What is an Actuary?

According to Kathleen C. Miller, an actuary is a real flesh and blood person who "passes as an expert on the basis of a prolific ability to produce an infinite variety of incomprehensive figures calculated with micrometric precision from the vaguest of assumptions based on debatable evidence from inconclusive data derived by persons of questionable reliability for the sole purpose of confusing an already hopelessly befuddled group of persons who never read the statistics anyway!"
