The evidence establishes
Use when the named source and calculation directly support the descriptive claim for the defined population and period.
Research protocol · Version 1.1
How the Research Desk moves from a public question to a claim that readers can inspect, reproduce, challenge, and correct.
Direct answer
A claim is reliable only to the extent that readers can identify the population, measure, period, source, calculation, uncertainty, limitations, authorship, and correction history behind it.
The method does not treat a citation as proof by itself. It asks whether the cited evidence actually measures the claim being made.
The governing rule
A useful brief does more than cite a study. It identifies the exact population, measure, period, and uncertainty behind every central claim.
When evidence is mixed, incompatible, or incomplete, the conclusion must say so plainly. “We do not know” is a valid result.
Seven-step protocol
Name the population, geography, period, and outcome before searching for evidence.
Prefer primary government data and original peer-reviewed research. Record contrary findings, not only supportive ones.
Check whether race categories, age universes, survey designs, and measures can be compared across sources and years.
Publish numerator, denominator, formula, rounding, uncertainty, and a downloadable table whenever feasible.
Describe the pattern first. Do not turn correlation into causation or a group average into a judgment about individuals.
State missing variables, measurement error, small samples, definition changes, and alternative explanations.
Date every release and document material corrections without silently rewriting the historical record.
Claim language
Use when the named source and calculation directly support the descriptive claim for the defined population and period.
Use when the pattern is credible but the period, sample, compatibility, or causal explanation remains incomplete.
Use when the available source does not measure the question or cannot distinguish competing explanations.
Source hierarchy
Government datasets, survey microdata, administrative records, or original data collected under a documented method.
Peer-reviewed articles, working papers, and technical reports with visible methods and data.
Systematic reviews, government research summaries, and scholarly books that accurately synthesize primary work.
News reports, organizational explainers, and commentary. These may frame a question but should not anchor a statistical claim.
Review status
Research Desk briefs are authored and editorially reviewed by Tyler Burns unless another contributor is named. They are not independently peer reviewed unless a brief later names the reviewers, scope, date, and outcome of that review.
The site’s .org address, academic citations, and links to government agencies do not confer institutional endorsement.
