Ideally,
science is defined as systematic, neutral and reproducible. Yet, it is becoming
increasingly more apparent that these features are lacking even in studies
published by high-profile scientific journals. It is not difficult to suggest
reasons that could account for the irreproducibility and bias across scientific
fields: poor peer-reviews, funding pressure and lack of publications of
replication studies. In The Economist,
a journalist reports on why science is not as self-correcting as we think,
pointing our attention to various aspects of the publication process and execution
of science. The article touches on some interesting statistics, which help us
understand why poorly performed, and even falsified studies, make it through
the peer-review process ultimately getting published. Specifically, the
journalist points to the fact that over time, peer reviewers become worse at
identifying errors and holes in the articles they are reviewing. While The Economist calls
it “carelessness”, one has to acknowledge that these peer-reviewers are usually
selected because of their respectable position at a research-intensive
institution. Peer-reviewers lead laboratories that need funding and student
mentoring and they may also have teaching responsibilities. The fact
that peer reviewers are “busy with their own life” does obviously not justify
their insufficient analysis of research studies; however, it does suggest that
selecting “disinterested” scientists as peer-reviewers is not the optimal way
to ensure sound science is published. On Vox.com,
the journalist Julia Belluz interviews the founders of PubPeer, a blog that
facilitates an anonymous discussion of published journals’ scientific methods
and findings. What is inspiring about this blog, is that it enables a neutral
platform for ongoing discussion based on insightful comments and
well-constructed arguments. Moreover, these discussions are not dominated by
high-profile researchers that tend to dominate (and bias) specific scientific
fields. An obvious problem with PubPeer is that it is entirely voluntary and
therefore unreliable in its consistency and standards. However, PubPeer
inspires us to re-consider the traditional peer review process. Perhaps,
instead of “careless and flawed” high-profile peer-reviewers, independent organizations
should be in place to fulfill the practices of peer-reviewing. Specifically,
such an independent and neutral institution can ensure that replication studies
are given the necessary attention, for example, even if journals are not
interested in publishing the findings, they can enhance their public attention
through the media. Although history can suggest that science was conceived
through bias and irreproducility (see Scientific American), it does not mean the present scientific community should not improve
and develop their standards for the research that is being performed and, as
importantly, communicated to the public.
