Lie detection will always be a useless technology, because there is little binary to truth/lie in which language cannot manipulate. A truth can be a lie with nothing but tone let alone different wording or nonverbal indication.
That's why the entire history of it is based on guessing based on emotional response, and why the people most likely to be evil or lie are easily able to just fool it. Making it useless for its most necessary function.
That iscwhy advanced lie detection needs to be developed.
