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 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 (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 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 the Rule of 100 to choose between percentage and dollar discounts, and add social proof near the CTA to reduce hesitation. ## Quick Start Ask the agent which psychological principles apply to your marketing challenge, for example: "What mental models should I use to reduce churn in my SaaS onboarding flow?"
