heursistic

Master reference for 88 psychological heuristics — the complete leverage list for sales, copywriting, offer design, cold outreach, objection handling, and persuasion. Use this skill whenever working on any stimulus meant to influence human behaviour: cold emails, DMs, VSL scripts, sales call frameworks, proposal copy, landing pages, CTAs, offer structuring, objection rebuttals, or follow-up sequences. Always trigger when the user asks how to make copy more persuasive, how to handle a specific objection, how to frame an offer, how to structure a pitch, or how to get someone to take action. If the task involves getting a human to do something — consult this skill first, every time, without exception.

Heuristics — 88 Psychological Levers

A full operating system for understanding how humans make decisions and how to craft stimuli that move them to action.

Core Principle

Psychology sets the conditions for what an effective stimulus is. Heuristics are leverageable. Understanding them helps craft stimuli more conducive to action that a human otherwise wouldn't have taken.

These are models of behaviour — not binary rules. Not all apply in every situation. Pick the relevant ones. Don't overdo it (M34).

Priority Rules

Priority	Heuristic	When
Always	#1 Reward/Incentives	Every piece of copy — address the offer/incentive first
Always	#2 Punishment/Risk	Every piece of copy — reverse the risk or they don't act
Live calls	M2 Frame control	Any real-time or direct conversation
Direct interaction	M7 Understanding bias	Any situation where trust must be built fast
Everything else	Pick 3–5 most relevant	Match to stimulus type and target

---

How to Apply — Step by Step

Step 1 — Identify the stimulus type What is being written or designed? (cold email / DM / VSL / sales call script / offer / landing page / CTA / follow-up / objection rebuttal / proposal)

Step 2 — Identify the target Who is this for? What do they want? What do they fear? What's their likely prior experience with similar offers?

Step 3 — Select heuristics From the full list, identify the 3–7 most relevant levers. Always start with #1 (what's the incentive?) and #2 (what's the perceived risk of acting?).

Step 4 — Apply without overdoing Weave the selected heuristics into the stimulus naturally. The output must still feel like a genuine human wrote it. If it reads as slimy or over-engineered, M34 has been violated.

Step 5 — Annotate (optional) If the user wants to understand what's being used and why, annotate each key phrase or section with the heuristic it's activating.

The 88 Heuristics — Inline Summary

Part 1 — The Leverage List (#1–#54)

#1 Reward super-response tendency (incentives) Main driver of human behaviour. People rarely do things without an incentive. Your offer IS the incentive. Better offer = stronger incentive = more action.

#2 Punishment super-response tendency Humans avoid decisions they believe will lead to punishment (lost capital, wasted time, embarrassment). This is why we reverse risk. No risk reversal = they fear punishment and don't act.

#3 Influence from mere association tendency Biased by what something is associated with. Price = quality signal. Authority = result signal. Price below competitors and prospects associate you with lower quality.

#4 Liking/loving tendency More likely to act on something if they like the person asking. People buy from people they like.

#5 Disliking/hating tendency Hate filters everything — even true statements. If someone hates your approach, they won't schedule even if you can change their life.

#6 Doubt avoidance tendency Humans hate sitting with doubt. They make decisions just to escape it — even irrational ones. Slight doubt = they decide NOT to speak with you, just to eliminate the doubt.

#7 Inconsistency avoidance tendency Reluctant to act in ways misaligned with their worldview or self-image. Get a prospect to schedule a call and remind them of that decision — they'll show up.

#8 Commitment consistency (confirmation) bias Seek info that confirms existing perception. Reject what doesn't. Get a "think about it" prospect to pay a deposit. Confirmation bias does the rest.

#9 Curiosity tendency Humans hate having half the picture. They'll act to complete it. Don't give every piece of info. Curiosity keeps the prospect engaged until the call.

#10 Kantian fairness tendency Extremely sensitive to perceived unfairness. "You work hard but don't make money — you don't deserve to suffer like this."

#11 Excessive self-regard Humans believe they are better than others. Overestimate abilities and objectivity. "I've tried everything" = they believe it worked fine and the thing was the problem, not them.

#12 Pain avoiding denial To offset pain, humans enter denial and warp their worldview. Ads flop. They declare the problem was the platform, not them. Expect this in objections.

#13 Overoptimism tendency Expect better outcomes than are rational, overestimate speed of results. Don't be afraid to write "too good to be true" statements.

#14 Deprival super-reaction tendency (loss aversion) Negative emotional weight of loss is ~10× stronger than positive weight of gain. Position as a get-it-or-lose-it deal.

#15 Social proof tendency Base decisions on what other humans do. Stack social proof everywhere.

#16 Contrast misreaction tendency Always compare something to its opposite or anchor. $1,000 seems expensive vs. $45. Cheap vs. $1,000,000. Control the anchor.

#17 Authority misinfluence tendency Assign believability to authority. Build authority via case studies, LinkedIn, platform partnerships.

#18 Cognitive closure Humans like things resolved. Will make decisions just for the sake of closure. Someone decides on a sales call before speaking to their business partner — just to have closure.

#19 Cognitive drift Belief systems change gradually over time with persistent exposure. Someone believes a 1-call close is impossible, then changes their mind after 11 months of evidence.

#20 Cognitive dissonance Struggle to hold two opposing beliefs at once. Resolve through commitment. Once they're in your system, competing views create dissonance — they resolve by committing to you.

#21 Familiarity bias Like, trust, and believe things simply because they are familiar. Most cold email replies come at follow-up 6+. This is also the entire organic distribution thesis.

#22 The Ikea effect Love things they built themselves or ideas they arrived at on their own. Propose ideas collaboratively. Make them feel involved.

#23 Reciprocation tendency Naturally obligated to those who have done them a favour. Give a payment plan "because you like them." They feel obliged to return the favour.

#24 Ben Franklin effect More likely to like and do further favours for people they've already done favours for. Ask a small favour the day before. Or remind them of favours they've already done.

#25 Information bias Wired to seek information before deciding, even when unnecessary. Control what you reveal and when — don't front-load everything.

#26 Action bias Bias towards action. Even if not required, they have an urge to act. If someone replies "we're all set" — respond with "let's see if there are any small improvements."

#27 Non-adaptive choice switching (once bitten, twice shy) Avoid decisions similar to previous ones they regretted. The word "marketing" in your copy triggers every bad agency experience they've had.

#28 Escalation of commitment (sunk cost) Escalate commitment because they've already invested. 60 mins on a call and still hasn't bought = MORE likely to give you 15 more minutes.

#29 Hot-hand fallacy Believe someone is "on a roll" based on recent performance. "The last 3 people to work with us got amazing results." Leverage recency of wins.

#30 Ambiguity effect Avoid uncertainty. Won't act on things they can't clearly understand. If they have to think too hard, they opt out. Make everything unambiguous.

#31 Status quo bias Biased toward conserving current ways of doing things. "Traditional" and "tried and tested" signal respect for the status quo.

#32 Dunning-Kruger effect Lacking skill overestimate competence. "You know what to do" — they feel called out in a flattering way.

#33 Illusory truth effect Perceive claims as truer if previously exposed to them. Repeat your core claim across all stimuli.

#34 Rhyme as reason effect More credence to claims that rhyme. Sounds cheesy. Works anyway.

#35 Subjective validation Find claims more true if they have personal meaning. Cold email describing the exact problems the prospect is facing gets more action.

#36 Scarcity bias Biased toward acquiring scarce things. Cap your offer. Limit how many new clients you take per quarter.

#37 Urgency bias More likely to act if inaction has consequences. "This window closes after [event]. If we don't move now, we miss the opportunity."

#38 Click-whirr conditioning Conditioned, knee-jerk responses to familiar patterns. If your copy looks like every other cold email, it gets reflexively deleted.

#39 Reason respecting tendency More likely to do something if there's a reason — even a weak one. Add "because ___" after every CTA. Any reason increases compliance.

#40 Egocentric bias Rely solely on their own perspective. Think they're always right. Can't attack their idea directly. Use questions and empathy to bypass the ego.

#41 Anchoring bias Rely too heavily on the first piece of information received. Show your high-ticket offer first. Then your lower offer seems cheap by comparison.

#42 Availability mis-weighing tendency Default to the option most available to them. More follow-ups = more available Calendly link = more clicks.

#43 Frequency illusion (Baader-Meinhof) After noticing something first, see it more often and conclude it's more frequent. Once a prospect believes one piece of your social proof, they start seeing it everywhere.

#44 Barnum effect Believe vague, general personality descriptions apply specifically to them. "We love working with hard workers." Even vague praise lands.

#45 Zero risk bias Prefer eliminating risk entirely over better risk-reward ratios. Position your offer as the zero-risk option. Continuing what they're doing is the real risk.

#46 Humour bias Act irrationally based on things that make them laugh. An odd joke lowers guard. Use sparingly.

#47 Hyperbolic discounting Prefer small immediate rewards over larger later ones. Position your offer to produce immediate early wins.

#48 Ostrich effect Bury their heads in the sand when trouble is brewing. "You don't have to worry about it — we've got it." You are the sand.

#49 Groupthink Large groups get swept up in collective irrational thinking. Can be engineered with seeded early signals, then real organic momentum kicks in.

#50 Recency effect Things that come last are remembered most clearly. If a prospect is comparing vendors, be scheduled to pitch last.

#51 Verbatim effect Reduce complex encounters to simple memorable summaries — and decide based on those. What's the one sentence they walk away with? Design for that.

#52 Envy/jealousy tendency Get envious when others obtain things they desire. "Other studios in your space are crushing this — I want to help you do the same."

#53 Facial attention bias Trust faces. Attention biased toward images with faces conveying emotion. Use your face in thumbnails and creative.

#54 First conclusion bias Biased toward the first idea discovered. Show the pricing option you want them to pick first.

Part 2 — Morgan's Heuristics (M1–M34)

M1. Permission-based mis-influence Humans like perceived control. Far more likely to agree if asked for permission first. "Would it be alright if I asked you a couple of questions about your situation?"

M2. Frame-based misreaction Emotional states are contagious. Whoever is most persistent in their frame wins. NEVER enter the prospect's frame of doubt. Set your own frame of extreme confidence and hold it.

M3. Psychological attrition tendency (persistence) Persistence decreases the threshold for action. Never say "this is my last follow-up." Stay persistent until they react.

M4. Graduality tendency Some decisions start as unfathomable, then become entertainable with enough gradual exposure. 11 months of one testimonial per month turned a "no way" into "alright you got me."

M5. Simple digestibility More likely to act on things that are easy to understand. Write copy that a young child could understand.

M6. Relatability bias If they can relate, they're more vulnerable to influence. "If you had a perfect-fit prospect, would you give them the price without attaching value first?"

M7. Understanding bias (THE WEAPON) Humans who feel understood are immediately more likely to trust. Mirror their exact thoughts and emotional state back to them. Especially in objection handling. This is a true weapon.

M8. Originality bias More likely to respond to stimuli that are original. Break through click-whirr conditioning. Don't copy what 10,000 others send.

M9. Creativity bias Respond better to creative entry-level stimuli. Creative follow-ups (memes, unexpected formats) stand out. Must still be effective.

M10. Live up to an expectation bias Crave living up to expectations set by others. "I can tell you're the kind of person who acts when they know something makes sense." Now they have to prove you right.

M11. FOMO bias Hate missing out when others around them are getting it. "The last thing I'd want is for someone else to scoop this who might be a worse fit than you."

M12. Disarming honesty bias Radical transparency disarms scepticism. State a hard truth, then segue into your pitch. They believe the pitch because you built trust with the truth.

M13. Novelty bias (shiny object syndrome) Excited by new, never-seen-before things. Position your service as something they will never have seen or tried before.

M14. Conviction bias Things stated with confidence are more believable regardless of efficacy. "This will completely change how your UA performs" — powerful when delivered with full conviction.

M15. Casual bias Professionals who are casual about their skills are regarded as more authoritative. "You need 20 appointments a month. That's 1 a day. That's nothing — we do 20 a day."

M16. Tried n' tested bias Find trust and comfort in proven, battle-tested approaches. "These methods are rooted in principles that have stood the test of time."

M17. Selfishness tendency Appeal to their interest, not to reason. "If you do this, you keep all of it."

M18. Pattern break bias Inbuilt pattern recognition instantly categorises familiar stimuli as worthless. Your entry-level stimulus must break the expected pattern.

M19. Mystery bias Something shrouded in mystery creates interest and action. "It's actually a bit of a secret — but I'd be happy to share it on a call."

M20. Politeness bias React well to people who treat them with respect. Basic politeness goes a long way. Especially in cold outreach.

M21. Effort perception bias More vulnerable to persuasion from someone who appears to have put in significant effort. A personalised page works because of the PERCEPTION of effort.

M22. Dramaqueen bias Hyperbole is a powerful tool to amplify problems and dreams. Exaggerate the problem to make solving it feel urgent.

M23. Disqualified identity bias Disqualifying people from an offer makes them more likely to think it's for them. "This isn't for people looking for a quick fix." Watch them immediately self-qualify.

M24. Removed self-concerns bias People have identity concerns that hold them back from deciding. Remove the concern preemptively. "You don't need to be a technical expert."

M25. Show n' tell bias People believe what they see more readily than what they're told. Don't tell prospects — show them. Proof beats claims every time.

M26. Lil' bonus bias Often the difference between acting and not is a tiny tipping-point incentive. A small unexpected bonus can break the threshold.

M27. One of a kind bias If they believe they can only get what they need from you, they'll buy from you. "You can't get this anywhere else." Must be backed up with WHY.

M28. Instruction clarity bias Humans like a clear path. Tell them exactly what happens if they act. Spell out the next 3 steps with total clarity. Remove all ambiguity from the CTA.

M29. Exclusivity bias Like acting on things that make something exclusively theirs. "If you work with us, we don't work with anyone directly competing with you."

M30. Hard work bias Business owners overestimate their work ethic. Leverageable. "One hard worker to another."

M31. Trend bias (don't get left behind) Fall prey to trend bias when they think they can capitalise on the next big thing. "We're at the start of a massive trend and I want to get you in early."

M32. Justification bias (why) Like to understand why things work the way they do. Any reason helps. "The reason we do it like that is because it works better."

M33. Quantitative specificity bias Predisposed to believe specific numbers and statistics. "83.3% of our clients" reads as more credible than "most of our clients."

M34. Overdone-it bias (equilibrium warning) Bias leverage taken too far backfires. Reads as slimy and unnatural. Pick 3–5 heuristics. Not 30. The output must still feel like a real human wrote it.

Usage Notes

• #1 and #2 are always in play — address incentive and risk first in every piece of copy
• M7 (understanding bias) is a master key — use it whenever trust must be built
• M2 (frame control) applies on all live or real-time conversations — hold your frame
• The sequence matters: familiarity (#21) before conviction (M14); curiosity (#9) before authority (#17)
• M34 is the ceiling — if it starts to feel engineered or slimy, strip heuristics back
• When annotating copy, label each key phrase with its heuristic number so reasoning is explicit
