Being comfortable with saying "I don't know" a lot is something I had to kind of train myself to do. It's part of realizing that this is a truly enormous field that we're in, and nobody could possibly know more than a fraction of it. Anyone who doesn't say it much is either spending all of their time in a subset of the field that they know very well, or is throwing around bullshit, either from fear or bravado.
