Spotting Facts and Opinions

Introduction

Read these two sentences:

1. "London is the capital of England."
2. "London is the best city in the world."

They look similar, don't they? Both are about London. Both sound confident. But there's a crucial difference: the first is a fact — it can be checked and proved. The second is an opinion — it's someone's personal view.

Being able to tell the difference between facts and opinions is one of the most important critical thinking skills you'll need for the FSCE 11+ exam. In comprehension passages, you'll need to work out which parts are factual information and which parts are the writer's opinion. In this lesson, you'll learn exactly how to do that.

What Is a Fact?

A fact is a statement that can be proved to be true or false. It doesn't matter whether you agree with it — what matters is that it can be checked.

Examples of facts:

• Water boils at 100°C at sea level.
• There are 26 letters in the English alphabet.
• The Great Fire of London started in 1666.
• Mount Everest is 8,849 metres tall.

Even a wrong statement can be a factual claim. "There are 30 letters in the English alphabet" is a factual statement — it's just a false one. The point is that it can be checked.

What Is an Opinion?

An opinion is a personal belief, view, or judgement. It cannot be proved true or false because different people may reasonably disagree.

Examples of opinions:

• Chocolate ice cream is the tastiest flavour.
• Art is more important than science.
• The book was boring.
• Football is the best sport.

Clue Words for Opinions

Opinions often (but not always) contain words like:

• Judgement words: best, worst, beautiful, ugly, boring, exciting, important
• Belief words: I think, I believe, in my view, it seems, arguably
• Should/ought words: should, ought to, must (when expressing duty rather than certainty)

Tricky Cases

Some statements look like facts but are actually opinions:

• "Shakespeare is the greatest writer in the English language." — This sounds factual, but "greatest" is a judgement.
• "Everyone knows that dogs are better pets than cats." — Starting with "everyone knows" doesn't make it a fact.

Some statements look like opinions but are actually facts:

• "Scientists believe that the universe is approximately 13.8 billion years old." — This is a fact about what scientists believe, even though it reports a belief.

Worked Examples

Worked Example 1: Sorting Statements

Sort these statements into facts and opinions:

Statement	Fact or Opinion?	Why?
"The River Thames flows through London."	Fact	Can be verified on a map
"The River Thames is the most beautiful river in England."	Opinion	"Most beautiful" is a personal judgement
"Queen Victoria reigned for 63 years."	Fact	Can be checked in history records
"Queen Victoria was the best monarch Britain ever had."	Opinion	"Best" is a personal judgement
"Over 8 million people live in London."	Fact	Can be checked with census data
"London is too crowded."	Opinion	"Too crowded" is a personal judgement — some people may disagree

Worked Example 2: Spotting Facts and Opinions in a Passage

Passage: "The Amazon rainforest covers approximately 5.5 million square kilometres. It is the most important ecosystem on Earth. The rainforest is home to around 10% of all species on the planet. Sadly, deforestation is destroying this precious habitat at an alarming rate. Between 2001 and 2020, the Amazon lost approximately 8% of its forest cover."

Analysis:

• "covers approximately 5.5 million square kilometres" — Fact (measurable, can be checked)
• "the most important ecosystem on Earth" — Opinion (a judgement — others might argue oceans are more important)
• "home to around 10% of all species" — Fact (can be checked with scientific data)
• "Sadly" — Opinion signal (this word shows the writer's emotional view)
• "precious" — Opinion signal (a value judgement)
• "alarming rate" — Opinion (what one person finds alarming, another might not)
• "lost approximately 8% of its forest cover" — Fact (measurable, can be checked)

Worked Example 3: Why This Matters in Comprehension

Question: "The writer says the rainforest is 'the most important ecosystem on Earth.' Is this a fact or an opinion? How can you tell?"
