Sourcing

Every number on this site is labeled by where it came from.

Not a confidence score we made up. A description of how directly each claim traces to a document you can open yourself.

Why not a score

We do not rate our own accuracy. We tell you where each number came from.

A percentage or a letter grade on our own work would be a number we invented, and the first person who wants to dismiss this site would be right to ask how we calculated it. So we do something narrower and checkable instead.

Every figure and claim on this site carries a label describing how directly it traces to its source. That is a fact about provenance, not a judgment about truth. A label tells you what kind of document is behind a number and how many hands it passed through on the way to us, so you can decide for yourself how much weight it carries.

The rule we follow: the further down this list a claim sits, the more carefully we word it, and nothing below the last tier goes on the site at all.

The labels

Five tiers

What does not appear

The things we left out

Anything without a published method. There are industry rules of thumb circulating that would put a campus this size far above the figures Google has stated. Several of them are on sites that look authoritative. None of them show their work, so none of them are here.

Anything we could not open ourselves. If a figure appears in a summary and we cannot reach the document behind it, we either label it as secondary and say so plainly, or we leave it out.

Property value claims. The research on large industrial neighbors is mixed and location-specific, and nobody has studied Archer County. We could find numbers that support us. They would not survive a question from someone who reads carefully, and one collapsed claim would cost us every claim that is solid.

Health effects. We take noise seriously and we say so in engineering terms. We do not make health claims we cannot source.

Corrections

Tell us when we are wrong

If a number here is wrong, we want to know, and we will fix it in public rather than quietly. Send it through the contact form with the document you are looking at. No name or email required. That includes people who support the project, especially people who support the project.

Primary Every source on this site is listed and, where possible, mirrored on the documents page.
