Publication selection bias is a serious challenge to the integrity of all empirical sciences. We derive meta-regression approximations to reduce this bias. Our approach employs Taylor polynomial approximations tothe conditional mean of a truncated …
In his talk, Professor Nosek defines replication as gathering evidence that tests an empirical claim made in an original paper. This intent influences the design and interpretation of a replication study and addresses confusion between conceptual and …
The results of many published studies across many scientific domains are not easily reproduced by independent laboratories. For example, an initiative by Bayer Healthcare to replicate 67 pre-clinical studies led to a reproducibility rate of 20-25% …
We investigated recent meta-research studies on adherence to four reporting guidelines to determine the proportion that provided (1) an explanation for how adherence to guideline items was rated and (2) results from all included individual studies. …
Millions of research papers at risk of disappearing from the Internet: An analysis of DOIs suggests that digital preservation is not keeping up with burgeoning scholarly knowledge.
Statistical rituals largely eliminate statistical thinking in the social sciences. Rituals are indispensable for identification with social groups, but they should be the subject rather than the procedure of science. What I call the “null ritual” …
This mini course was designed to introduce Psychology undergraduate students at the University of Edinburgh (who are working on their dissertation in the academic year 2021-2022) to open research principles and practices.
The course contains 5 …
We outline the need to, and provide a guide on how to, conduct a meta-analysis on one’s own studies within a manuscript. Although conducting a “mini meta” within one’s manuscript has been argued for in the past, this practice is still relatively rare …
The widespread application of mesenchymal stem cells (MSCs) in veterinary regenerative medicine highlights their promising therapeutic potential. However, the lack of standardized characterization and reporting practices across studies poses a …
