Causality, like all human concepts, is a product of the necessity of humans to act, in order to alter the course of events, so that they can consume the difference. Causal understanding is then bounded by human perceptive ability, processing power, in real time. And from this perspective, whether something is causally replicable on one end, or correlatively positive but causally uncertain at the other end, is only as relevant as the cost and risk of the actions necessary to achieve the outcome.
We often confuse truth in the abstract, with truth-for-action. Truth in the abstract is a metaphysical tautology. Truth-for-action is simply scientifically pragmatic. Evolution works by trial and error, and so do we.
