  1. unacceptable

    Acceptability is the characteristic of a thing being subject to acceptance for some purpose. A thing is acceptable if it is sufficient to serve the purpose for which it is provided, even if it is far less usable for this purpose than the ideal example. A thing is unacceptable (or has the characteristic of unacceptability) if it deviates so far from the ideal that it is no longer sufficient to serve the desired purpose, or if it goes against that purpose. Acceptability is an amorphous concept, being both highly subjective and circumstantial; a thing may be acceptable to one evaluator and unacceptable to another, or unacceptable for one purpose but acceptable for another. Furthermore, acceptability is not necessarily a logical or consistent exercise. A thing may be sufficient to serve a particular purpose but in the subjective view of the decision maker be unacceptable for that purpose.: 6  Philosopher Alex Michalos writes that "[t]he concept of acceptability is as ambiguous and troublesome as probability, confirmation, belief, justice, etc.", and assigns two potential meanings to the term with respect to the possible acceptability of hypotheses. Acceptability is a fundamental concept in numerous fields, including economics, medicine, linguistics, and biometrics.
