Concept · Cognitive Bias: Social and group biases

Authority bias

Origin: Milgram, 1963

Biological Parallel

In baboon troops, a dominant male's direction of travel determines group movement even when lower-ranking individuals have superior environmental knowledge—a juvenile who knows where water is located defers to the alpha's ignorant choice. This authority bias evolved because in most ancestral contexts, following high-status individuals improved survival: they gained status partly through superior judgment. The bias persists even when the correlation between rank and competence breaks down.
