| Samenvatting | The probability of “replication,” prep, has been proposed as a means of identifying replicable and reliable effects in the psychological sciences. We conduct a basic test of prep that reveals that it misestimates the true probability of replication, especially for small effects. We show how these general problems with prep play out in practice, when it is applied to predict the replicability of observed effects over a series of experiments. Our results show that, over any plausible series of experiments, the true probabilities of replication will be very different from those predicted by prep. We discuss some basic problems in the formulation of prep that are responsible for its poor performance, and conclude that prep is not a useful statistic for psychological science. |
