What problem does it solve? Marketers often guess at why customers buy or fail to convert. This Skill provides a structured library of psychological principles, cognitive biases, and mental models so you can diagnose marketing problems, understand buyer behavior, 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 Diagnosis: A challenge-to-model mapping table helps you match problems like low conversions, price objections, churn, or decision paralysis to the relevant psychological principles. - Use Case: When your landing page converts poorly, use the Skill to identify applicable models such as Hick's Law, Activation Energy, and the BJ Fogg Behavior Model, then redesign the page to reduce friction and clarify the call to action. ## Quick Start Ask the AI to analyze your landing page or campaign using marketing psychology principles and recommend which mental models apply to your conversion problem.
