Because most people I know can read without mouthing the words. At any rate, we can just test both cases if people who claim one or the other are willing.

I'm not sure why this seems like a problem, or why you have to criticize my default position, but my own personal views on the matter aren't important here.

I don't see how reading has anything to do with internal monologue. Do you hear the words you read when reading? If so, it surely has to be slow as hell.

I did get relatively good scores in reading speed back in primary/middle school when we took such tests, so maybe there's an explanation. At the same time, writing/speaking is a very resource-intensive task for me so I tend to be silent a lot (and then drop a pile of sentences on the unsuspecting people I'm with)

well, all the same, I think we should verify these claims .. I think part of the pushback to this is that it might make a group of people look dishonest if we can in fact detect subvocalization in people who have made this claim, but it's entirely possible that you are experiencing both and not realizing it. A bifurcation of sorts? In any event, we should support/expect further testing.
