Why are some people always used to judging people by their appearances?

This is actually a famous "halo effect" in psychology, which means that a certain positive feature of a person can lead others to look at this person with new eyes, and physical charm is such a feature. We will automatically add some positive characteristics to good-looking people, such as talent, kindness, honesty and intelligence. When we make these judgments, we don't realize the role of physical attraction. This effect is very common in daily life. For example, a study on federal elections in Canada found that attractive candidates received two and a half times as many votes as unattractive candidates. When recruiting, whether the candidate can get a job and whether the dress is appropriate is more important than the job qualifications.
