How and why did human’s develop self-awareness of what we know and don’t know? How does it develop in relation to how we evaluate what other people know? What are the risks of cognitive bias tainting our ability to learn and self correct?
In this episode, we have the interesting question of our own self-awareness, or Meta-cognition, to understand. For centuries philosophers have called on us to “know thyself”, but only now with the tools of modern neuroscience have we been able to scientifically quantify the way we consciously track our behaviour, performance, thoughts and knowledge. So today we’ll be getting into why this is important for learning and error correction; we’re going to talk about meta-cognition’s use for “mind reading” I.e. tracking our confidence in others in their own knowledge, both friends and foes, fundamental for the evolution of our collaborative groups; the implications of cognitive bias blind spots in metacognition for updating our collective beliefs over time; also whether metacognition is proportionally correlated to intelligence; and how technology and AI has and will influence the future of our self-awareness, and whether it’s convenient to try programming AI to be metacognitive too, or if that would invite disaster.
For these matters there can be no better guest than University College London Cognitive neuroscience Professor, Stephen Fleming. He’s the author of the 2021 book “Know Thyself, the science of self awareness”, and founder of the Meta Cognition Group at UCL, and the group leader of the Max Plank, UCL Centre for Computational Neuroscience.
