  "gloss": "Redundancy in communication is inefficient for one message or interaction but efficient for a space in which many interactions keep taking place",
  "mechanism": "Measured on a single exchange, saying more than strictly necessary wastes capacity: a sports report that calls the same player 'the England international', 'the 20-year-old' and 'Real Madrid's top scorer' repeats itself. Measured across the ongoing space of exchanges, the overlap pays: each variation reminds the reader of background facts, disambiguates through context, and gives {{peripheral_hitchhiking}} information a vehicle to travel on. In a cell, an apoptosis channel with less than one bit of {{channel_capacity}} wastes signal for one cell but smooths the response of the population. The value lies in overlapping, non-identical repetition, in line with {{meta_modularity}}, not in identical copies, which only guard against loss. Machine languages that demand one fixed reference per referent are efficient per message and poor at this.",
