In statistics, samples are drawn from a population in data-generating process (DGP). Standard errors measure the uncertainty sample estimates of parameters. science, evidence is generated to test hypotheses an evidence-generating (EGP). We claim that EGP variation across researchers adds uncertainty: non-standard errors. To study them, we let 164 teams six on same sample. find sizeable, par wit...

Abstract The MICROSCOPE mission aims to test the weak equivalence principle (WEP) in orbit with an unprecedented precision of 10 −15 on Eötvös parameter thanks electrostatic accelerometers board a drag-free micro-satellite. is determined by statistical errors, due environment and instrument noises, systematic errors which this paper devoted. Systematic error sources can be divided into three ca...
