A POSTERIORI: A conclusion reached through logical reasoning based on facts and observations about the real world. This notion is closely related to the scientific verification of hypotheses and the identification of principles. A similar sounding, but opposite term is a prior, which is a unverified presumption made before an analysis is undertaken. For example, in the study of economics of crime you might assume, a priori, that people are basically "good", and conclude, a posteriori, that people are more likely to commit crimes when the threat of capture and conviction is lower.

Ordinal utility does not presume that satisfaction is a measurable characteristic of a person, like height or weight, that can be compared against an established benchmark. The contrasting notion is cardinal utility, which is based on a numerical standard.
