1/ An emerging body of literature suggests that 'simple' organisms (like plants, protists & bacteria) regulate their activity flexibly & intelligently. An increasing number of scientists & philosophers take such behaviour as evidence of cognition. We think this a tad hasty.pic.twitter.com/2PqwGuw1NZ

2/ Our new paper asks what we can learn (& claim) about the biological basis of cognition from the perspective of the free energy principle. We believe the FEP gives us useful theoretical tools to understand how biological regulation differs across multiple spatiotemporal scales.

3/ Extending our previous work on homeostasis, allostasis & interoception (see https://psyarxiv.com/zbqnx/ ), we examine how various kinds of adaptive plasticity can be explained under the FEP. We then consider how these adaptive processes might relate to environmental complexity.

4/ Using a hypothetical model organism based on E. coli bacteria, we develop a three-tiered scheme that maps increasingly sophisticated forms of adaptive regulation & uncertainty reduction onto increasingly complex ('hierarchically deep') forms of active inference.pic.twitter.com/IDTftf3GcP

5/ This analysis enables us to differentiate complex allostatic systems from agents capable of engaging in fully-detached, *counterfactual* active inference. We believe this distinction points towards a principled basis for differentiating cognitive from non-cognitive systemspic.twitter.com/q1AJaGBsDG

And that, in a nutshell, is it ! This paper took an awful long time to write, and taught me an awful lot along the way. Very grateful to all who provided feedback at various points along the journey. Eager to hear what you make of it !
