It's not clear any of that follows at all.

Just look at inductive reasoning. Each step builds from a previous step using established facts and basic heuristics to reach a conclusion.

Such a mechanistic process allows for a great deal of "predictability" at each step or estimating likelihood that a solution is overall correct.

In fact I'd go further and posit that perfect reasoning is 100% deterministic and systematic, and instead it's creativity that is unpredictable.
