We all build models of the world based on the information we’re exposed to. Majority of the information we have about the world doesn’t come through direct experience, and that makes it difficult for us to evaluate the accuracy of the information we operate on. As long as our direct experience doesn’t contradict our model then we have no reason to question it.
What we can be said to know fundamentally is what we have genuine experience with. Somebody working in a particular domain or studying it for personal interest has fundamental understanding of the problems solved in that domain.
