Evidence Integration and Attribution
Evidence Integration and Attribution
Every strong argument runs on borrowed material. A writer rarely proves a claim using only their own authority. They reach outside themselves for a fact, a quote, a report, a story someone else told them, and they build that material into their own reasoning. The skill of doing this well has a name: evidence integration. The related skill of telling your reader exactly where each piece of evidence came from is attribution. Together they turn a string of assertions into an argument a reader can check.
Insertion drops a quote or a statistic in and moves on. Integration explains what the evidence means and connects it back to the writer's own point, so the reader understands not just what the source says but why it matters here, in this specific argument. A writer usually opens that door with a signal phrase, a short lead-in like "according to" or "the report found," that tells the reader a new voice is about to speak. Attribution comes next: naming the source specifically enough that a reader could go find it and judge its weight themselves. A vague nod to "experts" or "studies" asks for trust it hasn't earned. A named source, a dated report, a specific speaker, gives the reader something real to check.
Doug Cuthand, Cree, a member of the Little Pine First Nation in Saskatchewan and longtime Indigenous affairs columnist for the Saskatoon StarPhoenix and Regina Leader-Post, builds an argument this way in his 2025 column on the Cumberland delta. He argues that the delta, North America's largest inland delta, is shrinking because of hydro dams, irrigation, and climate change, and that this amounts to a treaty infringement against Cumberland House First Nation. He backs that claim with a lawsuit the First Nation filed against the provincial government, a historical record reaching back to the 1774 founding of Cumberland House and the 1875 signing of Treaty 5, and direct testimony, writing that "according to members of the Cumberland House First Nation," the delta is in danger of getting smaller. Each source is named specifically enough that a reader could track it down, and each one does different work: the lawsuit shows the legal stakes, the history shows what has been lost, the testimony shows who is affected and how they know it.
Cuthand does not pile up evidence for its own sake. Every source he brings in serves one claim: a shrinking delta is a treaty issue, not only an environmental one. That is the real test of integration. Not how much evidence a piece contains, but whether every source earns its place by strengthening one clear argument.
As you read Cuthand's column in the next section, watch for the moments where a new source enters his argument. What signal phrase brings it in, and what specific job does that piece of evidence do that the others don't already do?
Integrating evidence means explaining and connecting a source to your argument, not dropping it in and moving on.
Attribution lets a reader judge a source's credibility instead of asking for blind trust.
A signal phrase announces that a new voice, not the writer's own, is about to speak.
The strongest arguments use each piece of evidence to do a distinct job instead of repeating the same kind of proof.
More evidence is not automatically a stronger argument. Evidence strengthens an argument only when it is specific, attributed, and tied clearly to the claim.
Evidence integration: introducing a source, explaining what it says, and connecting it back to the writer's own point, rather than inserting it and moving on.
Attribution: naming a source specifically enough that a reader could locate it and judge its credibility for themselves.
Signal phrase: a short lead-in, such as "according to" or "the report found," that introduces a source before it speaks.
Paraphrase: restating a source's idea in the writer's own words while still attributing it to that source.
Source strength: how much weight a piece of evidence can reasonably carry, based on how specific, credible, and relevant it is to the exact claim being made.
Lesson 12 asked you to judge whether a source was credible and reliable. Lesson 13 asked you to notice how a speaker earns trust, reasons, and moves an audience. This lesson asks you to do what Cuthand does: find your own evidence, from more than one place, and build it into an argument that is honestly and specifically your own.
