Sure. The point is that “A->B; A, therefore B” is necessarily valid.
Unlike, say, “the risk of something happening is proportional to the number of times I’ve heard it mentioned.”
Calling logic a set of heuristics dissolves a useful semantic distinction between normatively correct reasoning and mere rules of thumb, even if you can put the two on a spectrum.
Propositional logic is made of many very simple steps, though.

Ohh, I agree. I just don’t think that there is a corresponding neurological distinction. (Original quote was about evolution).
