What problem does it solve? Marketers often make decisions based on intuition or copy competitors without understanding why customers actually buy. This Skill provides a structured taxonomy of psychological principles and mental models so you can diagnose conversion problems, design persuasive campaigns, and price products based on how people actually think and decide. ## Core Features & Use Cases - Mental Model Library: Covers 60+ models organized by category, including foundational thinking (First Principles, Inversion, Pareto), buyer psychology (Loss Aversion, Social Proof, Anchoring), persuasion (Reciprocity, Scarcity, Commitment), pricing psychology (Charm Pricing, Rule of 100, Decoy Effect), and growth models (Flywheel, Network Effects, Compounding). - Quick Reference Mapping: Matches common marketing challenges like low conversions, price objections, churn, and decision paralysis to the specific models that address them. - Ethical Application Guidance: Each model includes a concrete marketing application with guidance on ethical implementation, distinguishing genuine scarcity from manipulative urgency. - Use Case: When redesigning a pricing page, the Skill recommends anchoring with the highest tier first, applying Good-Better-Best framing, pre-selecting a default plan, and adding social proof near the pricing table. ## Quick Start Ask the AI to apply psychological principles to improve conversions on your pricing page or to explain which mental models fit your current marketing challenge.
