I believe the "unethical amnesia" to be somewhat overblown. Those who have a habit of lying, will just continue to do so, regardless if it's something they did 5 seconds ago or 5 years ago. The truth is intact except they will even lie to themselves, not just other people. Also I believe a lot of what makes people do and say what they do, is strictly speaking, not quantifiable on a physical level alone. It is like trying do differentiate the daily food intake between identical twins. Doesn't matter. In this case, truth is a universal constant whereas lies only exist in the physical plane.
