Most investigations begin with something that catches your attention. It might be a report, a document, a photograph, or simply a detail that doesn’t quite fit with what’s already known.

At that stage, it’s just information. How useful it is depends on what can be established as fact.

At QuillWorkx, we use a simple 0–5 verification scale to keep track of that process. It helps us judge how much confidence a claim deserves at any given point and whether it is worth pursuing further.

0 — Contradicted

At zero, the available evidence points clearly in the other direction, usually because several already confirmed sources contradict the claim.

The information is still noted. Even bad information can become useful later, particularly if it begins circulating again or its origin becomes relevant. Most of the time, though, it stays where it is unless something new appears.

1 — Very Weak

Here, the claim exists, but there is very little reliable evidence to support it.

We usually place it in a holding pattern and wait to see whether more information emerges. Some claims disappear at this stage. Others slowly gather enough support to justify another look.

2 — Weak

A weak claim has some supporting information, but important gaps remain.

This is usually the point where active inquiry becomes worthwhile. We start looking for material that can either strengthen the claim or expose the weaknesses in it.

Sometimes that means finding another source. Sometimes it means checking dates, tracing the origin of a statement, or finding the document everyone else appears to be referring to without having seen.

The purpose is simply to establish whether the claim deserves to move further up the scale.

3 — Plausible

By the time something reaches three, there is reasonable evidence behind it, although parts may still be uncertain or disputed.

This is often where deeper research begins.

The pieces may appear to fit together, but appearances can be misleading. Two events happening at roughly the same time can suggest a relationship where none exists. People, media, and institutions may repeat the same wording because they all relied on the same original source. An apparent pattern can disappear once the timeline is properly reconstructed.

At this stage, we focus less on finding more material and more on seeing whether the existing pieces genuinely connect.

4 — Strongly Supported

At four, the available evidence points strongly in one direction. Most of the important pieces fit, although some part of the claim still can’t be independently confirmed from publicly available information.

This is often where a remote investigation reaches its natural limit.

Moving beyond that point may require access to internal records or somebody with direct knowledge of what happened. Sometimes that access simply isn’t available.

A finding can still be useful at this level. The remaining uncertainty just needs to stay visible.

5 — Independently Verified

A claim reaches five when the evidence is strong enough to treat it as established with very high confidence.

There should be something solid underneath it: a clear record, direct evidence or several genuinely independent sources that arrive at the same conclusion without simply repeating one another.

The distinction between repetition and confirmation is important.

If ten articles all trace back to the same original report, you still have one source. The claim may look more convincing because it is appearing everywhere, but the evidence underneath it hasn’t become any stronger.

The same problem appears when a story contains several separate claims. One part may be well established while another remains uncertain. A document can be genuine while the interpretation attached to it is questionable. An event can be confirmed while its cause is still unclear.

Each part needs to stand on its own evidence.

The scale also makes it easier to change direction when new information appears. A claim that looked plausible yesterday may weaken as better evidence emerges. Something that lay unresolved for weeks can suddenly become much stronger because a missing document surfaces.

Occasionally, a small breadcrumb that looked almost irrelevant at the beginning ends up opening an entirely different line of inquiry.

That’s really all the scale is for. It gives us a consistent way to decide how much confidence the evidence has earned.

A signal kick-starts the process.

The evidence decides where it ends.
