There's one thing I laugh at with the "predictable ENTJ" thing.
An ENTJ requires you to provide ID to enter a building. You provide ID. You think, "ha! how predictable! ENTJ's security scheme could be passed through just by doing what he said! ha!"
An ENTJ again requires you to provide ID to enter a building. You think, "ha! I'm not authorized to go there! He would see that just by glancing at my ID card! Haha! I know better! I won't even try to go there! Ain't I clever!"
Now, is this what people talk about with "ENTJ predictability?" I.e. they do just what the ENTJ wants anyway?
