Book Review: Nudge by Richard H. Thaler and Cass R. Sunstein

Nudge explores how small changes in decision-making environments influence behavior. Rooted in behavioral economics, it introduces “choice architecture,” showing how subtle nudges guide people toward better choices without restricting freedom or autonomy, making it easier to act in their best interests.

The authors illustrate how biases affect decisions in finance, health, and policy. Through compelling examples, they show how governments and businesses design systems encouraging beneficial behaviors, like saving for retirement, making healthier choices, or conserving energy. Unlike mandates, nudges make preferred options more accessible and appealing without forcing compliance, ensuring individuals retain control over their decisions.

Nudge is a compelling read for those interested in psychology, economics, or policy. It highlights how small, intentional adjustments can create significant societal and individual improvements, influencing behavior positively in ways that benefit both individuals and the world around them.
