A great deal of workers' compensation disputes turn on expert testimony, generally medical in nature. The legislative shift from the Frye standard to the Daubert standard, therefore, is important to those who litigate workers' compensation disputes.
Daubert is not new to these pages; see To D or not to D? that it appears, is the Question (January 2016); Daubert better Explained (May 2016); Daubert, We Hardly Knew Ye, Or do We? (February 2017); Dissing Daubert? (January 2019); Daubert's New Day (May 2019); Daubert in the Courtroom (August 2019).
The Daubert considerations include "reliable foundation," relevance, judgment, and evidence-based medical evidence. One method to demonstrate reliability is the publication of processes, hypotheses, findings, and conclusions in "peer-reviewed journals," which is seen as an indicator of acceptance. This is because we count on the peers who review, and we suspect that there will be critical contrary articles published if the foundations are not solid or if the results are not reproducible.
Some reports suggest there has been a trend toward easing peer review standards and evaluation. This is a review that involves evaluation, but there is no resulting judgment about "the importance or novelty of the research." This is seen as not impacting the Daubert analysis, according to Science and Technology Law Review (February 2018).
However, more recently, there is a process underway called "sneaked references" that bears careful consideration. The Conversation (July 2024) notes the challenges of being a researcher, the importance of publishing, and the emphasis there on citing "the work of peers to provide context," and more. The citation process, particularly a "positive citation by other researchers," enhances visibility and credibility.
Credibility is important. The impact of articles in legal proceedings is important. Publication is noteworthy, but the fact is that in one recent year, "more than 10,000 scientific articles were retracted." This could easily have included articles used by experts in workers' compensation proceedings to support opinions on topics from diagnosis to appropriate care to residual function or disability.
More subtle than the withdrawal problem is that there are methods to manipulate this citation system to "artificially inflate citation counts." Authors do this by "add(ing) extra references" to the paper, but not in the visible text. These extras are added as metadata hidden in the article. Thus, there is the impression created that these meta-citations are real, and the "citation counts" for those articles "have skyrocketed."
This lends undue credit to the expositions, findings, and conclusions of those authors. Though they appear to be garnering reviews and acceptance, they are merely gathering hits from readers who cannot see their work, let alone review it, comment, or critique.
The fact is that this may be meaningless or irrelevant in a given case. Nonetheless, counsel would be well advised to remain curious about the provenance of journal articles that are cited in support of scientific conclusions. Additional questions regarding currency (not withdrawn) and selection or reliance criteria may be warranted.
In the end, the credibility of an expert's opinions could be questioned. In any credibility dispute, the "what" (opinion) is only half of the necessity. The credible expert can also describe the "how"; as we all learned in grade school, the answer is one thing but showing your work is crucial.
