alt Hacker News>I've long considered writing to be the "last step in thinking". I can't tell you how many times an idea, that was crystal clear in my mind, fell apart the moment I started writing and I realize there were major contradictions I needed to resolve. Likewise I also have numerous times where writing about something loosely and casually revealed to me something that fundamentally changed how I viewed a topic and really consolidated my thinking.
I read somewhere that Thinking, Writing and Speaking engage different parts of your brain. Whatever the mechanism, I often resolve issues midway while writing a report on them.
I noticed that when speaking on a subject I tend to explain it in simple terms, but when writing, I tend to get bogged down in details, pedantry and technical language.
I started publishing my writing recently and I too often fall back into "debugging my mental model" mode, which while extremely valuable for me, doesn't make for very good reading.
I guess the optimal sequence would be to spend a few sessions writing privately on a subject, to build a solid mental model, then record a few talks to learn to communicate it well.
-- Similarly, journaling on paper and with voice memos seems to give me a different perspective on the same problem.
