"An economist is an expert who will know tomorrow why the things he predicted yesterday didn't happen today"
About this Quote
Peter, best known for the Peter Principle, had a lifelong interest in the ways institutions reward confidence over competence. This quip extends that critique to the prestige economy of economics. Forecasting is sold as science, but it functions publicly like weather talk with higher stakes: useful, sometimes, but structurally insulated from falsification by complexity, revised models, and selective memory. Tomorrow's explanation becomes a way to preserve authority today.
The subtext is sharper: economists aren't merely wrong; they're protected by a system that treats uncertainty as proof of sophistication. When predictions miss, the miss can be reframed as evidence that the world is "too complex", that shocks were "unforeseeable", that the model was "mostly right". Peter's timing matters too. Writing in an era when economists were becoming celebrity technocrats, he punctures the aura of inevitability around their pronouncements. The line is funny because it's mean, and it's mean because it hits a public suspicion: expertise that can't be held accountable starts to look like theater.
