🧠 Psychology of Money
Nudge
How small changes in how choices are presented can improve decisions.
Read the summary ↓Summary — what Nudge is about
Thaler and Sunstein introduce 'choice architecture': the way options are presented dramatically affects what people choose. A well-designed 'nudge' can steer people toward better outcomes without restricting freedom.
The book shows how defaults, framing and simple design can improve decisions in saving, investing, health and more — a philosophy they call 'libertarian paternalism'.
Key lessons & takeaways
- Defaults are powerful — most people stick with them.
- How choices are framed changes what people pick.
- Good 'choice architecture' improves outcomes gently.
- Automatic enrolment dramatically raises saving rates.
- You can guide behaviour without removing freedom.
