  "gloss": "Natural work overlaps: doing more of one task always means doing a little less of another, and imperfect alignment between them packs more function into the same agents",
  "mechanism": "In natural systems, computations are not cleanly divided among dedicated components; the same pathway serves several tasks at once, which partly trade off. The apoptosis signalling channel has a {{channel_capacity}} of only about 0.92 bits, so it does not reliably carry the self-destruct signal. That looks like a fault for the cell, but it also damps over-reaction to unreliable signals and stops a dense area of cells dying at once, which would harm the organism. Two levels, the cell and the cell population, are optimised together by one compromise. In human organisations this looks like instructions sent but not obeyed. Rather than the clean division of labour of {{multi_modularity}}, the result is overlapping work, in line with {{meta_modularity}}, and lack of perfect alignment becomes a feature rather than only a defect.",
