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 problems, understand buyer behavior, and design ethical persuasion strategies grounded in behavioral science. ## 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 (Reciprocity, Scarcity, Foot-in-the-Door), pricing psychology (Charm Pricing, Rule of 100), and growth models (Flywheel Effect, Network Effects). - Quick Reference Mapping: Matches common marketing challenges like low conversions, price objections, churn, and decision paralysis to the relevant psychological models. - Ethical Application Guidance: Each model includes a concrete marketing application with guidance on ethical implementation. - 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 attractive, and add social proof near the call-to-action. ## Quick Start Ask the assistant to explain which psychological principles apply to your marketing challenge, such as improving conversions on a pricing page or designing an onboarding flow.
