Absolutely. This is a distinguishing mark of experts in any field: they are quick to construct situations that disprove their mental models. So instead of looking for corroboration, they actively set up a situation which they think could disprove their hypothesis. This is a very economical way to zero in on truth. It's also why I ask seemingly stupid questions when someone teaches me something. It's not that I don't think I know the answer -- it's precisely because I think the answer is obvious. One out of fifty times the answer is different, and that tells me my mental model is seriously flawed and I should question everything else I thought I just learned.
