Methodology prof in psychology at the University of British Columbia working on Schmeasurement. Into big team science, open science, and latent variables. Flake lab does not study flakes.
Sorry I gave them so much hell on this one but happy to see some solid discussion about the necessity of qualitative approaches. Bravo.
We put forth several recommendations to help tackle this problem, including better curation of measures, careful attention to measurement validation (particularly with qualitative approaches), and adoption of SEM approaches that can probe for method effects.

Our lab has three RRs of simulations underway. It’s a shame to tell my students that our top journal will not consider them for publication. Let’s change that!
Help us show there is support for offering registered reports at one of Psychology's leading method's journal! chng.it/TwwnVBScVb

"Preregistration" lumps three distinct practices into one:
- Study registration
- Protocol
- Analysis plans (SAPs)
To advance open science, it's critical that we distinguish them.

Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.

Hope to see more papers like this that question the performance and trade-offs of more complicated and newer methods with a sample of datasets (not just simulations that can benefit from cherry picking). Combats the publication bias towards new methods and demonstrates on-going comparative work.
