The polygraph machine has been used as a psych tool for years; people believed it worked and would actually give their confessions up simply because they believed it worked.
It was a confession placebo.
It also turns out fingerprinting worked somewhat the same way, and there are other tricks that induce psychological beliefs of guilt and confessions through quite literally doing nothing.
A lot of DNA testing (though thank god they don't cover this) can actually be inconclusive. It's the notion that it CAN get you that get's people to crack; all you have to say is, "we have DNA" and they instantly know it's theirs and connect the dots and give in.
