Of parsimony

[Magaret]

The Principle of parsimony infers that a phenomena can be explained best with the simplest [hypothesis] that accounts for all the evidence. Since we can only tell the difference between something that is true and something that is false, by inferring our own observations and using the general rule to make a guess, adding entities to a hypothesis that are not accounted for by evidence results in a hypothesis that is not [parsimonious] and less believable than prior.
This is referred to and explained in [Occams Razor], which follows the same basic principle.
The word may also be used to infer simplicity, or the state of a hypothesis in which it explains a phenomenon using entities suggested by evidence, and no absolutely more.
