Researchers should be aware of how sex-difference science is (mis)applied in legal and policy contexts.

This article outlines what we call the “narrative of psychology exceptionalism” in commentaries on the replication crisis: many thoughtful commentaries link the current crisis to the specificity of psychology’s history, methods, and subject matter, but explorations of the similarities between psychology and other fields are comparatively thin. Hist...

To those involved in discussions about rigor, reproducibility, and replication in science, conversation about the "reproducibility crisis" appear ill-structured. Seemingly very different issues concerning the purity of reagents, accessibility of computational code, or misaligned incentives in academic research writ large are all collected up under...
Preprint
Addressing issues with the reproducibility of results is critical for scientific progress, but conflicting ideas about the sources of and solutions to irreproducibility are a barrier to change. Prior work has attempted to address this problem by creating analytical definitions of reproducibility. We take a novel empirical, mixed methods approach to...

... The adjacent field of psychology serves as a reservoir of a decade's worth of scientific discussion and proposed methodological improvements (e.g., pre-registration prior to the start of the study, J o u r n a l P r e -p r o o f transparent data processing practices, and reporting effects sizes) [149] that should serve as example in future studies. It has been suggested that the social-structural factors that contribute to the replication crisis are not limited to psychology [150] and may apply to other fields [151]. ...
... HARKing.-A "reproducibility crisis" in science (O'Boyle et al. 2017;Fraser et al. 2018;Hutson 2018;Parker et al. 2019;Bissonette 2021;Nelson et al. 2021;O'Dea et al. 2021) has reinforced the need for caution surrounding practices such as multiple comparisons and hypothesizing after the results are known (HARKing). When the popular R package bipartite is used with its default settings to study plant-herbivore interactions, the networklevel function calculates 47 bipartite network metrics and the grouplevel function calculates 30 metrics: 15 for each host plant taxon and 15 for each herbivore taxon (Dormann et al. 2008)-77 metrics despite few studies addressing 77 distinct questions. ...
... Lowering the bar on the number of (control) experiments conducted or data sets included can have multiple implications for the quality of the science conducted. For several decades now, multiple scholars have claimed science to be in a 'reproducibility crisis' (Guttinger 2020;Nelson et al. 2020). While an abundance of potential causes of this has been proposed (e.g. ...
