ockham's razor
C1/C2Formal, Academic, Technical
Definition
Meaning
A principle of problem-solving which states that, among competing hypotheses, the one with the fewest assumptions should be selected.
A general heuristic or rule of thumb for reasoning that simpler explanations are more likely to be correct than complex ones. It is often invoked in scientific, philosophical, and logical discourse to advocate for parsimony and avoid unnecessary complexity.
Linguistics
Semantic Notes
Also correctly spelled 'Occam's razor'. It is a methodological principle, not a scientific law. It does not prove that the simplest explanation is true, but rather suggests it is the most pragmatic starting point for investigation.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'razor' literally as 'бритва' in isolation, as it loses the philosophical meaning. Use 'бритва Оккама' as the established term.
- The principle is about assumptions, not just 'simple' things. A 'simple' explanation may still be complex if it requires fewer new assumptions.
Common Mistakes
- Using it as a synonym for 'the simplest answer is always right'. It's about the fewest *assumptions*, not absolute simplicity.
- Spelling it as 'Ockham's *raiser*' or 'Ockham's *razar*'.
- Using it to dismiss complex but necessary explanations that are well-supported by evidence.

FAQ
Frequently Asked Questions
Both are correct. 'Ockham' is the modern spelling of the village William of Ockham came from. 'Occam' is the Latinised version. 'Occam's' is more common in contemporary use, especially in American English.
No. It is a guideline, not a rule of nature. It suggests that, all else being equal, the explanation requiring the fewest new or ad hoc assumptions is preferable and more likely to be correct. A complex explanation can still be right if it has strong evidence.
The principle is attributed to the 14th-century English Franciscan friar and scholastic philosopher William of Ockham. However, similar ideas were expressed by earlier philosophers.
It is primarily used in philosophy of science, logic, and theoretical science (physics, biology). It is also applicable in fields like medicine (diagnosis), detective work, software development, and any domain involving problem-solving and hypothesis formation.
