Proteus phenomenon

The Proteus phenomenon is the greater tendency in science for early replications of a work to contradict the original findings, a consequence of publication bias.〔Pfeiffer, Thomas, Lars Bertram, and John Ioannidis. "Quantifying selective reporting and the Proteus phenomenon for multiple datasets with similar bias." PloS one 6.3 (2011): e18362.〕 It is akin to the winner's curse.〔Button, Katherine S., et al. "Power failure: why small sample size undermines the reliability of neuroscience." Nature Reviews Neuroscience 14.5 (2013): 365–376.〕
The term was coined by John P. A. Ioannidis and Thomas A. Trikalinos in 2005 named after the Greek god Proteus who could rapidly change his appearance.〔Ioannidis JP, Trikalinos TA (2005) Early extreme contradictory estimates may appear in published research: The Proteus phenomenon in molecular genetics research and randomized trials. J Clin Epidemiol 58: 543–549.〕 A 2013 paper argued that the phenomenon might be "desirable or even optimal" from a scientific standpoint.
