Low intellect was the context I came across the concept. It didn't occur to me before, but retroactively it did seem to fit that only people I know that aren't the brightest were verbalizing their own thoughts while thinking. I have no clue whether lack of internal monologue is associated with lower intelligence, though my guess would be that there probably isn't strong correlation, but that's just a baseless guess. I could see how someone with lacking internal monologue would do a couple of things a bit different than someone with internal monologue and typing out thoughts would seem like a pretty decent fit.

Thinking about it a bit, typing out things might be pretty similar to actually verbalizing things in your own head, as written words correspond to said words, meaning that writing out thoughts might just have the same goal and effect as saying them in your own mind. Just a hunch that I didn't sit on for long, but so far I could see it as an actual thing.
