"Prediction is very difficult, especially if it's about the future"
About this Quote
Coming from a physicist who helped found quantum mechanics, the subtext sharpens. Bohr lived in a world where certainty had to be renegotiated at the atomic level, where observation changes what’s observed, and where probability is not a temporary placeholder for ignorance but a basic feature of the system. So the quip isn’t anti-intellectual; it’s anti-overreach. It mocks the human impulse to treat models as mirrors rather than tools.
The line also works because it hits beyond physics. “Prediction” is the modern fetish: markets, elections, product launches, pandemics. We dress guesses up in dashboards and confidence intervals, then act surprised when reality behaves like reality. Bohr’s humor is a warning label: humility is not a personality trait, it’s an operating system. If even the people who measure the universe for a living are wary of the future, everyone else should be too.
