I have no inner monologue, unless I'm specifically thinking about what to say or write. Language is non-essential for thought. It's a way to map thoughts into a communicable form, but it's not thought. The concepts language describes exist independent of the language. Interestingly for me this translation of thought into language is much slower for writing than it is for speaking (with typing intermediate but closer to writing). I was diagnosed with Dysgraphia[1], as part of that evaluation I was given the Wechsler Adult Intelligence Scale—Third Edition (WAIS-III) when I was 16 years old, it gave me a verbal IQ of 147, a performance IQ of 125, and a full-scale IQ of 143. So I think I'd serve as a counterexample (sample size 1, though I know there are others) to the "left side of the curve" correlating with a lack of inner monologue (at least for this particular measurement, there are many others). Perhaps it goes the other way around, and the people who have to slow their thoughts down to translate everything into language are the left side of the curve, but more likely they're uncorrelated aspects of cognition.
