Difference Between Fact and Opinion


Main Difference

The main difference between Fact and Opinion is that Fact relates to the something true or real, which is confirmed by evidence, documentation, etc. and Opinion is what a person believes or thinks about something.

Fact vs. Opinion

A fact is a thing that can be proven as true by someone else. This truth can test through observation, experimentation, experience or some other means. Opinions are assertions people make about their beliefs and or judgments. They cannot test and verify as facts can. Facts can be verified or proven after standard allusions or scientific experiments whereas opinions are the result of emotion or interpretation of facts, this can be supported by an argument, which can make two opposing opinions from the same set of facts. Fact is objective, and opinion is subjective and personal. Facts are hardcore, and hence they cannot keep constantly changing whereas opinions can vary and not set in stone; they can also change from conviction or circumstances. Facts are also general, and they do not change as per region, cast, culture, religion, etc. and an opinion can influence by culture, religion, society, etc.


Scientific facts generally arise from scientific inferences, an educated think or opinion, created by a person, while it is not a fact until is proven on the other side Opinions can also become facts when proven and believed that almost all facts were opinions before they were proven. A fact is only truth and truth itself whereas opinion is only just a thought or speculation and it can lead to controversies. Facts are strong statements and opinions can be biased statements. Facts always stay back in history. Conversely, opinions are only views that may not get into history.

An opinion is a perspective or judgment about something, i.e., what someone thinks about something. Opinions not necessarily based on facts or knowledge. Opinions are always subjective. Opinions often identified by the use of adjectives, superlatives, comparatives and first-person point of view. e.g., The speed limit should reduce, or everyone respects the principle of our school.

Hence, due to individual differences, every person’s opinion on a particular matter is also different.
