Argumentation Techniques

Argument by Analogy

Support conclusions by comparing similar situations with known outcomes.

What & why

What it is
An argument that supports a claim by mapping it onto a separate situation whose outcome or principle is already accepted, then transferring that conclusion across. Its force depends entirely on relevant similarity: the two cases must match on the features that actually drive the result, not on surface resemblance. A strong analogy clarifies and persuades at once, while a loose one invites the rebuttal that the cases differ where it counts.
Why it works

An analogy borrows belief from a case the listener already accepts and transfers it to the new one. By mapping an unfamiliar situation onto a familiar pattern, it lowers cognitive load and lets people reason about something hard using something easy. The shared structure feels self-evident, so the conclusion arrives as a small inference the listener makes rather than a claim you assert. That sense of figuring it out for themselves tends to make the position stick and feel more their own.

Before & after

These are fictional teaching examples, not accounts of real events.

Before

“This is like that other thing we did once.”

After

“A shared tool shelf would work like our book swap: people take what they need and bring it back, and the shelf stays stocked because the same neighbors use it. The book swap has run for two years with very few losses, so a tool shelf for the same neighbors should work too.”

When you’ll use it

Change management: "Implementing this software is like renovating a house - it's disruptive initially, but the long-term benefits outweigh temporary inconvenience."

Team building: "A successful team is like an orchestra - each person has different skills, but they must work in harmony to create something beautiful."

Innovation arguments: "Investing in R&D is like planting seeds - you don't see immediate results, but the future harvest justifies the effort."

Risk assessment: "Ignoring cybersecurity is like leaving your house unlocked - most days nothing happens, but when it does, the consequences are severe."

Pro tip

Identify relevant similarities between situations and explain why the comparison is valid.

Questions & answers

What is argument by analogy in business presentations?

Argument by analogy supports conclusions by comparing similar situations, showing that what worked in comparable circumstances should work in the current situation. It makes complex ideas accessible through familiar comparisons.

How do I create effective analogies for business arguments?

Choose truly comparable situations, highlight relevant similarities, acknowledge important differences, use familiar examples your audience understands, and ensure the analogy genuinely supports your argument rather than just illustrating it.

What makes analogies weak or ineffective in professional settings?

Weak analogies involve superficial similarities, ignore crucial differences, use unfamiliar comparisons, oversimplify complex situations, or stretch comparisons beyond reasonable limits. Strong analogies share fundamental characteristics.
