In this episode, Adam investigated the truth about lie detectors, fingerprint analysis, eyewitness testimony and much more. Here are the sources he used.
"Humans are complicated. The truth isn't something you can detect with a machine… Back in the Dark Ages, they would force criminals to hold a red hot iron to see if it burned them. If it did, it meant you were lying."

"Truthful people fail polygraphs all the time, just because they're sweaty and nervous. And all you have to do to beat it is stay super chill. Criminals do it all the time. Some infamous examples include Gary Ridgway, aka the Green River Killer..."
