First principles reasoning is cognitively expensive—it would be pathological to derive your breakfast from thermodynamic principles. Reasoning by analogy is correct for most daily decisions.

Most people misuse this idea by either defaulting entirely to analogy or exhausting themselves on trivial choices.
