Occam's razor is a philosophical and methodological principle that suggests that when presented with competing hypotheses or explanations for the same phenomenon, one should favor the one that makes the fewest assumptions. It is often paraphrased as "entities should not be multiplied beyond necessity" or "the simplest explanation is usually the best." The principle is named after the 14th-century Franciscan friar and philosopher William of Ockham, who emphasized simplicity in reasoning.
