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 60+ models across thinking frameworks, buyer psychology, persuasion, pricing psychology, design, and growth, each with a concrete marketing application. - Quick Reference Mapping: Matches common challenges (low conversions, price objections, churn, decision paralysis) to the relevant models so you can find the right lens fast. - Ethical Persuasion Guidance: Distinguishes legitimate applications from manipulative tactics, such as real scarcity versus fake countdown timers. - Use Case: A B2B SaaS team with three pricing tiers asks how to improve plan selection. The Skill applies anchoring, the decoy effect, Good-Better-Best framing, and the default effect to recommend concrete pricing page changes. ## Quick Start Ask the assistant to apply psychological principles to improve conversions on your pricing page or onboarding flow.
