Hold on. I think it's the author and editor's jobs to evaluate the source's arguments before publishing them. The reason to demand accountability and responsibility from journalists is because we have to place a certain amount of trust in them. Trust but verify, sure, but it's not possible—let alone practical—to evaluate the sources used by every article you read. As it turns out, even journal reviewers don't have time to do that for a handful of quarterly articles, even when they are paid to. So, I don't know how lay readers would be expected to do this for every single article they read on a daily basis.
And I am not interested in saving authors the effort of rewriting parts of an argument, I think I want them to do that if it is necessary for their article.
