Rhetorical Appeals
Ethos: Demonstrating Expertise
Establish credibility through showcasing knowledge, experience, and qualifications.
What & why
Ethos is a cognitive shortcut for trust. When a speaker establishes expertise, good character, and common ground, the audience's brain can conserve energy by lowering its skepticism filter, making it more receptive to the message.
Before & after
“Weak expertise: "I think this approach might work based on what I've heard"”
“Strong expertise: "Having implemented this methodology across 15 similar organizations, I've seen 30% efficiency improvements consistently"”
