A key aim was to provide a synthesis of the current experimental work that can illuminate metacognitive function and dysfunction in relation to psychiatric and neurological disorders, and contextualise the very fast-moving world of exposing metacognitive mechanisms in AI systems (not just LLMs!)

We now have an increasingly detailed understanding (although with much more still to discover) of how metacognition is supported by a collection of neural and computational building blocks in human and animal brains

I try to articulate the potential of this field to integrate multiple perspectives on how brains and minds work. Measures of metacognition connect to subjective experience via links to introspection, while being grounded in tasks and models that can be applied in humans, animals and AI systems

The PEB was previously thought of as a heuristic bias in human metacognition, but Webb et al. showed it emerged naturally in neural networks operating in richer stimulus spaces, and now Wiktoria showed that it might be a general principle of confidence formation in high-dimensional spaces

Playing around in Matlab with similar SDT spaces I noticed that the confidence surfaces became “detection-like” – more sensitive to whether a stimulus element was present or absent, rather than what it was. It was one of those rare but exciting “that’s interesting…” moments

And finally, we retrain Webb et al.’s neural networks on variable stimulus sets, showing that the expected PEB scales with the dimensionality of the stimulus set 10/N
120
Steve Fleming @smfleming.bsky.social · 25/10/2024
We show that this effect can be observed not only for two-choice decisions, but for N-choice decisions (where dimensionality k > N) 9/N
120
Steve Fleming @smfleming.bsky.social · 25/10/2024
In these higher-dimensional SDT spaces, Bayesian confidence criteria for a two-choice discrimination become detection-like – again, no heuristics and biases 8/N
110
Steve Fleming @smfleming.bsky.social · 25/10/2024
Within SDT, this can be modelled as confidence criteria being detection-like – rather than being parallel to the major diagonal, and sensitive to RELATIVE evidence, they deviate from the diagonal and become sensitive to ABSOLUTE evidence - as in this nice figure from @matanmazor.bsky.social 4/N
