Run a Product Comprehension test

Which explanation makes people get it, checked against their own description of what the product does and who it is for.

Product Comprehension is for the launch problem: the thing is new, or complicated, and two explanations are on the table.

What it measures

The primary question is a 1 to 7 rating of how clearly the version explained the product, and the verdict is decided on the average for each version. Two open questions sit under it, and they are the real value: what people think the product does, and who they think it is for. The card labels this set as built from measurement principles rather than drawn from a specific body of research.

What people are asked

• "How clearly did it explain the product?" on a 1 to 7 scale from "Not at all clear" to "Very clear". This is the question the verdict rests on.
• "What does this product do?" in their own words.
• "Who do you think it is for?" in their own words.

When to pick it

Pick this when understanding is the risk: a category nobody has a mental model for, a feature that needs a beat of setup, a product whose value is not visible in a shot of it. Skip it when the product is already familiar, because comprehension is not what is failing. If the message is a claim rather than a mechanism, Message Clarity is the lighter read. If the piece has to end in an action, add Call-to-Action Clarity to the shortlist.

What the verdict looks like

The rating decides the verdict, under the usual conditions: both groups at the size committed at launch, balanced dropout, and a gap clear of chance. Short of that, a directional advantage or "too close to call". Read the two open questions whatever the verdict says, because a room that understands the product but describes it as something you do not sell has told you the most useful thing in the report. See Understanding your verdict.

What it cannot tell you

Comprehension is not desire. A version people understand perfectly can still move nobody, so pair this with an intent read like Purchase Intent before a launch call. Self-rated clarity is also softer than a true comprehension quiz: people report feeling clear more readily than they turn out to be, which is why the open answers are there to argue with the score.
