The next sentence for an expert must be accurate.

Commonly used saying: Experts watch the door, laymen watch the excitement——

Interpretation: Experts refer to people who have rich knowledge and experience in a certain thing or job. Taoism, tips and methods of doing things. A layman refers to a person who does not understand or has experience in a certain thing or job. The whole meaning is: insiders look at things by methods and essence, while laymen can only look at things by their appearance and excitement.

Usage: It is often used to say whether a person is an expert or an outsider.

Example Sentences

Example 1 His boxing skills are unusual. Experts can only see the rules, but outsiders can only watch the excitement. According to martial arts experts, his moves don't seem to have many tricks, but they are steady and powerful, showing real kung fu.

Example 2. Young people don’t like to watch this old man’s play, mainly because they can’t understand it. But real theater fans love to watch it. This is what the so-called insiders know how to do, and laymen only watch the excitement.

Psychological explanation

Perception is the human brain’s reflection of the overall objective things that directly act on the sensory organs. There are many stimuli that act on people at the same time, but due to the limitations of information channels, people cannot clearly reflect all the stimuli. They can only reflect those stimuli that are important to them. This is Perceptual selectivity. The stimulus that is clearly reflected is called the object of perception, and the stimulus that is reflected vaguely is the perceptual background. Therefore, for "laymen", "bustling" is the object of perception and "doorway" is the background of perception; while for "experts", it is just the opposite.
