Decision architecture is interface design that shapes users' choices and is based on behavioral economics principles.
Effective decision architecture techniques:
- Default Options: Set the desired behavior as the default (80% effective)
- Option Reduction: Too many options lead to decision paralysis (3-5 options is optimal)
- Decision Hierarchy: Present important decisions first, details later
- Framing Effect: Positive frames like 'y chance of winning' instead of 'x risk of losing'
- Progress Indicators: The feeling of completion provides motivation
- Social Proof: Guides such as 'Other users typically chose this'
Caution: Use decision architecture for user benefit, not manipulation. Ethical design builds long-term user trust.
