The benefits and harms of chess
What specific qualities does chess develop? Let's go.
A responsibility. Chess is an individual game. Literally everything depends on the player himself. How prepared, including psychologically. How he played, withstood the load, how attentive he was. That is complete independence. And she brings up responsibility.
Independence. Speaking of independence. At the chessboard you are one on one with all the challenges, problems, choices. It all depends on you, on your decisions. You won’t ask for a hint, you won’t look at Google. The result of the game is the result of one's own decisions.
Decision making. What even a very young chess player does during a game is the process of constantly choosing the best solution. In theory, the decision-making process is already a program of higher education. And in chess - please, the training of this most important skill in life is already in childhood. Gradually, the decision-making process becomes a skill. It seems that few people will dispute the importance of learning how to make decisions quickly and correctly.

Now a few words about the shortcomings. The word "harm" somehow does not want to be used. It's not very appropriate.
Rather, it is correct to talk about some of the problems that may arise when playing chess. Not even problems, but disadvantages that can be smoothed out.
Lack of physical activity

Chess, of course, is a sedentary game.
However, the energy costs are quite high. Serious, responsible games can take no less energy than a full-fledged cross. There are cases when a chess player lost one and a half to two kilos per game.
However, inactivity is not such a problem, frankly. It is only important to monitor your posture. This is especially important for children. And nothing prevents you from jogging before the game or playing football.
And during the game, it is not forbidden to get up from the table and walk around the tournament hall.
