Occam’s razor (also Ockham’s razor or Ocham’s razor further known as the law of parsimony is the problem-solving principle that essentially states that “simpler solutions are more likely to be correct than complex ones.” When presented with competing hypotheses to solve a problem, one should select the solution with the fewest assumptions. The idea is attributed to English Franciscan friar William of Ockham (c. 1287–1347), a scholastic philosopher and theologian.

Occam’s Razor, is a classic principle of logic and problem-solving. Instead of wasting your time trying to disprove complex scenarios, you can make decisions more confidently by basing them on the explanation that has the fewest moving parts.
