If you observe that fingerprints can be matched, that’s all you need to know.

Meh, they do work. They just measure stress response, not truthfulness. The idea being that you’ll have a heightened stress response to a question you are lying about the answer to, which may or may not be accurate depending on individual and situation.

So they don’t work. They’re nothing more than pseudo-science gobbled up by “Truth, Justice, And The American Way” boomers who also watch NCIS and cheer when they blow up the bad guys on the big screen.
