Description: The Nudge refers to subtly guiding choices and behaviors without restricting options, often used in the ethical design of AI. This concept is based on the idea that human decisions can be positively influenced through the presentation of options and the structure of the environment in which those decisions are made. Instead of imposing restrictions or coercions, the Nudge seeks to facilitate choices that benefit both the individual and society at large. This approach aligns with ethical principles that promote autonomy and freedom of choice, allowing individuals to make informed and responsible decisions. In the context of artificial intelligence, the Nudge is applied in the design of interfaces and algorithms that steer users towards desirable behaviors, such as adopting healthy habits or reducing energy consumption, without eliminating freedom of choice. This method is considered a powerful tool for promoting well-being and sustainability while respecting individuals’ decision-making capacity.
