Presuming unconditionally for the sake of argument that this methodology actually works, I'm curious - would it be possible to make this type of thing self-sustaining? As in, the pigeons are rewarded (or not) based on their choices within only a few moments, given only the pigeons' input to the system. If pigeons were isolated and input was fed to them in parallel, then two or more inputs were taken to mean consensus and interpreted as evidential truth, would the distribution between individual pigeon responses mean that false positives would be evened out across the input distribution, or would such a technique result in progressive drift of accuracy? I'm guessing some form of drift would be quite likely, and that for a real-world system a firehose of already-known outcomes (go vs. no-go) would need to be fed to the pigeons to ensure accuracy. Taking it further, I wonder if the drift could be modelled and accounted for...
