That depends on how much we allow ourselves to learn.
That can be the hard part for me. If I have a general idea how something functions, with specifics here and there, I tend to believe that the parts I "know" are accurate. If they are not, then learning new parts to the puzzle can be hard since they do not fit in my mental picture.
Question everything, including basic assumptions. Shift your viewpoint and look at new problems from a different perspective. Especially listen to what others say and for what they do not say. Often, the unsaid parts contain the secret keys.
