What is the term used for a written document defining expectations of a certain group based on ideas of what is right and what is wrong?

The term that best defines a written document outlining the expectations of a certain group based on notions of right and wrong is a "Code of Ethics." This document serves to guide individuals or organizations in making moral decisions, establishing standards for behavior that align with their values and principles.

A Code of Ethics often addresses various aspects of professional conduct, including integrity, fairness, and respect, ensuring that individuals understand the ethical implications of their actions within their field or organization. It is essential for promoting accountability and fostering an environment of trust and transparency.

While other terms, such as Code of Conduct or Code of Practice, might pertain to standards of behavior or procedures within a specific context, they do not inherently focus on the moral dimensions of right and wrong that are central to a Code of Ethics. Therefore, identifying and adhering to a Code of Ethics is crucial for maintaining ethical integrity in any professional setting.
