Tomorrow, from 9 to 10:15 am at Psychometric Society, join us for our symposium - Generative Psychometrics: Advancing Psychological Scale Development Through Large Language Models. Lara Russell-Lasalandra will (Lara Russell-Lasalandra) talk about AI-GENIE: A simulation study on the fully automatic

At the International Meeting of the Psychometric Society (Psychometric Society ) with Alex Christensen, Aleksandar Tomasevic (Aleksandar Tomasevic ), and Lara Russell-Lasalandra (Lara Russell-Lasalandra)!

Scenes from the International Meeting of the Psychometric Society, 2025!

Yeah we did exactly that

Come learn with me and Lara Russell-Lasalandra how to automatically generate items and validate them (structural validity) using Large Language Models and Network Methods from Exploratory Graph Analysis!

Are you a scientist who uses notebooks for learning, planning, organizing, etc? I am interested in collecting scans of scientists' lab notebooks, field journals, or personal notebooks. Please share some via this form. RT=🤟 docs.google.com/forms/d/e/1FAI…

More and more papers are proposing to use LLMs to simulate human agents in agent-based models. I have strong reservations about attribution/causation/interpretability in this methodology, as I discuss in this article about one (excellent) such paper: 🧪 science.org/content/articl…

💔 How do people break up? 🧵 We found that insecure attachment styles & dark traits (esp. secondary psychopathy) predict more toxic breakup strategies—ghosting, manipulation, escalation—while secure people lean toward healthier endings: authors.elsevier.com/c/1ldqFheKe07mm

The next three days we will enjoy interesting talks on networks and graphs at Institute of Physics Belgrade. We thank to our sponsor PLOS Complex Systems

First talk of netgraph in beautiful Belgrade . Try to guess?

How does OpenAI's OSS-120b, OSS-20b, and DeepSeek models compare to GPT-3.5, GPT-4o, Llama-3, Gemma-2, and Mixtral's models for automatic item generation and validation? How does the in-silica structural validity of items developed with GPT-3.5, GPT-4o, Llama-3, Gemma-2, and

Rethinking Personality: What if the Big Five isn't the full story? Our latest research using Topological Graph Analysis (TGA) has uncovered something remarkable, entirely new personality dimensions that challenge how we understand human traits. While traditional models give us
