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 …

Preregistration requires scientists to describe the planned research activities before their project begins. Preregistration improves transparency in empirical research and is an institutional response to scientific misconduct. This paper studies the …

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 …

Traditional methods of analyzing data from psychological experiments are based on the assumption that there is a single random factor (normally participants) to which generalization is sought. However, many studies involve at least two random factors …

This book provides a non-mathematical introduction to the underlying theory of Efa and reviews the key decisions that must be made in its implementation. Among the issues discussed are the use of confirmatory versus exploratory factor analysis, the …

Preregistration has been proposed as a useful method for making a publicly verifiable distinction between confirmatory hypothesis tests, which involve planned tests of ante hoc hypotheses, and exploratory hypothesis tests, which involve unplanned …

In recent years, the discipline of political science has experienced demands and moves toward greater research transparency. While in quantitative research increased transparency through replication has become a fairly accepted convention, in …

Efforts by governments, firms, and patients to deliver pioneering drugs for critical health needs face a challenge of diminishing efficiency in developing those medicines. While multi-sectoral collaborations involving firms, researchers, patients, …
