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, explain 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, 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 Decoy Effect to make the target plan look like the obvious choice, and frame costs with mental accounting ("$1/day" instead of "$30/month"). ## Quick Start Ask the AI to explain which psychological principles apply to your marketing challenge, such as improving conversions on your pricing page.
