Does the psychologist know what kind of personality he is when he looks at this person?

I remember a teacher often told us that I am a psychologist, but I am not a fortune teller. I don't know what you are thinking, but I can know what you are thinking through a series of behavioral observations.

Just like the question you just asked, the psychologist will not see your personality at a glance, but will communicate with you, observe your words and deeds and so on. You can get subtle information, such as your attitude and practice in handling things, which can reflect your personality characteristics from the side.

Psychologists are also human beings, but they have accumulated more experience in this field.
