Okay, so I saw this “lie detector test for cheating” thing trending, and I was like, “No way, that’s gotta be fake.” But my curiosity, well, it got the better of me. I had to try it out.
The Setup
First, I dug around online to find some DIY methods. I mean, I wasn’t about to buy some professional-grade polygraph machine. Most of the stuff I found was pretty basic – looking for changes in breathing, heart rate, that kind of thing.
I decided to keep it simple. I grabbed a blood pressure monitor my grandma had lying around, and I figured I could use my phone to record audio and keep an eye on the “subject’s” (aka, my very willing boyfriend, bless him) face for any telltale twitches.
The “Experiment”
I came up with a bunch of control questions. You know, easy stuff like, “What’s your name?” “What day is it?” Just to get a baseline. Then I slipped in a few… spicier questions. Things like, “Have you ever looked at another girl?” Stuff I already knew the answer, just to see the result.
- I strapped the blood pressure monitor on him. That thing was ancient, but it seemed to work.
- I hit record on my phone and placed it on the place that can see his face clearly.
- I started firing away with the questions.
Honestly, the whole thing was kind of awkward. He was trying to keep a straight face, but I could see him holding back laughter. I was trying to be all serious, like some kind of FBI interrogator, but I kept cracking up too.
The Results (or Lack Thereof)
The blood pressure monitor went up a little when I asked the “cheating” questions, but it also went up when I asked him if he liked my cooking, so… not exactly conclusive.
His face? Well, he’s a terrible liar in general, so I could usually tell when he was messing with me. But that’s not exactly scientific proof.
My Conclusion
My “lie detector test for cheating”? Total bust. It was fun, and we got a good laugh out of it, but it definitely didn’t give me any real insights. I guess those professional polygraphs are a bit more sophisticated than my grandma’s blood pressure monitor and my iPhone. Maybe I have to get a real one, who knows?
I think the key to a good relationship, is just to trust the person.
