Peer review has become the gold standard to back-up any claim in popular "science" (the scientific community understand that peer review is often just the first stage in proving the validity of your work). Peer review is a powerful first filter for scientific research, but the term has become a marketing ploy for so-called predatory journals.

These are journals which will publish almost anything for a fee. They have become the backbone of the woo-and-con industry, who use them to backup their claims with the golden tag "peer reviewed". It's hard to spot a predatory journal if you are not an active researcher, and only slightly easier if you are. Help is at hand in the form of Beall's List. The journals that make the list are pay-to-publish, and not suitably peer reviewed with any rigour, a number fo them are not peer reviewed at all, as evidenced by the fact that they have published and re-published Get Me Off Your Fucking Mailing List- a paper by David Mazieres which is comprised entirely of the words "get me off your fucking mailing list".
