Information Bottlenecks

Think of an information bottleneck as a simple strainer that throws away useless details and keeps only what truly matters. An old art dealer named Joseph Duveen used this idea perfectly. He ignored regular gossip and only collected the deepest private habits of his rich clients. He threw away obvious facts. This method works because of a basic rule in communication. Claude Shannon, the father of information theory, defined information not by its content but by its unexpectedness. This means that things you can already guess have no real worth. A good bottleneck automatically blocks those boring details. It does not just collect random shocks. It traps only the few surprising facts that actually help you predict what will happen next. When you hold the only pieces of the truth that matter, you naturally control the entire game.
