The quality of being trusted and believed because of evidence, track record, expertise, and transparency is called what?

• A. Authority
• B. Trust
• C. Reliability
• D. Credibility

Answer: (D)

Credibility is the quality that makes a source believable and worthy of trust because it is backed by evidence, a solid track record, expertise, and transparency. When someone provides data or sources, demonstrates reproducible results, shows their credentials, and openly shares methods and limits, people have good reason to believe what they’re saying. That combination—evidence plus openness and expertise—is what makes information credible.

Authority relies on a position or title rather than believability of the claims itself. Reliability refers to consistency and dependability in performance or measurement, which can exist without overall believability if the claims aren’t well supported. Trust is the internal feeling of confidence or reliance, while credibility is the external quality of the source that leads people to feel that trust.
