Fair, just, equitable, impartial, unbiased, dispassionate, uncolored, objective are comparable when they are applied to judgments or to judges or to acts resulting from or involving a judgment and mean free from undue or improper influence.
Fair, the most general term, implies the disposition or the intention to regard other persons or things without reference to one’s own interests, feelings, or prejudices, often even to the point of conceding every reasonable claim of the weaker side or of giving oneself or the stronger side no undue advantage.
Just implies no divergence from the standard or measure of what has been determined or is accepted as right, true, or lawful and dealings that are exactly in accordance with those determinations, no matter what one’s personal inclinations or interests may be or what considerations in favor of the person or thing judged may be adduced.
Equitable implies a freer and less rigid standard than just, often the one which guides a court of equity as distinguished from a court of law and which provides relief where rigid adherence to the law would make for unfairness.
More often the word implies fair and equal treatment of all concerned.
Impartial implies absence of favor for or absence of prejudice against one person, party, or side more than the other.
Unbiased expresses even more strongly the absence of all prejudice or prepossession and a disposition to be fair to all.
Dispassionate implies freedom from the influence of passion or strong feeling, often also implying great temperateness or even coldness in judgment.
Uncolored (see also COLORLESS ) implies freedom from influences (as personal feeling or a desire to embellish) that would affect the truth or accuracy of an account, a statement, or a judgment.
Objective implies a tendency to view events or phenomena as apart from oneself and therefore to be judged on purely factual bases and without reference to one’s personal feelings, prejudices, opinions, or interests.
