While scientists have been conventionally relied upon for
their extensive knowledge and ethical approach to the acquisition of such
knowledge, they now face increasing scrutiny and doubt from both the American
political system and the public. A number of articles touting widespread issues
of irreproducibility and bias have invited even more speculation about the
value of scientific research. So what can be done to bolster a loss of faith in
the scientific process? First, we must address how the current research environment
promotes bias and irreproducibility. Only then can we begin to discuss and
implement changes that will help scientists make more meaningful and valid
discoveries.
Perhaps the greatest challenge that today’s scientists face
is pressure to publish often and in high-impact journals. This pressure is
dangerous because it encourages scientists to over-interpret their findings in
the hope of getting published. We all know that no amount of contemplation and brilliant
study design can accurately and completely encompass the complexity that
underlies the chemical, physical, and behavioral phenomena occurring in the
world around us. At best, positive scientific results should be submitted to
journals as mere support for a proposed mechanism. Unfortunately, the current
hypercompetitive funding climate does not allow scientists to be so humble. Securing
funding is highly influenced by how many papers an investigator has published.
But in order to publish often and in high-impact journals, scientists must
convince reviewers that their work is absolutely groundbreaking, even when it
is not. This relationship between financial security and publication records pressures
scientists to sometimes overreach when it comes to interpreting their work.
Not only does pressure to publish encourage exaggerated
conclusions, but it also facilitates issues of irreproducibility and bias. Scientists
may become less considerate of their own biases and unconsciously less rigorous
in how they evaluate their data, inviting the possibility that one of these
factors has contributed to seemingly publishable findings. This point is expanded
upon in Dan Ariely’s TED Talk “Beware Conflicts of Interest”. Questionable interpretations of scientific
data are then incorporated into manuscripts reviewed by other financially-pressed
scientists who, in an effort to focus on their own work, may not review the
manuscript comprehensively enough to catch its inaccuracies or shortcomings. A
recent Vox article by Julia Belluz points out the failure of the traditional
peer-review process to fulfill this important purpose. Furthermore, she exposes the negative
consequences that can befall well-intentioned scientists who make efforts to
critique faulty scientific papers.
If we are to improve the relationship between the scientific community and the
public, we must first be willing to air the inadequacies of this pervasive “publish
or perish” mentality. Once we acknowledge the shortcomings of this system,
perhaps scientists can perform science and publish findings in ways that do not encourage skepticism from the American public, an audience that scientists must continue to engage.
