I can see that it was the “most obvious sense” in your view, but it wasn’t in mine (then again, I watch almost no television, and so fortunately I’m spared the brunt of the “media hammer”). I do appreciate your perspective, though; thus, in the future, if I ever refer to “sin” and “religious/priest/clergy” in the same sentence, I’ll be sure to use a disclaimer so that folks don’t leap to the most unsavory conclusion. I was speaking in general terms, and I’ll specify that in the future, should the topic ever arise.
That’s a very melodramatic interpretation of what I wrote.

I tried to point out if that indeed someone is less-than-honest (for whatever reason … doesn’t have to be a huge and sinister conspiracy, just garden-variety self-interest, as Ridgerunner pointed out very adroitly earlier in the thread), and if his data is then used as a foundation or reference in later studies, then those later studies will also be flawed. GIGO, one bad apple spoils the barrel, house built on sand, etc.
I don’t believe that all the references used are always thoroughly re-tested to confirm their accuracy, no.
Here’s an example, with 21 references (from a physics article):
apl.aip.org/resource/1/applab/v102/i21/p213107_s1?bypassSSO=1#tabs_1_113_1274104113_tab2.
It sounds as though you’re postulating that all the data in all 21 of those references was double-checked by the authors of this article … if scientists really did this every time they did a study, I don’t think they would make much progress, as a huge portion of their time would be spent “reinventing the wheel” so to speak. And how far would it go? In addition to these 21 references, what about the sub-references cited in each of them? Would the authors have to go back and re-test or verify all of that data, as well? How many ‘generations’ back would one go? No, I don’t believe this is standard procedure, although if there are scientists posting here who maintain that they really do double-check every single point of data used as a reference, then I’m open to be convinced.
It would certainly be interesting.
