- Designing choices and defaults works big time: changing systems like automatic enrollment in pensions can produce huge, lasting effects, while simple wording changes and social comparisons give smaller but very cost-effective boosts.
- There are big practical and political limits to nudging: nudge teams often can only persuade rather than redesign systems, and deliberate "sludge" or gamified interfaces can harm people while current political trends make evidence-based reforms harder.
- Behavioural economics has uncovered many real anomalies and useful tools (like mental accounting), but it hasn’t replaced standard economic theory or textbooks and probably won’t offer a single grand theory; its strength is adding realistic, descriptive insights to existing models.
