Okay, let me try this again. Here's my guess, (if I am allowed to post this), and it's only a guess:
They HAVE accessed materials dealing with psychological research. Toward the end of the last seminar that I took at L.E., the seminar leader started talking about the next seminar in the series, saying that it would deal with "brain science." She told us that we would all experience an "amygdala hijack."
There are certain practices that mental health professionals are aware of, but DO NOT use, because they have been determined to be potentially harmful, and have no therapeutic value ~ similar to the way a doctor would not prescribe Schedule 1 drugs, such as LSD.
The psychologist Phillip Zimbardo conducted the infamous Stanford Prison Experiment in 1971, which he ended early because he decided it was unethical. The Milgram Experiment is another example. Both of these experiments deal with the way that normal adults respond to perceived authority, (it's scary). Reports of these experiments are readily accessible to the public, along with much other literature about unsavory psychological experiments, such as learned helplessness in animals.
Professionals will not use these tactics, constrained as they are by a code of ethics. LGATS are NOT beholden to these ethics, however, and have no regulatory board. They have you sign a form that acknowledges that they are NOT mental health professionals. I have often speculated that this was an end-run around malpractice suits.
