Topic pathway

Evidence, sources and information verification

Preserve digital traces, assess media and AI answers, build timelines and record uncertainty.

What precise fact does the available material establish?

First action

Retain the original, URL, collection time and context. Separate observation, publication time and claimed event time.

Useful output

A source log, unchanged originals, a dated timeline and a summary separating findings, hypotheses and unknowns.

Interpretation limit

A screenshot, detector result or hash answers a limited question. For litigation, ask the relevant professional which recording and transfer process is needed.

Keep the decision traceable

Record the fact being checked, the material reviewed, what remains unknown, the person responsible and the next review trigger. A result is useful when another reader can understand why an action was chosen and what would change it.

When to pause and escalate

Preservation does not mean publication. Keep an intact copy and prepare a limited sharing version. A hash describes integrity of a particular file; it does not establish authorship or truth.

FAQ

Are two screenshots two sources?

Not if they reproduce the same origin. Map publication dependencies before claiming corroboration.

How should a negative search be recorded?

Record query, portal, date, filters and access limits. Conclude only that no relevant result was found within that scope.
