TED | 3 Worldview-Shaping Cognitive Biases

What shapes our perceptions (and misperceptions) about science? In an eye-opening talk, meteorologist J. Marshall Shepherd explains how confirmation bias, the Dunning-Kruger effect and cognitive dissonance impact what we think we know — and shares ideas for how we can replace them with something much more powerful: knowledge.

The “Easy Problems” of consciousness have to do with how the brain takes in information, thinks about it, and turns it into action. The “Hard Problem,” on the other hand, is the task of explaining our individual, subjective, first-person experiences of the world. What is it like to be me, rather than someone else? Everyone agrees that the Easy Problems are hard; some people think the Hard Problem is almost impossible, while others think it’s pretty easy.

Today’s guest, David Chalmers, is arguably the leading philosopher of consciousness working today, and the one who coined the phrase “the Hard Problem,” as well as proposing the philosophical zombie thought experiment. Recently he has been taking seriously the notion of panpsychism.

We talk about these knotty issues (about which we deeply disagree), but also spend some time on the possibility that we live in a computer simulation. Would simulated lives be “real”? (There we agree — yes they would.)

David Chalmers got his Ph.D. from Indiana University working under Douglas Hoftstadter.

He is currently University Professor of Philosophy and Neural Science at New York University and co-director of the Center for Mind, Brain, and Consciousness.

He is a fellow of the Australian Academy of Humanities, the Academy of Social Sciences in Australia, and the American Academy of Arts and Sciences.

Among his books are The Conscious Mind: In Search of a Fundamental Theory, The Character of Consciousness, and Constructing the World.

He and David Bourget founded the PhilPapers project.

Mr. Eccles Presents | Science Salon: Dr. Susan Blackmore

Dr. Susan Blackmore is no stranger to skeptics. Dr. Shermer has known Dr. Blackmore since the early 1990s. When the Skeptics Society and Skeptic magazine were founded in 1992 she was already a rock star in the skeptical movement, having moved from believing in the paranormal, ESP, telepathy, and all the rest, to being an arch skeptic of all such claims. After earning a Ph.D. in the paranormal she devoted a decade to testing various phenomena under rigorous laboratory conditions, and continually found null results. That is, the tighter the controls she implemented and the more rigorous the research protocols, the weaker the paranormal effects became until they disappeared entirely. She went on from there to develop a theory about the neural correlates of such altered states of consciousness as Out of Body Experiences and Near Death Experiences, and after that wrote her bestselling book The Meme Machine, in which she developed a theory of how memes can be replicated and selected in a manner first proposed by Richard Dawkins in The Selfish Gene, when he coined the term.

Dr. Blackmore went on to publish one of the leading textbooks on consciousness and is now working on a theory of tremes, or technological memes and how they can be replicated and selected in machines without human input.

This interview was recorded on November 7, 2018 as part of the Science Salon series of dialogues hosted by Michael Shermer and presented by The Skeptics Society, in California.

Mr. Eccles Presents | Thought, Language, and How to Understand the Brain

Language comes naturally to us, but is also deeply mysterious. On the one hand, it manifests as a collection of sounds or marks on paper. On the other hand, it also conveys meaning – words and sentences refer to states of affairs in the outside world, or to much more abstract concepts. How do words and meaning come together in the brain?

David Poeppel is a leading neuroscientist who works in many areas, with a focus on the relationship between language and thought. We talk about cutting-edge ideas in the science and philosophy of language, and how researchers have just recently climbed out from under a nineteenth-century paradigm for understanding how all this works.

David Poeppel is a Professor of Psychology and Neural Science at NYU, as well as the Director of the Max Planck Institute for Empirical Aesthetics in Frankfurt, Germany. He received his Ph.D. in cognitive science from MIT. He is a Fellow of the American Association of Arts and Sciences, and was awarded the DaimlerChrysler Berlin Prize in 2004. He is the author, with Greg Hickok, of the dual-stream model of language processing.

Cannabis and Psychosis | C0nc0rdance

I don’t use cannabis, never have, and probably never will due to possible interference with my treatment plan and exacerbation of my condition. But I thought that this was interesting, relevant, and worth embedding here.

The narrator suggests checking out the studies he references yourselves, and fairly examining the evidence offered.
