Methodology

How we score a case

Tabloids hype every case equally; skeptic blogs dismiss every case equally. We'd rather grade them — on the same four axes, with the same yardstick, whether the case flatters our priors or not. The Signal Strength badge on each case is the result.

This is a judgment tool, not a physics constant. Reasonable people will argue a notch either way — and we'd rather you argue with a number than with a vibe. Every score is defended by the article's own sourcing.

The four dimensions

Witnesses

Who saw it, how many, and how reliable are they?

Strong
Multiple independent witnesses, ideally trained observers (pilots, military, police) with no shared incentive to coordinate.
Moderate
Several witnesses, or a small number of high-credibility ones.
Weak
One or two witnesses, or accounts dependent on hypnosis / recovered memory.
None
No direct human witnesses on record.

Instrumentation

Is there hard sensor data — not just testimony?

Strong
Clear radar, infrared, or photographic capture, ideally multi-sensor.
Moderate
Some instrument data or physical traces collected (radiation, soil, injuries).
Weak
Disputed photos, behavioral evidence (e.g. polygraphs), or weak traces.
None
Testimony only; no sensors or physical evidence.

Official record

Did a government or institution document or acknowledge it?

Strong
Formal government files, an official investigation, or an on-record acknowledgment.
Moderate
Logged by an agency or formal body without a firm conclusion.
Weak
Mentioned in records, or acknowledged only informally / years later.
None
No official documentation.

Debunk-resistance

How well does it survive the best prosaic explanation?

Strong
Leading mundane explanations have been tested and fail to account for the core facts.
Moderate
A prosaic explanation exists and fits part of the case, but leaves a real residue.
Weak
A strong prosaic explanation covers most of it.
None
A prosaic or fabricated explanation is well-established.

From points to a tier

Each dimension scores 0 (None) to 3 (Strong), for a total out of 12. The total maps to one headline tier:

Well-Documented
10–12
Strong on most axes. Hard to dismiss without ignoring evidence.
Credible
7–9
Genuine evidentiary weight, with open questions.
Contested
4–6
Real but disputed — depends heavily on which evidence you trust.
Thin
0–3
Little hard support, or a strong prosaic / fabrication case.
