The amusing thing about the GIGO argument is that it is not IRV that 
does best when dealing with noisy votes. That honor goes to Condorcet 
(as shown by Brian Olson's simulations). Even Approval does better than 
IRV as noise increases.

And still, the three-scenarios argument holds. If there is some kind of 
weird IRV-specific GIGO so that IRV is really good, then BTR-IRV is no 
worse, fuzzy epistemic limits or no.

Finally, specificity can hit both ways. Perhaps the specificity works to 
degrade DLW's unproven IRV/Approval hybrid, and what we need is a robust 
noise-handling method like Condorcet. Perhaps, perhaps. Without any 
evidence, anybody can play that game and it will get us nowhere.
