CONCEPT
The Prestige of the Source
Tarde's empirical law that imitation flows preferentially from positions of higher social authority to positions of lower — the infrastructure of trust in a world of infinite information and finite attention.
The law of prestige is not a claim about irrationality. It is a claim about the infrastructure of trust. In a world of infinite information and finite attention, individuals cannot evaluate every innovation on its merits. They must rely on proxies, and the most powerful proxy available to any social animal is the behavior of those they admire. If prestigious sources have adopted an innovation, the innovation carries a presumption of value that no amount of technical documentation could produce. The presumption is not infallible — prestigious sources can be wrong, can adopt for reasons unrelated to merit, can mistake novelty for value. But the presumption is efficient. It allows individuals to navigate landscapes of overwhelming possibility by following trails the most successful navigators have already blazed. The law explains why AI adoption propagated along specific prestige gradients rather than through random diffusion — and why rational-adoption models systematically mispredict when and how new practices spread.
