Authority is about who is speaking. Primary is about how many people stand between you and what happened — and a trusted expert summarising a study is still a summary.
Two sources on the same study, both trustworthy. One of them is the study.
A review article by a leading group, summarising a landmark study in one paragraph.
The study. The method section, the sample size, the table the paragraph was written from.
One is the record of what happened. One is a respected account of that record, written by somebody who read it for you.
Authority answers who is speaking. Primary answers how many people stand between you and the event. The two are independent — a respected researcher writing a blog post is highly authoritative and two layers deep, and an obscure dataset nobody has heard of is primary.
Every failure here has the same shape. A layer in the middle dropped or bent something, and whoever quoted it never saw the original — so the error travelled onward with a new name on it, and the person who inherited it had no way to know.
Tap a source, then tap whether anything sits between it and the event. Then see how deep each one sits.
Pick a situation. Every one of these came from a source worth trusting.
The review is well written, widely cited, and by people who know the field. One sentence in it bends the study's finding, and the board report quotes that sentence.
Five questions. Nothing is scored.
Five terms, not two. Tap one.
Check if the source is the original record—like the first publication of a dataset or experiment. If the source summarises, explains, or comments on others’ work, it is authoritative. The presence of raw data or direct results is a strong sign of a primary source.
A primary source lets you check the exact facts or data behind a claim. An authoritative source can add context, but if it misreads or simplifies the original, your report could carry those mistakes. For decisions or claims that carry risk, always check the primary.
Yes. Even respected experts or organisations can misinterpret, summarise poorly, or miss key details. Relying on authority alone can pass on errors, especially if nobody checks the original material.
You risk repeating errors, missing updates, or relying on someone else’s interpretation. If the authoritative source misunderstood or oversimplified, your work inherits those mistakes. For high-stakes claims, skipping the primary source can cost credibility or accuracy.
For background, general context, or when a decision does not rest on fine detail, authoritative sources are often enough. For any claim that could be challenged, or where numbers and specifics matter, always check the primary source.
| Type of source | How it is used | Typical example |
|---|---|---|
| Primary | To support direct claims or data | Original experiment paper |
| Authoritative | To provide context or explain trends | Review article or expert report |
If the source spends more time explaining, summarising, or referencing other work than presenting new data or results, it is not primary. Look for phrases like “as shown by,” “according to,” or “in summary”—these signal interpretation.
Every summary is a compression with somebody's judgement inside it. Quote one and you inherit the judgement along with the sentence.
