What is the difference between probabilistic and deterministic models?
Content: Such physicists claim that the decay of radioactive particles is an example of a “random” event that is not predetermined. I do not profess to know if the universe is deterministic or probabilistic, but I do tend to disagree that quantum physics disproves Causal Determinism. ( Bruce Silverstein's answer to Does quantum mechanics undermine hard determinism? and/or Bruce Silverstein's answer to Is it likely that we live in a completely deterministic universe, governed by laws of physics that we simply might not fully grasp? ). As I see it, the difference between a deterministic and probabilistic system is not based on the predictability of an outcome, but on the actual physical process by which activity occurs — whether or not it is detectable or predictable. While quantum physics does seem to establish that certain activity within the universe is beyond the capacity to be fully understood, much less predicted, that does not mean that such activity is truly random and not fixed by laws of the universe that are outside of our comprehension, much less apprehension.
