Analyst guide · Anomalous Phenomena
Direct answer: A cluster of reports is not automatically a synchronized event. Normalize clocks, apply the predeclared timing rule and examine how the reports were selected before discussing a pattern.
A practical verification workflow
- Convert every reported time to one reference zone while retaining the source offset and uncertainty. Include the inconvenient observation as well as the apparent cluster.
- Apply the rule that existed before looking at the result. Changing a ten-minute window after seeing an outlier creates a different test.
- Trace statements to originating records. Reports quoting one bulletin cannot be counted as independent confirmations of the same phenomenon.
- Document how many windows or comparisons were searched. A selected best-looking cluster needs a defined statistical model before it can support an exact probability claim.
A separate worked illustration
Imagine a compilation that searches hundreds of evenings and displays only the night with the closest-looking reports. One late report is cropped from the graphic. Restoring that report and normalizing its offset may defeat the advertised synchrony without proving that every individual observation was fabricated.
The common reasoning error
Selection concerns are not themselves a numerical p-value. Describe the search process and missing assumptions instead of inventing a precise probability.
Keep an auditable analyst note
Record the question, source identifier, original observation, conversion or calculation, and the narrow conclusion it supports. Separate a confirmed fact from an inference and from information that is still unknown. Keep the original timestamp or unit alongside any normalized value so another reader can reproduce the reasoning.
Practise with the related case
Operation Coincidence Window: Audit the Selected Cluster applies this skill in a fictional evidence packet with five graded objectives. This guide explains the method, not the hidden answer key. Case evidence and entities are invented; the separate illustration above is not a substitute for reading the dossier. Sign-in is required to use the case terminal.
Questions readers ask
Does failing a synchrony test prove every report false?
No. It rejects that particular timing claim, not necessarily each underlying observation.
Can the chance probability be known without a null model?
No. The comparison procedure and assumptions need to be specified.
