This week's episode is a bit different. Please enjoy a talk from Timothy Caulfield that originally aired on Skeptical Inquirer Presents. SIP is a live online series of talks from some of the brightest minds in the reality based community and is just one of the many great shows that the Center for Inquiry produces. This recent episode of the series featured Timothy Caulfield where he was presented with the Robert P. Balles Annual Prize in Critical Thinking. Afterwards, Caulfield gave an informative talk on the state of the infodemic of misinformation, what we've learned, and ways to deal with the problem. It was something we thought fans of Point of Inquiry would enjoy! The spread of misinformation seems to intensify with each passing week. From social media to cable news to popular podcasts, science-free bunk is everywhere. The ongoing “infodemic” is doing tangible harm to public health, public discourse, and public trust. So...what can we do about it? Timothy Caulfield is the bestselling author of Is Gwyneth Paltrow Wrong about Everything? and host of the acclaimed Netflix documentary series A User’s Guide to Cheating Death.

In this week's episode, we are diving into the flat-earth conspiracy theory and why people could believe such a thing with guest Kelly Weill and her new book, Off the Edge. In 2019 Jim Underdown and the CFI Investigations Group produced a video where they designed a series of experiments to show that the earth is indeed not flat. CFIIG's conducted their experiment in front of over a dozen flat-earthers. Even in the face of conflicting evidence to their own beliefs, the flat-earthers held firm in their claims. Underdown and Weill speak about her new book, the history of the flat-earth conspiracy dating back to the 1830s, and the desire to belong to a community, which Weill saw as a reason some flat-earthers join the movement. Also, the role media and emerging technologies play in helping conspiracists spread their messages. You can also read Weill's piece in the Atlantic on the book and flat-earthers. Kelly Weill is a journalist at the Daily Beast, where she covers extremism, disinformation, and the internet. As a leading media voice on the role of online conspiracy theories in current affairs, she has discussed Flat Earth and other digital fringes on ABC's Nightline, CNN, Al Jazeera, and other national and international news outlets.

What does it mean to be alive? Does life have a clear definition? On this week's episode, Carl Zimmer joins host Jim Underdown to discuss his new book, Life's Edge: The Search for What It Means to Be Alive to help answer those questions. Can we clearly define what it means to be alive? Scientists have been struggling with this question for centuries. For every rule or idea that's brought to the table, it seems a new species of plant or animal comes along that turns the whole thing on its head. For example, tardigrades, everyone's favorite microorganisms, are able to put themselves into a kind of suspended animation that stops their metabolization. Are they alive or dead at that point? Zimmer speaks about tardigrades and their special cryptobiosis, the intelligence of slime molds, and where viruses fit in the question of life. Carl Zimmer is an award-winning New York Times columnist and the author of fourteen books about science. His newest book is Life’s Edge: The Search for What It Means to Be Alive  (hardcover, Kindle, or audio.) You can find Zimmer on twitter @carlzimmer.

Christians believe that Jesus was the son of God who walked the Earth as a human being. Some Atheists believe none of the God bits but that there was a man named Jesus who did exist. There is also an ever growing community who believe Jesus did not exist at all. Not as the son of God nor as a man. On today's episode we speak to someone with evidence to support the claim of Jesus never existing. Duke Mertz joins host Jim Underdown to speak about his work on the subject of Jesus namely his Free Inquiry article, The Quest for the Mythical Jesus. They speak about what led Duke to undergo his research into this controversial topic as they dive into the substance of Mertz's claims. Core to these claims is the story of Christ fundamentally serves as a passion drama for the time. Mertz also provides details on the inaccuracies found throughout the holy text.

Throughout the modern world trust in science has continued to erode at dangerous speeds. From anti-vaxxers to climate change deniers, there is an ever growing movement of people that deny science at the peril of us all. The shift towards a public with increasing lack of scientific literacy and critical-thinking skills combined with the proliferation of online misinformation and disinformation and social media algorithms that reinforce ingrained worldviews has caused a situation that is out of control. On this episode of Point of Inquiry we speak with Gale Sinatra and Barbara Hofer on their new book, Science Denial: Why It Happens and What to Do About It. Sinatra and Hofer speak about their decades of research and work on science, scientific literacy, and how humans think and acquire knowledge, how "doing your own research" is explicitly not simply conducting a Google search. They also go into some of the psychological explanations for why people deny science and what everyone can do to help stem the tide. Gale M. Sinatra is the Stephen H. Crocker Professor of Education and Psychology at the Rossier School of Education at the University of Southern California, where she directs the Motivated Change Research Lab.

Have you ever been curious about what other people believe in or how they navigate the ethical challenges of life? Ancient philosophy was partly used as a way to better understand the best way to live life.  In this episode of Point of Inquiry, Jim Underdown talks to two of the editors of How to Live a Good Life: A Guide to Choosing Your Personal Philosophy. The book is a collection of essays by fifteen philosophers describing what it means to live according to a philosophy of life. These philosophies range from Eastern traditions like Daoism, Confucianism, and Buddhism, Western beliefs like Stoicism, and contemporary philosophies such as existentialism and effective altruism.   Massimo Pigliucci and Skye Cleary, who also wrote chapters for the book, discuss the book, what led to its creation, their specialties of Stoicism and Existentialism (respectively.), and how they incorporate their philosophical beliefs in their day to day lives. The book and this interview provide a beginner’s guide on choosing a philosophy and ways to live those beliefs out in the real world. Massimo Pigliucci is the K.D. Irani Professor of Philosophy at the City College of New York and was formerly a biology professor at Stony Brook University. His research interests include the philosophy of biology, the relationship between science and philosophy, the nature of pseudoscience, and the practical philosophy of Stoicism. Skye C.

A question on the minds of many theists and non-theists alike is why are so many Americans leaving religion and becoming religiously unaffiliated? What are the underlying factors causing this shift? In today's episode we dive into what the data shows about this movement with Ryan Burge, author of the new book The Nones: Where They Came From, Who They Are, And Where They Are Going (Fortress Press, 2021). Ryan speaks about how the field of social science is changing with the improvements made to surveying, the underlying causes moving people to become less religiously affiliated, unpacking why America has been so historically religious compared to other countries, how religious economy theory fits into this the rise of the nones, and the role the internet has played in shifting people away from religion. Ryan Burge is an Assistant Professor of Political Science and Graduate Coordinator at Eastern Illinois University and a pastor in Mt. Vernon, Illinois.

In the June/July issue of Free Inquiry, today's guest Greg Paul makes the case that a loving God cannot possibly exist next to all the suffering and death, children have had to endure throughout human history. In his piece, he claims this fact has the, "...potential to accelerate the already rapid decline of the illusion that is theism." On today's episode we speak with Greg Paul on what lead him to start looking into this idea, some of the various factors causing the decline of religion throughout the world, what happened after he published his findings in the Philosophy & Theology journal, and the link he sees between the religious right's stance against abortion and their hypocrisy.
