[ ok–uhmz rey-zer ]Where did Occamâs razor come from?
Occamâs razor is grounded in the idea of parsimonyâbeing thrifty with your resources. Just as we all strive to pinch our pennies, Occamâs razor teaches us that we should hold off on our hypotheticals.
The phrase Occamâs razor is recorded in 1852 by the Scottish metaphysician Sir William Hamilton. Hamilton credited William of Ockham, a 14th-century English monk and philosopher, with formulating his namesake, Occamâs razor: âMore things should not be used than are necessary.â In other words, when trying to make sense of some phenomenon (especially between two competing alternatives), itâs best to avoid the more elaborate explanationâshave it off, like a razor.
If it looks like a duck, swims like a duck, and quacks like a duck, says Occamâs razor, itâs probably a duck. Not a goose disguised as a duck that infiltrated the flock. Sure, that hypothetical exists. We canât 100% rule out that it didnât happen. But itâs most likely a duck.
Many folks first encounter Occamâs razor in school when learning about the scientific method and learning about how to create testable and falsifiable hypotheses. Occamâs razor compels us to form the simplest hypothesis that is consistent with the data available.
The principle is also commonly applied in modes of reasoning in philosophy, math, and religionâand, of course, The Simpsons in 1994, when Lisa cites Occamâs razor to dismiss some outlandish hypotheticals.
Some critics of Occamâs razor, however, state that the principle is an oversimplification of the complexities of real life and often rules out creative thinking.
How to use the phrase Occamâs razor
Outside of discussions in science and logic, some people casually cite Occam’s razor as a handy rule of thumb to make sense of life and all its messes. Others apply it more sharply to politics, especially to bust conspiratorial thinking.
