No. Science is testable. Science requires proof. Science without testability and proof is not science. A scientist who says, here is my scientific thesis, but i can't prove it, is not celebrated, even if they did get some flash of insight. And statistical evidence could be considered proof in the absence of the ability to run a test, but you have to at least have that before you can call your "scientific" idea something other than a philosophical idea. EDIT - You seem to be mixing up the two disciplines of science and metaphysics as well. You also have a very biased approach because you talk about delusion being endemic, instead of just the delusion as how things are.
