What is the term used to describe the degree of openness a person has in dealings with others?

The term that best describes the degree of openness a person has in dealings with others is responsiveness. Responsiveness refers to how receptive and accepting an individual is in communication and interaction with others, showcasing their ability to listen, engage, and react positively to input or feedback. A highly responsive person typically fosters open dialogue and creates a more inviting environment for collaboration and sharing of ideas.

While assertiveness involves confidently expressing one's opinions or needs, it does not necessarily focus on the openness aspect of interactions. Relativeness, on the other hand, is not a commonly recognized term in the context of interpersonal skills and does not adequately convey the concept of openness. Expressiveness relates more to the ability to convey emotions and thoughts effectively but does not fully encapsulate the degree of openness in dealing with others. Hence, responsiveness is the most fitting term in this context.
