If they'll lie to themselves they'll lie to the Constitution. It always amazes me how lying to many people doesn't even register in their own biology. My ex-FIL was a polygraph examiner and we were shooting the breeze one night and he said one of the procedures was to put an envelope full of money in front of the person being examined and tell them if they told the truth they could have the money. Only then, with something to lose, would a lie register on the polygraph. Certain words also had to be chosen because some words like steal didn't register. I made a stereotypical comment about the usual suspects and he corrected me by basically saying it ran all spectrums from thug to theologian...so to speak.
