Dr. Fiona Godlee, editor of the BMJ [British Medical Journal], specializes in the unexpected. [A marionette puppet on her desk is] dressed as a doctor, complete with a stethoscope around its neck. Its strings represent the hidden hand of the pharmaceutical industry. Godlee keeps it ... to remind her of the dark forces at work in science and medicine. And she is blunt about the results: I think we have to call it what it is. It is the corruption of the scientific process." Hundreds of papers are being pulled from the scientific record, for falsified data, for plagiarism, and for a variety of other reasons that are often never explained. Sometimes it's an honest mistake. But it's estimated that 70 per cent of the retractions are based on some form of scientific misconduct. As the editor of one of the oldest and most influential medical journals, Godlee is leading several campaigns to change the way science is reported, including opening up data for other scientists to review, and digging up data from old and abandoned trials for a second look. She has strong words about the overuse of drugs, and the influence of industry on the types of questions that scientists ask, and the conclusions that are drawn from the evidence. "I do have a belief in the fundamentality of science to correct itself. We can't do that under the blanket of secrecy," she says. It matters, Godlee says, because bad science can be dangerous. "We do know that patients are harmed, and we know that the health systems are harmed as a result of poor science."
