The WTS is the poster child for Hassan's description of using mild control techniques. Step by step by step they fit the pattern. That is not and cannot be an unconscious coincidence.
My thought on this point is that those mind control techniques that were observed were just that, observed. In other words, instead of being a set game plan that is intentionally executed, they are merely the traits exhibited in high control environments. As such a pattern, observed in various organizations, it actually would be a coincidence, wouldn't it? Just like people that are enablers often follow the same patterns of codependence, or the way that any set of humans seem to follow the same group behavioral patterns. The enabler doesn't sit down and go through a step by step checklist of how to manipulate another human being, they just behave a certain way that others in similar circumstances follow as patterns of human behavior responsive to certain circumstances.
It's kind of like I have ADHD. I had no clue that I had it until in my thirties. I had certain issues in life, and then found this group of people that had the same behavioral patterns, even a checklist of them (the DSM). I never set out to act a certain way, my behaviors were just indicative of an issue that I had, not intentional at all.
