New paper in Psychometrika from Yon Soo Suh, myself, & Li Cai. We introduce SISQUOC: a Sequential Importance Sampling algorithm to Quickly and Uniformly Obtain Contingency tables. This algorithm opens the door to fitting propensity analysis of categorical data models. Preproof here: bit.ly/3SYilhO
The conservative conception of masculinity affirms men as breadwinners and promotes toughness. It’s a mentality that fuels the misogynistic online network known as the “manosphere,” a body that may be powerful enough to sway Canada’s political conversation. thewalrus.ca/the-kids-are-lea...
Look, those elitist penguins have been ripping us off for decades.

NIH has rescinded its scientific integrity policy. Hard to see this as anything other than clearing the way for shoddy research on things like vaccines. Regardless of the rationale, it's bad news for public health.

Changes to MSc, PhD and postdoc funding programs from 🇨🇦 tri councils. Harmonization across councils, more awards, and new eligibility for international PhD and postdoc applicants!
🇨🇦New Tri-Agency open access policy: "Agency grantees & chairholders must deposit their article in a Canadian institutional repository at the time of publication [...] preprints deposited under an open license will be accepted as compliant with this policy." science.gc.ca/site/science...
The premise of American foreign policy to Ukraine, today, is one of grievance. It is worth patiently considering the proposals. They reveal little about Ukraine, but much about America in February 2025.

This was a weird paper to write! The sheer number of EFA structures that was deemed 'passing' by CFA fit indices made me realize that perfect simple structure is really more of an assumption than a real tested proposition in CFA.
Thus, good fit of a CFA model only rules out that the true model is an EFA model with severely violated constraints on the ratios of main and cross-loadings, but it does not rule out most other plausible EFA structures.
In fact, fit indices are non-monotone functions of the number of positive cross-loadings in the true model, so that more cross-loadings in the true model does not necessarily translate into worse fit of the CFA model! The relationship becomes monotone only when cross-loadings are of mixed sign.
New paper in Psych Methods with @muhuahuang.bsky.social, in which we show that EFA structures that CFA models will fit well to many underlying EFA-like structures, i.e., models with many cross-loadings. psycnet.apa.org/record/2025-..., osf.io/q2jw8
For newcomers, I and @vincentmourik.bsky.social wrote the 2012 Science article that literally started the Microsoft technical effort to build topological qubits.
The paper is okay, and it includes a lot of negative evidence in the supplement (i made sure of it), 🧵

Yes. PAY even for retracted articles.
This year I have the honour of serving the Psychometric Society as its President, and we have been working hard on the program for the International Meeting of the Psychometric Society (IMPS) psychometricsociety.org/imps-2025 You can submit an abstract here: imps2025.exordo.com
Call for nominations! I know many great people who would do a wonderful job in this position. I also probably don't know many great people who would do a wonderful job as well-- help spread the word! Happy to answer questions about EiC at AMPPS with @psychscience.bsky.social . tinyurl.com/ykpzvp7e
Are psychometric networks sufficiently supported by data such that one can be confident when interpreting its results? We analysed 294 psychometric networks from 126 papers with the Bayesian approach to address this question @jmbh.bsky.social Sara Ruth van Holst @maartenmarsman.bsky.social 🧵

There could be a word missing or it could be a hidden message!
What not to write in reference letters: "Among several undergraduates I've worked with over the years, he is definitely in the top 20."
"We think that it’s too easy for journals and publishers to claim that they have followed COPE guidance, when — in our view — they have only paid lip service to publication integrity while sidestepping the harder work of assessing, flagging and resolving concerns".
