Rationally Speaking #170 - Will Wilkinson on "Social justice and political philosophy"
How did "social justice" come to mean what it does today? This episode features a chat with Will Wilkinson, a writer, political philosopher, and vice president of policy for the Niskanen Institute. Will and Julia discuss the libertarian reaction to social justice, whether or not social justice is a zero-sum game, and how the Internet exacerbates conflicts over social justice.

Rationally Speaking #169 - Owen Cotton-Barratt on "Thinking About Humanity's Far Future"
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?

Rationally Speaking #168 - Don Moore on "Overconfidence"
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."

Rationally Speaking #167 - Samuel Arbesman on "Why technology is becoming too complex"
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.

Rationally Speaking #166 - Eric Schwitzgebel on "Why you should expect the truth to be crazy"
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.

Rationally Speaking #165 - Robert Frank on "Success and Luck"
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?

Rationally Speaking #164 - James Evans on "Using meta-knowledge to learn how science works"
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.

Rationally Speaking #163 - Gregg Caruso on "Free Will and Moral Responsibility"
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']
Rationally Speaking #162 - Sean Carroll on "Poetic Naturalism"
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.

Rationally Speaking #161 - Tom Griffiths and Brian Christian on "Algorithms to Live By"
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.

Rationally Speaking #160 - Live at NECSS -- Jacob Appel on "Tackling bioethical dilemmas"
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']
Rationally Speaking #159 - Colin Allen on "Do fish feel pain?"
In this episode Julia talks with philosopher of cognitive science Colin Allen about whether fish can feel pain. In the process they explore a cluster of related questions: Are fish conscious, and how could we tell? What's the difference between pain and suffering? And are there evolutionarily adaptive reasons why animals would have the subjective experience of pain, as opposed to just instinctive reflexes to avoid potentially harmful stimuli?

Rationally Speaking #158 - Dr. George Ainslie on "Negotiating with your future selves"
Ever make a plan to diet, or exercise, or study, and then -- when the scheduled hour rolls around -- decide, "Nah, I'll just put it off another day"? If you said "no," I don't believe you! This episode features behavioral psychiatrist (and economist) George Ainslie, who demonstrated the existence of this ubiquitous phenomenon in human willpower, called hyperbolic discounting, in which our preferences change depending on how immediate or distant the choice is. George and Julia discuss why hyperbolic discounting exists, and how it can be modeled as a negotiation between your current self and your future selves. In the process they explore some of the benefits and risks of this "intertemporal bargaining" approach to willpower, and how it relates to philosophical thought experiments such as the Prisoner's Dilemma and Kavka's Toxin.

Rationally Speaking #157 - Dr. Herculano-Houzel on "What made the human brain special?"
For centuries, scientists have wondered what makes humans so much smarter than other species. Some proposed it was the size of our brain (though that didn't explain why whales weren't smarter than us); others thought it was the size of our brain relative to our body size (but there were problems with that explanation as well). In this episode, neuroscientist Suzana Herculano-Houzel lays out the mystery of the "Human advantage," and explains how a new technique she invented several years ago has shed light on some of these longstanding mysteries.

Rationally Speaking #156 - David McRaney on "Why it’s so hard to change someone’s mind"
You're probably already aware that it's hard to change someone's mind with logical arguments and evidence, especially about emotionally charged topics. But are there exceptions? David McRaney, bestselling author of "You Are Not So Smart" (and host of the blog and podcast by the same name) describes his experiences with people who have done an about-face on some important topic, like 9/11 conspiracy theories. He and Julia discuss a technique for changing someone's mind with evidence, how individual mind-change mirrors scientific progress, and what happens when you confront Trump fans with facts that contradict their narrative.

Rationally Speaking #155 - Uri Simonsohn on "Detecting fraud in social science"
He's been called a "Data vigilante." In this episode, Prof. Uri Simonsohn describes how he detects fraudulent work in psychology and economics -- what clues tip him off? How big of a problem is fraud relative to other issues like P-hacking? And what solutions are there? Sped up the speakers by ['1.0', '1.0', '1.0']
Rationally Speaking #154 - Tom Griffiths on "Why your brain might be rational after all"
You've probably heard about cognitive biases -- the systematic errors human brains make when we try to reason or make decisions. But what if our biases are actually a sign of rationality? This episode features Tom Griffiths, professor of cognitive science at University of California, Berkeley and the director of the Computational Cognitive Science lab. Tom makes the case for why our built-in reasoning strategies might be optimal after all. Sped up the speakers by ['1.14', '1.0']
Rationally Speaking #153 - Dr. Vinay Prasad on "Why so much of what we 'know' about medicine is wrong"
We like to think of doctors as experts, whose recommendations are backed up by solid evidence. So why does it keep happening that a widely used medical intervention -- like estrogen replacement therapy, or heart stents -- turns out to be useless, or even harmful? This episode features Dr. Vinay Prasad, author of "Ending Medical Reversal: Improving Outcomes, Saving Lives," who talks with Julia about why medical research is so often fatally flawed, and what we can do about it. Sped up the speakers by ['1.15', '1.0']
Rationally Speaking #152 - Dan Fincke on "The pros and cons of civil disagreement"
Julia invites philosopher and blogger Dan Fincke onto the show, inspired by a productive disagreement they had on Facebook. Their topic in this episode: civility in public discourse. Do atheists and skeptics have a responsibility to be civil when expressing disagreement, and does that responsibility vary depending on who their target is? Is there a legitimate role for offensive satire? And might there be downsides to civility? Dan and Julia also revisit the subject of their original disagreement: the recent NECSS decision to rescind Richard Dawkins' speaking invitation, on account of a video he tweeted which compared feminists to Islamists. Dan and Julia attempt to put the Dawkins case study in the broader context of the civility debate, asking questions like: What makes something offensive, and can someone be *unjustifiably* offended?

Rationally Speaking #151 - Maria Konnikova on "Why everyone falls for con artists"
You've probably heard about victims of con artists -- like the people who hand over their life savings to sketchy gurus or psychics, or the people who wire thousands of dollars to a "Nigerian prince" who just needs some help getting his far bigger fortune to you. And you've probably thought to yourself, "What a sucker. I'd never fall for something like that." But are you sure? In this episode of Rationally Speaking, Julia interviews Maria Konnikova, science journalist and author of "The Confidence Game: Why we fall for it... Every time," who explains why con artists are so effective that even the best of us are vulnerable. Along the way, they explore questions like: Why do people refuse to believe they've been conned? Are con artists getting more sophisticated over time? And how do con artists view themselves -- do they rationalize their actions, or are they impassive sociopaths?
