Psychologist Steven Pinker in his book writes that the root cause of poor writing is what he calls “the curse of knowledge”. Basically the curse of knowledge is when a writer overestimates their readers understanding of an idea – creating confusion to the reader. Sometimes you need to understand one idea to understand the next.
It’s a similar idea Richard Feynman made in my article: 3 steps to learning any new subject.
