1/ Very proud of this preprint — and especially because it marks a first step for our lab in a new direction: using what we know about learning not only to diagnose misconceptions, but also to correct them. zenodo.org/records/2303...

You do not know what to read? 📖🤔 Below is a quick digest of this year's papers from the HRL team. The range is a little unusual: from reinforcement learning in rats, to the philosophy of AI, by way of eye-tracking and social-media behaviour. Seven papers, each with a short teaser 👇

Are debates about LLMs driven by evidence—or by our own biases? With @giadapistilli.com, we examine how wishful thinking, cognitive dissonance and explanatory overconfidence fuel both hype and dismissal. Part of a AI & Psychology special issue: more soon! doi.org/10.1016/j.cobeha.2026.101670

#3 of #booksIveRead: Walden Two by BF Skinner. Thanks @stepalminteri.bsky.social for the tip!

The prologue, written in the late 40s, spells out all of the world's problems that have worsened and changed shape, but that have not fundamentally changed: namely those of human behavior, greed, power misuse and our collective inability to create a world for people to thrive.

The novel is fun and easy to read, and promotes a certain type of utopia based on collective living and an education aimed to eliminate feelings of jealousy, property and competition. This would make an interesting read paired with insights from real-world eco-villages, residential meditation halls, and experiments in cooperative living. Certainly worth the read and food for thought.

Hot take: AI should be involved in reviewing We've read this many times Manuscripts under review should not be shared with artificial intelligence, as these tools may not be able to assure confidentiality. AI-generated reviews can contain inaccurate information and biased language I'll push back

I have just finished reading The Technology of Teaching by Skinner it confirmed two ideas for me. First, the image of Skinner as an “evil” behaviorist is false. Reading him directly, I find a profoundly humanist thinker. Second, he may be more useful than expected in our AI-powered era Few takeaways
