As an addition to my last toot. You can use knowledge in as many ways as there are people on earth. In my dealings with controlling people (when I can't avoid them ugh) I think I most commonly make them as uncomfortable as possible by steering them into situations where the uniformity, conformity and obedience they require to feel safe isn't easy to achieve.
Eventually avoidance behaviour kicks in. Theirs.
But knowing how easy they are to disrupt and upset is the key. Then just use it your way
