The big picture for understanding human intelligence research...it is more complex than simply running factor analysis models. Model adapted from one of the giants in the field...Earl Buzz Hunt. #iq #intelligence

🚨 New publication: How to improve conceptual clarity in psychological science? Thrilled to see this article with Rui Mata out. We discuss how LLMs can be leveraged to map, clarify, and generate psychological measures and constructs. Open access article:

Psychology has long struggled with conceptual redundancy, particularly in the form of “jingle-jangle fallacies,” in which different constructs share the same la...

The paper proposes a concrete test for AGI by checking if an AI matches a well educated adult across 10 abilities. And reading it, the obvious conclusion is we are just so far away from AGI level intelligence. They report an “AGI Score” and show GPT-4 at 27% and GPT-5 at 58%,

There are many barriers to AGI but they each seem tractable. It seems like AGI won't arrive in a year, but it could easily this decade. Website: https://t.co/O5S8NyaHQ7 Paper:

For example, testing shows that models get 0% on Long-Term Memory Storage (continual learning). Without persistent memory, current AIs have “amnesia.” Relying on massive context windows is a “capability contortion”—a workaround that masks this fundamental limitation.

Our definition of AGI is an AI that can match or exceed the cognitive versatility and proficiency of a well-educated adult. To measure this, we assess the multiple dimensions of intelligence derived from the most empirically validated model of human intelligence (CHC theory).

The term “AGI” is currently a vague, moving goalpost. To ground the discussion, we propose a comprehensive, testable definition of AGI. Using it, we can quantify progress: GPT-4 (2023) was 27% of the way to AGI. GPT-5 (2025) is 58%. Here’s how we define and measure it: 🧵
