Current Incentives for Scientists Lead to Underpowered Studies with Erroneous Conclusions
Current Incentives for Scientists Lead to Underpowered Studies with Erroneous Conclusions
Researchers acting to maximise their fitness should spend most of their effort seeking novel results and conduct small studies that have only 10%–40% statistical power. As a result, half of the studies they publish will report erroneous conclusions. Current incentive structures are in conflict with maximising the scientific value of research; we suggest ways that the scientific ecosystem could be improved.
