Socratic Irony.

Socratic irony is where you pretend to be ignorant of something so you can get greater clarity about it. In short, it’s a lot like Cunningham’s Law.

Ancient Greek philosopher, Socrates would sit on some public bench and talk to whoever happened to sit next to him. He’d often open his dialogues by presenting a false or deeply flawed argument and go from there. He would ironically agree with whatever his partner would say, but then raise a seemingly innocuous question to challenge that position.
