Some interest propositions... axioms & principles

Amara's law — "We tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run". Proposed by Roy Amara.

Edwards' law — "You cannot apply a technological solution to a sociological problem."

Goodhart's law — When a measure becomes a target, it ceases to be a good measure.

Gustafson's Law (also known as Gustafson-Barsis' law) is a law in computer engineering which states that any sufficiently large problem can be efficiently parallelized. Coined by John Gustafson in 1988

Hanlon's razor — A corollary of Finagle's law, normally taking the form "Never attribute to malice that which can be adequately explained by stupidity.". As with Finagle, possibly not strictly eponymous.

Hlade's Law — If you have a difficult task, give it to a lazy person; they will find an easier way to do it.

Hofstadter's law — "It always takes longer than you expect, even when you take into account Hofstadter's Law." It was created by Douglas Hofstadter in his book Gödel, Escher, Bach.

Hotelling's law in economics — Under some conditions, it is rational for competitors to make their products as nearly identical as possible.

Hutber's law — "Improvement means deterioration". Coined by financial journalist Patrick Hutber.

Kerckhoffs' principle (also called Kerckhoffs' assumption, axiom or law) was stated by Auguste Kerckhoffs in the 19th century: a cryptosystem should be secure even if everything about the system, except the key, is public knowledge. It was reformulated (perhaps independently) by Claude Shannon as "the enemy knows the system". In that form it is called Shannon's maxim.

Metcalfe's law — In communications and network theory, states that the value of a system grows as approximately the square of the number of users of the system. Framed by Robert Metcalfe (born 1946) in the context of the ethernet.

Occam's razor — States that explanations should never multiply causes without necessity. When two explanations are offered for a phenomenon, the simplest full explanation is preferable. Named after William of Ockham (ca.1285–1349)
