Here’s how it’s done, according to Mamamia and expert in the field, Doug Williams…
After joining the police force in Oklahoma in his 20s, [in] 1972 and after going to polygraph school in New York, he was a certified expert in lie detector tests. All day every day, he [ran] polygraph tests.
Before long, he grew tired. He began to doubt their effectiveness, he knew how to intimidate people to get them right. He believed the “more heinous the crime”, the more “likely an innocent will fail”. After all, even the accusation of a serious crime is bound to induce the sweats and get your pulse up.
“I began to doubts in the tests after a while, I knew I could control my breathing but I didn’t know for sure how to control the cardio and the blood pressure,” he told the radio show. “It wasn’t until my friend came in and started talking about the pucker factor and tightening up the anal sphincter muscle when he was under stress.”
Yep, that’s right. All you need to do is, erm, clench your anus in order to beat a lie detector test.
Williams even tried it on himself and it worked. In fact it worked so well that in 2015, he plead guilty to obstruction of justice and mail fraud for teaching people how to pass lie detector tests. Whoopsie.
