Line 1:
Line 1: − + − − − ==Examples== − If you are walking down a country lane in New England and hear the sound of hooves behind you, you should assume that there is a horse behind you. There are other possibilities, for example zebras and unicorns, but both require more assumptions than a horse. − − In the former case, one must assume that a zebra has escaped from a zoo (a vanishingly rare occurence) or been imported from Southern Africa by a mad millionaire, or some other unlikely scenario. − − In the case of the unicorn, one must assume that unicorns exist - since there are no confirmed sightings of unicorns in the whole of written history, this is a huge assumption. There are many further assumptions to be made concerning, for example, how unicorns managed to breed unnoticed in New England. − − Therefore, since the conclusion that the sound of the hooves is made by a horse requires the fewest assumptions, it is the most reasonable to assume. − − ==Notes and references== − <references/> − − [[Category:Science]]

Occam's Razor is the philosophical principle that, all things being equal, the answer with the fewest assumptions is usually the right one (often refered to as the "simplest" solution).<ref>http://skepdic.com/occam.html</ref> However many scholars have disputed over the definition of "simplest". Some suggest "simplest" means the shortest possible description (called [[Kolmogorov complexity]]); other suggest that it means the description with on average shortest word length.{{fact}} Still others have argued that the simplest model is the one which makes the most precise predictions with the fewest assumptions.
