What does unbiasedness mean?
Unbiasedness is the noun denoting the quality of judging, reporting, or acting without prejudice, favouritism, or personal preference. It is especially used when describing the fairness of a decision-making process, the neutrality of a reporter, or the impartiality of research. The word has a formal, approving connotation and often conveys that all relevant evidence or competing viewpoints were considered without improper influence. It is normally an uncountable mass noun, so forms such as “an unbiasedness” are uncommon, while a plural is rarely needed. Unbiasedness is closely related in meaning to impartiality, objectivity, fairness, and neutrality, although those terms can emphasize different aspects: impartiality focuses on equal treatment, objectivity on detached or evidence-based assessment, and neutrality on avoiding commitment to one side. The word is useful where the absence of bias is being treated as an important quality or safeguard.

Where does unbiasedness come from?
Unbiasedness was formed in English by adding the noun suffix “-ness” to “unbiased,” which combines the prefix “un-” with “bias.” Bias entered English from Middle French biais, originally meaning “oblique” or “slanting” and used in contexts such as oblique lines; its more remote origin is uncertain. The later sense of bias as prejudice or favouritism developed from the earlier idea of deviation from a straight or balanced course.
