What problem does it solve? Marketers often guess at why customers buy or fail to convert. This Skill provides a structured taxonomy of psychological principles and mental models so you can diagnose behavior, design ethical persuasion, and make better marketing decisions grounded in behavioral science. ## Core Features & Use Cases - Mental Model Library: Covers foundational thinking models (First Principles, Inversion, Pareto), buyer psychology (Anchoring, Social Proof, Loss Aversion), persuasion frameworks (Reciprocity, Scarcity, Cialdini-style principles), pricing psychology (Charm Pricing, Rule of 100), and growth models (Flywheel, Network Effects). - Quick Reference Mapping: A challenge-to-model table maps common problems like low conversions, price objections, churn, and decision paralysis to the relevant psychological principles. - Use Case: When redesigning a pricing page, apply anchoring by showing the highest tier first, use Good-Better-Best framing to make the middle tier the obvious choice, and add social proof near the CTA to reduce purchase anxiety. ## Quick Start Ask the assistant to apply marketing psychology principles to improve conversions on your pricing page or onboarding flow.
