Course Description: Publication bias is a problem for the credibility of research in general, and in particular when using meta-analyses, as it yields overestimated effects and a possible non-existence of effects. Publication bias is acknowledged among researchers, but the strength of its influence is less well-known. An examination of statistical findings using a large-scale data set was included in the study. Various conclusions were formed across subsets (homogenous and heterogenous). Overall, publication bias, in its most extreme case, suggested weak support in both psychology and medicine.
