Why are most people right handed?

Everyone's left and right hemispheres of the brain have a different division of labor. Because most people, who are in charge of the left half of the brain of the right hand, also manage the work of speaking and using their hands, and because everyone loves to talk about gossip (talking) and gossip (hands) with their hands, the left half of the brain moves more (or is easy to move), so most people are accustomed to using the right hand.

Right-handed, in the narrow sense, refers to humans who habitually use their right hand for various daily activities, and broadly refers to animals that habitually use their right forelimbs for various daily activities. It can also be said that a person who is right-handed, with the right hand as the main and the left hand as the supplement. The phenomenon of right-handedness is prevalent throughout the animal kingdom, not just humans.

All animals in the Arctic, such as polar bears, including a Russian tribe in the Arctic Circle, are mostly left-handed. In fact, right-handedness is the way of life for most humans today.

Because we all have "logic" in doing things, and because the "reaction speed" required by various things is different, it is naturally divided into "rational logic" of "thinking carefully" but "slow" reaction speed and "perceptual logic" of "not need to think" and "fast" reaction speed. Some "rational logic" will be upgraded to "emotional logic" to quickly make various "judgments". They form "systems", such as:

We think "he hits me because he hates me", "if he hits me, then I'll run", "I don't like him like this, so I ignore him", etc., these are all "emotional logic". They have become a system of connections. And the real "ideal logic" is:

Why does he hate me, and what are these specific reasons? Why, when he hits me, I have to run? Why don't I like him like that?

etc., logic that requires a long period of observation and thinking.

Since "rational logic" and "perceptual logic" are each "system", then the "nerve cells" corresponding to them must also be systematic. So we find that the system of "rational logic" is in the "left brain" relative to the "right-handed", and the "perceptual logic" is in the "right brain". Because most people, who are in charge of the left half of the brain of the right hand, also manage the work of speaking and using their hands, and because everyone loves to talk about gossip (talking) and gossip (hands) with their hands, the left half of the brain moves more (or is easy to move), so most people are accustomed to using the right hand.

The reason why most people are left-handed is that they have a natural habit.

It's also possible to be smart!

The RS7182874 mutation in the PCSK6 gene is a key factor in determining whether a person is left-handed, and the probability of the mutation obtained in the experiment is also more in line with scientists' expectations.

About 85% of people prefer to use the left brain.

Right hand under control.
