Matt Taibbi didn't have a story before he began investigating the financial sector corruption leading up to and following the 2008 crash.
Jeremy Scahill didn't know the details of the Gardez massacre until he got a contact to actually drive him to the scene. (An act so dangerous I believe he called "incredibly stupid" in his documentary "Dirty Wars.")
I have no idea what David Barstow thought he had figured out when he wrote the Pulitzer-winning "Pentagon Pundits" story for NYT. But the evidence he uses in the story clearly backs up the meat of his claims, and a GAO report corroborates it. So why would it even matter in this case?
For Seymour Hersh's Abu Graib abuse story his pre-conceived notions are similarly irrelevant due to the photographic evidence.
Ronan Farrow's preconceived notions about the Harvey Weinstein case are similarly irrelevant.
Hell, consider the leaker to Project Veritas who somehow got the footage of Amy Robach talking about ABC shelving her story on Epstein. What's the relevance of Project Veritas' goal or political bent given that was a genuine video of Robach passionately discussing the shelved story?
> I'll just say if you notice how dumb journos are when they cover subject matter you're a unrelated professional in, being the "who" in receiving end of news coverage lets you see just how much they want to draw conclusions for the rest of the world unless you work on visibility to counter their obvious narrative angles.
But for the most impactful ones it's almost certainly not the same "dumb journo" from your area of expertise writing the story. Given that newspapers hire writers with as varied talents as Barstow and, say, Thomas Friedman, your shortcut seems quite likely to lead to a flurry of "dumb journo" false positives.
