There are plenty of examples of this kind of "science" but here's a typical one from National Geographic:
A magazine, one that caters to the scientifically literate, using generally accepted science as given.
National Geographic is known more for their photography and popular general stories about exotic people and places; exotic being different than at home. Original research is not reported because it would bore their audience.
Interestingly, NG does fund scientific research. I was part of a team that applied for and received a research grant from NG. We received funding from several other sources also. The papers reporting the research that were subsequently printed were not published in National Geographic and all that appeared there was a short paragraph in their news section on one aspect of our observations.
Our primary paper was published in the journal
Biogeography and included paleo-biogeography, fossil distribution, modern species geographic distribution and molecular analysis (of all the species of one dragonfly family), and plate tectonics.
So this is another example of a flat assertion of what purports to be fact. Nothing tentative here, no consideration of different possible interpretations. ...
Again, this is generally accepted science for scientifically literate people and the background does not need to be regurgitated, because it is understood.
The documentation of the scientific research that supports the assertions fills libraries at universities around the world. Stories in National Geographic are written to appeal to general readers and are not meant to be speculative but rather based on "generally accepted science" that doesn't need to be explained in every story.
I remember some stories in the 1960's about medieval Europe and the growth of Christianity that really fascinated me when I was in high school. They inspired me to dig deeper into archaeology. That is what normal people do; they follow up to understand accepted science. If you haven't done the research you don't have a sound basis to criticize the scientific conclusions.
