I know that item-level thinking like this is necessary to gain emotional traction with people, but this issue is just so obvious at a systems-level.
the idea that we, right now the instant youre reading this, have discovered 100% of what there is to learn and 0% of what we know is wrong is so painfully, horrifically, obviously stupid (we've had computers for thirty years now, we're probably good for ETERNITY, right?). we both WANT and NEED a mechanism for dissenters and disinformation. misinformation is combat with MORE discussion, not less!
scientific consensus is not arrived at when every scientific paper says the same thing. this is a fundamentally wrong view of science and also reality. on any given topic, the corpus includes opposing conclusions. eventually we figure out why and discern the underlying principles.
to say anything but this is to make the existential case that people are not to be trusted with their own free will.
