Logos: Comparative Analysis

Use systematic comparisons and benchmarking to support logical conclusions.

Last updated

What & why

What it is
A logos technique that evaluates options by examining them against each other on explicit, shared criteria. Rather than asserting that one choice is better, it lays out the relevant dimensions (cost, speed, features, risk) and shows how each alternative measures up, so the audience can reach an informed conclusion. Its credibility rests on fair grounds for comparison: a representative set of options and consistent criteria, not a benchmark chosen to flatter a predetermined answer.
Why it works

Value is hard to judge in isolation, so a comparison gives the audience a reference point, and against a clear benchmark an option's strengths and costs become legible. Setting choices side by side on shared criteria also reduces cognitive load: instead of holding scattered details in mind, listeners read one structured contrast. Contrast sharpens perception, making differences that would blur on their own stand out. The framing stays persuasive when the comparison is fair, since a stacked or selective benchmark, once noticed, undercuts the whole case.
