Rationally Speaking #163 - Gregg Caruso on "Free Will and Moral Responsibility"

What can we do now to affect whether humanity is still around in 1000 years (and what life will be like then)? In this episode, Julia talks with Owen Cotton-Barratt, a mathematician at Oxford's Future of Humanity Institute. They cover questions like: Given our poor track record of forecasting, is there any point to speculating about the far future? And is it rational to prioritize current people over future people?  Sped up the speakers by ['1.0', '1.16']

This episode features a chat with Don Moore, professor of management of organizations at the University of California Berkeley's Haas School of Business, and an expert in overconfidence. Don and Julia discuss the various forms of overconfidence, whether its upsides are big enough to outweigh its downsides, and what people mean when they insist "I think things are better than they really are."  Sped up the speakers by ['1.13', '1.0']

As the technology we rely on every day becomes increasingly sophisticated, it's getting to the point where it's too complicated to understand -- not just for individual users, but for any human at all. In this episode, Julia talks with complexity scientist Samuel Arbesman, about his new book Overcomplicated: Technology at the Limits of Comprehension, why these unprecedented levels of complexity might be dangerous, and what we should do about it.  Sped up the speakers by ['1.18', '1.0']

Some theories violate common sense so wildly that you want to just reject them out of hand. For example, "The United States is conscious," or "The most moral act would be to replace all living beings with an orgasmic blob." On the other hand, many theories in physics that sounded similarly crazy turned out to be very well-supported (think of quantum theory, or relativity). So what role should "common sense" play in evaluating new theories? This episode features a discussion with philosopher Eric Schwitzgebel on his theory of "Crazyism," that we should expect the truth to be at least a little bit crazy.  Sped up the speakers by ['1.0', '1.04']

If someone asks you, "What caused your success (in finance, your career, etc.)?" what probably comes to mind for you is a story about how you worked hard and made smart choices. Which is likely true -- but what you don't see are all the people who also worked hard and made smart choices, but didn't succeed because luck wasn't on their side. In this episode, Julia chats with professor of economics Robert Frank about his latest book, Success and Luck: The Myth of the Modern Meritocracy. They explore questions like: Why do we discount the role of luck in success? Has luck become more important in recent years? And would acknowledging luck's importance sap our motivation to try?  Sped up the speakers by ['1.0', '1.15']

Has science gotten slower over the years? Does the proliferation of jargon make it harder for scientists to collaborate? What unstated assumptions -- "ghost theories" -- are shaping our research without us even realizing it? In this episode of Rationally Speaking Julia talks with sociologist of science James Evans, who investigates questions like these using some clever data mining.  Sped up the speakers by ['1.0', '1.15']

If people don't have free will, then can we be held morally responsible for our actions? And what would happen to society if we were to collectively shed our belief in free will? In this episode Julia talks with philosopher Gregg Caruso, who advocates a position of "optimistic skepticism" on the topic. Skepticism because people don't have free will as a sense of moral responsibility, but optimistic because society would be better off if we accept that we do.  Sped up the speakers by ['1.0', '1.06']

Naturalism is the stance that everything that exists in the universe arises from "natural" causes, of the sort observable by science -- not supernatural ones. It's practically a foundational tenet of skepticism. But does it imply that there can be no meaning, or purpose, or morality in the universe? This episode features physicist Sean Carroll, author of the recent bestseller The Big Picture: on the Origins of Life, Meaning and the Universe Itself. Sean and Julia talk about the new "ism" he introduces in the book, "poetic naturalism," and how it attempts to resolve the apparent conflict between science on the one hand, and things like morality, free will, consciousness, and meaning on the other.  Sped up the speakers by ['1.1', '1.0']

Julia chats with the authors of Algorithms to Live By, about how to apply key algorithms from computer science to our real life problems. For example, deciding which apartment to rent, planning your career, and prioritizing your projects. In the process, they discuss the assumptions that underlie those algorithms (and what to do about the fact that those assumptions are inevitably violated by the messy real world), and why procrastination might actually be the right algorithm for the wrong problem.  Sped up the speakers by ['1.11', '1.2', '1.0']

It's the annual live Rationally Speaking episode, taped at the Northeast Conference on Science and Skepticism in NYC! This year features returning guest Jacob Appel, a bioethicist (and lawyer, and psychiatrist). Jacob and Julia discuss various bioethical dilemmas, such as: How do you handle parents who want to withhold medical treatment from their child for religious reasons? Is it unethical for American doctors to test new medications in the third-world? And what kinds of principles does a bioethicist use to justify their decisions, beyond "that's just my personal opinion"?  Sped up the speakers by ['1.0', '1.17']
