Attribute Every Substantive Claim

Crediting is where honest work begins. Your reader can’t trust your answer if they can’t tell which ideas are yours and which came from somewhere else. This chapter sets the one habit everything else rests on: credit every claim that isn’t your own, and credit it the same way every time. We’ll look at what actually needs a source, pick a single style to keep things simple, and walk through crediting a real claim from start to finish.

What Needs a Citation (and What Doesn’t)?

Let’s start with the words, because beginners get tripped up here. Attribution is simply telling the reader where an idea or fact came from. A citation is how you do it: a short pointer in your text plus a fuller entry at the end. The short pointer is the in-text citation (a name and date, or a number, dropped right next to the claim). The fuller entry lives in your reference list, the list of every source you used, gathered at the end so a reader can find the original.

Here’s the rule beginners most often get wrong: it’s not only direct quotes that need crediting. If you take someone else’s idea, finding, or data, you credit it whether you quote it word-for-word, paraphrase it in your own words, or summarize it in one line. Quote, paraphrase, summary, all three need a source. The honest test is: did this come from me, or from somewhere else? If it came from somewhere else, credit it.

So does everything need a citation? No, and over-citing is its own problem. You don’t credit common knowledge: facts a typical reader already accepts and could find in countless places, like “water boils at 100°C” or “Paris is the capital of France.” You credit anything that is a specific finding, a number, a contested point, or someone’s particular phrasing. When you’re unsure, cite. Over-crediting is a small fix; under-crediting is plagiarism.

Pick One Citation Style and Stay Consistent

A citation style is just a set of rules for how the credit looks. You may have heard of a few: APA (name and date, common in social sciences), MLA (name and page, common in the humanities), and Chicago (often numbered notes). They differ in punctuation and order, not in purpose, and you do not need to learn all three.

Pick one and use it everywhere. The only thing that matters for honest work is that every in-text pointer leads to a matching reference entry, and that you don’t switch formats halfway through. Mixing styles looks careless and makes sources harder to trace.

The pairing always works the same way. A short marker sits next to the claim, and a full entry sits in the reference list:

One consistent style, every claim pointed, every pointer matched. That’s the whole skill.

Attribute a Claim Step by Step

Let’s credit a real claim. Imagine you’re writing about wireless headphones and you read a review on a consumer-testing site reporting that one model lasted 30 hours on a charge. You want to use that number.

Watch the move in three steps:

• Spot the borrowed bit. The 30-hour figure isn’t yours, it’s a tested result. So it needs a source.

• Drop the in-text pointer right after the claim: Independent testing found the headphones lasted about 30 hours per charge (SoundCheck, 2025).

• Add the matching reference entry: SoundCheck. (2025). Wireless headphone battery test. SoundCheck Reviews. [link].

The pointer and the entry share the same anchor (SoundCheck, 2025), so a reader sees the claim, sees who’s behind it, and can jump to the full source. That’s an attributed claim, done once, and exactly the pattern you’ll repeat for every borrowed fact in your synthesis.

Your Turn!

Three sentences below each borrow something but credit nothing. For each, decide what needs a source, then rewrite it with an in-text citation. You don’t need real references, invent a plausible source name and year.

1. The new city budget cuts library funding by 12 percent.

2. Studies show standing desks reduce back pain for office workers.

3. This blender crushed ice in under five seconds in a kitchen test.

Trust your own eye on this one, no AI: spotting what needs crediting is exactly the skill we’re building here. Then check your answer against the model solution found at the end of this chapter.

Let’s Recap!

• Credit any idea, finding, or number that isn’t yours, whether you quote, paraphrase, or summarize.

• Common knowledge needs no source; when unsure, cite.

• An in-text citation flags the claim, a reference entry lets readers find the source.

• Pick one style and keep it consistent across the whole piece.

• Every in-text pointer must match one reference entry.

Crediting is half the job. Next you’ll learn to put a source in your own words without accidentally copying it, the trap that catches even careful writers.

Model Solution

1. The budget figure is a specific number, so credit it: The new city budget cuts library funding by 12 percent (City Finance Office, 2025).

2. “Studies show” borrows others’ findings, name a source: Standing desks reduce back pain for some office workers (Lopez, 2024). Bonus: “studies show” is vague, point to one real study.

3. The five-second result is a tested claim: The blender crushed ice in under five seconds in a kitchen test (GearTest, 2025).
