Before we talk about this, let's talk about the three links of brain growth and development. About 360 million years ago, marine animals gradually set foot on land, and the earth entered the vertebrate period. In order to better integrate into the survival on land, they evolved instinct. The structure of instinct is simple. It just needs to eat, drink and sleep. About 200 million years ago, mammals gradually appeared, and in the process of evolution, an emotional brain evolved.
In addition to basic emotions such as sadness and joy, they also have some advanced emotions, such as happiness, or fear of being hurt or sad. Up to now, about 250 million years, people have gradually evolved a rational brain. It enables us to think, create, develop trends and build infrastructure, so it has certain survival advantages on the earth. So in terms of time, the evolution time of rational brain is the least.
If instinct is compared to an old man of 100 years old, emotion is a 55-year-old adult, and rational brain is a full-moon baby. In addition, in the stage of human growth, the perfect growth and development period of rational brain is also the latest. According to age, the three brains grew well at 2 years old, 12 years old and 22 years old respectively. So before the age of twenty, people always seem a little naive, because their thinking is not perfect, the rational brain is far from the cardiovascular system, and the instinctive brain and emotional brain are closer to the cardiovascular system, so they can give priority to blood supply.
People often encounter a situation, that is, when they are anxious, their brains go blank. Finally, the rational brain is particularly slow. Its faster operation speed is 40 times per second, and its operation speed in instinctive brain and emotional brain is 275,000 times that of it. So once something happens, the instinctive brain and the emotional brain will respond first. We often see people who say what they say, but have a straight head and a big temper, because their instinct and emotional reaction are faster than their reason.
At this time, you will find that the rational brain actually has weak control over the brain. Therefore, many management decisions in people's daily life come from people's instincts and emotions. So, if you want to watch your mobile phone, just play. Eat hot pot if you want, whether you want to study or not. Do you want to lose weight? This is also the first reason.
The second reason is that people's thoughts are hard to hurt the subconscious, but the subconscious is hard to go up and down casually. Of the three brains, instinctive brain and emotional brain are the core subconscious, while rational brain is the dominant concept. Even if people don't notice, the subconscious will help them make decisions. For example, you have done it, but you can't remember why. And it is very important that the subconscious mind comes from instinct and emotion. They like to enjoy and release pressure, so they can't help but induce everyone to play and play.
The third reason is that thinking consumes a lot of kinetic energy. The net weight of each person's brain only accounts for 2% of the body weight, but it consumes 20% of the body's kinetic energy. In the process of life evolution, the key goal of his hand is to survive, so anything with high energy consumption will do harm to life. Therefore, people themselves don't like thinking very much, and the subconscious mind is very resistant to it, so people often follow their intuition to do what they like.
