When we read some theoretical books, we often find that the theory does not match the reality, how do you solve the problem of inconsistency?

That's because you haven't learned the theory yet!

We learn the theory at the beginning of the theory is the simplest theory, need a variety of harsh assumptions, etc., which is as smooth as the physical reality does not exist.

And this deviation of reality from theory is something we need to continue to learn, and then the theoretical models become more and more complex, correcting the previous models, and then they become more and more realistic!

In terms of economics, the traditional economics of the beginning of the study of the assumption that there is a rational man, but this is often irrational and the actual people against, but this is the cornerstone of economics, continue to learn, you will learn a variety of irrational human factors into account the model, so that and the reality is getting closer and closer!
