A company offers to replicate research study findings

A company formed in 2011 is offering a new way to validate the findings of research studies:

A year-old Palo Alto, California, company, Science Exchange, announced on Tuesday its “Reproducibility Initiative,” aimed at improving the trustworthiness of published papers. Scientists who want to validate their findings will be able to apply to the initiative, which will choose a lab to redo the study and determine whether the results match.

The project sprang from the growing realization that the scientific literature – from social psychology to basic cancer biology – is riddled with false findings and erroneous conclusions, raising questions about whether such studies can be trusted. Not only are erroneous studies a waste of money, often taxpayers’, but they also can cause companies to misspend time and resources as they try to invent drugs based on false discoveries.

This addresses a larger concern about how many research studies found their results by chance alone:

Typically, scientists must show that results have only a 5 percent chance of having occurred randomly. By that measure, one in 20 studies will make a claim about reality that actually occurred by chance alone, said John Ioannidis of Stanford University, who has long criticized the profusion of false results.

With some 1.5 million scientific studies published each year, by chance alone some 75,000 are probably wrong.

I’m intrigued by the idea of having an independent company assess research results. This could work in conjunction with other methods of verifying research results:

1. The original researchers could run multiple studies. This works better with smaller studies but it could be difficult when the N is larger and more resources are needed.

2. Researchers could also make their data available as they publish their paper. This would allow other researchers to take a look and see if things were done correctly and if the results could be replicated.

3. The larger scientific community should endeavor to replicate studies. This is the way science is supposed to work: if someone finds something new, other researchers should adopt a similar protocol and test it with similar and new populations. Unfortunately, replicating studies is not seen as being very glamorous and it tends not to receive the same kind of press attention.

The primary focus of this article seems to be on medical research. Perhaps this is because it can affect the lives of many and involves big money. But it would be interesting to apply this to more social science studies as well.
