# Search engines decide what counts as knowing. The field that studies knowing was never asked.

**What it is**
Epistemology asks what makes a belief knowledge and who may say what is true.

**The problem until now**
Search engines and answer systems took over that role, and the older answers were never applied to them.

**What you can do from here**
You can judge which claims deserve reliance, and see what a page must show before a reader, or a machine, is entitled to rely on it.

*Epistemology: How the parts depend on each other.*

## Try this first

Three tests, about ten minutes. They show when a claim deserves reliance.

Tests on this page you have run: 0 of 3. The count stays in this browser only.

Test: Epistemology

- Ask an assistant a question you would normally put to an expert.
- Note the answer in your own words.
- Think: would you act on the answer without checking it, and why?
When relying on a claim is justified.

Test

- Take one claim from your own site and ask what would make a stranger believe it.
- Put it aside for a moment.
- Think: does the page show that, or only assert it?
What a page must show to be believed.

Test

- Search a contested question in your field and open two results that disagree.
- Put them aside.
- Think: what would settle it, and does either page offer that?
How a disagreement is decided, or left open.

Epistemology asks what has to hold before something counts as known: what evidence is, what justifies a belief, who may assert without proof, and how a person without the expertise decides whom to believe. It has worked on those questions for two and a half thousand years.

## Subjects in this field

[Epistemic authority](https://www.searchresultoptimization.com/epistemology/epistemic-authority/): Who may say what is true, and what happens when a machine takes that role.

[Epistemic trust](https://www.searchresultoptimization.com/epistemology/epistemic-trust/): The readiness to accept what you are told, and what shapes it.

[Evidence](https://www.searchresultoptimization.com/epistemology/evidence/): What counts as proof, and the machinery that decides it.

[Credibility](https://www.searchresultoptimization.com/epistemology/credibility/): How a listener decides a statement counts, and what rhetoric leaves unexamined.

[Coherence](https://www.searchresultoptimization.com/epistemology/coherence/): Whether statements hold together, and whether that is a reason to believe them.

[Verification](https://www.searchresultoptimization.com/epistemology/verification/): Whether a statement can be shown true, and what replaced the attempt.

[Falsification](https://www.searchresultoptimization.com/epistemology/falsification/): Refutation as the engine of knowledge, and the ways it is evaded.

[Hermeneutics](https://www.searchresultoptimization.com/epistemology/hermeneutics/): The theory of interpretation, applied to machines that read before people do.

A search engine answers them every second. It decides which sources count, which claims are shown, and which are not shown at all. An answer system goes further and writes the claim itself, with no warrant offered and none asked for.

The eight subjects below are the parts of that field which bear on search directly. Each one states what is settled, names what the usual treatment leaves out, and answers the questions that follow.
