We particularly recommend Skeptico’s discussion of provenance and how it enables readers to distinguish woo from genuine research.
Provenance is also useful in determining the validity of scientific claims. If the claim is based on earlier sound science – backed by quality evidence – it is more likely to be true. Not certain to be true, of course. But it will at least have scientific plausibility. But if the claim is based on something that was just made up, then it seems much less likely it would be true.
