With support from TWCF, researchers at @harvard.edu & the Global Development Incubator developed a trivia game that pairs Republicans and Democrats to cooperate as partners. Contestants gained an understanding that people are more than their political beliefs. 👉 https://bit.ly/4gJn2Jv

Can a Trivia Game Help Heal Political Division? Joshua Greene Discusses "Tango" on "Here & Now"…

What happens when strangers with different political views work together instead of debating one another?

Validated against the original MATLAB pipeline across 6 published datasets (Haddara, Maniscalco, Rouault, Shekhar, Locke). Core benchmark profiles replicate at r = 1.000.

metasignal also ships itmc, an experimental information-theoretic metacognition module: meta-I, meta-Ir1, meta-Ir1_acc, meta-Ir2, RMI (Dayan, 2023; Rausch et al., 2025). Included today, not a roadmap item. Cross-validated against R's statConfR to machine precision (r = 1.0000).

Most LLM eval tools ask "did it get the right answer." Cognitive psychology experiments ask "under which manipulated condition, with which controls, measured how." We open-sourced PsychScanner: an experimental harness for LLMs, not a benchmark, a lab. 🧵

psych scanner: a tool for cognitive evaluations for large language models

LLMs have shown impressive performance in some reasoning tasks, but what internal mechanisms do they use to solve these tasks? In a new preprint, we find evidence that abstract reasoning in LLMs depends on an emergent form of symbol processing arxiv.org/abs/2502.20332 (1/N)

Emergent Symbolic Mechanisms Support Abstract Reasoning in Large Language Models

Many recent studies have found evidence for emergent reasoning capabilities in large language models, but debate persists concerning the robustness of these capabilities, and the extent to which they ...

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.

Experimentology cover: title and curves for distributions.

(1/n) Thrilled to share my first paper at Meta FAIR! "EgoBabyVLM: Benchmarking Cross-Modal Learning from Naturalistic Egocentric Video Data" 👶 Human infants learn language from sparse, noisy multimodal input. Today's VLMs can't. We built a benchmark + challenge to close that gap. 🧵
