What you are talking about is actually "first impression". The so-called first impression is the first impression about the other person that you get in the process of interacting with a stranger. The first impression is not always correct, but it is always the most vivid and strongest, and determines the course of future interactions between the two parties. The first impression is mainly based on the other person's expression, posture, body, appearance and clothing. The first impression is very common in daily life. This first impression is often the basis for future interactions. The "stereotype effect" is closely related to the first impression. The first impression is often the basis for the stereotype effect, and the stereotype effect is often the deepening and broadening of the first impression. In social practice, there are many examples at home and abroad where first impressions lead to mistakes in hiring people. Therefore, managers should not only pay attention to the first impression, but also try to avoid errors in understanding and employment caused by the first impression. You said this famous saying that if you don't like someone, it's because you don't have high quality. I think it makes sense, but it's not entirely correct. It's just a family statement and can be used as a reference, but it's not a motto.
