Re: Why would anyone want to be married to someone who they have to give a polygraph

On a purely practical note it is very easy to fool a polygraph if you understand how they work.The original ones worked simply on body temperature,respiration and blood pressure e.g. If you were lying you would start to get warmer and begin to sweat which would lower your skins electrical resistance,then you would breathe heavier and you blood pressure would rise.This is on the same principle that getting an electric shock while wet or standing in water is far more dangerous than if you were dry.The more modern ones work on brain waves but are basically the same,they may use EECG or MRI scanners in extreme cases but they can be fooled too.If you are capable of getting yourself angry just by thinking about something or someone then you can fool any polygraph.Also if you simply give yes or no answers you don't give the operator enough to go on.
You may get the parking lot confession but that's about it.
But I fully agree with you, if you feel you need to polygraph your partner then I would just say adios.
