of the faces of white, black, Hispanic, and East and South Asian men. They were then shown pictures of the same faces and of new people and were asked to indicate whether they had seen each before.
Participants wore an elastic electroencephalography (EEG) hood with 59 electrodes so that their brain’s electrical activity could be recorded during the experiment. Researchers associated with the event They focused on neural responses. As expected, participants recognized faces of the same ethnicity more accurately.
This is because we have more experience with members of our own ethnicity.

The facial recognition function in our brain can give errors with different ethnicities that are somewhat similar to us. Because the people around us already have similar features such as dark skin, brown eyes, auburn hair, so the functions in our brain are different. thanks to the details accustomed to distinguishing faces. The shape of the nose, chin, eyebrows becomes more decisive in facial recognition. The brain synthesizes these details and enables facial recognition.
When different ethnicities come into play we are not used to that Striking features such as black skin and slanted eyes draw the attention of the brain and other details of those people are hardly remembered. Due to these characteristics, it is possible to recognize them easily. Therefore, when we see another person with black skin or slanted eyes, we think they are similar because they fit the pattern we have in mind.
The Far East do not have such a problem among themselves.

Because crooked eyes are not decisive for them anyway, their brains work to recognize different details and they have no difficulty distinguishing it from their own ethnicity. In addition to the eyes, features such as fair skin, straight and black hair make our work difficult.
If you live in a Far Eastern country for a while or watch Far Eastern movies regularly, your brain will improve itself by focusing on details when discerning the faces of people of this ethnicity.
This is not a disadvantage, it is an advantage within the group. evolutionary adaptation. Discussions on this topic are ongoing and explored in the context of human evolution and psychology.
Finally; We would like to remind you that it would be obnoxious, even racist, to make a joke out of this.
