Since its beginnings in the 1940s, automated reasoning by computers has become a tool of ever growing importance in scientific research.So far, the rules underlying automated reasoning have mainly beenformulated by humans, in the form of program …
Reproducibility is a defining feature of science, but the extent to which it characterizes current research is unknown. We conducted replications of 100 experimental and correlational studies published in three psychology journals using high-powered …
This student project involved creating likelihood functions for the Bayesian estimation of cognitive parameters behind choices and response times in R, for the R package EMC2 of the Amsterdam Mathematical Psychology Lab. Particularly, the likelihood …
Beginning in 2011, public scandals and high-visibility critiques of research methods in psychology fed a broader “replication crisis”: foundational experiments could not be replicated, and statistical methods in social psychology demonstrated …
While Open Science has arguably initiated positive changes at some stages of the research process (e.g., increasing transparency through preregistration), problematic behaviors during data collection are still almost impossible to detect and pose a …

This article describes a systematic analysis of the relationship between empirical data and theoretical conclusions for a set of experimental psychology articles published in the journal Science between 2005–2012. When the success rate of a set of …
Failures to replicate published psychological research findings have contributed to a "crisis of confidence." Several reasons for these failures have been proposed, the most notable being questionable research practices and data fraud. We examine …
The crisis of confidence in the social sciences has many corollaries which impact our research practices. One of these is a push towards maximal and mechanical objectivity in quantitative research. This stance is reinforced by major journals and …
