Point of Inquiry

Dr. Julia Shaw is a psychological scientist and senior researcher in the Department of Law and Social Science at London South Bank University. She teaches at the undergraduate and graduate level and her research on false memory has been published in several international academic journals. She returns to Point of Inquiry this week to discuss her new book, The Memory Illusion.

Our memories are a collection of perceptions of our past experiences, and they influence what we think we're capable of in the future. Dr. Shaw argues that if we start to question the accuracy of our memories we're then forced to question the foundation of who we think we are. She shows us that our memories aren't as reliable as we think. Not only are we capable of co-opting other people's memories as our own, but we can also be easily persuaded by the power of suggestion that we've committed acts that have never actually occurred. Even when it comes to our most confident recollections, the potential for memory error has proven to be profound, and Dr. Shaw believes understanding the science of memory can help us deal with our brains' tendency to rewrite the past.

Since the beginning of humankind unpredictable forces of nature have been among our most dangerous threats: volcanic eruptions, earthquakes, tsunamis, floods, tornados, hurricanes, and other disasters that trigger our fight-or-flight survival instincts. Pollution invoked climate change is exacerbating natural disasters and spurring unprecedented human migration. So when so many people are clamoring for safety and running for the hills, what does that mean for those who are already atop them?

Author and geographer Barry Vann explains what awaits the future of our planet and its human populations in his new book Forces of Nature: Our Quest to Conquer the Planet. In this fascinating yet sobering conversation with Josh Zepps, Vann elaborates on both the causes of migration as well as the outcomes of the population shifts to come. They discuss both the impact humans have had on our planet, and how our planet affects us in turn. Vann is optimistic that while society is prone to taking the path of least resistance, the conditions brought about by climate change will soon become so unbearable it will force us to make tough decisions that will be crucial for our survival.

Death is an unsettling thing to come to grips with. We know it is inevitable that it will one day happen to us. One of the first things most of us learn about death is that it happens to everyone, yet perhaps because no one ever comes back to tell the tale, there's a lot about our impending doom that's difficult to fully grasp. To help us take comfort in our inexorable demise, we welcome Andrew Stark, an author and political science professor at the University of Toronto.

Having spent time as a policy advisor to the Prime Minister of Canada, he now offers himself as a life advisor – or rather, a death advisor – in his new book The Consolations of Mortality: Making Sense of Death. Stark gives us an overview of what the greatest minds of history have said about what it means to die. With a skeptical eye, he sorts through the various arguments for how we should feel about death, effectively shaking off the sugar coating of mortality in an effort to provide us with solace that stands the test of logic.

Emily Willingham is a journalist, scientist, and award winning skeptical blogger, with much of her work centered on autism and debunking junk science controversies. Recently the autism community has shown a surge in support for medical cannabis, as anti-vaccination activists claim that cannabis may hold the key for a cure, and many people with autism claim it to be a useful for controlling their symptoms. Willingham and host Lindsay Beyerstein delve further into the topic to sort through the misconceptions that exist on both sides of the debate.

Willingham explains that the data is limited on the relationship between cannabis and autism, in part because of the strict research restrictions that have been placed on what the government classifies as a Schedule I substance, a drug with no medical value. Despite the abundance of data showing its benefits and safety in regard to pain relief and inducing appetite, Willingham points out that the stigma against cannabis has lead to restrictions that are even more severe than those that exist on many other pain killers and opioids.

Emily Willingham will also be speaking at the upcoming Women in Secularism conference, September 23-25 in Arlington, VA. For more information go to womeninsecularism.org.

Elizabeth Greenwood teaches at Columbia University and like many other young professionals she has an insurmountable amount of student loan debt. With the overwhelming feeling that she would never escape her debt she desperately longed for a new start. There was no going back on what she had done to accumulate her debt, but perhaps she could skip ahead. She began to investigate what it would take to fake one's own death in the 21st century.

Greenwood was shocked to ​find a robust infrastructure of death fraud all at her fingertips. Eager to know more about the strange subculture, she decided to go through with faking her own death and writes about it in her new book, Playing Dead: A Journey Through The World of Death Fraud. She meets some interesting characters along the way and realizes that a new start might not be as easy and appealing as it sounds.

Bronwen Dickey is a contributing editor at The Oxford American, and author of Pit Bull: The Battle Over an American Icon. Her writing can also be found in The New York Times, The Virginia Quarterly Review, Newsweek, Slate, The San Francisco Chronicle, and numerous other publications. For Dickey's most recent piece, just published in Popular Mechanics, she embarks on the "Conspire-Sea Cruise," giving us an inside look at what the world of a conspiracy theorist is like and what fuels the need to believe in vast, nefarious plots.

Dickey says she was inspired to report on the conspiracy cruise after working on Pit Bull, where she discovered just how strong the desire can be to ignore evidence and seek out junk science that supports one's existing beliefs. In conversation with host Lindsay Beyerstein, Dickey looks at the paranoia that propels people towards conspiracy and compares it to the tireless fear mongering pit bull breeds are subjected to. Dickey gives a detailed account of the history and science behind pit bulls and offers a hardheaded overview of what we know about them as a breed and the contrasting ways everyday Americans view them.

Those following the Olympics this year may have noticed Michael Phelps sporting circular bruises all over his body. That's because Phelps, like many Olympic athletes, won't go after their medals without going after their cups. The growing fad of cupping is an ancient practice in which cups are placed all over the body and skin is suctioned inside the cup, bursting blood vessels and creating circular bruises. The claim is that cupping releases toxins and heals muscle tissue, among a number of other alleged health benefits, none of which can be backed up by scientific evidence.

Dr. David Gorski is a surgical oncologist, blogger, and advocate for evidence-based reasoning. He joins us today to discuss the latest Olympic pseudoscience fads and what it is about them that makes them pseudoscience. He gives his take on why alt-med practices like cupping are so appealing to people, and the best ways to go about persuading people out of them.

Iraqi-born writer Faisal Saeed Al Mutar is a blogger for the Huffington Post and a columnist for the Center for Inquiry's own Free Inquiry magazine. Having grown up in Iraq under the rule of Saddam Hussein, he's now a human rights activist and secularism advocate as well as founder of the Global Secular Humanist Movement and Secular Post.

For Faisal and progressive Muslims and secularists across the globe, social media is the primary means of not only seeking community and acceptance, but to opening dialogues about fraught issues such as dissent from Islam. But recently Facebook seems to be singling out many of these conversations and communities, and shutting them down. In a conversation with Josh Zepps, Faisal gives several examples of Muslims and Arabs having their posts and pages removed. Arab secularist groups, condemnations of the Taliban, and other challenges to Islam are being banned from the site, which is often justified by claims of racism, hate speech, and other alleged violations of "community standards." Faisal argues that when Facebook censors Muslims and Arabs from being able to criticize extremism and terrorism within their own religion and culture it adds to the very stereotypes and fears surrounding Muslims that Facebook should want to prevent.

David Cay Johnston is an award winning investigative journalist and New York Times best-selling author, as well as one of few journalists who has deeply dug into the dirty laundry of Donald Trump, now the Republican nominee for President of the United States. In 1988 Johnston left the LA Times to report on casino gambling in Atlantic City, which resulted in uncovering a detailed history of corruption in Trump's past dealings. The information he began to unearth compelled Johnston to follow Trump's career closely for decades, eventually leading to the release of his newest book, The Making of Donald Trump.

Point of Inquiry host Lindsay Beyerstien talks to Johnston about some of the key insights of his book, including the similarities between Trump and TV psychics, and Trump's astounding ability to deflect any responsibility, and avoid any consequences for his actions.

Free speech on college campuses has become a topic of impassioned debate, as the lines between hate speech and harassment, or peaceful protest and public disturbance, are rather blurry and hotly contested. Particularly since the protest movements of the 1960s, college campuses have long been a kind of testing ground for different norms and boundaries of free expression. At the same time, some institutions of higher learning have speech codes which many feel are serving to silence debate and discussion among students in the name of protecting feelings.

Our guest this week, Wendy Kaminer, is among those who believe that things like speech codes and trigger warnings have gotten out of control. Kaminer is a lawyer and writer who has dedicated much of her life's work to defending free speech. She and host Lindsay Beyerstein engage in a spirited discussion about the grayest areas concerning speech and censorship on campus and in the culture at large.

Kaminer will also be one of the many fantastic speakers at the fourth Women in Secularism conference, September 23-25 in Alexandria, Virgina.
