Free will: Do we really have it? And what is it, exactly?  In this episode, co-host David Pietraszewski takes the role of guest and explains his recent evolutionary, adaptationist approach to the problem of free will, explaining what people are talking about when they talk about free will, why different people have different opinions about whether it really exists in light of science, and what an evolutionary approach has to say about how to study it in the first place. If you love or hate the study of free will--or think it is a forever-unsolvable mystery-- then this episode is for you!   More about David Pietraszewski: https://cal.psych.ucsb.edu/david-pietraszewski https://scholar.google.com/citations?user=rGFYm8AAAAAJ&hl=en&oi=ao
