Cialdini's Principles of Influence

Thinking Tools6.3 Implementing the Action PlanAlso known as Six Principles of Persuasion, Influence Principles Checklist

Originated by Robert B. Cialdini (Influence, 1984).

Seven principles (reciprocity, commitment, social proof, liking, authority, scarcity, and unity) used as a checklist to plan honest persuasion and to recognize pressure tactics.

When to reach for it

Buy-in is needed from people who owe the proposal nothing, or an offer on the table seems to push harder than its merits.

How it runs

  1. List the people whose agreement is needed.
  2. Go through the seven principles one at a time.
  3. Note which already work for or against the case.
  4. Use only the principles that are true of the situation.
  5. When receiving a pitch, name the principles it leans on.
