No the sources are from CIA and FBI agents trained in interrogation and spotting lies (and wanting to sell their books, like researchers want their research read). One of the agents used these signs to know that Timothy McVeigh was lying. They also give a counter to your hand-pick: Observe the person when they are not lying/natural environment, note any ticks, and discount these when interrogating.

Place your lead hand thumb on your cheek and two fingers on your chin and imagine you are talking to someone standing one meter from you. Do you feel sincere?

There is plenty of research that show that lie detection is not all bunkum, and that techniques such as cognitive overloading help catch lies and lower defenses (which need focus and don't come naturally to most people).

I really can't think of anything I could do that could make me feel insincere when I was being sincere. This sounds a bit like the discredited claims about power-posing, or smiling to feel better etc.

I'm sorry but I really think you're letting yourself be taken in by some extraordinarily shoddy science and by the pseudo-scientific claims of people who are either engaging in magickal thinking and really believe they can "tell when you're lying" or just charlatans trying to take advantage of the naivete of others.
