Deep canvassing replaces adversarial persuasion with structured, nonjudgmental exploration. The facilitator first asks where someone stands, often using a zero-to-ten scale, and then investigates why that rating feels right. Follow-up questions invite the person to articulate values, formative experiences, and reasons both for and against the position. Asking why the rating is not lower evokes the person’s own counterarguments rather than imposing an external case. A relevant personal story can then connect an abstract issue to lived experience and expose inconsistencies without humiliation. The mechanism works by lowering reactance, preserving social dignity, and shifting cognitive labor to the person whose belief may change. Instead of winning a debate, both participants examine the disagreement shoulder to shoulder, allowing self-reflection and cognitive dissonance to produce self-persuasion.

Extracted from Masters in Business. David McRaney described how the Leadership Lab refined deep canvassing through roughly 17,000 recorded conversations and extensive A/B testing after California’s Proposition 8 defeat.
Core principles
- 01All durable persuasion is self-persuasion
- 02Listening reduces defensiveness and reactance
- 03People need room to examine how they formed a belief
- 04Personal experiences reveal tensions hidden by abstractions
- 05Preserving dignity keeps difficult conversations open
How to run it
- 1
Leave the debate frame
Treat the disagreement as a shared mystery rather than a contest. Signal that the person will not be mocked, shamed, or forced to defend their identity.
Pro tip Approach the issue shoulder to shoulder instead of face to face.
Watch out Any suggestion that the person should feel ashamed can end genuine exploration.
- 2
Establish the current position
Name the issue neutrally and ask the person to place their view on a zero-to-ten scale. Let them choose the number without correction.
Pro tip Use the scale even for low-stakes topics when practicing the method.
Watch out Do not turn the rating into a score you must defeat.
- 3
Explore why that number fits
Ask why the chosen number feels right and listen for values, experiences, social influences, and received wisdom. Reflect what you hear without judging it.
Pro tip Stay with this stage as long as needed; McRaney notes it may occupy much of the conversation.
Watch out Do not substitute your reasoning process for theirs.
- 4
Evoke counterarguments
Ask why the rating is not lower, prompting the person to produce reasons that point away from their current resistance. This draws out change-oriented reasoning without prescribing it.
Pro tip Phrase the question with sincere curiosity rather than as a trap.
Watch out Giving corrective advice too early can trigger reactance.
- 5
Connect the issue to experience
Invite the person to recall a personal experience related to the issue. Explore whether that experience fits comfortably with the abstract position they stated.
Pro tip Ask about people they know and care about when the issue concerns a social group.
Watch out Do not exploit painful disclosures or manufacture emotional pressure.
- 6
Hold space for dissonance
Allow contradictions and uncertainty to remain visible while the person reflects. Preserve their ability to save face rather than demanding an immediate concession.
Pro tip Silence and reflective listening can be more useful than another argument.
Watch out Pushing for a declaration of conversion can cause the person to retreat.
- 7
Review movement without forcing closure
Ask where they now place themselves on the scale and what, if anything, shifted. Accept modest movement as meaningful and leave the conversation open.
Pro tip Measure success by honest reflection, not total agreement.
Watch out Do not misrepresent a small change as complete persuasion.
In the wild
After losing California’s Proposition 8 campaign, canvassers returned to communities where the measure had failed and asked residents why they voted against marriage equality. They listened without confrontation, reviewed recorded conversations, and repeatedly tested which conversational elements worked. Questions about gay family members and their prospects for love made an abstract political issue personal for some participants.
→ The refined method produced reported attitude shifts of roughly 10 to 12 percent, far above typical movement on single political issues.
McRaney demonstrates the structure with The Adam Project. The interviewer asks for a zero-to-ten rating, explores why six feels right, compares the film with The Godfather, and asks why the rating is not four. The questions reveal the listener’s standards for entertainment without challenging the original opinion.
→ A low-stakes topic exposes values and reasoning that a simple like-or-dislike question would leave hidden.
Common mistakes
Leading with facts and links
Sending a book, video, or website assumes your reasoning can be copied into another person. It bypasses the personal reasoning process required for self-persuasion.
Triggering shame or social threat
Humiliation makes the person defend their standing and identity. Once social threat dominates, exploration gives way to reactance.
Treating the exchange as a contest
A win-lose frame rewards rebuttal and face-saving rather than joint investigation. Both parties become more committed to defending their opening positions.
Is it for you?
Best for
It is best for patient one-to-one conversations about emotionally charged beliefs, identities, or behaviors.
Not ideal for
It is not ideal for emergencies, coercive situations, public point-scoring, or conversations where the other person cannot participate voluntarily.
From the transcript
“people talk themselves out of their position when you just stood there and listened”
“The most important aspect of this is non judgmental listening”
“you go from face off to shoulder shoulder”
