Why do most people say that left-handed people are smart?

People say that left-handed people are smart because some old people say so, and then spread it around, and such a statement has gradually formed? Left-handed people are smarter than right-handed people, but this is not the case. This is an unscientific statement, a rumor and unreliable. First of all, left-handed people are used to using their left hands, but most people are used to using their right hands, so we rarely see left-handed, and left-handed people show great differences with right-handed people in doing things, especially in painting, writing and reading, so some parents force their children to use their right hands in order to change their children. I remember one of my classmates used to use his left hand in primary school, and finally the teacher slowly changed him. It's not that being left-handed is bad. It's just that it's really inconvenient to do things with your left hand. It's better to do things with your right hand. In the initial stage of writing, the right hand is obviously faster and better than the left hand, on the same basis. It's not that left-handed people are not good, just like left-handed people often think of shaped images in their minds before writing or drawing. Many left-handed people will try their best to reassemble the bits and pieces they can't remember into a page of pictures and then remember them with pictures; Like the father of modern architecture? Bruley, in the14th century, was able to put forward digital graphics to explain how to build Florence Dome Cathedral; So some people think that it is this ability that explains why many left-handed people are engaged in matters involving space and art; Also, left-handed people seem to be excellent in quick response and correct spatial judgment. Those who tend to be left-handed, left-footed and left-eyed will be more flexible and strong, especially in some sports, such as tennis, football and golf, such as tennis celebrities Nara Dinova, Connors and mcenroe. Therefore, it cannot be said that left-handed people are smarter than right-handed people. We can only say that a natural left-handed person may be better than a right-handed person in some aspects, but it also depends on that person's own efforts, not that he must be smart because he is left-handed.
