Rationally Speaking #23 - Carol Tavris on Everybody Making Mistakes, Except Us... Dec 05, 2010

Show notes

Our guest, Carol Tavris discusses her book (co-authored with Elliot Aronson) "Mistakes Were Made (But Not by Me): Why We Justify Foolish Beliefs, Bad Decisions, and Hurtful Acts." In it they describe how our powerful cognitive dissonance engine of self-justification gives us the incredible ability to rationalize events and beliefs so that we always end up being better than average at being right. Also, how we are forced into these rationalizations by our absolute need to somehow square our most dearly held opinions of ourselves with the nasty tendency of some facts to contradict them.

Carol Tavris is a social psychologist who has tought at UCLA. She has written for many publications, including the NY Times and the LA Times. She is the author of a number of books, including "The Mismeasure of Women" and the recently re-released, "Psychobabble and Biobunk."

Rationally Speaking #22 - Steven Novella on Lies, Damned Lies, and Medical Science Nov 21, 2010

Show notes

Our Guest, Dr. Steven Novella discusses a recent article in The Atlantic in which researcher John Ioannidis shows that 40% of papers published in top medical journals are either wrong or make exaggerated claims (and those are the top journals!). He also discusses the difference between Science and Evidence based medicine. Also, Zombies: are they epidemiologically possible?

Steven Novella is an academic clinical neurologist at the Yale University School of Medicine. He is the host of the Skeptics Guide to the Universe podcast, author of the Neurologica blog, and co-editor of the Science Based Medicine blog.

Rationally Speaking #21 - Joshua Knobe on Experimental Philosophy Nov 07, 2010

Show notes

Our guest, Joshua Knobe, is a philosopher interested in cognitive science, so interested, in fact, that he has contributed to establishing a whole new branch of inquiry known as experimental philosophy — and he plausibly claims that the name is not actually an oxymoron!

The idea is summarized in this way on one of the major web sites devoted to the enterprise: "Experimental philosophy, called x-phi for short, is a new philosophical movement that supplements the traditional tools of analytic philosophy with the scientific methods of cognitive science. So experimental philosophers actually go out and run systematic experiments aimed at understanding how people ordinarily think about the issues at the foundation of the philosophical discussion."

Joshua Knobe is an assistant professor at Yale University, affiliated both with the Program in Cognitive Science and the Department of Philosophy . Most of his work involves using the kinds of experimental methods associated with cognitive science to address the kinds of questions associated with philosophy.

Rationally Speaking #19 - Brendan Nyhan on False Beliefs that Refuse to Die Oct 10, 2010

Show notes

Ever notice how some beliefs only seem to become stronger, even as they're repeatedly debunked? For example, the belief that Barack Obama is a Muslim, or that Bush banned all stem cell research in the country. Brendan Nyhan tells about what he's learned from his research studies and his experience maintaining Spinsanity, a watchdog blog monitoring political misinformation. Is there any hope of clearing up false beliefs if denials simply make the problem worse? Brendan does offer hope, but it won't be easy.

Brendan Nyhan is a a Robert Wood Johnson Scholar in Health Policy Research at the University of Michigan. He received a Ph.D. from the Department of Political Science at Duke University in May 2009. In 2011, He will join the Department of Government at Dartmouth College as an assistant professor. His research focuses on political scandal and misperceptions. He also conducts research on social networks and applied statistical methods.

Rationally Speaking #18 - Evolutionary Psychology Sep 26, 2010

Show notes

You've heard the claims: men are inclined to cheat on women because natural selection favors multiple offspring from multiple mates, especially if you don't have to pay child support. Even rape has been suggested to be the result of natural selection in favor of "secondary mating strategies" when the primary ones fail. Welcome to evolutionary psychology, a discipline curiously situated at the interface between evolutionary science and pop psychology, where both wild and reasonable claims seem to clash against the wall of an incredible scarcity of pertinent data.

The issue is not whether it makes sense to apply evolutionary principles to the study of human behavior. Of course it does, human beings are no exception to evolution. But the devil is in the details, and the details deal with the complexities and nuances of how exactly evolutionary biologists test adaptive hypotheses, as well as with the nature of historical science itself.

Rationally Speaking #17 - Transhumanism Sep 12, 2010

Show notes

What's so great about being human, anyway? The transhumanist movement -- epitomized by organizations like Humanity+ and blogs like Accelerating Future -- advocate the pursuit of technologies to fundamentally change the human condition, tinkering with our brain, bodies and genomes to make ourselves smarter, stronger, happier, and longer-lived.

But many people worry that tampering with human nature could have dire consequences for individuals and society alike. In Our Posthuman Future, political theorist Francis Fukuyama sums up the position of the bioconservatives when he warns that new technologies may "in some way cause us to lose our humanity -- that is, some essential quality that has always underpinned our sense of who we are and where we are going," he writes. In this episode of Rationally Speaking, Massimo and Julia ask, first, are the goals of transhumanism realistic, and second, are they desirable?

Rationally Speaking #16 - Deferring to Experts Aug 29, 2010

Show notes

At a talk he gave at TAM 8, Massimo argued that non-experts in a field aren't qualified to reject an expert consensus, such as that on anthropogenic climate change. Most recently, he has taken Jerry Coyne to task for making a philosophical argument without having the necessary expertise. This raises a number of questions: Are there fields that have no experts, or that have pretend experts? If there is a lot of disagreement among experts on a topic, should we take any individual expert's opinion less seriously? How much consensus is required before a non-expert should say, "OK, looks like this question really is settled"?

Perhaps noted expert George Carlin had it right when he said: "I have as much authority as the pope, I just don't have as many people who believe it."

Rationally Speaking #15 - Q&A With Massimo and Julia Aug 15, 2010

Show notes

In the first of what we hope will be a regular feature of Rationally speaking, Massimo and Julia answer listeners' questions. These range from what are M & J's sacred cows, to how we should approach morally repugnant claims made by venerated philosophers, to whether we are deluding ourselves believing that our votes count.

Rationally Speaking #14 - Jennifer Michael Hecht on Science, Religion, Happiness, and Other Myths Aug 01, 2010

Show notes

Author, science historian, philosopher, and poet Jennifer Michael Hecht discusses her views on science, religion, and skepticism. She talks about her book "The Happiness Myth", showing how the very concept of happiness has changed dramatically both in time and across cultures, to the point that it may make little sense to simply ask "are you happy"? Also she makes her skeptical comments on the findings of science, for instance concerning eating and exercise habits, and how the skeptic community's reliance on science borders on religion.

Jennifer teaches at the New School in New York City. She is the author of Doubt: A History: The Great Doubters and Their Legacy of Innovation from Socrates and Jesus to Thomas Jefferson and Emily Dickinson and of The Happiness Myth: The Historical Antidote to What Isn't Working Today, among other books.
