ok, my last try....

polygraphers are duping you about how the polygraph really works. they are not duping you into an admission of something.

it would only be duping if they said for example, only drug usage in the last 12 months is relevant and after you admitted to it, they told you the standard is actually 5 years.

as for the quote about who would be honest about stuff. thats simple. A person of integrity does not apply for positions if they do not meet the drug usage standards. if you are willing to lie and rationalize just for your own advantage, you should not get the job.
