One ran along the lines of 80% identified the individual that was lying, or being misleading. If I find the link I will include it later. It is not a "smoking gun" that many here are wanting, but it did show promise in being able to use scientific methodology to gain a better understanding of how the behavioral observation systems work and can be improved on - or inevitably scrapped as non-viable.
