Seven Checks for a Reliable OSINT Investigation
Open-source information becomes useful evidence when its origin, limits and interpretation are documented.
Define the question
Write down the decision, relevant entities, time interval and authorized sources before collecting information. A narrow question reduces unnecessary personal-data collection and helps prevent a search from turning into an unrelated profile of a person.
Verify identity and time
Names, profile photographs and usernames can be shared or copied. Use several independent identifiers before joining records. Keep publication time, observation time and event time separate. A repost is not independent confirmation of the original claim.
Preserve context
Record the URL, retrieval time and source type. Preserve context around a screenshot rather than capturing only the desired sentence. Maintain original files separately from annotations; a hash can help detect subsequent file changes but does not prove that the source was truthful.
State analytical limits
Look for evidence that challenges the working hypothesis. Distinguish direct observation from inference, identify unresolved contradictions, and explain confidence in plain language. Public availability does not automatically establish permission for every use. Restrict access and retention to what the assignment requires.
