| Description | Background: Bezdíček, Preiss and Dočkalová (2009) and Preiss and Mačudová (2012) rated the number of publications of Czech academics (professors and associate professors) and evaluated it as insufficient– however, the number of publications says nothing about their quality. One indicator of research quality is its replicability, which is one of the main topics in the present psychology science. It has been shown that at least part of psychological research is not replicable (e.g. Open Science Collaboration, 2015; Klein et al., 2016) and some of the published psychological effects actually do not exist. On the contrary, some effects can remain hidden due to poor research and underpowered design. Objectives: We introduce statistical methods to estimate the replicability of research and apply them to the Czech psychological publications. Sample: The sample was randomly selected from all Czech journal publications indexed on the Web of Science, where it was possible to get a full-text and which tested at least one hypothesis. For each publication, we search their authors and publication impact (number of publications, their citation etc.). Method: In each publication, we identified the main hypotheses and reported statistics. Then we estimated the replicability of these studies using several different statistical tests, both for the whole set and also stratified by the authors and other indicators. Results: The results describe the replicability of the Czech psychological research. We also show the relationship between authors’ publication activity and replicability of their research. |
