Start with a checkable record
Prefer original investigation reports, scientific papers, archived primary documents and official technical accounts. An institution’s account can still have limits. A case’s source list identifies the records behind its evidence exhibits so readers can assess them directly.
Separate observations from explanations
An exhibit should say what was observed or reported. Reasoning prompts compare explanations. The findings synthesize them, while the uncertainty note states what the evidence does not establish. An illustrative diagram is not a measured reconstruction unless explicitly identified as one.
A learning reconstruction has limits
Choices compress complex historical and technical questions into manageable comparisons. They are not a reconstruction of every option available to participants at the time. “Supported” means best supported within that prompt and record; it is not a general guarantee that the source or the case is complete.
Respect the people involved
Disasters and failures can involve real loss. Avoid sensationalism, blame unsupported by the record and the claim that an obvious single error explains a complex event. Discuss systems, incentives, assumptions, decisions and physical mechanisms with care.
AI assistance and responsibility
AI tools assist research, drafting, content structure and software development. Yunus Emre Vurgun is responsible for the project. AI assistance is not independent fact verification or professional peer review. We do not claim that every source has been exhaustively checked or that all interpretations are settled.
Correct the record
If you find an error, use the creator’s contact page with the case URL, the claim and supporting source. Corrections should update the case itself and, for a substantial interpretive change, explain the change to readers. Do not silently convert a disputed claim into a fact.
Editorial independence
Book links are promotions of the creator’s own work. They do not substitute for evidence, and the site does not sell rankings, favorable findings or endorsements. Sources retain their own copyright and licenses. Excerpts must be short, attributed and appropriate to their context.
