There is an ongoing debate regarding preregistration of epidemiologic study protocols. We examine the basic idea that preregistration of study protocols and their associated hypotheses would enhance the reliability of observational research. We …

Trust in science increases when scientists and the outlets certifying their work honor science’s norms. Scientists often fail to signal to other scientists and, perhaps more importantly, the public that these norms are being upheld. They could do so …

Visual comics about significance testing

Null-hypothesis significance tests (NHST), properly used, tell us whether we have sufficient evidence to be confident of the sign of the population effect–but only if we abandon two-valued logic in favor of Kaiser's (1960) three-alternative …

Collaboration between researchers has become increasingly common, enabling a level of discovery and innovation that is difficult if not impossible to achieve by a single person. But how can one establish and maintain an environment that fosters …

Slides for a talk given at SIPS 2016

SMAAT (Sensor-based Mobile Application for Assessment and Tracking) lets you design studies, schedule experience sampling, and collect encrypted survey and sensor data from iOS and Android participants — with real-time compliance dashboards, …

This article introduces a new approach for evaluating replication results. It combines effect-size estimation with hypothesis testing, assessing the extent to which the replication results are consistent with an effect size big enough to have been …

This checklist is intended to help scientists, reviewers, and editors prepare and assess manuscripts for inclusion of critical details relevant to work with pluripotent stem cells (PSCs) and tissue stem cells (TSCs) with the goal of increasing the …

We report evidence of an undocumented method to manipulate citation counts involving 'sneaked' references. Sneaked references are registered as metadata for scientific articles in which they do not appear. This manipulation exploits trusted …
