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.
Occam's razor is the process of paring down information to make finding the truth easier. In science, it is getting rid of all the assumptions that make no difference to the predictions of the hypothesis. If you have a few hypotheses that could explain an observation, it is usually best to start with the simplest one.oo many 'ifs' is a sign that a statement needs 'Occamizing' and clarifying. Therefore, using Occam's razor, the NASA argument should be regarded as correct. This is not the same as saying that it is proved, only that it is best to investigate the simplest theory first.
