This was one of the cleanest, most straightforward projects I've ever done, from the hypothesis to the design to the conclusion. Of course still a lot of models, and it was made to look easy just because @jordanlei.bsky.social was so capable!

Happy to have this finally out! TL;DR: The evolution of beliefs over time can be formulated as a dynamical system, and OFC neural activity appears to implement this system with its own dynamics. These emerge without explicit supervision—when animals learn to predict value in simple Pavlovian tasks

I have a question about the future of metrics for hiring and promoting faculty in science. Academic journal articles have been our currency for a long time, but are under extreme & mounting pressure. Is any dept or field already using a better metric *for hiring and promoting faculty*?

This is not just a wake up call for AI in research, it's an inadvertent comment on what needs to change in research culture: "the mass production at faster and faster pace of "true/false" statements could destroy fertile ground instead of breathing life into new ideas"
