I'm writing a letter criticism to a local newspaper for publishing a letter expressing climate change denial.
I have this line I'm struggling to find a word for:
In the era of fake news and post-truth, the newspaper would do well to exercise some journalistic [something] and make it clear what the truth about the matter is.
Here, what I'm getting at is that the newspaper has both the expertise (in being truth gatherers) and ability to do a thing, though they don't have the obligation to do so.
In other contexts you might say:
The cook should exercise his culinary [something] and insist he be provided with the finest olive oil.
The doctor should exercise his medical [something] and tell his patient that the rash should be treated, even though she came in for a runny nose.
the [adjective describing the area of expertise] [something] format isn't necessary for the word I'm looking for.
