Abstract

Recent studies have shown that many results published in peer-reviewed scientific journals are not reproducible. This raises the following question: why is it so easy to fool myself into believing that a result is reliable when in fact it is not? Using Brownian motion as a toy model, we show how this can happen if ergodicity is assumed where it is unwarranted. A measured value can appear stable when judged over time, although it is not stable across the ensemble: a different result will be obtained each time the experiment is run.
