Most people would agree an imperfect attempt with lots of transparency is better than no attempt at all.
The first thing you learn in journalism is that you can't be 100% objective, even if you're 100% truthful.
Let's say you're reporting on Obama's birth certificate, and you write 20 pages of a deep dive into where he was born and all the evidence for it. You are complete and thorough, and you end up concluding that he couldn't have been born in Kenya.
Just the fact that you wrote that much to debunk a nonsensical, evidence-free lie is actually going to make it seem like they had evidence!
You can also neglect to report on things. You can report on 150 burglaries a day and give people the impression that burglaries are skyrocketing when they aren't.
So of course there will be subjectivity that leaks out, but that's not something we should fear to the point of giving up.
