Dr. Steven Novella on the Peer-Review Scandal

"...
Of course, your mileage may vary. Not all peer-reviewed journals are as rigorous. Also, whenever there is any system in place to separate the wheat from the chaff, someone will try to game the system for their own advantage. There also needs to be some monitoring or policing in place to ensure the integrity of the system.
Scientific fraud is a terrible thing. The institution of science requires complete transparency, and fraud violates transparency and reduces confidence in the whole system. Peer-review fraud is not as bad as fabricating data (the ultimate scientific sin) but its bad.
...
I am not trying to point the finger at one culprit, but rather just pointing out that ethical problems in science are not evenly distributed. This provides an opportunity to examine the institutional and cultural factors that may contribute to scientific misconduct. I agree with Patel that we should not overstate the significance of clumping in China or pretend the problem does not exist elsewhere, but neither should we ignore it. Its data.
...
This latest scandal will hopefully provoke another round of self-reflection among scientific journals and improve quality control. Quality control is an endless game, and there will always be problems like this. At least the peer-reviewed literature has the power of retraction, to purge itself of fraud or poor quality when it comes to light."
