This aligns well with a lecture from the University of Chicago I watched recently[0], which explores how many academics use writing as a tool for thinking (What the article describes) and don’t think about the reader. Writing is an incredibly powerful tool to form thoughts.
However, as the lecturer in the video details, don’t expect the writing done for thinking to be useful to readers! When we think, there is usually a certain incrementalism, whereas when we read we’re trying to resolve dissonances in a current mental model. That’s a key distinction, it means you need to make people care or understand why their mental model is broken when writing to informs reader. When we write for our own thinking, we usually understand the general problem already and are just traversing the problem space to better understand different components.
