The vast majority of scientists are honest, but recent years have seen many cases of scientific misconduct come to the surface, implying there is a systemic problem. The financial and reputational rewards that come with headline-generating results make research fraud all too tempting. High–profile papers on stem cells, superconductivity, psychological priming, drug efficacy and ocean-heat content have been retracted.
Retraction Watch, an organisation that pushes journals to withdraw dodgy studies, estimates that 5,000 papers are retracted a year but that this is a tiny fraction of how many should be. And they argue that most scientists who retract papers suffer no career setback, while ‘the ones whose papers haven’t been retracted have even fewer worries’.
