What is the term used to describe integrity and straightforwardness in one's conduct?

The term that best describes integrity and straightforwardness in one's conduct is honesty. Honesty is fundamentally about being truthful and maintaining strong ethical principles in both personal and professional interactions. It signifies not only the absence of deceit but also a commitment to communicating in a truthful and sincere manner, fostering trust and credibility in relationships.

Loyalty, while important, refers more to a commitment or allegiance to a person, group, or cause rather than a measure of ethical conduct. Transparency involves openness in communication and operations, which can align with honesty but does not fully encapsulate the essence of straightforwardness and integrity on an individual level. Accountability pertains to taking responsibility for one's actions and decisions, which is related to integrity but does not specifically emphasize the trait of being honest.
