Direct Experience: No Secondhand Attitudes
- Attitudes formed from direct experience usually conform more closely to actual behavior than those formed more indirectly
- Help your audience feel that they are affected by the problem you describe or empathize with those afflicted
- Example of direct versus indirect experience

Effort Required: Degree of Difficulty
- Find the easiest ways for listeners to express their support
- Suggest ways that even complex solutions can be implemented in relatively simple, straightforward steps
- Example of effort required with solutions to opioid addiction

Elaboration Likelihood Model
- The elaboration likelihood model (ELM) of persuasion explains how listeners cope with and sort persuasive messages
- There are two primary routes to persuasion according to ELM:
- Central Route (skepticism): Use of reasoning and evidence
- Peripheral Route: Considering likeability, credibility, celebrity, physical attractiveness, and body language cues
