We discuss the recent controversy about Integrated Information Theory (IIT), a theory about the neural correlates of consciousness, with Felipe De Brigard, a philosophy and psychology professor at Duke University who signed a letter describing the theory as pseudoscience. The letter: https://osf.io/preprints/psyarxiv/zsr78/ The adversarial collaboration: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0268577 Description of IIT: https://journals.plos.org/ploscompbiol/article?id=10.1371/journal.pcbi.1011465

Psychedelic researcher Robin Carhart-Harris discusses the therapeutic benefits of psychedelics and their impact on the unconscious mind. They explore the debate between neurorealism and the cognitive fallacy, blinding integrity in psychedelic trials, and the relationship between potential information and complexity theory. The podcast also delves into the psychedelic experience, insights gained from psychedelic trips, the potential of video therapy, harm reduction education, and ongoing projects in psychedelic research.

Joe and Rolf discuss new work in neural interfaces that is helping paralyzed individuals communicate. Based on the recent Nature article: Metzger, S. L., Littlejohn, K. T., Silva, A. B., Moses, D. A., Seaton, M. P., Wang, R., ... & Chang, E. F. (2023). A high-performance neuroprosthesis for speech decoding and avatar control. Nature, 1-10.

Rolf and Joe discuss two philosophical theories of the self, Bundle Theory and Ego Theory, based on a paper by Derek Parfit. They return to the topic of the teletransporter, and although Joe is happy to go through the teletransporter, Rolf is convinced it means certain death. Parfit, D. (2016).

In this episode, CogNation goes to the Psychedelic Science conference in Denver to get in on all the excitement. We present four interviews from the conference that represent a range of ideas about the resurgent interest in psychedelics as therapeutics. Bekely Waves The East Institute Balasz Szigeti Manoj Doss

Everyone has a set of beliefs. Increasingly, it seems like we wonder how so many people can hold opposite or contradictory beliefs -- puzzling if we think there's an objective reality. We have a great conversation with Mark Solomon, a clinical psychologist and the host of the Being Reasonable podcast, about Street Epistemology, a conversational method of probing why we believe what we believe. https://www.beingreasonableshow.com/ https://www.youtube.com/@BeingReasonableSpecial Guest: Mark Solomon.

Manesh Girn talks to us about the effects of psychedelics on the brain, based on his recent paper, "A complex systems perspective on psychedelic brain action". We discuss the current state of psychedelics as therapeutics, and how information theory can model changes in brain states that result from taking psychedelics.Special Guest: Manesh Girn.

We talk with Professor Gail Sahar about her new book, entitled "Blame and Political Attitudes: The Psychology of America's Culture War", where she applies social psychology to understand where and why we assign blame in the political sphere. https://www.amazon.com/Blame-Political-Attitudes-Psychology-Americas/dp/303120235X

We talk to Dr. Daniel Sternberg, head of data at Notion Labs, about how to understand new developments in AI (artificial intelligence) like DALL-E-2 and chatgpt. Topics include the possibility for general intelligence in AI, similarities between human cognition and generative AI models, and the potential for sentient AI.

Stephanie Preston (University of Michigan) returns to the show to talk about her latest research. Why do we hoard stuff? And how can we get people to care about the consequences of all that stuff on the environment? Her research has taken her from the strategies that some rats use to hide seeds (some hide in lots of small caches, while others hoard in a single location), to the cognitive/neural/emotional mechanisms of human beings with hoarding disorder. People tend to have emotional attachments to the stuff they own, and although most of us have more stuff than we need, for those with hoarding disorder it can be overwhelming. In other recent research, Stephanie and her colleagues found individual differences in how connected people felt to the environment -- impassive people were less likely to be concerned about the destructive effects on the environment, and that politically conservative people tended to be more impassive.
