This may be repetitive, like most of my posts, but:
Any applicant taking a polygraph needs to realize that
it is a different situation, than being interviewed for a
typical DoD clearance. For a DoD clearance, by law, one
is required to be totally truthful on their SF86 and any
interviews; just look at the SORs, for the DoD appeal
cases. Sitting for a polygraph interrogation, this is not
the case, although, one is intimidated into believing so;
there must be a reason for this. Any derogatory
information, will be sent back to the DoD/DSS for review,
but, if one is not totally truthful during the polygraph, it
is not held against him (even if, someone is deemed
"deceptive") by the DoD; it is my understanding, that
the DoD/DSS does not look at the actual polygraph
results, but only at any derogatory information that is
"coughed up". My objection, and a good part of the
reason that I post here, is that applicants are kept
"in the dark", by both private corporations (employing
SSO/FSO security officers) and Intel agencies. I do
not recall, any mention that derogatory information
is sent back to the DoD/DSS, in any of the forms
that are signed, before sitting for the NSA polys (this is
probably the same, elsewhere); I do believe, it only
mentions that any unlawful activities admitted to, could
be reported to law-enforcement agencies. And we all
know, how issues get exaggerated, and how people
get pressured into admitting things they didn't do
(e.g., the typical, "how many times did you use pot",
routine), by polygraphers.
What it boils down to, is that the NSA, and others, must
be hoping for, and get off on, a total screw job of
applicants. Maybe they have a white board in back to
keep score on, just like at the end-of-the-month sales,
at car dealerships and time-shares.
