Is a person born a genius or can genius be learned?

The man in the picture is László Polgár, a Hungarian chess teacher and professor of psychology. This man was convinced that a genius is not born a genius, and that with training anyone in the world can become a genius. To prove his theory, he conducted an experiment on... His three daughters: “Susan, Sofia, and Judit.” Polgar wrote famous books about the game of chess, such as the chess book “5334.” He is also considered one of the pioneers of theories of raising children. He believes that “geniuses are made, not born.”The man was in fact an expert in chess to the point that he knew how to convey information to his daughters and how to train them accurately, and over time the girls grew up and became the strangest chess family, the Polgár family, the marvel of the game of chess in all of modern history and Olympic champions, occupying the first positions in the world, and from the age of 4 For years, he began teaching them chess, its rules and strategies. *Judit is considered the strongest female chess player in history, and is considered one of the world's geniuses with an IQ of 170! Her sister, Susan, was awarded the title of Grand Master, and the other, Sophia, was awarded the title of International Chess Master. Thus, he actually succeeded and proved scientifically and practically that anyone can be trained in any field to become a genius if he is provided with the appropriate environment, training, and good, continuous education. This experience is considered the most successful and best educational experience in human history. Polgar's experience with his daughters was described as "one of the most amazing experiences."
