I think this is likely it. In my opinion, it reminds me of autoencoders. Having to compress the information means understanding the content enough to discard unnecessary bits.

I can roughly keep up in real time with speaking on the keyboard. Even though speaking is a bit faster than my max rate around 90 wpm, by dropping filler words and gaps I can mostly avoid summarizing and quote verbatim. When transposing at full speed like that, I feel like a conduit at times, very little sticks deeply in memory.

Contrast with writing notes, where I'll only write down things I find particularly important. Most of the time I'm just trying to actively listen.

Purely anecdotally, I feel like when I am typing and summarizing to the same compression ratio as writing, my retention with typing is better, because I can do it without looking, it's faster, and I can tune back in to the speaker.

On the other other hand, with a laptop open, I'm much more likely to get distracted with emails/tasks.

Bottom line, I think we need to study more axes of this problem, if only because it gives neat insights into cognition.
