#50: To Persuade is Human?
In 2019, IBM introduced the world to Project Debater: an AI system that could go up against humans to debate anything. In this episode, we trace Project Debater’s growth from just an idea to a fully fledged piece of technology and the public debates it’s engaged in. And it raises a bigger question: is persuasion a fundamentally human ability or is it really something that machines are capable of?We hear from IBM engineer and project leaders Noam Slonim, expert debaters Harish Natarajan, Dan Zafrir, and Noa Ovadia, communication neuroscientist Elisa Baek, and best-selling author Daniel Pink.To learn more about Project Debater, visit IBM’s Project Debater website and watch this great mini documentary about the system.

#49: Inoculating Against Persuasion with Josh Compton
Josh Compton studies how “inoculating” people against persuasion can make them more resistant to arguments they encounter later. Dr. Compton is an associate professor of speech at Dartmouth and has written a lot about “inoculation theory,” which began (as a theory) back in the 60s with the work of William McGuire. We talk about lots of inoculation theory’s many extensions and applications.Things we mention in this episode:The “virgin-soil epidemic” explanation of disease spread among indigenous people following Columbus’ voyage to the Americas. (See this Atlantic article by Ostler, 2020)William McGuire’s original formulation of “inoculation theory” (McGuire, 1964)A lot of the work Josh discusses is reviewed in Compton et al. (2021) and Compton (2021).Online games that help inoculate against fake news: “Bad News”, “Breaking Harmony Square”, and “Go Viral!” For a transcript of this episode, go to: http://opinionsciencepodcast.com/episode/inoculating-against-persuasion-with-josh-compton/Check out my new audio course on Knowable: "The Science of Persuasion."Learn more about Opinion Science at http://opinionsciencepodcast.com/ and follow @OpinionSciPod on Twitter.For a transcript of this episode, visit this episode's page at: http://opinionsciencepodcast.com/episodes/Learn more about Opinion Science at http://opinionsciencepodcast.com/ and follow @OpinionSciPod on Twitter.

#47: Moral Foundations & Political Opinion with Jesse Graham
Jesse Graham studies human morality and what it means for our political opinions. He’s an Associate Professor of Management at the Eccles School of Business at the University of Utah. As a graduate student with Jonathan Haidt, he helped develop Moral Foundations Theory (MFT), which has gone on to be a massively influential theory of morality and how it develops. One of Jesse’s key insights was that these moral foundations help explain the divides between liberal and conservative people, which has implications for all kinds of political opinions and pressing topics like political polarization.In our conversation, Jesse fills us in on the early days of his research and the development of MFT over time, walks through the implications of MFT for political ideology, and reflects on where the theory is now.Things that come up in this episode:Divisions between liberal and conservatives: antipathy (Iyengar et al., 2019), geographic segregation (Motyl et al., 2014), avoiding each other’s opinions (Frimer, Skitka, & Motyl, 2017), and even shorter Thanksgiving dinners (Chen & Rohla, 2018; Frimer & Skitka, 2020)Jonathan Haidt’s “Social Intuitionist Model” of morality (Haidt, 2001)Moral Foundations Theory (Graham et al., 2013; for a useful overview, check out MoralFoundations.org)Values beyond the moral (Schwartz, 1992)How adult political leanings can be predicted from observations of them as kids (Block & Block, 2006)Ideology and geographic preferences (Motyl et al., 2020)Moral foundations and the basis of vaccine attitudes (Amin et al., 2017; Karimi-Malekabadi et al., 2021), needle exchange attitudes (Christie et al., 2019), and a variety of political attitudes including abortion (Koleva et al., 2012)For a transcript of this episode, visit: http://opinionsciencepodcast.com/episode/moral-foundations-political-opinion-with-jesse-grahamCheck out my new audio course on Knowable: "The Science of Persuasion."Learn more about Opinion Science at http://opinionsciencepodcast.com/ and follow @OpinionSciPod on Twitter.For a transcript of this episode, visit this episode's page at: http://opinionsciencepodcast.com/episodes/Learn more about Opinion Science at http://opinionsciencepodcast.com/ and follow @OpinionSciPod on Twitter.

#45: How Kids Judge with Larisa Heiphetz
Larisa Heiphetz studies how kids think about religion and morality. She’s an assistant professor of psychology at Columbia University where she runs the Columbia Social and Moral Cognition Lab. As a new dad, I’ve been thinking about how young kids form opinions—do they even form opinions at all? So I was curious to talk with Larisa about her work on how kids make different kinds of judgments and think about their new social worlds. If your interested in participating yourself (or your young child!) in Dr. Heiphetz’s research, you can sign up for studies here: https://columbiasamclab.weebly.com/childstudysign-up.html Things we mention in this episode:Developmental psychology as a research tool to understand big questions (see Heiphetz, 2014)How we think of moral as different from facts and preferences (e.g., Heiphetz et al., 2013, 2014, 2017)Research on how kids evaluate “helpers” and “hinderers” (e.g., Hamlin & Van de Vondervoort, 2018).Psychological “essentialism” and why kids tend to think that way (Heiphetz, 2020)For a transcript of this episode, visit: http://opinionsciencepodcast.com/episode/how-kids-judge-with-larisa-heiphetz/Check out my new audio course on Knowable: "The Science of Persuasion."Learn more about Opinion Science at http://opinionsciencepodcast.com/ and follow @OpinionSciPod on Twitter.For a transcript of this episode, visit this episode's page at: http://opinionsciencepodcast.com/episodes/Learn more about Opinion Science at http://opinionsciencepodcast.com/ and follow @OpinionSciPod on Twitter.

#44: The Contact Hypothesis
How can we make the world less prejudiced? Research from the social sciences hints at a promising solution. This week, we do a deep dive on “The Contact Hypothesis”: what it is, how we know it works, and what its limits are.We hear from four experts in this area whose research sheds light on the question:Tom Pettigrew, emeritus professor of psychology at University of California, Santa CruzLinda Tropp, professor of social psychology at University of Massachusetts-AmherstShreya Bhattacharya, economist; PhD from the University of HoustonSalma Mousa, assistant professor of political science at Yale University For a transcript of this episode, fully annotated with references, go to: http://opinionsciencepodcast.com/episode/the-contact-hypothesis/ Check out my new audio course on Knowable: "The Science of Persuasion."Learn more about Opinion Science at http://opinionsciencepodcast.com/ and follow @OpinionSciPod on Twitter.

#43: Values with Greg Maio
Greg Maio studies human values. He’s a professor of psychology at the University of Bath in England.* He also co-wrote the popular textbook, The Psychology of Attitudes and Attitude Change, and in 2016, his own book came out called The Psychology of Human Values. In our conversation, he shares his work on what values are and why they’re so important. We talk about when values guide or choices (and when they don’t), how people have a hard time articulating their values, and how we can design interventions around the values that people can come together on.*In my intro for this episode, I mistakenly said the University of Bath was in Wales. It is actually in England. Greg was at Cardiff University for years before recently moving to Bath, and Cardiff is in Wales. Sorry for the mixup! Some things we mention in this episode:What are values? (See this useful online article by Dr. Maio.)How do values work and how has the science on this evolved? (see Maio, 2010)How values can act as “truisms” that make them hard to defend (Maio & Olson, 1998; Bernard, Maio, & Olson, 2003; 2005)Values can contribute unity on otherwise divisive issues (e.g., Wolf, Haddock, Manstead, & Maio, 2020) Check out my new audio course on Knowable: "The Science of Persuasion."For a transcript of this episode, visit: http://opinionsciencepodcast.com/episode/values-with-greg-maio/ Learn more about Opinion Science at http://opinionsciencepodcast.com/ and follow @OpinionSciPod on Twitter.

#42: Thinking with Richard Nisbett
Richard E. Nisbett has spent his career studying how people think. He is an emeritus professor of Psychology at the University of Michigan, and his research has influenced how psychologists think about reasoning, introspection, culture, and intelligence. He has written several important books over his career, including The Geography of Thought: How Asians and Westerners Think Differently…and Why and Mindware: Tools for Smart Thinking.His newest book is Thinking: A Memoir.In this episode, Nisbett shares samples of his work relating to our inability to know the inner workings of our own minds, whether we can call various cognitive biases “errors” in reasoning, and how culture shapes the way we interact with the world.Some things that come up in this episode:Nisbett’s favorite study: Norman R. F. Maier’s finding that people fail to understand where their insights come from (Maier, 1931)The classic set of studies by Richard Nisbett and Tim Wilson on our failure to introspect on cognitive processes (Nisbett & Wilson, 1977)The study where a goat entered a classroom (but that was really about intrinsic versus extrinsic motivation; Lepper, Greene, & Nisbett, 1973)Nisbett’s work on errors in reasoning (Nisbett & Ross, 1980; Nisbett, 1992)Early work by Hazel Markus and Shinobu Kitayama on the effects of culture on how we think about ourselves (Markus & Kitayama, 1991; also see Markus’ book Clash!)The “Culture of Honor” (Nisbett, 1996)Cross-cultural differences in analytic versus holistic thinking (see Nibsett’s Geography of Thought for a summary)For a transcript of this episode, visit: http://opinionsciencepodcast.com/episode/thinking-with-richard-nisbett/---------------Check out my new audio course on Knowable: "The Science of Persuasion."Learn more about Opinion Science at http://opinionsciencepodcast.com/ and follow @OpinionSciPod on Twitter.For a transcript of this episode, visit this episode's page at: http://opinionsciencepodcast.com/episodes/Learn more about Opinion Science at http://opinionsciencepodcast.com/ and follow @OpinionSciPod on Twitter.
