Etymology Origin:
The word unbiased emerged in the 17th century by combining the negative prefix un- with bias, which originally referred to a diagonal line in tailoring but shifted metaphorically to mean "partiality." The suffix -ed solidifies its adjectival form, creating a term for impartiality. The evolution reflects a logical progression from literal slanting to figurative fairness.
