Disagreements about substance and expert credibility often go hand-in-hand and are hard to resolve on several issues including economics, climate science, and medicine. We argue that disagreement arises because individuals overinterpret how much they can learn when both substance and expert credibility are uncertain. Our learning bias predicts that: 1) Disagreement about credibility drives disagreement about substance, 2) First impressions of credibility drive long-lasting disagreement, 3) Under-trust is difficult to unravel, 4) Encountering experts in different order generates disagreement, and 5) Confirmation bias and/or its opposite arise endogenously. These effects provide a theory for the origins of disagreement.
