Why analogies matter

Beyond the test.

Reasoning by analogy

Explaining an unfamiliar idea by mapping it onto a familiar one is how most teaching works. Recognising where the mapping breaks is what keeps it honest.

  • Every analogy is wrong somewhere; the question is whether it is wrong where it matters.
  • Arguments by analogy are suggestive rather than conclusive.

Practising

Notice the structure of explanations you meet: what is being mapped onto what, and where the map fails. That habit improves both the test and the thinking behind it.
