Talking in circles may be a misperception. N-types focus more on the connections among facts rather than the facts themselves. If one has 5 discrete facts then there might be as many as 120 connections so to fully describe each fact in a relative manner can seem circular because one has to come back to the same fact several times to describe different connections. LIIs and EIIs tend to do the permutations internally and don't voice them to others like some other types; and LIIs can better summarize their so-called circular thinking.
