Difference between fact and opinion. An opinion is somebody who has their own idea about something and what they think about a certain situation or idea. E.g. “I thought the dress looked awful while my friend thought it was very pretty and looked lovely.” It’s showing two very different thoughts about something because it has two very different opinions. Other times it’s when we see things from a very different perspective that give us other opinions. A fact is a true piece of information that we know is right from experience or because the information is right in front of us. A fact can’t be wrong but it is always right that is why it is called a fact. Imagine somebody is sitting down on a chair. It’s a fact that this person is sitting on the chair because the evidence is right in front of us and also because it’s the truth. A person saying that football is rubbish is an opinion but if someone says that a man has landed on the moon it is a fact because a many people have landed on the moon before.
