That harmonizes with my experience. I was interviewing for a "top secret" job with the US and spent some time studying the system and looking over the appeals rulings of the clearance process.

Generally, the key things were, "are you a crook? are you liable to be bribed/coerced?".

E.g. one chap was a transvestite, but the appeals court ruled that since his wife and minister knew, it wasn't something that could be leveraged against him.
