Writing in simple language is only a small part of the Feynman technique. In fact, the Feynman technique is a widely used learning method, because it touches on the fundamental way humans access information. If you understand the basic structure of the human brain, we know that there are both "rational" and "emotional" people living in the brain. The rational person is superior, but the emotional person is more powerful, so most of the time, our emotional behavior is dominated, including the reception of information. It's not hard to understand why each of us is naturally attracted to the lighthearted and simple things. For example, when reading a book or an article, we tend to listen to the story rather than the reason. Once you understand that, I think anyone who writes will adjust the way they create.

For example, first use the appropriate story to arouse the interest and attention of the other side of the "perceptual person", and then convey the truth to the "rational person" through the "perceptual person", this is a good strategy, two people will be very satisfied. Especially the knowledge, the reason of the book, it is best not to pile up abstract concepts, let a person feel very deep, see the clouds in the fog. If the chart, the model, the concept, perhaps the "rational man" has no opinion, but the "perceptual man" has long been impatient, so he took the "rational man" hand said: "no fun, let's go." The strength of the sentient man makes it difficult for didactic writing to attract readers. Of course, we should not be a "clickbait" who attracts people but has nothing substantive to say, so that the "rational person" will not be satisfied. For example, writing in a conversational style will make the essay feel natural. Many new writers take writing too seriously and start preaching as they go along. In fact, if you think of writing as a conversation with an old friend, the process will be different. You see, chatting is such a relaxing thing, and it is something everyone likes to do. You can't be too serious, you can't be too condescending, you can't just talk about yourself, you have to observe the other person's feelings, so good writing is talking, and good talking is writing. After all, if you can use simple language, don't use complex language, which is one of the core Feynman techniques.

But simplicity doesn't just mean ease, it also means simplicity and image. For example, I consider myself familiar with the concept of deliberate practice. I often use concepts like "information gaps" and "comfort zone edges" to instruct others in reading books. I sometimes use the "one jump" metaphor to explain it, and I think it's already a big deal. And Mr. Mu Xin, a literature master, said this when talking about reading: "Start reading, be shallow. Shallow enough to be commanding when you start." And it hit me like an Epiphany. No abstract concepts and nouns, a few words, easy to understand, but the essence of deliberate practice. Once again, reader Clear Sky asked me: What is the relationship between the concepts of prefrontal cortex, metacognition and rational brain? An analogy struck me: the prefrontal cortex is the "body" of the rational brain and metacognition. This time I was able to turn the tables on you, because it is a very rare and precious thing to think of a suitable analogy. Most of us underestimate the power of analogy, thinking it is just a figure of speech in literature. In fact, it is our way of thinking, but also our cognitive tool. George Lakoff, the founder of cognitive language, once defined and evaluated analogy in this way. One thing to know another thing, is the essence of learning! Because humans can only explain the unknown by the known, it is difficult for us to understand something we have never seen in a vacuum. And analogy is the bridge between the unknown and the known. If you can use the right analogies in your writing, you can simplify a lot of concepts and make them accessible and understandable in a really amazing way. Just like the "11 floors", "sewing buttons" and "two little people in the head" mentioned above... These analogies require little mental effort and allow you to easily understand complex principles. No wonder Li Xiaolai always sticks to this rule when writing: make extensive use of analogies and try not to use any rhetoric except analogy and parallelism... If you practice this principle from time to time, you will find yourself not only writing better, but also learning better.
