Original research includes any new ideas, interpretations, data analysis, or conclusions that haven't already been published in reliable, independent sources, even if they’re accurate. Wikipedia has a strict policy against original research to maintain verifiability and neutrality across articles.
This means you can’t add your own expert opinion, unpublished insights, internal data, or firsthand knowledge to a Wikipedia page. You also can't combine facts from multiple sources to draw a new conclusion, even if that conclusion seems obvious. Every claim must be backed by a reliable source that makes the same point explicitly.
Wikipedia's role is to summarize what has already been documented elsewhere—not to break news, advance arguments, or publish new scholarship.
