Opening peer-review: the democracy of science

Scientific journals have been called the ‘minutes of science’
[1]. Born out of the exchange of letters on scientific topics
and results, publication is a way of documenting what was
done and, particularly in the case of open-access journals,
sharing the outcome. Journal publications are considered
authoritative and are generally used to inform the work
of others, be it further research or, in the case of biomedi-
cine, in treatment decisions for patients. This makes some
kind of quality control all the more important.
The ‘gold standard’for this quality control is peer
review. Described as a form of self-regulation by quali-
fied members of a profession, it was first introduced by
Henry Oldenburg, the founding editor of Philosophical
Transactions of the Royal Society, in 1665 as a means of
vetting contributions to the Royal Society of London and
has persisted in various forms ever since [2].
Peer review is the evaluation of a piece of work by two
or more people of similar competence to the authors;
but, assuming the reviewing process excludes all those
involved in the direct research itself, the persons most
qualified to judge the validity of a submitted research
paper are precisely those who are the scientist’s closest
competitors. This means that the review process can
become adversarial, with referees seeming to see it as
their responsibility to insist on time-consuming additions
and revisions [3,4]. Moreover, under traditional, closed
peer-review policies, the identity of the reviewer is
withheld from the author, presenting them with a
greater opportunity to act arbitrarily. It was in an effort
to combat this bias that some journals introduced
double-blind peer-review, whereby the author’sname
was also concealed from the referee. However, research
is a small world and maintaining that blinding often
proved impossible.
So how did peer review, with these intrinsic issues and
biases, become the judicial system of the intellectual world?
Simply put, peer review is to science what democracy was
to Churchill –‘the worst form of government, except all
those other forms that have been tried from time to time.’
It has served science well, with a widely-held view that,
while it may not be perfect, it is nonetheless far better
than anything else we have been able to devise. Indeed,
the fundamental idea of peer-review seems sound; the
issues lie more with the execution. Under closed systems,
such as that currently enforced by the Journal of Negative
Results in BioMedicine, there is a lack of transparency of
the peer-review process and a lack of availability of
evaluative information about published articles to the
public. Therefore, as of February 2014, the Journal of
Negative Results in BioMedicine will adopt an open
peer-review policy.
Articles already published, or those manuscripts currently
submitted, will not be affected by this change. However,
for all manuscripts submitted during or after February
2014, authors will see the reviewers’names and, if the
article is published, the reading public will also see who
reviewed the article and how the authors responded.
This will be available as part of the pre-publication history
of the published article. The peer review process will
therefore be completely open and transparent, with the
peer reviews being part of the record.
Research into the effect of open peer review suggests
numerous benefits, in particular accountability, fairness
and crediting reviewers for their efforts [5-7]. Further-
more, in a recent study, Kowalczuk et al. revealed that
reviewer reports operating under an open peer-review
system were of overall higher quality than those under a
closed system, with higher scores on questions relating
to feedback on the methods (11% higher), constructiveness
of the comments (5% higher), and the amount of evidence
provided to substantiate the comments (9% higher) [8].
Despite this, we recognise that there are also negatives.
Some (junior) reviewers may feel uncomfortable signing a
critical report, especially when recommending rejection
[9]. This reluctance also means that more potential
referees may need to be invited to review a manuscript
openly than under a closed peer-review system (Parkin
EC et al. unpublished observations) [9-11].
Reviewing an article is no easy task and many of us
will have faced the situation where it feels we have put
more thought into our review of the article than the

will give credit where it is due, but moreover will provide
valuable information to those reading the article, sharing
the referees’critique of the manuscript and presenting all
