Bit of a Tangent

016 | Free Will, Compassion, and Reinforcement Learning

September 24, 2019

This is part 2 of our series on free will! In this episode we reconcile how it is that we can feel like we have free will (even when we don’t), give an evolutionary argument for why this might be the case and show how knowing this makes us more compassionate people who are (paradoxically) better at achieving our goals. Along the way, we explain what a Bayesian Network is (and why you should care about yours), and give an introduction to some of the key ideas and concepts in the field of Reinforcement Learning (a subfield of AI) and how we can use these concepts to clarify our view of ourselves and the world!
