I think my favorite journalists are ones who have “strong opinions loosely held”. Like it’s interesting to go in with a hypothesis and maybe even a desired outcome as long as you are willing to take the data as it comes.
The worst is the opposite people with an agenda who extract the one counterpoint to a 500 page research paper and write an article about how the whole papaer validate their assumptions
But somewhere in the middle is the boring boilerplate overview that takes no real stance at all.
