Scientific integrity and the market for lemons

Abstract

Scientific integrity cannot be adequately ensured by appeals to the ethical principles of individual researchers. Research fraud has become a public scandal, exacerbated by our inability accurately to judge its extent. Current reliance on peer review of articles ready for publication as the sole means to control the quality and integrity of the majority of research has been shown to be inadequate, partly because faults in the research process may be concealed and partly because anonymous peer review is itself imperfect. Consequently, the scientific literature is mixed, with the reader unable always to distinguish the good articles from the bad. Scientific research is subject to market forces that will always provide a motivation for a range of misdemeanours. This has led to a ‘market for lemons’. Regulations, and sanctions against miscreants, need to be modelled on those historically found necessary to limit financial fraud. Practical and effective systems of process control and audit have already been devised to ensure the integrity of clinical and pre-clinical research. These should be adapted for use in a much wider range of research activities.
