Philosophy EthicsFacts, Opinions, and Value Judgments: Knowing What Kind of Claim You're Making
Sage the wise owl perches at a wooden sorting desk under warm lantern light, holding up three labeled cards and gently dropping written claims into three glowing baskets.
- Define the three kinds of claims: factual claims, opinions (preferences), and value judgments.
- Classify a given statement as a factual claim, an opinion, or a value judgment.
- Explain why factual claims can be checked against evidence while opinions are not objectively true or false for everyone.
- Identify the kind of a claim first before deciding how to argue about it.
Key terms
- factual claim
- a statement about how the world is that can be checked against evidence
- opinion
- a personal report of what someone likes or prefers, not true or false for everyone
- value judgment
- a claim that an action or thing is good, bad, right, or wrong
- evidence
- observations, measurements, or records used to confirm or disconfirm a factual claim
Three Baskets, Three Responses
The reason to sort a claim before arguing is that each kind calls for a completely different response. A factual claim invites you to look for evidence — count, measure, test, or look it up. An opinion invites no proof at all, because preferences simply differ from person to person and no one is wrong for liking rainy days. A value judgment invites reasons grounded in shared standards, because it claims something stronger than personal taste. Mixing these up leads to endless arguments about the wrong thing.
Why Value Judgments Are Not Just Opinions
Value judgments feel personal, which is why people often confuse them with opinions, but they make a different kind of claim. Saying 'cheating is wrong' is not like saying 'I dislike broccoli.' A value judgment is meant to apply to an action and can be challenged or defended with reasons, while an opinion only reports private taste. This is why we expect people to justify value judgments — and why we do not demand anyone justify simply enjoying soccer.
Worked examples
Classify and respond to: 'Our team scored more points, so we played better.'
- Separate the two parts: 'our team scored more points' and 'we played better.'
- Test the first part: scoring can be counted from the record, so it is a factual claim.
- Test the second part: 'played better' judges quality, which goes beyond the score, so it is a value judgment.
- Match each to its response: verify the score with evidence, and ask for reasons supporting the quality claim.
Answer: The sentence mixes a factual claim with a value judgment; sorting them first shows you should check the score against the record while asking for reasons before accepting that the team genuinely played better.
Activity
Sort each statement into the correct basket: factual claim, opinion, or value judgment.
Practice
Sort 'this museum has five floors' into the correct basket and explain how you decided.
Explain why you cannot prove someone wrong for saying they enjoy winter the most.
Common mistakes to avoid
- A value judgment is just an opinionA value judgment applies to an action and can be defended with reasons, while an opinion only reports private taste.
- Every claim is really a factOpinions and value judgments are different kinds of claims; many statements cannot be settled by evidence alone.
Check your understanding
Which statement is a factual claim that can be checked against evidence?
Someone says, 'Spinach tastes disgusting.' What kind of claim is this?
A friend says, 'Helping a lost child find their parent is the right thing to do.' What kind of claim is this?
Why should you decide what KIND of claim you are dealing with before you argue about it?
Recap
Claims come in three kinds: factual claims you can check with evidence, opinions that report personal preference, and value judgments about right and wrong. Identifying the kind first tells you how to respond and saves you from arguing about the wrong thing.
