Peer review

Developments in science and medicine are frequently the subject of news headlines and public discussion. With increasing amounts of scientific information being put into the public domain, and a growing number of organisations involved in promoting and discussing scientific research, it can be difficult to judge which research claims should be taken seriously. Which are ‘scares’? Sometimes scientists are reported as saying conflicting things. How do we know what to believe?

The arbiter of scientific quality

There is a system called peer review that is used by scientists to decide which research results should be published in a scientific journal. The peer review process subjects scientific research papers to independent scrutiny by other qualified scientific experts (peers) before they are made public.

More than one million scientific research papers are published in scientific journals worldwide every year. Despite its extensive use and recognition among scientists in assessing the plausibility of research claims, in the rest of society very little is known about the existence of the peer-review process or what it involves.

Sense About Science believes that peer review is an essential arbiter of scientific quality and that information about the status of research results is as important as the findings themselves. We have a very serious commitment to popularising an understanding of how scientific quality is assessed. To this end, we published a short guide to peer review. The guide was one of the key recommendations of our Working Party on peer review, which was established in 2002. We have also developed, together with teachers, an education resource complete with worksheets, articles, and comprehension and role play exercises. It will arm students, and anyone else that uses it, with the tools to question science stories from the media.

In July 2012, members of the VoYS network launched their own guide to peer review for early career researchers Peer review: the nuts and bolts.
