Have we not stopped for a second and thought that perhaps an internal monologue is associated with lower intelligence? Perhaps thinking quickly in abstract ways that are not internal monologues are a sign of higher intelligence, whereas people who think slowly in internal monologues may have lower intelligence, and perhaps slower processing speeds? It would explain why so few UNIVERSITY STUDENTS had an internal monologue, and even fewer have a consistent internal monologue. Anyway, that is just something that occurred to me, I don't really have a dog in the fight because I sometimes have an internal monologue and sometimes don't, it depends on what I'm thinking about.
