Razor (philosophy) In philosophy, a razor is a principle or rule of thumb that allows one to eliminate (shave off) unlikely explanations for a phenomenon. Razors include: Occam's razor: When faced with competing hypotheses, select the one that makes the fewest assumptions. Do not multiply entities without necessity.
This means that if there are several possible ways that something might have happened, the way that uses the fewest guesses is probably the right one. However, Occam's razor only applies when the simple explanation and complex explanation both work equally well.If a more complex explanation does a better job than a simpler one, then you should use the complex one.
