The Power of Persuasion
Lesson Goals
- Identify the "Three Pillars of Persuasion" in a speech.
- Recognize rhetorical devices (Rule of Three, Repetition).
- Detect manipulative tactics like "False Dichotomies."
Advanced speakers—especially politicians, lawyers, and advertisers—don't just want you to listen. They want you to act. They use specific tools to hack your brain.
1. The Rhetorical Triangle
[Image of rhetorical triangle ethos pathos logos]Aristotle identified three ways to persuade someone. When listening, identifying which one the speaker is using helps you analyze their argument.
Credibility & Trust
Emotion & Stories
Logic & Facts
2. Tricks of the Trade
Listen for these common patterns. They are designed to make speech memorable and hypnotic.
"We must represent the past, the present, and the future."
"Do we want to fail? No. We want to succeed."
"You are either with us, or you are against us." (Ignoring the middle ground).
Strategy: Identifying Bias
Manipulative speakers use "Weasel Words". These are words that sound confident but are actually vague.
"Experts say that this product is the best."
Ask yourself: WHICH experts? If they don't say who, they are likely trying to manipulate you.
Practice Activity: Deconstruct the Pitch
Listen to the sales pitch. Identify the technique used.
- "I've been a doctor for 20 years..."
(Technique: Ethos / Pathos / Logos) - "Imagine the pain of losing everything you love..."
(Technique: Ethos / Pathos / Logos) - "It's safe, it's cheap, and it's effective."
(Technique: False Dichotomy / Rule of Three)
