Studies are often wrong because scientists are more interested in funding and careers rather than truth
Twenty years ago last week the statistician Doug Altman published an editorial in the BMJ arguing that much medical research was of poor quality and misleading. In his editorial entitled, “The Scandal of Poor Medical Research,” Altman wrote that much research was “seriously flawed through the use of inappropriate designs, unrepresentative samples, small samples, incorrect methods of analysis, and faulty interpretation.” Twenty years later I fear that things are not better but worse.
Most editorials like most of everything, including people, disappear into obscurity very fast, but Altman’s editorial is one that has lasted. I was the editor of the BMJ when we published the editorial, and I have cited Altman’s editorial many times, including recently. The editorial was published in the dawn of evidence based medicine as an increasing number of people realised how much of medical practice lacked evidence of effectiveness and how much research was poor. Altman’s editorial with its concise argument and blunt, provocative title crystallised the scandal.
