Evidence-Based Persuasion

Research-backed principles of persuasion — the WHY behind effective copy.

Evidence Marking

Most marketing advice mixes proven research with folklore. This skill separates them:

  • 📚 = Peer-reviewed academic research (cite with confidence)
  • 💼 = Practitioner-validated (widely used, not academically tested)

Top 5 Principles

#PrincipleFindingSource
1Loss AversionLosses hurt ~2x more than equivalent gains📚 Kahneman & Tversky, 1979
2Processing FluencyEasier to read = more believable📚 Reber & Schwarz, 1999
3Social Proof75% conform to group behavior at least once📚 Asch, 1951
4Narrative TransportationStories reduce counter-arguing📚 Green & Brock, 2000
5Commitment & ConsistencySmall yes → big yes (4.5x increase)📚 Freedman & Fraser, 1966

The Persuasion Sequence

Emotion (System 1) → Decision → Logic (System 2) → Justification

People decide emotionally, then rationalize. Lead with emotion, support with logic.

📚 Kahneman, "Thinking, Fast and Slow" (2011)

Cialdini's 7 Principles of Influence

PrincipleMechanismCopy Application
ReciprocityGive first, receive laterFree value before asking
CommitmentSmall yes leads to big yesMicro-conversions first
Social ProofFollow the crowdTestimonials, user counts
AuthorityTrust expertsCredentials, endorsements
LikingBuy from people we likeRelatable voice
ScarcityLimited = valuableGenuine deadlines only
Unity"One of us"Shared identity

📚 Cialdini, "Influence" (1984), Unity added in "Pre-Suasion" (2016)

Loss Aversion

Losses hurt ~2x more than equivalent gains feel good.

FramingEffectiveness
"Save $100"Good
"Don't lose $100"Better
"Stop wasting $100/month"Best

📚 Kahneman & Tversky, Prospect Theory, Econometrica (1979) — Nobel Prize 2002

Processing Fluency

Easier to process = more believable.

  • Short sentences
  • Simple words
  • High contrast
  • White space

📚 Reber & Schwarz, Consciousness and Cognition (1999)
