Rhetoric and Audience
Rhetoric is the study of how language and other symbols persuade. It is not a list of tricks. Every persuasive text makes assumptions about who is listening, what they already believe and what they might do next.
The rhetorical situation
| Element | Question | Why it matters |
|---|---|---|
| Speaker or writer | Who is communicating, and what authority or experience do they have? | Shapes trust before the argument begins. |
| Audience | Who is being addressed, and who is left out? | Determines what counts as evidence, tone and relevance. |
| Purpose | What change in thought, feeling or action is being sought? | Distinguishes informing, persuading and manipulating. |
| Context | What is happening at this moment, and what has happened before? | Makes some arguments timely and others tone-deaf. |
| Message | What is the central claim, and what is left unsaid? | Reveals the campaign's priorities and blind spots. |
| Medium | Is this a speech, poster, video, social post, podcast or conversation? | Each medium affords different choices and reaches different people. |
Audience analysis without stereotyping
An audience is not a demographic box. It is a group of people with different knowledge, values, pressures and reasons to resist. Write what you know, what you infer and what you would need to ask.
| Question | What to write | Implication for the campaign |
|---|---|---|
| What does this audience already know? | Facts, assumptions and gaps. | Decide what needs explaining and what can be assumed. |
| What do they value? | Security, fairness, belonging, autonomy, status, care, tradition, novelty. | Connect the message to a value the audience already holds. |
| What do they need? | Time, money, information, confidence, permission, support. | Remove barriers rather than merely urging action. |
| Why might they resist? | Cost, inconvenience, distrust, shame, fear, competing priorities. | Answer the strongest objection in the campaign itself. |
| What are they being asked to do? | A concrete action, a change of mind or a change of feeling. | Make the ask specific, achievable and ethical. |
| Who is not in the room? | People affected by the issue but not addressed by the campaign. | Consider whether the campaign speaks about them without them. |
Ethos, pathos and logos
| Appeal | What it draws on | Campaign example | Risk |
|---|---|---|---|
| Ethos | Credibility, character, authority and goodwill. | A campaign cites a reputable health body and shows its own evidence and limits. | Borrowed authority, false expertise or hidden interests. |
| Pathos | Emotion, values, empathy and imagination. | A story about one person's experience makes an abstract issue concrete. | Using emotion to bypass thought, or exploiting someone's suffering. |
| Logos | Reasons, evidence, logic and structure. | A campaign shows the scale of a problem and the likely effect of a proposed change. | False precision, cherry-picked data or a conclusion that outruns the evidence. |
The three appeals work together. A campaign that is only logos can feel cold; one that is only pathos can feel manipulative; one that claims ethos without evidence can feel hollow.
Worked example: a school food-waste campaign
Situation. A student group wants to reduce food waste in the school canteen.
| Element | Analysis |
|---|---|
| Audience | Students who buy lunch, canteen staff who decide portions, and families who pack lunches. Each group has a different reason to resist. |
| Purpose | Reduce the amount of edible food thrown away each day, not simply make students feel guilty. |
| Ethos | The campaign uses the canteen's own waste data and names the students and staff involved. |
| Pathos | A short story about a typical lunchtime makes the waste visible without shaming individuals. |
| Logos | A week-long audit shows how much waste is produced and which changes are feasible. |
| Message | "Take what you will eat, and tell us what you would actually buy." |
Common errors
- Audience as a stereotype. Assuming age, gender or income predicts what people think.
- Purpose drift. Trying to inform, entertain, persuade and sell at the same time.
- Appeal spotting. Naming ethos, pathos or logos without explaining how it works.
- Emotional bypass. Using fear or shame to stop the audience thinking.
- Missing audience. Designing for the teacher rather than the people who need to act.
