Deep Canvassing / 深度说服

Deep canvassing is the one-to-one persuasion method summarized in 132.争论与说服：我们为什么吵架，怎么才算赢？. The source describes a sequence: build rapport, get consent to talk, ask the other person’s view, repeat and confirm it, clarify definitions, ask for a confidence score, ask why the score is not higher or lower, listen, summarize, and close without trying to dump all facts at once.

The episode stresses that deep canvassing is limited but meaningful. It may change only a small share of people, yet it matters in close relationships, political margins, and conversations where preserving the relationship is part of the goal.

Key Claims

• Direct evidence dumping can trigger defensiveness and reverse the intended effect.
• The method works by helping the person inspect their own reasons, confidence, and contradictions.
• Listening is not decorative; it is the mechanism that lowers threat enough for reflection.
• The source distinguishes deep canvassing from manipulation by adding a “step 0” ethics check about purpose, relationship, and value.
