Ivy, don't you understand that you're asking a question to which the answer will either be given at the level of unverifiable personal insights, or this information is classified somewhere in intelligence agencies (the most advanced research on human psychology)?
At the level of personal insight, it's one-third in both cases (because at the level of personal insight, one-third of humanity is inherently deceitful, without going into details about how, why, and in what situations).
