Why Human left brain is more developed than right brain?

Most people's left brain is more developed. This is because humans rely on the right side of the body when exercising, and their thinking activities are also dominated by logical thinking. For example, when writing, you basically use your right hand. For complicated things, the right hand is usually the main one. Use the right hand more often, which in turn strengthens the left brain function.

Some people are born left-handed. According to research, it may be related to the stimulation of some substances during the fetal period. Normally people are always right-handed.

School education is usually based on knowledge courses, supplemented by art courses. Knowledge courses are generally based on the left brain, while art courses use the right brain. In particular, domestic school education is score-oriented education. For the sake of scores, art courses can be cancelled at will, which is not conducive to the balanced development of the left and right brains.
