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.

SIXTH RULE OF IGNORANCE: The sixth of seven basic rules of the economy. It is a fact of life that obtaining information is a costly activity, it requires resources that have alternative uses. As such, no one knows everything and everyone is ignorant about something. I might know a lot about economics, but you can recite every line of every episode of "Gilligan's Island", and that weird-looking guy you bumped into at the store has a detailed account of everything you've done for the past five years.

[What's This?]
