Munger suggests that investors should establish multiple thinking models 

Munger believes that in our daily life, there is a disease of thinking level called "hammer syndrome". In short, if you only have a hammer in your hand, you will see nails all over the world. From a profound perspective, we think we are thinking with the brain, but in fact, we are thinking with the existing thinking model in the brain. If the outside world has implanted some kind of thinking model in our brain, we will naturally use this kind of thinking model to think. However, if this kind of thinking model is wrong, or only one kind of thinking model is used to look at the world, our cognition of the world will be distorted. This is the so-called "hammer syndrome".

In real life, the education we receive is basically from general knowledge to professional knowledge, that is, with the improvement of education level, we will develop in a relatively narrow field. However, after entering society, we will find that many problems can not be easily solved by means of a narrow field. In the process of education, we have been implanted with a certain fixed mode of thinking, so it is difficult for most people to quickly integrate into society after leaving school. They often have to go through social "reeducation" to get rid of the original thinking mode and successfully gain a foothold in society.

Therefore, Munger suggests that investors should establish multiple thinking models, learn widely about the thinking models of mathematics, physics, biology, philosophy, psychology, economics, and other different disciplines, integrate them, and then establish their own investment methodology based on these thinking models and theories.

Most people may worry that they do not have the time and energy to study so many subjects. But Munger's multi thinking model does not require us to study each subject in-depth, but only the real truth in each subject. In fact, in every discipline, the real truth may only account for 5% of the total content, but it represents 95% of the importance.

So, where are these great principles? Munger believes that the so-called grand principle is actually the basic thinking of each discipline. In our learning process, the content related to thinking is usually the main course for freshmen and sophomores. In the actual learning process, we do not want to learn profound knowledge, but to learn different ways of thinking in different disciplines. For us, each discipline is a perspective of thinking, just like glasses with different functions, some are myopic, some are farsighted, some are microscopes, and some are telescopes. We study the world through glasses with different functions, so as to form comprehensive cognition from different dimensions and angles, which is the essence of learning different disciplines.
