16 Reasons Why Most Studies Are Wrong
Even doctors, who are supposed to studiously evaluate the latest research and interpret their conclusions for patients, are ill-equipped to cut through the confusion. We all had to take basic courses in statistics and data analysis, but the complexity of scientific studies often renders them too tough to properly critique by all but the most wonky bio-statisticians.
In fact, in a celebrated 2005 paper, Dr. John P. A. Ioannidis explained: “Why Most Published Research Findings Are False”. Among his assertions are “The greater the financial and other interests and prejudices in a scientific field, the less likely the research findings are to be true,” and “The hotter a scientific field (with more scientific teams involved), the less likely the research findings are to be true.”
