I agree in principle that note-taking can enhance memory and retention; but I've found that today, typing my notes does the trick for me - especially because I use indented/hierarchical lists frequently, and update/re-org them as I go; so they help me build a mental model of material or actions we covered.
By the end of note-taking session, my OneNote file will have notes organized in the way which makes sense to me and in which way I want to remember them - whereas hand-written notes would (for me) be inherently more sequential. As yourself therefore, I retain the list of key points or actions far better than if I didn't take those notes - even if I don't refer to them later.
(as well, I'm a touch-typist, so I can look at the person or whiteboard/screen while typing, which again I personally couldn't do while hand-writing).
So it may be whatever works for any given person - or, whatever people get used to. It'd be curious to see if typed notes would provide same benefit to you after, say, a few months commitment? Or it may be that I switched early enough in life; or, to quote Lady Gaga, maybe I was just born that way :->
I need the notes too. I rarely refer back to them but writing them is an art for me. It almost functions as a memory palace of sorts. I’ve done notes on an iPad Pro but I prefer pencil, colored pens, and paper.
If I type them, I don't hear it either.
I almost never go back to notes. The process of writing them, however, is critical for me. Maybe it's my ADHD, dunno.
For what it's worth though, I'm usually taking notes on a surface device of some kind, rather than pen and paper.
