Which term refers to an ethical principle that promotes truthful communication?

The correct term that refers to an ethical principle promoting truthful communication is candor. Candor emphasizes the importance of openness and honesty in communication, allowing individuals to express their thoughts and ideas without concealment or deceit. This principle is fundamental in various contexts, such as legal, business, and personal interactions, where clarity and truthfulness are essential for trust and effective functioning.

While integrity focuses on the adherence to moral and ethical principles more broadly and encompasses the notion of honesty, it is not exclusively about communication. Veracity, on the other hand, denotes truthfulness and accuracy but is less commonly used in the context of promoting communication as much as it describes the quality of being truthful. Accountability pertains to the obligation to justify actions and decisions; it is more about responsibility than the act of communicating truthfully. In contrast, candor directly relates to the act of being open and forthcoming in communication, making it the most fitting choice for this question.
