- Science is facing a "reproducibility crisis" where more than two-thirds of researchers have tried and failed to reproduce another scientist's experiments, research suggests. This is frustrating clinicians and drug developers who want solid foundations of pre-clinical research to build upon.

Nov 1, 2015 · Now, the most comprehensive investigation ever done about the rate and predictors of reproducibility in social and cognitive sciences has found that regardless of the analytic method or criteria used, fewer than half of the original findings were successfully replicated.

Dec 3, 2018 · A study may be replicable in the former sense but not in the second sense: one might be able to replicate the methods, procedures and analysis of a study, but fail to successfully replicate the results of the original study.

Sep 11, 2015 · Of these, more than 65 percent involved cases of misconduct, including fraud. But even when research teams act honorably, their studies may still prove hard to replicate, a new study finds. Yet a second new analysis shows how important it is to try to replicate studies.
Attempted exact replications cannot therefore become the final arbiters of truth any more than the original studies. In essence, then, every replication becomes a “constructive” (Lykken, 1968) or “conceptual” (Crandall and Sherman, 2015) replication that may or may not add to the existing knowledge.
Jan 1, 2024 · More than 90% of studies predicted not to replicate did not replicate, while 66% of studies predicted to replicate actually replicated [11]. The ability of researchers to judge (to some extent) data quality strongly suggests that there are factors in addition to the technical variability that affect reproducibility and that can be addressed to ...
