The polygraph to me is about the ability to lie without being detected. Psychopaths pass them with flying colors.
You tout that as a "good thing" -- you've proven you can tell lies, come join our team.
What kind of people do you end up with in the end then? -- yes people who are tough, but also psychopaths, people who can lie well and can then easily turn on you and sell that $150M spying project to someone else for $50k.
