How common social anxiety is, we need big data to give the answer, and we cannot jump to conclusions. Don't just guess.
I can only calculate and draw conclusions on this issue based on the situation around me. Many people suffer from social phobia anxiety. I mainly contact teachers, students, parents, business people... there are very few people who are willing to communicate.
What everyone shows is that they are not willing to go out and communicate with others. After get off work, they basically go home and do activities at home by themselves, reading, surfing the Internet, watching TV... and even not going to parties. The leadership must be removed.
There are also some delivery boys who usually go to Internet cafes around the community to surf the Internet and are not willing to socialize. Outstanding performance, the most prosperous business is the Internet cafe.
Why? It’s avoidance, social phobia, and anxiety.
What to do? We also need to relax our mentality. Although it is not good to not socialize, it also has advantages. There are also merits. Everyone can do their own thing with peace of mind. Especially technical staff and teachers, they really don’t have to socialize. Officials are also much cleaner and can no longer see drinking establishments. This is progress.
