Dave and Tamler celebrate their 75th episode by welcoming six BFFs of the podcast and asking them to share the biggest thing they've changed their minds about in their professional careers. You'll hear Dan Ariely on our moral duty to take science into the real world, Laurie Santos on the the role of neuroscience in explaining psychological findings, Yoel Inbar on what it means to do good science as a psychologist, Eric Schwitzgebel on his metaphysical epiphany about materialism, Nina Strohminger on breaking-up with priming research, and Sam Harris on Artificial Intelligence and its perils, and his recently changed views about vegetarianism. (Sadly, we had a technical glitch with the audio when we recorded our most-frequent guest Paul Bloom, but we'll bring him on again soon.) Plus we play some hilarious mash-ups, raps, and voicemails sent in from listeners.Links to info about our GuestsDan ArielyLaurie SantosYoel InbarNina StrohmingerEric SchwitzgebelSam Harris Listener-Created Music in this Episode Special Guests: Dan Ariely, Eric Schwitzgebel, Laurie Santos, Nina Strohminger, Sam Harris, and Yoel Inbar.
