Daniel Kahneman and Gary Klein collaborated on a paper trying to understand when does intuition work. It turned out a lot of it is just they were studying different peoples intuitions. If an environment is completely random, like 100% random coin flips, then there really is no expertise that can be gotten. So I found that as a helpful construct when thinking about whether to trust the expertise of people in different fields.
