Not to get real dark and philosophical (but here goes) it took somewhere around 150,000 years for humans to go from spoken language to writing. And almost all of those words were irrational. From there to understanding and encoding what is or isn't provable, or is or isn't logically deterministic, took the last few hundred years. And people who have been steeped in looking at the world through that lens (whether you deal with pure math or need to understand, e.g. by running a casino, what is not deterministic, so as to add it to your understanding of volatility and risk) are able to identify which factors in any scenario are deterministic or not very quickly. One could almost say that this ability to discern logic from fuzz is the crowning achievement of science and civilization, and the main adaptation conferred upon some humans since speech. Unfortunately, it is very recent, and it's still an open question as to whether it's an evolutionary advantage to be able to tell the difference between magic and process. And yeah, it's scary to imagine a world where people can't; but that was practically the whole world a few centuries ago, and it wouldn't be terribly surprising if humanity regressed to that as they stopped understanding how to make tools and most people began treating tools like magic again. Sad time to be alive.
