content_type=opinionOpinion
Explicitly argumentative writing — columns, editorials and position pieces, where the author is arguing a case rather than reporting an event.
Separated out so an agent can either seek it deliberately — when the question is about what people think — or exclude it when the question is about what is true.
Separating opinion from reporting is what makes a corroboration count mean anything. Twelve columns responding to one news story are twelve documents and one underlying source, and an agent that cannot tell the two types apart will read that as consensus.
