It helps me to understand more clearly your argument. I still disagree with it though. I object to this:
zip(reasonable pair) > zip(policy+complex bias facts)
I claim this begs the question against OSH. If OSH is true, then zip(reasonable pair) ≈ zip(policy).
Indeed. It might be possible to construct that complex bias function, from the policy, in a simple way. But that claim needs to be supported, and the fact that it hasn’t been found so far (I repeat that it has to be simple) is evidence against it.
