I have an erratic heart beat it is not serious or anything but will it cause a fail on a test? No real way to keep it the same beat with truth or lies so just wondered any help would be great. thanks
While there are no scientific studies on the influence of irregular heart rates on polygraph outcomes, because of the way polygraph "tests" are scored, one wouldn't necessarily expect such a condition to significantly influence the results. However, it is important to bear in mind that polygraphy has not been shown through peer-reviewed research to reliably detect deception in people without any heart rate irregularities under field conditions.
The consensus view among scientists is that polygraphy has no scientific basis (https://antipolygraph.org/articles/article-018.shtml). A statistical analysis (https://antipolygraph.org/articles/article-051.pdf) (255 kb PDF) conducted by Dr. Alan P. Zelicoff on data from the best published field studies suggests that "if a subject fails a polygraph, the probability that she is, in fact, being deceptive is little more than chance alone; that is, one could flip a coin and get virtually the same result for a positive test based on the published data."
Thanks for input. Seems like im doomed to fail, or pass with flying colors. After reading the book anyway that's about how I feel. Was plenty of good info in it but all in all it seems to come down to what the man/woman giving the test feels and nothing more. I am glad I Found this site gave me a lot to look into before I proceed in LE. So thank you again
I wish you all the best in the hiring process, and hope that the polygraph won't end up wrongly disqualifying you.
