Common questions
What text features do analysts compare across disputed documents?+
Common features include word choice, sentence structure, punctuation habits, spelling patterns and other idiolect markers that tend to stay consistent for a given writer across different documents.
Is authorship analysis alone accepted as sufficient proof in court?+
Acceptance varies by jurisdiction and by the specific method used. It is generally treated as supportive evidence alongside other case facts rather than as standalone conclusive proof.
