What does nudge theory rely on?

Nudge theory is grounded in the principles of behavioral science, focusing on how subtle changes in the environment or context can influence people's decision-making processes without coercion. This approach recognizes that individuals often react to various stimuli in ways that do not always align with their best interests or long-term goals. By applying insights from behavioral science, nudges can be designed to guide individuals toward making better choices, whether in health, finance, or general behavior, without restricting their freedom of choice.

For instance, a common application of nudge theory is placing healthy food options at eye level in a cafeteria to encourage better dietary choices. This example illustrates how a thoughtful design of the environment can lead people to naturally gravitate towards more beneficial options without overt pressure or extensive persuasion tactics.

While other options may involve different strategies—such as regulations imposing strict rules, marketing efforts aimed at persuasion, or financial incentives encouraging specific behaviors—they do not embody the non-intrusive, subtle encouragement that is central to nudge theory.
