I'm a retired DEA polygraph examiner, and stumbled across this podcast recently. Having just listened to the episode on '7 things not to do before a polygraph,' I can vouch that Mr. Goldberg is giving on-target advice. Every single thing he mentioned is a big mistake that I've seen multiple people make in the past, generally to their detriment, from researching countermeasures to showing up late or tired. With so much pop culture misinformation about the polygraph, this podcast makes a very refreshing and professional change.
