Sting operations have been proving that it’s alarmingly easy to publish bogus science. Ergo, it’s more important than ever to consider the source. Ars Technica:
None of this is to say that there is a complete crisis in peer review. At the higher-profile journals with reputations to protect, most of the research is likely to be reliable (with interdisciplinary work being a potential exception). But it should certainly raise an added level of caution about some of the work that is published in the more obscure or overly specialized journals that have popped up in recent years.
