People who know psychology are not that good. In fact, people with medical knowledge will also encounter many psychological problems. It doesn't mean that they don't have psychological problems, so people who understand psychology are not that powerful. It just means that they have professional qualities and some professional knowledge, which can help others out of some difficulties or psychological problems, but it doesn't mean that they can solve all problems, so people who understand psychology are not as powerful as they think. Besides, they are not the kind of people who can guess your thoughts. They just said that they would judge you or enlighten you according to some practical applications. That's it at best. In fact, there are no magical psychologists, and you don't have to think they are too magical and powerful. They are also ordinary people.
