Why is it easy for people to remember other people's faces, but it is difficult to remember other people's names?

It is easier for people to remember images, but it is more difficult to remember words, because this is a living habit or memory that we formed when we were very young. Because we left such a deep impression in our childhood, we prefer those graphic memories.

For example, when we were young, we were able to read words through graphics, that is, we used our brain's rapid cognition of graphics to approach the essence of words. For example, we will have a picture of a cross with an apple on it. Our parents will tell us that it is an apple, and then when we see this picture, we will know that it should be called an apple. But when we see the word apple, we may not be able to get the picture of this apple, or we may not be able to remember these two words, so the graphics are more touching.

From the perspective of human evolution, graphics have existed since nature, and there are all kinds of strange graphics in natural life. These things symbolize a certain meaning, and in the depths of our genes, there are all these subconscious manifestations, but words are a man-made thing, which only appeared when human civilization developed to a certain extent. Writing is a fictional concept, which does not exist naturally, just like many things in our real life. For example, some legal concepts, some concepts of traffic lights at night and white night, these are fictional concepts, which do not exist naturally, but are artificially stipulated by us. Therefore, what is artificially prescribed will appear in our brains in the form of secondary memory, which requires secondary memory to remember clearly.

We have a more accurate and clear understanding of graphics, so when we see a person's face, we will have a more obvious impression on this person. That is to say, the next time we see him, you may not remember his name, but you will remember that you have seen him before, because remembering a name means remembering words, while remembering a person's face means remembering graphics, so it is easier to remember a person's face than to remember other people's names.
