Is triangulation the natural mode of individuals who do not recognize themselves as independent agents? Do they instigate behavior because they are unaware of their own presence or involvement? If so, that would also explain their resorting to the non-sequitur, which is really just a verbal manifestation of disconnection. Lack of awareness -> disconnection from agency.
