A value judgment is a judgment of the rightness or wrongness of something, or of the usefulness of something, based on a personal view. As a generalization, a value judgment can refer to a judgment based upon a particular set of values or on a particular value system. A related meaning of value judgment is an expedient evaluation based upon limited information at hand, an evaluation undertaken because a decision must be made on short notice. The term value judgment can be used both in a positive sense, signifying that a judgment must be made taking a value system into account, or in a disparaging sense, signifying a judgment made by personal whim rather than rational, objective thought.
