The debate between the left and the right

Today, it seems incredible that people who prefer to use their left hands are still regarded as vulnerable groups. In order to be fair, the media increasingly use the word "left-handed" instead of the discriminatory "left-handed". Relatively speaking, most people who are used to using their right hands are called "right-handed".

The social balance has been tilted, and left-handers no longer need to deliberately hide their physiological instincts. Their social orientation has changed from an original alien to a "special minority", and the latter word has undoubtedly brought more appreciation and worship. When a girl says to you, "God, you are left-handed!" At that time, she subconsciously regarded you as a handsome, intelligent, artistic and unusual man.

Left-handers should be proud, because they are not only special, but also seem to be more likely to perform well-today's women prefer their children to be left-handed because they are superior in art, science and politics, such as Franklin, Churchill and Greta? Jiabao-in this way, their chances of becoming a celebrity mother are much greater than their chances of marrying a celebrity.

We already know that because the right hand is controlled by the left hemisphere and the left hand is controlled by the right hemisphere, left-handed people should have a more developed right brain than ordinary people and have greater advantages in perceptual thinking and agility-but even Einstein himself can't answer the question satisfactorily, that is, "Why is left-handed?"

Some people say that the content of male sex hormones determines whether the left hand plays a leading role, because there are more left-handed people than women in real life; It is also said that left-handedness is caused by brain injury at birth, because children with infantile encephalitis have a 70% chance of becoming left-handed. But these ideas can't convince everyone. Imagine what would happen if a right-handed woman was injected with a lot of androgen. She may grow a beard, but she will never be left-handed.

The gene theory in genetics seems to be the closest explanation to the truth, because we can already be sure that the phenomenon of left-handedness is innate. Scientists who agree with this argument assume that there is a gene in DNA that determines whether people are accustomed to using their left or right hands-otherwise, it cannot explain why the British royal family has been left-handed. However, so far, the medical community is still trying to find this gene, that is, it is only a hypothesis or inference.

be in a dilemma

The present scenery can't cover up the bitter days of the left-handed. For thousands of years, they have been regarded as unclean groups, enjoying the same treatment as leprosy, mental illness and slaves. Have you ever seen those portraits of demons with arrows, tails and pointed ears? In ancient murals, left-handed people were painted like this. In traditional Judaism and Catholicism, the left hand is simply equated with the devil. You may have read Harry Potter and learned that wizards have to use wands to use magic, but that omnipotent booklet didn't tell you that in ancient England, when witches were killed, many left-handers were burned alive as witches.

In modern times, the situation of left-handed people is not much better, although they have been upgraded from "inaccessible" human beings to "pathetic" human beings. The word "left-handed" comes from the Latin manus with the suffix cus, which means physical defect. Until 192 1, a psychiatric paper still regarded left-handedness as a sign of mental retardation.

Dramatic changes have only occurred in the last twenty or thirty years. Scientists have found that the corpus callosum of left-handed people is more developed than that of right-handed, that is, the brain wave transmission speed is faster and the central nervous system is more active. So the object that was scolded and neglected became a symbol of genius, and those who succeeded because of their left hand received unprecedented praise. Even when the scandal of Clinton's affair came out, many American media secretly praised: You see, our left-handed president not only has outstanding political achievements, but also has such a romantic love life!

However, society still mainly serves right-handed, and orthodox education and worried parents have been tirelessly trying to correct left-handed children. From an early age, they used scolding and sticks to order their children to switch to their right hands. The Thorn Birds once described in detail the discrimination suffered by left-handed children: Young Maggie was severely punished by her mother, including confinement, including tying her left hand to the clipboard.

Occasionally, a few enlightened parents let themselves go, but when their children grow up, they will be very annoyed to find out how inconvenient it is for people who are used to using their left hands in life, such as always bumping into others' right hands, such as driving is often dangerous. Most people in the world are right-handed, so even Bill Gates, who has deep pockets, can only default to the mouse operation of WINDOWS operating system as a "right-handed habit" without any choice, even though he is an out-and-out left-handed.

Left ethnic group

However, they will also feel difficult and powerless, and it is not easy to go against their physiological instinct.

"I think that even if we want to correct children who love to use their left hands, the best way is to use psychological guidance and never use violence. Induction is the best method. And you know, some people may never change. "

However, this situation has been improved in the development of modern education. Sociologists and educators have taken on the task of teaching children to use their left and right hands at the same speed, that is, to train both left-handed and right-handed people from the day after tomorrow. This will not only enable children to exercise their left and right brains at the same time, improve their abilities in all aspects, but also fundamentally eliminate discrimination against left-handers. Perhaps this method has little effect on adults, but at least we can expect that in the next fifteen years, a new generation has grown up and the name "left-handed" will gradually disappear.

In addition, people are more keen to train left-handed players, such as tennis players, artists or social activists. In these fields, they are more likely to succeed, get higher psychological satisfaction and adapt to social life.

Economic interests determine everything. In today's society, no one will ignore the huge consumer group of left-handed people because of prejudice.

Even in China, where there are few left-handers, 6-7% of the population, that is, 1 100 million people, naturally like to use their left hands. Because of its great nature, left-handed people inevitably become the targets of all classes. No wonder in the French general election, a candidate once put forward such a slogan: "vote for me, whether you use your right hand or your left hand, it is equally important to me!" " "

More and more children are encouraged not to cover up their left-handed habits. Many university statutes clearly state that "we need absolute equality in everything, regardless of your skin color, sexual orientation or left and right". Besides equality, some people go further.
