I don’t know

I’m looking for resources on “I don’t know.” I thought there was something in the study vault, but I can’t find it.

I’m not getting the result I want because of blocks my brain throws up when I think “I don’t know.” It generates a variety of feelings, and the only time it creates a result I like is when it comes with an intense urge to find out. But most of the time it’s an excuse to shut down and avoid.
