It devolves into scratch my back and I'll scratch yours. I'll peer review your stuff, could you peer review mine?

Also peer reviewed...yes, and what were the results of the peer review? Critical criticism or a big thumbs up? That never seems to go along with peoples claim of credibility due to something being "peer reviewed".

Someone recently made a good point about peer reviews that most of the quality people in many professions are busy doing work so you get a lower tier of people/scientists that take the time to peer review papers. Peer reviewed today likely just means some intern in the industry took a look at a paper.
