A PRIORI: A presumption made before an analysis is undertaken, often based on experiences, beliefs, or deductions from seemingly self-evident propositions about how the world works. This is a Latin for assumption or axiom. A similar sounding, but opposite term is a posteriori, which is derived from observation or facts. For example, in the study of economics of crime you might assume, a priori, that people are basically "good", because that just seems to be part of human nature, and conclude, a posteriori, that people are more likely to commit crimes when the threat of capture and conviction is lower.
