Persuasive design applies behavioral psychology principles to influence user decisions and behaviors. When used ethically, these patterns can help users achieve their goals while supporting business objectives.
Key Persuasive Design Frameworks
- Fogg Behavior Model: Motivation + Ability + Trigger
- Cialdini's Six Principles: Reciprocity, commitment, social proof, authority, liking, scarcity
- Hook Model: Trigger → Action → Variable Reward → Investment
- Prospect Theory: How users evaluate potential losses and gains
Ethical Persuasion Patterns
- Social proof: Showing others' positive experiences
- Commitment and consistency: Small steps before larger ones
- Loss aversion: Framing to prevent negative outcomes
- Anchoring: Reference points for decision-making
- Scarcity: Communicating limited availability when real
- Authority: Expert guidance and recommendations
- Unity: Creating shared identity and belonging
- Reciprocity: Providing value before requesting action
Implementation Guidelines
- Align persuasion with user goals and values
- Be transparent about persuasive techniques
- Avoid exploiting vulnerabilities or creating false urgency
- Measure both conversion and user satisfaction
- Test patterns with diverse user groups

The Difference Between Persuasion and Manipulation
- Transparency vs. deception
- User benefit vs. user exploitation
- Informed choice vs. limited options
