Systematic Bias in Comparative Evaluations of Machine Learning Versus Logistic Regression for Clinical Prediction Models: A Meta-Research Analysis Using Trauma Mortality as an Empirical Case
Published: September 11, 2026 10:00
CONCLUSION: This study contributes to the meta-science of prediction-model evaluation: it characterises the methodological architecture that produces apparent ML superiority and translates that diagnosis into minimum standards. Current evidence does not…
Science from the bottom up
Published: September 3, 2026 10:00
How a scientific community is organized can affect whether disagreement drives progress or leads to isolation. Students and postdocs are uniquely placed to build communities that bridge theoretical and methodological divides. Drawing on a student-led…
Estimating the Prevalence of Replication Research Is Challenging, Not Least Because Even a Thorough Database Search Can Be Shallow
Published: August 28, 2026 10:00
Replication-duplicating methods to reexamine findings-is the bedrock of science. To survey this foundation for psychological science, Makel et al. (2012) searched 100 psychology journals, finding that all-fields database searches for replicat* returned 2%…
Structure without semantics: no evidence for bonobo compositionality in Berthet et al. (2025)
Published: August 26, 2026 10:00
Understanding the evolutionary origins of combinatorial communication has motivated studies that analyse the semantic capacities of great ape vocal repertoires. A prominent example is the study by Berthet et al. (2025), which used Multiple Correspondence…
Radical reproducibility, real constraints: An autoethnography of open and transparent research from the inside
Published: August 25, 2026 10:00
CONCLUSION: The study demonstrates that "radical reproducibility" is not merely a technical but a cultural and epistemic project that fosters collective learning, skill development and innovation, and requires systemic and institutional support.
Why are the social sciences hard? Two new hypotheses
Published: August 20, 2026 10:00
Debates about whether the social sciences are harder than the natural sciences rarely analyze what discipline-level hardness amounts to. We offer a simple formal framework that models disciplines as sets of prediction tasks with associated difficulty, and…
Development and internal validation of models to predict postoperative troponin and myocardial injury after noncardiac surgery by incorporating hypotension as a predictor: single-centre retrospective cohort study
Published: August 8, 2026 10:00
CONCLUSIONS: A model including postoperative hypotension to predict postoperative troponin concentrations fits our data well, but did not show sufficient accuracy and is not ready for clinical practice. Better-quality data and additional clinical variables…
What is critical metascience and why is it important?
Published: July 17, 2026 10:00
Metascience uses a scientific approach to understand and improve science. Critical metascience takes a step back to question metascience's common assumptions, methods, problems, and solutions. In this article, I aim to raise the profile of critical…
