The study you cite saw an effect from manipulating theories of willpower, so self-knowledge isn’t all that’s going on.
I mention the self-knowledge possibility because I think it possible that if there are people with limited willpower, they might be able to fake limitless willpower for a time (but not change themselves entirely). Even in that case, the obvious thing to do is pretend it’s true until it fails, not hope for it to fail.
