This is a great way to put it. It’s a position I end up taking a lot—there are so many situations where no one involved has enough information to justify strong beliefs.
I have lately had a converse experience, where my superiors expect me to have strong opinions about things that are not even half-baked. Or rather, they ask me about it and even if I hedge and say "I'm not sure but..." they interpret it as gospel and move forward with laden expectations.
I have seen "I don't know. And I am pretty sure you don't either," effectively used to end pro-creationism arguments.
