I volunteered to take a polygraph and failed even though I was telling the truth. I was completely devastated as was my husband. I've since began doing research to try and understand how this happened and found that some people will have a false positive due to PTSD, Trauma, Anxiety, previous heart issues, or simply because the importance of the outcome itself. I then read that the new "lie detector" which is one done via an eye scan can be a good alternative in this case, I took one of those and passed it but my husband wont except that result as he feels its not valid. Can you help shed some light on the reasons for a false positive outcome and any information relating to the eye detector? What if I disclose everything and my husband still doesn’t believe I’m being honest?
