“Basically he’s saying lie detectors don’t work.”
I once failed a lie detector test when I was telling the truth.
Just being nervous can cause false readings. Don’t be naïve and take a lie detector just because you know you are innocent.
Never speak to the police without a lawyer and never take a lie detector test.
I took a lie detector test when I worked for Radio Shack.
Someone (I suspected an employee) stole a receiver. When I discovered the theft, I called Loss Prevention.
They subjected me to a polygraph. Afterwards they wanted to know what I was hiding because I was “controlling my breathing.”
They proceeded to ask permission to search my car and my house. I would have to produce a receipt for any Radio Shack merchandise found. I owned stereo equipment I had purchase many years before and told them so. They said I better have a receipt or I would be fired.
I quit a few days later.
I had the same experience. Failed a lie detector test years ago when I worked at a company that was trying to determine if employees were using drugs. I have never used any illegal or recreational drug in my life; I don’t even like taking prescription drugs. But I failed the test because when they asked me if I’d ever shot peanut butter intravenously, I cracked up laughing.
I thought, “Is that even a thing? What, are people not getting fat enough putting food in their mouths; now they’re injecting peanut butter directly into their veins? Do they put peanut butter in the right arm and jelly in the left one?” The needle bounced around and for that, I was branded a suspected drug user. Junk science.
