Audience Analysis

Audience analysis is the precondition of all effective rhetoric. The classical tradition was unanimous on this point: before invention (what to argue), before arrangement (how to organize), before style (how to express it), the rhetor must understand the audience; who they are, what they believe, what they value, what they will resist, and what it will take to move them.

This is not merely the advice to "know your audience" in the vague sense of imagining that someone is listening. It is a systematic, disciplined process of inquiry into the specific human beings you are trying to reach; a process that produces specific insights that should drive specific choices in content, argument, tone, and emphasis.

The Three Dimensions of Audience Analysis

Effective audience analysis operates along three dimensions simultaneously:

Analyzing Audience Knowledge

Misjudging what the audience knows is one of the most common communication failures. The speaker who explains what the audience already knows is patronizing; the speaker who assumes knowledge the audience lacks is incomprehensible. Getting this calibration right requires honest inquiry, not assumption.

Distinguish between: expert audiences (who share your technical vocabulary, your background assumptions, and your familiarity with the relevant research), intermediate audiences (who have some relevant knowledge but not full expertise), and novice audiences (who are encountering the subject for the first time). Each requires a different level of explanation, a different vocabulary, and different choices about what can be taken as given.

Analyzing Audience Attitudes

Beyond knowledge, analyze the audience's pre-existing attitude toward your subject, your argument, and yourself as a speaker:

• Favorable audiences need less persuasion than motivation; they already agree; the task is to strengthen commitment and move to action
• Neutral or uninformed audiences need clear explanation, compelling evidence, and a reason to care
• Resistant or hostile audiences require your most careful rhetorical work: begin with common ground, acknowledge their perspective honestly before arguing against it, and build credibility before making contested claims

The strategic implications differ significantly. The approach that motivates a favorable audience may alienate a hostile one; the even-handed acknowledgment of complexity that builds credibility with a skeptical audience may frustrate a sympathetic one who wants clear advocacy.

The Perelman Test

Chaïm Perelman's concept of the universal audience provides a useful evaluative tool for audience analysis: after designing your argument for your specific, particular audience, ask whether it would persuade a broader audience of reasonable, informed people. If the answer is no; if your argument works only because of this audience's specific biases or limited knowledge; that is a signal to revise. The best arguments are those that work for the particular audience while also being genuinely reasonable by broader standards.
