It's not just academic studies, journalists very frequently don't cite their sources for many factual claims. Their editors and them knowing what or whom it is is way too often enough for them.

It rubs me the wrong way. It feels a lot like: "We know better and can tell you what to think. We don't need to show our work."

That said, it has been getting better, especially for the tech savy younger generation with Twitter links (:P), but their editors are probably trying to keep the number of hyperlinks relatively low.
