Why do we always trust the doctor, even though they might be wrong?
Authority bias is our tendency to trust, obey, or be persuaded by someone simply because they appear to have status, expertise, or power.
A doctor’s white coat, a CEO’s title, a professor’s confidence, or even a person speaking with certainty can make us lower our guard. We may assume, “They must know better.” Often, experts do know more. But authority is not the same as being right.
Psychologist Stanley Milgram’s famous experiments showed how far this tendency can go: many ordinary people were willing to administer what they believed were painful electric shocks because an authority figure told them to continue.
Authority bias can be useful. We cannot personally verify every medical diagnosis, legal opinion, or engineering calculation. Society works partly because we rely on trained experts.
But the wiser approach is respectful skepticism. Ask: Is this person truly qualified in this specific area? What evidence supports the claim? Do other credible experts agree?
Respect expertise—but do not surrender your judgment.
