What problem does it solve? Marketers often guess why customers buy or fail to convert. This Skill provides a structured library of psychological principles and mental models so you can diagnose behavior, design persuasive campaigns, and make decisions 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 (Anchoring, Loss Aversion, Social Proof), persuasion techniques, pricing psychology, and growth models, each with a concrete marketing application. - Quick Reference Mapping: A challenge-to-model table maps common problems like low conversions, price objections, and churn to the relevant psychological principles. - Ethical Application Guidance: Each model includes implementation suggestions focused on ethical influence rather than manipulation. - Use Case: When your landing page converts poorly, consult the Skill to identify that Hick's Law and Activation Energy may be the issue, then simplify choices and reduce starting friction. ## Quick Start Ask the AI to analyze why your trial signup page has low conversions using marketing psychology principles and recommend fixes.
