Reading notes: the big picture-economic thinking in the real world.

It is often said that we should trust our intuition. Is this right or not?

Speaking of intuition, let's first look at two systems of our brain: intuitive system and reasoning system.

The operation of intuitive system is unconscious and fast, which depends on our instinct and intuition, and the speed of dealing with problems is very fast, but it often leads to system deviation.

The operation of reasoning system is slow, which requires us to mobilize our own logic and calculation ability, find the internal statistical law of things and make more accurate judgments. He makes few mistakes, but his biggest shortcoming is that his operation speed is too slow.

According to the book, intuition is the result of long-term human evolution. For example, why are we more credulous? Because credulity can increase your chances of survival more than unbelief.

For example, if you are a primitive man and there is a noise in the grass, it may be that the lion is hiding or it may be a gust of wind. Do you believe in danger? The result of credulity is nothing more than running for a long time Looking back, it was a false alarm, and the unfortunate result may be eaten by a lion.

The reason why we have intuition is that our human perception and thinking system is imperfect, our vision has blind spots, and our memory is chaotic, so we need the subconscious to fabricate a set of stories to support our imperfect perception.

Just like when we recall the past, we can remember the ins and outs of things clearly, but we can't remember the details. When people recall details, even if their intentions are extremely sincere, they will inadvertently fabricate facts and always believe their fabricated facts.

This is why we don't read biographies, especially autobiographies. Biography looks real, but it can't stand textual research. On the contrary, the novel sounds absurd, but it can truly depict human nature.

It may be fake, and fake is true.

We need to perceive things every day and make too many judgments and decisions. Much depends on our intuition. He relies on memories accumulated in the process of evolution for thousands of years, millions of years or even longer.

Why do we forget? Will it be delayed? Will you be depressed?

In fact, this is a self-protection mechanism, so in most cases, you still have to trust and respect your intuition, which is a useful name given to us by evolution, and this system has been running for millions of years, successfully protecting our survival and reproduction.

However, the emergence of systematic reasoning is very late. It only takes a long time for human beings to learn mathematics, logical reasoning and probability theory, so the slow operation speed of system reasoning is understandable.

Without intuition, we will not be able to act.

So, sometimes it's right to trust your intuition. Trusting intuition is not a bad thing.
