Polygraphs aren’t really used for lie detection. Think of it as a tool for an enhanced interview. It allows for the interviewer to have many more dimensions of straws to grasp at in assessing you. “Lies” are assessed as anomalous readings measured against control questions. This is something polygraphers are open about and inform you of the control stage during the start. Afterwards, it’s all really an internal battle. There’s even various stages cues wherein they might leave you in the room alone to fester in your thoughts. So really it’s not whether youre a liar or not, but more of having a consistent nature
- rubicon33 7y agoKnowing this, it seems like it would be very easy to throw them off your lying scent. I've had a few experiences in my past that, when brought to memory, cause fairly large adrenaline spikes. Certainly, the memories increase my heart rate by just thinking intently about them. In theory... couldn't you bring these thoughts to memory - at random? When asked about what you had for breakfast, for example. It would appear as an anomaly... But if you did that often enough, the interviewer couldn't trust the anomalies.
- nocsi 7y agoSure if what you lied about is a big deal. The polygraph room is purposefully sound-dampened. I remember being able to abnormally hear more of my body (heartbeat, saliva, etc) in the room. What I'm getting at is that during a polygraph, it's very doubtful you're going to be daydreaming while undergoing a 4-5hr long interview lol. If you want to know how to 'cheat' the polygraph - I'll tell you. There's no magic to it, you just have to really not give a shit about anything really. In the context of the US government, they want workers that are first and foremost, resilient to manipulation. Historically, the biggest traitors in the country have been money-driven, hence the emphasis on identifying huge debt areas. Such debt can be leveraged against people easily. The other thing to consider is, do you think they want someone that's too honest? What about in the scenario that you're being interrogated by a foreign agency, you're telling the truth but you're sweating balls. A polygrapher can latch onto these signs and use them against you. And someone that's emotionless and doesn't really give a shit about anything good or bad? Pass the polygraph with flying colors, have fun swaying someone that can't be bought off nor exempts guilt.
