The NYT has a useful overview of recent discredited scientific research and a look at the realities of the peer review process.
Because findings published in peer-reviewed journals affect patient care, public policy and the authors' academic promotions, journal editors contend that new scientific information should be published in a peer-reviewed journal before it is presented to doctors and the public.
That message, however, has created a widespread misimpression that passing peer review is the scientific equivalent of the Good Housekeeping seal of approval.
Virtually every major scientific and medical journal has been humbled recently by publishing findings that are later discredited. The flurry of episodes has led many people to ask why authors, editors and independent expert reviewers all failed to detect the problems before publication.
Worth a read.
