To your excellent analysis of these techniques, I'd add an overarching attitude that drives these narrative distortions of reality. That attitude is a fundamental disdain by the elites of the capabilities and value of us proles. Nonstop manipulative lying seems to me to require that disdainful posture. Also, based on my experience with a security clearance, I'd supplement Assange's observations on government secrecy by noting that most of the classified docs I reviewed and edited were terribly boring and mundane having little to do with "national security". Yet every time, I interacted with the crap, I felt the threat-pressure of the Espionage Act hanging over my head like a boulder ready to drop. A product of that aforementioned disdain is the desire to generate fear as a primary goal.
