The background investigation helps determine the applicant's honesty, trustworthiness, reliability, discretion, and unquestioned loyalty to the United States.
Loyalty and blind obedience are not necessarily the same thing. I'm fond of Carl Schurz's aphorism: “My country, right or wrong; if right, to be kept right; and if wrong, to be set right.”
What am I being obtuse about and why are you talking about selective and biased reasoning? The aspect of the comment I was responding to was "One of the most selective criteria." Do you know what the most selective hiring criteria is for TS/SCI work?
Instead of beating around the bush, why don't you tell us what agency you work for, what department and what is the most selective criteria to TS work.
