A report from a Working Party on Equipping the Public with an Understanding of Peer Review, established by Sense about Science in 2002. The Working Party were asked to consider how an understanding of peer review might help the public to evaluate the merit of scientific research. The discussion paper is divided into three sections. The first section covers the peer review process in the public domain, the second provides a description of the peer review process and addresses some of the questions about how and why it is used whilst the third addresses the different ways in which scientific information enters the public domain and how these interact with the peer review process. The report, which has been compiled and presented by Tracey Brown, director of Sense about Science, also contains a guide to peer review. The report is available in PDF format requiring Adobe Acrobat.
