Majestic, well done @rickcarlsson.bsky.social

Psychology has a whole cottage industry in which people come up with some construct that is essentially "attitudes/beliefs/expectations/feelings about X", and then the central claim is that this construct is a super important determinant of future X outcomes.>

I've used Lavaan almost every (work)day for 15 years, but this open source labour of love has never received proper institutional support. I'm delighted to be a small part of an 1.5M OpenScienceNL award, led by Jorgensen, to completely revamp and futureproof Lavaan www.openscience.nl/en/news/45-p...

Project Implicit gives you feedback when you complete an IAT, and the IAT literature has aspired to individual level measurement since its inception.

In this article, we quantify the individual level uncertainty around these estimates and show that IAT effects can say very little about individuals.

When two measures reflect the same latent construct, treating them as independent predictors is a recipe for fake “incremental validity.”

In the implicit-measure debate, this is probably happening: feracotommaso.github.io/posts/iatmea...

🚨 SynthNet is out 🚨
Researchers propose new constructs and measures faster than anyone can track. We (@anniria.bsky.social @ruben.the100.ci) built a search engine to check what already exists and help identify redundancies; indexing 74,000 scales from ~31,500 instruments in APA PsycTests. 🧵1/3
