there aren’t massive fluctuations in this based on sex, race and nationality

Wrong, you made a false assumption about my claim and poorly absorbed the data.

Those fluctuations absolutely exist, but they are counted within the 38% who are sentient.

The same is seen with people who have an internal monologue are more disagreeable than those without one.

Uh, yeah. That's called overlap. Same separation of sentience vs non. Both cross sections (asch has been repeated far more times than any study into internal monologues) imply that some humans are simply not independent entities capable of free thought. And both seem to imply that number is well above 50%.

You can go back further if you like, and Plato was saying the same thing about the cave.

The number of people who are not capable of free thought or "disagreement" remains the same across all subtypes. It's in the actual freethinker range that you find the additional differences.
