Interesting stuff.

If I'm not mistaken, there are people or companies who offer to train you how to pass a polygraph or other lie detector tests? I think a Penn & Teller Bullshit episode talked about that, and it involved something simple like squeezing your butt cheeks when you answer.

Regarding, say, the reaction time test (e.g. the AIAT), couldn't a person just consciously delay his answers to all the questions, so that the RT of truthful responses would get close to that of non-truthful responses?

Although I can see that with a barrage of such tests, the truth would tend to creep up.
