I was taught some 30 years ago that best practise is to write clear contemporary notes because transcribing them later can lead to self-censorship, deciding to omit what might seem irrelevant at the (new) time, but subsequently becomes important, or incorrect re-interpretation.

I am not sure I follow this line of thinking? You are saying that after the fact you somehow understand the context less than you did at the time of initial writing?

I find the absolute opposite to be true- At the time of the lecture or meeting or whatever, I am just trying to capture everything. What is truly important and what is noise is not clear to me at that point. Also in the beginning stages of a class or project certain concepts or decisions seem very new or foreign, and a few months later they are deeply ingrained and no more likely to be forgotten than understanding what gravity is.

By far the most successful study technique I have ever used is recopying my initial notes. The second set is much more coherent, organized, and focused on the tricky bits while removing things that I thought might be important at the time but ended up not being important.

I think someone did you a major disservice 30 years ago.

This is an interesting idea, and I will chew on it for a bit.

I'm not sure how I would achieve it though? The right initial structure isn't usually clear at the beginning of a conversation/research session/whatever I am taking notes on.

How do you find time for that?

I have a personal "shut down" period at the end of the day where I close out my browser tabs that are no longer relevant, and review all the scribbles I've written down in a notebook, transfering the few important ideas to the relevant longterm storage, or to the appropriate project file's todo list, etc.... I also write down the first thing I'm going to do in the morning (because I don't believe the first thing to do should just be "catch up on Slack" or "read email").

Helps me clear my mind, and it saves me a lot of time in the morning, because I can start work and have some wins for the day within 15 minutes...and that momentum carries me through....

Also, the shut-down period is nice, because when I'm tired at the end of the day, it doesn't take a lot of energy.

In the words of the Merovingian: "Yes, of course. Who has time? Who has time? But then if we never take time, how can we ever have time?"

I do the same, and transcribing notes doesn't take all that long. You tend to summarize in the process, so it's not usually a 1:1 copy.

I also put references to my (page-numbered) paper notebooks in my notes file, and vice versa, so stuff that would be very long to transcribe doesn't usually have to be transcribed at all.

I guess I prioritize it over other things which I would otherwise be spending the time on. You might just be a more busy person than me?

I also have a pretty strong aversion to headless-chicken-mode, having seen it as a pathological disaster spiral at a couple of places where everything is urgent all the time, and so you never have time for anything. Being in too much of a rush to do things properly is a trap.

I find as an employee I have to fill and empty my head a lot. I have a good short-term memory, but things that I don't write down tend to slip out after a week or two. "Oh, I worked on that thing? I don't remember that."
