What problem does it solve? Teams often write landing pages, onboarding flows, and sales copy that rely on guesswork rather than established persuasion science, resulting in weak conversion and trust signals. This Skill provides a structured framework for applying the seven principles of ethical persuasion to product and marketing decisions. ## Core Features & Use Cases - Seven-Principle Framework: Covers reciprocity, commitment and consistency, social proof, authority, liking, scarcity, and unity, each with product application tables and copy patterns. - Scoring and Diagnostic System: Scores persuasive elements on a 10-point scale with a quick diagnostic checklist and an ethics gate that caps deceptive tactics. - Deep Reference Library: Includes per-principle references, copywriting templates, real-world case studies (Dropbox, Airbnb, Amazon, Duolingo, Apple), and an ethics guide covering FTC, GDPR, and dark-pattern regulations. - Use Case: When redesigning a SaaS landing page, run the Quick Diagnostic to identify which principles are missing, then layer social proof, authority, and reciprocity using the provided copy patterns and verify the result passes the transparency test. ## Quick Start Ask the assistant to audit your landing page or signup flow using the influence psychology framework and score it against the seven persuasion principles.
