"Hare Brain Tortoise Mind" is a great book that goes into how this works and how to work with/against it.<p><a href="https://www.youtube.com/watch?v=aB_4YU6UtCw" rel="nofollow">https://www.youtube.com/watch?v=aB_4YU6UtCw</a><p>tldr: There is a background, non-verbal process in your brain that has the advantage of a larger working set size than your foreground verbal thinking. It is able to observe and consider more stuff at once and find associations better than your conscious thought process. But, it has several disadvantages. It takes time to do it's processing. You can't will it into action. It communicates non-verbally with your foreground process. It doesn't work under pressure (thus the need for relaxed, unfocused time). The non-verbal understanding is difficult to deconstruct, generalize and reapply. It can lead to you solving a problem, not understanding how and not being able to solve a variant of the same problem.<p>So, the general recommendation is: If you have a complex problem to solve, first absorb as much information about the problem as your brain can hold. But, do not try to solve anything. Then, go take a break. A walk in a natural environment is preferable. Don’t think about the problem. Relax in a low stress environment. Let your background brain have a chance to chew on it and maybe bubble up some suggestions.
