When to use it

Use it to decide how much detail and what kind of evidence to include for a particular audience.

How to apply it
  1. Assess how motivated and able your audience is to think carefully about the message.
  2. For engaged, able audiences, lead with strong, well-evidenced arguments.
  3. For less engaged audiences, make sure credible messengers and clear cues support the message.
  4. Remove weak arguments, which can backfire with careful thinkers.
  5. Aim for central-route agreement on important changes, as it tends to last longer.
Tip: Raise relevance to the audience personally and they become more likely to engage with the detail.
