Why 90% of people write with their right hand?
Surveys conducted around the world show that about 90% of people write with their right hand. This habit is not limited to writing, but is also evident in most daily activities. According to scientists, it has its roots in the functioning of our brain. The human brain is divided into two parts, the left side controls the right side of the body and the right side controls the left side.
Brain energy is the key to management
When a person learns, reads or writes a language, the left side of the brain is more active. This side directs the right hand. The brain tries to maximize performance with minimum energy expenditure. Writing with the right hand is a more direct and energy-efficient route to the brain. So most of the people unconsciously get right handed.
What if you write with your left hand?
Scientifically, if a person writes with his left hand, the brain first has to transfer language-related signals from one part of the brain to another. This process is longer and more energy-consuming. So the brain naturally prefers the right hand and humans develop this skill from childhood.
Then why are 10 percent of people left-handed?
Does DNA also play a role?
Genetics are also believed to play an important role in being left-handed or right-handed. According to a 2012 study conducted in the United States, if both parents are right-handed, the child has about a 9 percent chance of being left-handed. If one of the parents is left-handed, that chance increases to 19 percent. If both parents are left-handed, the child has about a 26 percent chance of being left-handed.
Influence of society and habits
For a long time, writing with the left hand has been considered wrong in many cultures. Children were forced to write with their right hand. Despite this, the number of left-handed people around the world remains roughly the same, proving that it is not just a habit, but a deep connection of the brain and DNA.
