The Truth Behind The Lie Detector Guy

Polygraphs measure stress indicators. You know what must be pretty stressful? Being wrongly accused of doing something horrible and knowing that your body's micro-reactions could destroy your life. It's no wonder that polygraphs have led to countless false convictions and that many jurisdictions are rightfully not allowing them to be used in a legal setting.

Fun fact: the creator of the lie detector actively said that his invention was false, it couldn't detect lies, but no one took him seriously. He called it his own Frankenstein's monster

I have been a part of lie detector training for government agencies and they never tell you "that was a lie" They usually give you the test, leave the room, and then come back and say something like "we got some weird readings about some of the questions, would you like to explain what was going through your head that might have lead to those results" They never even tell you what questions they were. They want you to expose yourself and then they just keep asking if there's anything else until you stop giving information. The actual polygraph is basically just to make you scared and confess

John: I hate Liars!!! Also John: It reads lies 100% accurately 💀

As someone who immediately looks and feels guilty in any situation, one of my biggest fears is being polygraphed as I would 100% incriminate myself for whatever they happen to be asking.

I was expecting you to hire John and have him come to your house, where you reveal you've actually become a certified polygraph technician and that he is the one to be hooked up to the polygraph machine.

My dad failed a polygraph in the 1970's. They were trying to figure out who had been stealing from the cash register at his summer job and he was so nervous being questioned by the police that he completely failed it even though he hadn't done anything. What saved him was that the girl who worked the shift after him just completely broke down and confessed everything the second they hooked her up. Pretty much the first thing I ever remember hearing about the "lie detector" was my dad saying they were unreliable😂

As a child I was once told that those machines by store exits detect shoplifting by measuring how nervous you are. As a kid with anxiety I immediately became nervous around those devices out of fear that I'd for some reason be nervous and be accused of shoplifting. Welcome to how anxiety works and also what would probably happen if I ever had to take a polygraph.

The fact that lie detectors were ever allowed in court as evidence is…mildly disturbing.

It always bothered me when there would be a lie detector test that just reads your pulse so if someone was just UNCOMFORTABLE OR NERVOUS their pulse would spike and everyone thought they were lying it’s infuriating

The fact that polygraphs have gone from being used to falsely accuse people of crimes to being advertised as this quirky way to detect lies. One of the things I've learned in the first few months of my intro to clinical psychology class is that there's no physiological associated with lying. It's awful that influencers and celebrities are still promoting it as a valid test. It feels like the cultural perception of polygraphs will never go away as long as people like John continue to falsely assert its validity to people who don't want to look into it themselves.

The more I learn about how lie detectors work, the more I realize that people with anxiety or neurodivergent people (or BOTH in my case) would be royally screwed if they had to use one.

As an autistic person i have been accused of lying many times for shit i didnt do just because im always a little awkward So its good to know that some guy named John gets to do that to people 'professionally'

It's weird that this guy is the only lie detector that you can get, it's like if there was only one person to depend on for a ghost investigation.

So basically the only people guaranteed to pass a polygraph are people who are completely comfortable with whatever they’re saying… and since we know that plenty of people are very comfortable with lying…… and there are plenty of people who are uncomfortable just being asked questions while hooked up to a machine in general……….,

Always thought it was fishy that he was always the guy doing the polygraph test for everyone. My reaction was "oh it's the guy that was in the Try Guys video!" and "Oh, it's him again..."

The fact Shane Dawson used this guy on Bobby Burns and asked if Bobby was using Shane for views and Bobby said no and the lie detector guy said it was a lie and then they chose to keep that in the video 💔 Bobby was sabotaged

Being forced to take a lie detector is like a weird fear of mine bc i have anxiety and im like fully afraid they're gonna think im always lying

“I hate liars” makes entire career out of technology that is literally a lie

We need john to take the lie detector test
