A heuristic is a “rule of thumb,” used because it is computationally cheap for a human brain and returns the right answer most of the time.
Analytical thinking uses heuristics, but is distinctive in ALSO using propositional logic, probabilistic reasoning, and mathematics—in other words, exceptionless, normatively correct modes of reasoning (insofar as they are done well) that explicitly state their assumptions and “show the work.” So there is a real qualitative difference.
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.
What is analytical thinking, but a sequence of steps of heuristics well vetted not to lead to contradictions?

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).
