The problem
Compliance (Saying Yes) erodes when it is left to instinct instead of method.
You were taught the moves piecemeal, never the whole model.

Step 1 of 5 · Reciprocation Tactic (Gift/Favor/Concession)
The debt is created by the giving, so timing (give first) matters more than magnitude.
Misconception
Practitioners believe the favor must be large or valuable to trigger repayment.
Reality
The obligation attaches to the act of giving, not the size of the gift; a small unsolicited favor can extract a disproportionately larger return because the recipient controls neither the initial debt nor the currency of repayment.

Step 2 of 5 · Commitment/Consistency Tactic
Written and public commitments bind far harder than private, casual ones.
Misconception
Practitioners think any initial 'yes' will seed later compliance, so they push for the easiest possible commitment.
Reality
Only commitments that are active, public, effortful, and freely chosen reshape self-image; a yes extracted under pressure generates no consistency pressure because the person attributes it to the coercion, not themselves.

Step 3 of 5 · Social Proof Tactic
People infer correctness from the crowd most under uncertainty—target ambiguous moments.
Misconception
Practitioners assume that emphasizing how many people fail to comply (litter, cancel, skip payment) will shame the rest into compliance.
Reality
Announcing a widespread undesirable behavior broadcasts it as the norm and increases it; social proof rewards the behavior you depict as common, not the one you disapprove of.

Step 4 of 5 · Liking Tactic
Similarity and cooperation build more durable liking than attractiveness or praise alone.
Misconception
Practitioners believe compliments only work when they are accurate and deserved.
Reality
Praise elevates liking even when the recipient knows it is untrue and even when it clearly serves the flatterer's interest—the affinity attaches automatically, before the accuracy check.

Step 5 of 5 · Authority Tactic
Signal your real expertise explicitly; people rarely dig for it themselves.
Misconception
Practitioners think substantive expertise speaks for itself and that signaling it is unnecessary or vain.
Reality
People respond to the markers of authority—titles, attire, credentials—often without verifying the substance behind them, so unsignaled expertise is routinely ignored while credible signals earn immediate deference.

The cheat sheet
- Reciprocation Tactic (Gift/Favor/Concession)The debt is created by the giving, so timing (give first) matters more than magnitude.
- Commitment/Consistency TacticWritten and public commitments bind far harder than private, casual ones.
- Social Proof TacticPeople infer correctness from the crowd most under uncertainty—target ambiguous moments.
- Liking TacticSimilarity and cooperation build more durable liking than attractiveness or praise alone.
- Authority TacticSignal your real expertise explicitly; people rarely dig for it themselves.
- Scarcity TacticFrame around potential loss, not potential gain—scarcity is loss aversion in action.
- Felt Obligation to ReciprocateIndebtedness is aversive enough to drive repayment exceeding the original favor.
- Drive for ConsistencyConsistency runs on autopilot and outlives the reasons that created the commitment.
