Obviously one must use ones own discretion in applying these tools; as I stated, they basically rely on the knowledge of human psychology. It seems to me though, that, as Arthur reiterated, deception cannot be generally encouraged. In some situations, it might be deemed necessary, in others, it would only be frivolous; in still others, it could hamper the development of freedom in the other individual. I think that such freedom and self-reliance needs to be the goal of most interaction and relationships. In fact, true synergy is enhanced in that manner. We should use 'subconscious' cues to pick up information on another without great reservation, but using 'subconscious' persuasion ought to be considered much more sensitively. I hope this clarifies my concerns. I still, obviously, hold to my other statements in the first post as well.
