Proteus phenomenon

The Proteus phenomenon is the tendency in science for early replications of a work to contradict the original findings, a consequence of publication bias.^[1] It is akin to the winner's curse.^[2]

The term was coined by John Ioannidis and Thomas A. Trikalinos in 2005 named after the Greek god Proteus who could rapidly change his appearance.^[3] A 2013 paper argued that the phenomenon might be "desirable or even optimal" from a scientific standpoint.^[4]
