I've been learning about open-source intelligence and the difference between finding information and establishing that the information is reliable. Public search engines, archived web pages, domain records, and openly published documents can provide useful context, but each source has limitations. A result may be outdated, incorrectly attributed, or copied from another source that was itself unreliable.
I'm trying to develop a process that records where a claim came from, when it was observed, and whether another independent source supports it. Tools such as the Wayback Machine, public DNS lookup services, and Maltego can assist with specific research tasks, but they don't replace careful interpretation. Privacy and scope also matter, particularly when research concerns real people rather than infrastructure.
For those who practice OSINT professionally, what habits help prevent confirmation bias? How do you distinguish a strong finding from an interesting but unverified lead? I'd like to hear about ethical research exercises and public datasets that teach source validation, timeline building, and reproducible documentation without exposing private information.
