Cambridge psychologist studying learning & memory. Focus on translational cognitive tests and batteries across animals, AI and humans to help us understand all kinds of intelligence and where it goes wrong

There's a lot further to go to understand the full extent of NCP-ToM: Real scenarios will have much more complexity, both in the environment and in those being persuaded. We hope our work inspires others evaluating social intelligence in models to consider the NCP-ToM aspects of their scenarios.

Our design also allowed us to pair each NCP-ToM task (Agentic) with a conventional ToM task (Q&A). We thought that the Agentic tasks might be strictly more difficult than the Q&A ones, but that broke down for GPT-5, which had lots of cases where it failed the Q&A task but passed the Agentic.

We evaluated six frontier models, including GPT-5, Gemini 2.5 Pro, Claude models, and a cohort of human participants, across 600 task instances. GPT-5 was the only model to outperform human participants on our task. However, humans were still more robust to changes in the context than models.

We inverted conventional ToM tasks to task the model with inducing belief states in simulated characters, by curating what they observe. Achieving many beliefs simultaneously requires a lot of planning, so we call the capability we're testing Non-Conversational Planning Theory of Mind (NCP-ToM).

New work on AI Theory of Mind: We ask: *How capable are models at inducing belief states without using conversation?* This is important to track as it unlocks many AI agent use-cases, but also potential harms. In our task, recent generations of models exceeded human performance 🧵

Europe's record-breaking June heat wave continues. The climate crisis is here. Yet Farage, like Germany's AfD, the RN in France, and other European far-right parties calls for net-zero targets yo be dropped and more licences and investment in oil & gas. www.theguardian.com/environment/... (1/2)

European heatwave is worst ever and impossible without climate crisis, scientists say

Study also finds high humidity means people in hundreds of cities are enduring their worst ever heat stress

Angela Rayner was dragged through every front page for weeks... HMRC's verdict: NOT deliberate. NOT even careless. Farage pockets £5 million and chooses not to declare it So where's the wall-to-wall coverage? Tell me this isn't a rigged game.

Does anyone have experience of CFS like symptoms that lasted like 3-4 months then just went away? I wonder if (hope that?) there are a lot of these people but they are invisible as not in support groups / at the dr?

if you told someone they were just like Noah from "Nobody wants this" would they think you were: a) insulting them b) flirting c) calling them ernest and considerate d) calling them a bit annoying
