It's hard to tell if one does or doesn't have an inner monologue/dialog.

It's the standard "is the color I call 'yellow' the same yellow color that you call 'yellow'?" question.

We have no frame of reference for what an inner monologue is really like for other people.

How many gradations are there? 0 = none, 1000 = max (I can hear my voice in my head as clearly and cogently as you can hear my voice when I'm explaining something to you?)

0 = none, 3 = max, and almost all humans are either a 0, 1, 2 or 3?

Until we get neuralink's descendent implanted and can share each other's consciousness, we won't know for sure. And probably not even then.

I don't understand your comment. I literally have no words going through my head most of the time, unless I'm composing text or speech as I am doing right now. The rest of the time as I go about my business and solving problems throughout the day: zero words. Nada. Zilch. Furthermore, having to think in words is a mental strain on my energy level that I don't feel when non-verbally solving problems. I could be doing very intense engineering work and find it less mentally taxing than forcing myself to speak for a few minutes or compose an email. It's a qualitative difference, not a spectrum.

For me, I can drive for example, and think about complex topics with words running through my mind at the same time, without it distracting from my ability to drive.
