Spotting Opinions in Writing: A Smoking Cessation Case Study

Every professional document you write will eventually be read by someone deciding whether to trust it. A report that mixes personal judgment with verified information quietly loses that trust. This is why one of the most valuable skills in business writing is the ability to spot an opinion hiding inside a sentence that looks factual. To make this concrete, we will work through a short paragraph about two new smoking cessation methods, identify the opinions buried in it, locate its topic sentence, recognise how it is built, and finally rewrite it in plain factual language fit for a workplace report.

What separates a fact from an opinion 🔗

A fact is a statement that can be checked against objective proof, such as physical evidence, an eyewitness account, or the result of an accepted method of measurement. An opinion is an interpretation, a value judgment, or a belief that cannot be proved or disproved. The simplest test is to ask a single question of any sentence: can this be verified? If the honest answer is no, you are looking at an opinion, no matter how confident the sentence sounds.

The reason this matters is that the two are constantly placed side by side by writers, often within the same sentence. A fact relies on observation or research and is an objective reality. An opinion is shaped by a person’s feelings, experiences, and values, which is exactly why two reasonable people can hold opposite opinions about the same situation. Sorting one from the other is a core act of critical reading, and it is the foundation of writing that other people can rely on.

The clue words that signal a judgment 🔗

Opinions tend to announce themselves through specific language. Watch for qualifiers that hedge a claim, such as seems, might, may, and appears. Watch also for absolutes like always, never, best, and worst, along with verbs of belief such as think and feel. These are often described as clue words because they reveal a writer’s attitude rather than a measurable reality. Facts, by contrast, tend to carry numbers, dates, quantities, and specific named details that another person could independently confirm.

The case study: two new ways to kick that killer habit 🔗

Imagine a short paragraph that opens with a headline-style line about two new ways to kick that killer habit, then describes recent smoking cessation methods. On a first read it feels informative and balanced. It mentions that one approach “seems to have its promoters and detractors,” that a particular product “may taste like a dirty ashtray,” and that the newer option “may lead more people to kick the nicotine habit.” Nothing in the paragraph looks obviously wrong, which is precisely what makes it a useful exercise.

The very fact that the topic is contested matters. Tobacco remains a serious public health concern, and bodies such as the World Health Organization track the effectiveness of different quitting methods carefully. When the subject is this important, the difference between a verified statement and a personal impression is not a stylistic nicety. It changes whether a reader can act on what you wrote.

Spotting the opinion sentences 🔗

Apply the verification test to each of the three phrases. “Seems to have its promoters and detractors” uses the qualifier seems and reports a vague split in attitudes with no figures attached, so it cannot be checked. “May taste like a dirty ashtray” is a sensory judgment built on the hedge may; taste is subjective and a dirty ashtray is a comparison, not a measurement. “May lead more people to kick the nicotine habit” predicts a future outcome with the same hedge and offers no study, sample size, or success rate to confirm it. All three express judgment rather than proven fact, which makes all three opinions.

Notice how natural they sound. None of them shouts “this is my personal view.” They are stitched into otherwise neutral prose, and that camouflage is the real lesson. Subjective information can be persuasive precisely because it is dressed as observation, so a careful reader has to slow down and interrogate each sentence individually.

Finding the topic sentence 🔗

Once you have flagged the opinions, look for the sentence that controls the whole paragraph. The topic sentence states the main idea and tells the reader what everything else will be about. In business and technical writing it usually sits at the very beginning, because direct organisation lets a busy reader grasp the point immediately without hunting for it.

In our example, the opening line announcing two new ways to kick the smoking habit is the topic sentence. It sets the boundary of the paragraph: the sentences that follow should describe those two methods and nothing else. A strong topic sentence does this guiding work. It informs the reader of the paragraph’s direction and keeps every later sentence accountable to a single idea. If a sentence does not support that controlling idea, it does not belong in the paragraph.

Recognising the paragraph development method 🔗

Knowing the topic sentence lets you see how the paragraph is built. A well-developed paragraph has four features: a topic sentence, unity, coherence, and adequate support. Writing instructors often teach two memory aids for this. One is the MEAL plan, which stands for Main idea, Evidence, Analysis, and Link. The other is the PIE method, where the writer makes a Point, Illustrates it with detail, and Explains how that detail supports the point.

Our smoking paragraph follows a recognisable pattern: it leads with the main idea (two new methods exist), then develops that idea by describing and comparing the two approaches. This is development by comparison and contrast wrapped around a deductive structure, where the general claim comes first and the specifics follow. Identifying the method is useful because it tells you what the paragraph is trying to achieve, and that helps you judge whether the supporting sentences are doing their job or merely inserting the writer’s preferences.

The rewriting practice: turning opinion into fact 🔗

The final and most practical step is to rewrite the paragraph so it carries information rather than impressions. The goal of objective writing is to support assertions with research instead of relying on personal belief or experience. This means stripping out the hedges and judgments and replacing them with verifiable detail wherever you can.

Take “may taste like a dirty ashtray.” A factual revision would report something measurable, such as the percentage of trial participants who discontinued the product because of its flavour. Take “may lead more people to kick the nicotine habit.” A factual version would cite a quit rate from a named study over a defined period. And “seems to have its promoters and detractors” could become a neutral statement of how many clinicians recommend the method against how many advise caution, again drawn from a real source. The aim throughout is to use language that is clear, objective, and free of unsupported generalisation.

If you cannot find evidence to replace an opinion, the honest move is to drop the claim rather than disguise it as fact. A shorter, fully verifiable paragraph always serves a reader better than a longer one padded with judgments. That single discipline is what separates a credible report from one that quietly invites doubt.

Why this skill carries into every report you write 🔗

This exercise looks small, but it trains a habit you will use constantly. Workplace reports, project proposals, market summaries, and recommendations all depend on the reader being able to separate what is established from what is merely the writer’s view. When you can spot an opinion inside your own draft, you can decide consciously whether to support it with evidence, label it clearly as a recommendation, or remove it. The smoking cessation paragraph is just a training ground; the muscle you build here is the one that makes your professional writing trustworthy.

What do you think? When you reread your own last report, can you point to a single sentence that sounds like a fact but is really your opinion in disguise? And where the evidence simply is not available, would you rather rewrite the claim factually or cut it altogether?
