Proof — Cheat Sheet

Core Doctrine

The Proof Braid: proof goes immediately after every promise or claim. A claim that floats alone is an invitation to disbelieve.
The Balance Scale: never make the claim bigger than the proof. Shrink the claim or grow the proof.
Match promise level to proof level — outlandish claims need proof HIGHER up in the ad, not buried.
Harder-to-fake proof is stronger. Independent verification beats self-reported every time.
Experiential proof converts hardest — the reader experiences the truth themselves instead of taking your word.
Psychological proof is the most underutilized — it creates the FEELING of truth without a single citation.

Emotion and proof trade off on a dial, and awareness sets the dial: the more aware the reader, the more proof; the less aware, the more emotion.
Unaware / problem-aware (cold): almost no proof. She needs the story, not the RCT. Heavy proof here reads as "being sold to" and kills the native feel.
Solution-aware: proof density rises — she's comparing options, so differentiation needs evidence.
Product / most-aware (offer-fatigued): heavy stacking — specific numbers, time frames, sources. Proof is what re-earns attention she's already spent elsewhere.
Emotions primary, proof secondary (grade-3 rule): make her feel first, then give her permission to believe.
Corollary: a stat block inside a confession-voice story ad breaks character. Match proof style to the ad's voice, not just its claim.

If the proof OPENS a loop → it goes in the ad. If it CLOSES a loop → it goes in the selling mechanism post-click (advertorial, lander, VSL).
The ad's job is attention + click. The unresolved claim IS the click reason — fully proving the mechanism on-platform satisfies curiosity and kills the click.
Ad-side proof (loop-opening or invisible): Testable Proof (an engagement device that happens to prove), Candid Communication (voice, not evidence), ONE named compound ("what's Lipout?" adds curiosity), guarantee on the free click (a CTR lever).
Post-click proof (loop-closing): studies & citations, review piles, certifications, track record, full before/after galleries, testimonial stacks.
Never source a curiosity claim in the ad — a vague "new research shows" on cold traffic is deliberate, not a gap.
Exceptions (proof belongs in the ad): solution-aware direct offers where the reader is comparison-shopping, claims already explicit in the copy (a floating "up to 22%" needs one grounding line), and anything compliance requires you to source.

1 Technical Jargon — precise, sophisticated language reads as expertise ("type-III collagen fragmentation").
2 Candid Communication — admit a limitation ("this won't work if...") and everything else becomes believable.
3 Explanatory Reasoning — explain WHY it works. A mechanism the reader can follow feels like proof.
4 Logical Arguments — build the rational case step by step; let the reader arrive at the conclusion first.
5 Guarantees — risk reversal. Confidence to guarantee IS evidence it works.

6 Testable Proof — give them something to verify on their own body/life right now ("check your feet and legs for these two things").
7 Demonstration — show the solution working in real time. Seeing beats reading.
8 Trials & Samples — firsthand experience before commitment.
9 Challenges & Contests — participation converts spectators into believers.
10 Comparisons — side-by-side against what they currently use.
11 Before & After — transformation made visible.

12 Studies & Research — scientific backing for the mechanism or result.
13 Stats & Evidence — hard numbers. Specific beats round ("273%" beats "3x").
14 Infographics — data made visual; charts read as objective.
Study hierarchy (Stefan): human double-blind placebo-controlled RCT → dosage match (study dose = product dose) → institution prestige (Harvard, Yale, Oxford, US-based).
Study mining: Science Daily summaries tell the full story and make selection easy.

15 Third-Party Certifications — external stamps (GMP, lab-tested, board-certified).
16 Track Record — years in practice, customers served, results produced.
17 Expert Endorsements — doctors, specialists, institutional credibility.
18 Media & Press Coverage — "as seen in" borrowed trust.
19 Awards & Recognition — industry validation.
"Harvard of X" trick (Brian): "I call them the Harvard of skincare" — undisputable, it's an opinion.
Proof stack layering: combine institutional quotes (Yale + Harvard + FTC) into one layered architecture, not a single citation.

20 Testimonials & Reviews — with SPECIFIC results ("14 lbs in 6 weeks" beats "it worked great").
21 Case Studies — one person's full story, problem to result.
22 Social Media Metrics — counts as consensus ("trusted by 3,416 mothers", sold-out waves, comment volume).
Exclusivity flip: "originally only available to..." is social proof via scarcity, then you open the door.

Blind ads can't name the product — but most proof types don't need to.
Works blind: Testable Proof (6), Explanatory Reasoning (3), Studies (12), Stats (13), Expert framing (17), Candid Communication (2), Comparisons vs the old way (10), narrator Before & After (11).
Route product-level proof (guarantees, certifications, reviews) to the lander/advertorial — the ad proves the MECHANISM, the lander proves the PRODUCT.
The doctor's-article bridge is itself credible proof — an expert curating a Top-5 list is an endorsement structure.

Claim feels hypey → don't cut the claim first; braid proof directly under it and re-read.
No studies exist → switch categories: explanatory reasoning + testable proof carry an ad with zero citations.
Ad reads flat/safe → you may be over-proving a small claim. Raise the claim to what the proof can carry.
Everything sounds like every competitor → they're all using categories 3-5. Steal share with psychological + experiential (1-11).
Reader skepticism high (sophisticated market) → open with candid communication: admit what the product WON'T do first.
Quick audit: mark every claim in the draft, then name the proof type welded to it. Naked claims = rewrite.
