Using Analogies and Comparisons

Analogies are one of the most powerful tools in argumentative writing. A well-chosen analogy can make a complex point instantly clear, expose hidden assumptions, and shift the entire framing of a debate. But analogies are also risky — a weak or forced analogy can undermine your argument more than support it.

This lesson teaches you how to find effective parallels, when to use them, and how to recognise when an analogy is helping or hurting your case.

What Is an Analogy?

An analogy is a comparison between two things that are different in most respects but similar in a relevant way. The purpose is to use something familiar or well-understood to illuminate something less familiar or more contentious.

Example:

"Requiring social media companies to verify the age of their users is no different in principle from requiring shops to verify the age of customers buying alcohol. Both involve restricting access to something potentially harmful to young people."
