Not at all, just from what I gather from what I linked above. I've had an interest in psychology but never really studied it, I only found out about this from a "Personalities in the Workplace," class that turned into a "Buy my $95 Book."

I always wondered why I had a hard time speed reading, too. I guess there are tutorials or specific classes just to learn how to get rid of the dialogue. I can do it for a couple pages but I need practice.

I've been putting it off but I'm really interested to look up if schizophrenia, or specifically auditory hallucinations, can be a side effect of developing an internal monologue later in life, or just having it randomly come and go. Maybe they've gone 40 years without an internal voice and then one day it's just there and they're stuck thinking "WHO THE FUCK IS TALKING RIGHT NOW..." Your internal voice wouldn't sound like anything you've heard recorded.

Been curious ever since I watched 1899 and the one woman was absolutely convinced she was hearing God, but her whole just thought she was bat shit and just went with it to keep the peace.

This details some of the effects it can have. Basically having an internal dialogue can help with critical thinking and problem solving, but also slow down your reading speed if you can't turn it off, and being critical of yourself can cause self esteem issues. Mine distracts me with a thousand questions while I'm reading and before I know it I just glossed over ten pages and actually read nothing.

Meanwhile a majority of humans are walking around without an internal monologue
