Hard to see how this apparent stereotyping (a) wouldn't apply to people working in nearly every industry and (b) is relevant to this tool.
Definitely, we'd have to look at the studies in this space, namely whether journalists cite their facts, or write their pieces using citable studies/facts, etc. So I also won't accept the OP's statement of it as fact.
Though, in my, supposedly biased, opinion I'd say journalists are quite adept at twisting facts to suit their points, and also of omitting (i.e. cherry picking) facts that support their views/points.
"Journalism" is a broad tent. I suspect there's plenty of room for tools like this one.
