Researcher beware - change is coming
The problems with research
It’s always interesting when things come together.
Over the last few days I was at an international meeting where the discussion about the potential value of a Best Practice Guideline document for Researchers was raised because of a general experience that too many research dollars are wasted on non-reproducible and irrelevant studies. An interesting proposal I thought, but perhaps a tad overstated.
Then I get to the airport and pick up the Economist (March 15-21 2014) and turn to the Science and Technology section and there is an article called Metaphysicians which mentions John Ionnidis ( Why Most Published Research Findings are False ). I have discussed this author and this paper before [see: http://www.medicallaboratoryquality.com/2012/12/quality-and-medical-research.html ] because of his interest in doing “research on research”. According to the article, a scourge of modern science is the “waste of effort”. In 2010 “$200 BILLION (85% of total expenditure on medical research) was squandered on studies that were flawed in their design, redundant, never published, or poorly reported”. Assuming those numbers are true, that would certain confirm there is a clear need for help.
According to Ionnidis too many researchers staggeringly over interpret statistical significance in studies that are far too small. Further they have a lack of insight in proper study design and manifest “publication bias” where positive data gets written up for presentation and negative data gets ignored or worse.
Over the years we have observed that graduate students working in research laboratories seeming lack knowledge and interest and respect in running essential common equipment such as autoclaves. Commonly the problem is that they are required to use the equipment, but did not receive appropriate training. In essence they were just pushing buttons. ( I suspect in the minds of their Principle Investigators, autoclaves are mundane compared to DNA analysis.)
Furthermore common procedures of quality control and quality assurance are often incomplete or inadequate and generally not understood.
What they do not seem to understand is that in the absence of basic Quality principles NO research can or should be trusted.
Apparently Ionnidis has doing something about it. He has opened up a Center for meta research with the name Meta-Research Innovation Center at Stanford and the even more appealing acronym METRICS. That will help to define the problems and perhaps develop some answers.
Here are some questions that I would like to see addressed:
A. Would increased training in laboratory Quality result in reduced non-reproducible research and increased value for dollar spent?
B. Could accreditation of research laboratories result in reduced non-reproducible research and increased value for dollar spent?
C. Would introduction of proficiency testing into research laboratories result in reduced non-reproducible research and increased value for dollar spent?
I was intrigued by the notion of a Best Practices in Research Guideline however I also understand that in the current environment such a document would be pursued by those few laboratories that recognize the concepts of standardization and continual improvement. The vast majority would, I suspect, never become aware of its existence, or never purchase it, or never read it, or read it but never consider it as relevant or appropriate to their laboratory.
I know this sounds a tad cynical, but for how long have we taken that approach in the health sciences. “It is not our problem, we are too smart, if it is a guideline then we can ignore it and if it is a regulation we can obscure it.”
This may well be the time when far more aggressive research oversight becomes a reality. If a highly qualified author writes something in Accreditation and Quality Assurance (an excellent journal) its impact is strictly limited. But if articles end up in the Economist, that is a different story. Business folks read the Economist, as do lawyers, and politicians, and University presidents, and many of the general public.
Sooner or later, the right (wrong?) person is going to start putting 2 and 2 together; wasting $200,000,000,000 is an insult to the public purse. And then the regulations start happening, and some people lose their jobs, and some people end up in jail.
Even if we spend $2B on setting up a stringent oversight we are way ahead of the game. And the impact on jobs would be negligible because for every research laboratory that is shut down, some would likely move into consultancy or oversight.
Seems like a win.
