The principle. Cialdini: people defer to credible authority. The catch: claiming authority directly ("I'm the best at this") destroys it.
Sideways authority signals.
- Specific data — "Across the last 412 deals like yours, the bottleneck was X."
- Diagnostic confidence — Naming the problem before they finish describing it.
- Calm corrections — Politely pushing back on a wrong assumption they made about their own market.
The third-party trick. "Our head of customer success has a rule with this — she won't take a kickoff call without your CRO in the room. Here's why." You inherit her authority without claiming it.
Watch out for. Authority without warmth = arrogance. Always pair with curiosity questions.
