Polygraphs, at best, potentially measure nervousness. The assumption is that lying makes people more nervous than telling the truth.
As others have said, the science behind this is bullshit.

I’ve taken 3 polygraphs in my lifetime, and I lied on all three. None of the polygraphers caught the lies, but all three accused me of lying on other questions where I told the truth.
Polygraphs are voodoo. I might take one for a job, if it were required, but I would never agree to one for the police. I would NEVER trust my freedom to one.
