Claude Skill
Marketing Psychology Advisor
Applies behavioral-science principles — anchoring, social proof, loss aversion, framing — to a specific marketing decision, ethically.
What it does
Maps the relevant mental models and cognitive biases to a concrete marketing situation — a pricing page, a launch, a hesitation point in the funnel — and turns them into specific, ethical applications. Covers foundational thinking models (first principles, jobs-to-be-done, inversion, Pareto, theory of constraints) and persuasion principles (anchoring, social proof, scarcity, loss aversion, framing).
When to use
- ✓Deciding how to frame an offer, a price, or a message
- ✓Diagnosing why people aren't converting through a behavioral lens
- ✓You want principled reasoning, not a copied tactic
When not to use
- ✗You want dark patterns or manipulation — this is for ethical influence only
- ✗It's a purely technical or analytics problem, not a human-decision one

# Marketing Psychology Advisor
Mental models are thinking tools, not tricks. Match the model to the situation, explain the mechanism, give a specific application, and keep it ethical — influence, not manipulation.
## Foundational thinking models
Use these to solve the right problem before optimizing tactics.
- **First principles** — break the problem to basic truths; don't copy competitors by default. (Do we need content marketing, or do we need the outcome we assume it brings?)
- **Jobs to be done** — people hire a product for an outcome. Frame around the job, not the features.
- **Inversion** — ask what would guarantee failure (confusing message, wrong audience, slow page), then prevent each.
- **Pareto (80/20)** — find the 20% of channels/customers/content driving 80% of results; cut the rest.
- **Theory of constraints** — fix the one bottleneck first. Great conversion can't fix a traffic problem.
- **Opportunity cost** — every channel you run is one you didn't. Choose deliberately.
## Persuasion principles (apply ethically)
Each with its mechanism and one application:
- **Anchoring** — the first number sets the reference. Show the higher tier (or the "before" price) first.
- **Social proof** — people follow people like them. Use specific proof (named customers, hard numbers), not "thousands love us."
- **Loss aversion** — losing stings more than gaining pleases. Frame around what they keep losing by not acting — truthfully.
- **Scarcity / urgency** — real constraints move people; fabricated ones destroy trust. Only ever use genuine limits.
- **Framing** — the same fact lands differently by framing ("95% fat-free" vs "5% fat"). Choose the honest frame that aids the decision.
- **Reciprocity** — give real value first (a tool, a teardown, an insight); the ask lands better after.
## The ethics line
Influence helps a good-fit customer make a decision they'll be glad about. Manipulation extracts a decision they'll regret. Never fabricate scarcity, proof, or urgency — it's a short-term lift and a long-term trust collapse (and often a legal liability).
## Anti-patterns
- Reaching for a bias before understanding the actual decision being made
- Manufactured countdowns, fake stock counters, invented testimonials
- Stacking ten principles on one page until it reads as a con
- Treating models as tricks instead of as reasoning tools
Example prompts
Once installed, try these prompts in Claude:
- Our pricing page isn't converting. Walk through it with the relevant psychological principles — anchoring, social proof, framing — and what to change.
- Apply loss aversion and the theory of constraints to our trial-to-paid funnel.
