What is a Fact

A fact can be defined as a thing that is known or proved to be true. Fact can also refer to a piece of information presented as having objective reality. Fact can always be verified with proof or evidence. Facts are always objective and neutral. Given below are some examples of facts:

2008 Summer Olympics was held in China.

Oxygen is used in cellular respiration.

Sun rises from the east and sets from the west.

Autumn comes after summer.

Cast iron is an alloy made of Iron and Carbon.

You can observe that all these facts can be verified or proved by concrete facts. Some of them have been proved by scientific research whereas the general facts can be proven by records and data.

It is also important to note that facts can sometimes be influenced by opinions and biases, even in some academic and research fields. Thus, facts which are influenced by opinions are not objective.

What is an Opinion

An opinion is a view or judgment about something, i.e., what someone thinks about something. Opinions are not necessarily based on facts or knowledge. Since they are personal interpretations based on an individual’s knowledge and experience, they cannot be verified with concrete evidence. Opinions are always subjective.

When you are reading a text, it is always important to distinguish the difference between facts and opinions. Opinions can often be identified by the use of adjectives, superlatives, comparatives and first person point of view. Given below are some examples of opinions.

Dogs are better than cats.

Madrid is the best city in the world.

I think your answer is wrong.

The speed limit should be reduced.  

Everyone respects the principle of our school.

However, it is not always so easy to identify the difference between facts and opinions. For example, you can say that college A is better than college B. This is generally considered as an opinion. However, if you use evidence like survey results, ratings, comparison of facilities, etc. you may be able to present it as a fact.
