"Information is the resolution of uncertainty"
About this Quote
That’s the subversive genius of the line. It smuggles a philosophical claim into a technical definition: knowledge isn’t a sacred substance, it’s an update. Information isn’t what a message is about, but what it does to the receiver’s state of doubt. Shannon’s intent was pragmatic and foundational. Working at Bell Labs in the mid-20th century, he needed a way to engineer communication systems: how to encode messages, survive noise, compress signals, and still recover what was sent. You can’t optimize a feeling. You can optimize uncertainty.
The context matters because it explains the austerity. Shannon’s information theory emerges from a world of telephone lines, radio static, and wartime cryptography. "Resolution" is almost legalistic: ambiguity settled, the case closed. It’s also quietly political in today’s culture wars over data. If information is simply uncertainty reduced, then a flood of content can still be informationally empty if it clarifies nothing. The line anticipates our era’s problem: noise masquerading as knowledge.
