A philosophical or scientific principle according to which the best explanation of an event is the one that is the simplest, using the fewest assumptions or hypotheses.
The definition of Occam's Razor is the idea that the most likely explanation for an event is usually the simplest explanation.
An example of Occam's Razor is all the leaves falling off a tree because it's Autumn.
A rule in science and philosophy stating that entities should not be multiplied needlessly. This rule is interpreted to mean that the simplest of two or more competing theories is preferable and that an explanation for unknown phenomena should first be attempted in terms of what is already known. Occam's razor is named after the deviser of the rule, English philosopher and theologian William of Ockham (1285?–1349?).
(sciences) The principle of preferring the simpler of two competing theories.
