Here’s a hypothetical question- How much agreement do you need before you have a consensus? How certain do you need to be?
I don’t think there will EVER be 100% agreement about many topics in science. Natural selection is still denied by a few with biology backgrounds, despite it being the basis for modern medicine and substantiated by the fossil record. We don’t even know how gravity works, does that mean we should cancel all new airplane orders (some evidence suggests particles at opposite ends of the universe exert forces on each other instantaneously- in contrast to the speed of light “speed limit”)? So there will always be some degree of uncertainty, but that should not stop us from planning accordingly to what we think is most likely to be true. If you wait for certainty you will wait a long time, maybe forever, meanwhile the window of time you had to do something will have long past.
There was no 100% agreement that Iraq had WMDs, but I’d bet a years wages you supported the invasion on what intelligence we had. Why the double standard? Why is spotty intelligence good enough when it fits your views, but nothing short of 100% certainty is required for ideas you find unappealing?
