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 marketing challenges and design campaigns grounded in behavioral science rather than intuition. ## Core Features & Use Cases - Mental Model Library: Covers foundational thinking models (First Principles, Inversion, Pareto Principle), buyer psychology (Loss Aversion, Social Proof, Anchoring), persuasion techniques, pricing psychology, and growth models, each with a concrete marketing application. - Quick Reference Mapping: A challenge-to-model table links 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 call to action. ## Quick Start Ask the AI which psychological principles apply to your marketing challenge, such as improving conversions on a pricing page or designing an onboarding flow.
