Finagle's law

Encyclopedia : F : FI : FIN : Finagle's law

Finagle's Law of Dynamic Negatives (also known as Finagle's corrollary to Murphy's Law) is usually rendered:

Anything that can go wrong, will—at the worst possible moment

One variant (known as O'Toole's Corollary of Finagle's Law) favored among hackers is a takeoff on the second law of thermodynamics (also known as entropy):

The perversity of the Universe tends towards a maximum.

The term "Finagle's Law" was first used by John W. Campbell, Jr., the influential editor of Astounding Science Fiction (later Analog). He used it frequently in his editorials for many years in the 1940s to 1960s but it never came into general usage the way Murphy's Law has.

Eventually the term "Finagle's law" was popularized by science fiction author Larry Niven in several stories depicting a frontier culture of asteroid miners; this "Belter" culture professed a religion and/or running joke involving the worship of the dread god Finagle and his mad prophet Murphy.[link]

Hanlon's Razor (or Hanlon's Law) is a corollary of Finagle's law. Hanlon's Razor says "Never attribute to malice that which can be adequately explained by stupidity."
