Rhia Catapano studies what happens when people think of an opinion in terms of what they support versus what they oppose. It turns out that this simple difference carries important implications. Even if we're talking about the same basic opinion, something shifts when it's about support than opposition. In our conversation, Rhia shares her findings and what it means for people who want to communicate more effectively.

At the top of the show, I discuss Issue 1 in Ohio from 2023. Most of the background details for that were drawn from this NYT article.

Demi Oba is an Assistant Professor of Marketing at Harvard Business School. He studies the nature of communication. In our conversation, Demi shares some recent research on the different types of "hedges" people make when expressing uncertainty in a claim. These types of uncertainty matter for how persuasive a person can be. In fact, sometimes, being the right kind of uncertain can be more influential than expressing confidence.

Jae-Hee Jung is an assistant professor at Rice University, where she studies party politics, political behavior, and political psychology in Western democracies. Her research focuses on the strategic use of moral rhetoric (i.e., appeals to fundamental notions of right and wrong) and how it shapes political competition and voter psychology.

We talk about her work analyzing political manifestos, the psychological mechanisms like pride that mobilize a party's base, and the surprising finding that inclusive moral messaging can actually build sympathy across the aisle without causing a partisan backlash. Along the way, we see how framing policies around core principles rather than simple costs and benefits changes the way voters connect with political parties over the long haul.

Dr. Jung's new book is Shared Morals: The Role of Moral Rhetoric in Party Politics.

Elizabeth Dunn and Jiaying Zhao are professors at the University of British Columbia, where they study social psychology and climate behavioral science, respectively. Together, they explore the intersection of human happiness and environmental action, challenging the traditional "guilt and shame" narratives that dominate climate communication. We talk about their new book: Leave the Lights On: How Joyful Decisions Can Save Our Species, which explores how you can address climate change by taking actions that make you feel happy. We see how reframing environmental choices around joy can create a more effective, contagious movement for behavior change.

Yamil Velez is an assistant professor of political science at Columbia University, where he studies what makes political opinions hard to shift. He’s been using innovative new methods to test important ideas about how people arrive at their views and what it takes to change them. We talk about the relationship between beliefs and opinions, why correcting misinformation doesn’t necessarily move opinions, and what happens when persuasive messages are tailored to the specific reasons people hold their views. 

Yamil shares his work using large language models to generate personalized arguments, showing that people will update their beliefs pretty readily—but only some of those belief changes actually translate into attitude change. Along the way, we explore what this means for persuasion, polarization, and the future of using AI to study (and maybe influence) public opinion.

Sylvia Perry is a social psychologist and Associate Professor at Northwestern University, where she directs the Social Cognition and Social Identity Lab. She studies the psychological mechanisms that shape how people recognize and confront their own biases, as well as how those biases are transmitted across generations.

We talk about her research on racial socialization, specifically focusing on how white parents navigate—or frequently avoid—conversations about race with their children. Sylvia shares insights from her research on facilitating parent-child discussions about race and racism. We discuss why color-conscious messaging is more effective than "colorblind" approaches at reducing children’s implicit biases and how addressing subtle microaggressions can be more impactful for a child’s development than discussing overt prejudice alone.

Along the way, we explore the privilege underlying the freedom to opt out of these difficult conversations and offer practical takeaways for parents looking to foster empathy and a sense of fairness in their own homes.

Alex Kustov studies public opinion about immigration—why it’s so durable, why it becomes so politically explosive, and what (if anything) can make it more popular. We talk about the surprisingly stable foundations of immigration attitudes, why only a small fraction of people are categorically opposed, and how partisanship shapes the debate. Alex also explains what he calls the “altruist’s dilemma”: why people who are genuinely altruistic can still be skeptical of immigration, and how policies that are demonstrably beneficial to receiving communities can shift that skepticism. Along the way, we explore what it would mean to design immigration policy not just to be good, but to be visibly and intuitively good to the public.

Dr. Kustov's recent book is In Our Interest: How Democracies Can Make Immigration Popular. He also writes the Substack Popular By Design.

The episode's introduction is from Episode 57: Media, Norms, and Social Change with Sohad Murrar.

I'm excited to share a preview of a new podcast I think you’d enjoy: Mind Games.

What if you could hypnotize yourself into a better you? Or.... secretly hypnotize others into giving you anything you want? That’s the promise of NLP. Mind Games is an investigation into the world of Neuro-Linguistic Programming, or NLP, a blend of hypnosis, linguistics, and psychology that has quietly shaped industries, institutions, and belief systems around the world.

Part science experiment, part investigation, part true crime thriller, Mind Games tells the story of NLP and its crazy cast of disciples, including the fake doctor who invented it at a New Age commune, took it to Fortune 500 boardrooms, and whose gruesome murder trial did little to stop its rise.

Find Mind Games on Apple, Spotify, or wherever you get podcasts. New episodes out Tuesdays.

Steven Rathje is a postdoc at New York University and an incoming assistant professor at Carnegie Mellon University. He studies the psychology of technology, which includes how people engage with a variety of digital tools, especially those with social implications. We talk about his work on what makes content go viral online and the consequences of AI chatbots that are more agreeable than maybe they ought to be. Along the way, we see how basic principles of psychology govern social life in these digital spaces, too.

A few things that come up:

• Lack of change in conspiracy beliefs over time (Uscinski et al., 2022)
• The psychology of virality (Rathje & Van Bavel, 2025)
• Testing the effects of AI sycophancy (Rathje et al., 2025)

Greg Murphy studies the psychology of concepts. How do we use language to understand things, and how do we sort the world into categories? In our conversation, we consider what makes a category, why we love them, and where they steer us wrong.

Dr. Murphy released a book on this topic a few years ago: Categories We Live By
How We Classify Everyone and Everything

Paul Eastwick and Eli Finkel are two social psychologists who study the gears and levers of romantic relationships. What do people find attractive in a partner? How do relationships evolve over time? And critically, do romantic movies get any of this stuff right?

Paul and Eli host the podcast, Love Factually, which dissects popular romantic films from the standpoint of behavioral science. What do they get wrong? What do they get right?

On the show this month, we talk about the podcast, how scientists can study something like human love, and why people don't quite know what they find attractive until they stumble upon it.

Also, at the end of the episode, I mention my print shop, Indispensable Letterpress. Check out the cards and posters I've been making using old technologies. Maybe even pick something up for a friend this holiday season? Be careful, though--your support will tell me that you approve of my obsession with the antiquated machines that fill my basement.

Sara Grady studies the function of entertainment—why we watch, play, and listen to the media that fill our lives. She's an assistant professor of Communication at Ohio State University. In our conversation, we explore what entertainment actually does for us, what it means to connect with fictional characters, and how storytelling shapes our relationships and well-being. Sara also shares her path from film production to media psychology and why understanding stories only deepens their magic.

David Broockman is a political scientist at UC Berkeley who digs into one of democracy’s core questions: can political messages really change minds? He’s spent his career running careful studies of persuasion, from door-to-door conversations to the effects of cable news, and testing whether the confident claims of political consultants actually hold up.

In our conversation, David shares the path that brought him into political science and the “credibility revolution” that reshaped how researchers study politics. We talk about what persuasion looks like in practice, why it’s so hard to predict which messages will work, and what his research reveals about the gap between political insiders’ instincts and what actually moves the needle.

Lulu Miller has done a lot of things and done them very well. She is currently the co-host of Radiolab and its family-friendly spinoff, Terrestrials. She also co-created Invisibilia with Alix Spiegel and wrote the beautiful book, Why Fish Don't Exist. In our conversation, I try to learn Lulu's secrets when it comes it sharing science across media. I've been a fan of her work for a long time, so it was great to get to talk with her!

(If you're here as a Radiolab fan, you should also check out my chat with Latif Nasser a couple of years ago.)

In the show, I mentioned a run of letterpress prints I did inspired by Lulu's book. You can get a print for yourself here and learn more about how they were made. Any sales feed back into the podcast.

Joel Bervell recently graduated from medical school, which is when he gained fame as an influencer helping the public navigate good medical science. He’s out there breaking down myths about medicine, particularly shining a light on racial disparities in health and treatment. He recently won a Peabody award, consults with the White House, has given interviews on various media platforms, and has given talks all over.  He hosts the podcast, The Dose. And he developed an animated children’s show for YouTube ("The Doctor is In"). 

So, I think it’s safe to say Joel knows a thing or two about reaching people with solid science content. I was happy I could catch him in between the 30 things he’s working on to learn more about his story and how he pulls all of this off. So let’s jump right into my chat with Joel Bervell.

Kicking off the 3rd season of Hot SciComm Summer is Adam Cole. Adam started at NPR’s Science Desk in 2011 where he started making short videos and radio pieces. In 2014, he launched the YouTube channel Skunk Bear with NPR, which was a venue for fun, quirky, visual forays into science stories big and small. After NPR, he did work for Vox, including their Netflix series, “The Mind, Explained” in 2019.

Most recently, Adam’s work came on my radar again because he’s one half of the new YouTube channel, Howtown. Fans of SciCommSummer will remember my very first guest back in 2022—Joss Fong. Well, Joss is the other half of Howtown. Together, they’ve been doing really excellent work building an independent channel making long-form videos exploring big questions and the methods scientists use to answer them. It’s so good. You need to check it out if you haven’t yet.

Adam shares his story as a science journalist, the makings of Howtown, the value of having a creative partner, and the pros and cons of working for yourself or a more established institution.

Matt Grizzard is a communication scholar who studies how people relate to characters in entertainment media as a sign of how much they enjoy one story versus another. A guiding framework behind this work is "affective disposition theory." What is that? Well, listen to the episode! We talk about this theory, how it helps us understand people's reactions to what happens to characters in media, and what it means for the importance of entertainment in our everyday experience.

Mohamed Hussein studies how the psychology of persuasion and politics interact. He is an assistant professor of marketing at Columbia Business School. On the podcast, we talk about his work on "receptiveness," or people's openness to hearing out opinions they disagree with. (For more on receptiveness, check out episode 56, Receptiveness to Other Opinions with Julia Minson). But the research we talk about includes studies on how "you" versus "we" language affects how receptive we seem (Hussein & Tormala, 2024) as well as studies showing the costs of being receptive across political party lines (Hussein & Wheeler, 2024).

Kurt Gray studies our moral minds and how we grapple with everyday ethics. In his new book, Outraged, he explores the deep psychology of human nature and what it means for how we navigate politically divisive times. In our conversation, we do a deep dive into his perspective that morality is fundamentally about our ideas of harm, which conflicts with how other theories talk about morality. We also get into what it means for concepts to shift with time or circumstance.

Dr. Richard Petty is a professor of psychology at Ohio State University. He's probably best known for co-developing the Elaboration Likelihood Model (ELM) of persuasion (but he's done a lot of other stuff, too). He was also my advisor in grad school.

In the last episode of Opinion Science, Rich lent his voice to telling the story of the ELM. Go check that out if you haven't already. But my full conversation with Rich was also great and went in a few directions that just didn't fit into a general intro to the ELM. So, I present that full interview here. It gets a little inside baseball at some points, so be aware of that. But it's an interesting glimpse at the random ride that a career in science can be and the number of lucky moments that can steer the wheel.

In the 1980s, two social psychologists--Rich Petty and John Cacioppo--devised a new way to make sense of persuasion: the Elaboration Likelihood Model. Their work came on the heels of an era in psychology when people were fed up with persuasion research. The old studies were a mess, and it wasn't clear if it was even possible to understand how persuasion works. In the course of studying for an exam in graduate school, Rich and John started sketching out some ways to make sense of things. Over the next decade or so, those ideas blossomed into a fully formed theory that continues to inspire persuasion research today.

In this episode, I bring you up to speed on the Elaboration Likelihood Models and the incredible stories of happenstance that made it all happen. The foundation of the episode includes an interview with Rich Petty, a psychology professor at Ohio State University. In the latter half of the episode, we hear from Pablo Briñol, psychology professor at Universidad Autónoma de Madrid. Plus, there are some bonus words from Bob Cialdini.

If you want to dive really deep into the Elaboration Likelihood Model, check out the 1986 chapter in Advances in Experimental Social Psychology (Petty & Cacioppo, 1986). For the updated aspect of the model--"self-validation"--you can check out a recent paper by Pablo and Rich (Briñol & Petty, 2022).

Dave Fleischer is a political organizer who led the team that pioneered “deep canvassing,” which is a particularly effective form of face-to-face persuasion. It was developed on the ground, but when political scientists put it to a rigorous test, they found that these brief conversations with voters were having a lasting impact (Broockman & Kalla, 2016).

On this episode, Dave shares his background in political campaigns and walks us through an actual example of deep canvassing that made a real difference to someone’s attitudes toward transgender people.

If you want to know more, check out Dave’s Substack, where he’s written a lot of great articles about his team’s approach to persuasion.

Also, doing my due diligence, I’ll link to the movie I mentioned in the intro--“Salesman” (1969)--if you want to dive into classic American cinéma verité.

David Halpern is the President & Founding Director of the Behavioral Insights Team. It started as a "nudge unit" in the British government but has gone on to become its own company with offices around the world. We talked to David in 2021 when we were gathering interviews for our podcast series, They Thought We Were Ridiculous: The Unlikely Story of Behavioral Economics. But he had a lot of great insight on the role of behavioral science in public policy, so I wanted to share our full conversation as a standalone episode.

Several years ago, David wrote a great book about the Behavioral Insights Team and what it's learned about applying behavioral science at scale. That book is: Inside the Nudge Unit: How Small Changes Can Make a Big Difference (and I really enjoyed it).

Daniel Kahneman was a titan in social science. He transformed our understanding of decision-making, he taught a generation about social psychology, he won a Nobel prize. It's hard to overstate his influence. He passed away last week, and the field is mourning the loss. Along with the hosts of the podcast Behavioral Grooves, I interviewed Kahneman back in 2021, and we used that interview as a foundation of our podcast series, "They Thought We Were Ridiculous: The Unlikely Story of Behavioral Economics."

I had already been considering releasing the full interview as a standalone episode of Opinion Science, and under the circumstances, it felt like sharing it now was a nice tribute to the man who had contributed so much. I hope listening to this is a comforting and warm reminder of his impact on behavioral science.

This isn't a typical Opinion Science episode, though, because the interview was mostly for research and pulling soundbites. We didn't set out for it to be a polished standalone interview. As a result, we go down rabbit holes, get technical, assume shared knowledge, etc. So, I make no promises that you'll follow every moment of the interview if you're not already familiar with Kahneman's work, but it might still be a fun listen anyway.

Thanks again to Danny Kahneman for reminiscing about the early days of his career with us.

Andy Guess studies how social media platforms shape people’s political views. He’s an assistant professor of politics and public affairs at Princeton University. Last summer, he was part of a big team that released four papers on their analyses and experiments in social media all at the same time. The research was in collaboration with Meta, the company responsible for Facebook and Instagram. 

Andy and the team were able to dissect how often people on these platforms are exposed to political opinions, particularly from people whose opinions differ from their own. They were also able to conduct experiments on these platforms. By turning some of the knobs and levers, could they influence people’s engagement on these platforms and even change their political views?

The four big research papers that all came out together are:

• Guess et al. (2023, Science): How do social media feed algorithms affect attitudes and behavior in an election campaign?
• Guess et al. (2023, Science): Reshares on social media amplify political news but do not detectably affect beliefs or opinions
• Gonzalez-Bailon et al. (2023, Science): Asymmetric ideological segregation in exposure to political news on Facebook
• Nyhan et al. (2023, Nature): Like-minded sources on Facebook are prevalent but not polarizing

Sendhil Mullainathan does a lot of things, and he does them well. He’s a professor of Computation and Behavioral Science at the University of Chicago’s Booth School of Business. I originally talked to Sendhil for our podcast series, They Thought We Were Ridiculous. He was well-positioned to give his perspective on a contentious, interdisciplinary field of social science called “behavioral economics.” But nowadays, behavioral economics is mainstream, but Sendhil has continued to study big questions that cut across the typical academic boundaries between disciplines. We talk about AI, economics, and racial bias.

You can listen to our full series on behavioral economics here (Sendhil’s voice pops up in episodes 3 and 4).

Also, the study we discuss testing racial discrimination in hiring practices was first reported in this 2003 paper in American Economic Review.

To look into the future of Behavioral Economics, we talked to three young researchers who are pushing the field further. A new generation of researchers is striving to understand decision-making in the developing world, how brains process economic decisions, and how bigger, more transparent scientific methods can shed light on basic principles of choice. 

This is the fifth episode of a special series called: "They Thought We Were Ridiculous: The Unlikely Story of Behavioral Economics."

*Correction:  During Rahul Bhui's section of the episode, we mistakenly said that people "don't take as many risks when they're framed as potential losses…even though they're relatively happy to take risks when they're framed as potential gains." We accidentally got this flipped! In truth, research on prospect theory shows that people tend to be risk-seeking in the loss domain but risk-averse in the gain domain.

Behavioral Economics was using psychology to understand economics, but what did economists and psychologists think about their unexpected marriage? Slowly, this fledgling field weathered a flurry of criticism from both sides as it doggedly held onto data-driven ideas about economic decision-making. 

This is the third episode of a special series called: "They Thought We Were Ridiculous: The Unlikely Story of Behavioral Economics."

Daniel Kahneman and Amos Tversky were two psychologists with big ideas about how people made decisions. Their careful research launched a brand new way of understanding people’s choices, and it helped fan the flames of Behavioral Economics.

This is the second episode of a special series called: "They Thought We Were Ridiculous: The Unlikely Story of Behavioral Economics."

For years, neoclassical economists have made an unusual assumption—that people are rational decision-makers. But a few social scientists have dared to challenge that assumption. They’ve collected observations, analyzed data, and presented their perspective. Their work would usher in a new era of Economics. 

This is the first episode of a special series called: "They Thought We Were Ridiculous: The Unlikely Story of Behavioral Economics."

Jack Dovidio's work is at the heart of how we currently understand the psychology of prejudice. He's spent his career considering where prejudice comes from, how people express it, how it biases people's judgments and behaviors, and what we could do to address it. He's an emeritus professor at Yale University, and he's also just a really pleasant guy to talk to. In our conversation, we cover his early days as a social psychologist studying when people will help each other out, his research on "aversive racism," and his work studying the effects of racial bias in medical treatment.

The new book out by Jack, Lou Penner, and others is: "Unequal Health: Anti-Black Racism and the Threat to America's Health"

Things that come up in the intro:

• Gordon Allport’s “The Nature of Prejudice”
• Polling over time on interracial marriage (Gallup) and racial progress (Pew)
• Economists sell baseball cards on eBay to learn about racism (Ayres et al., 2015)
• A retrospective on The Nature of Prejudice (Dovidio et al., 2005)

Jim McNulty is a professor of psychology at Florida State University. He studies close relationships, and in this episode, we talk about his research on "automatic partner attitudes." When someone sees their romantic partner, their feelings about that person spring automatically to mind. And sometimes those feelings conflict with what they openly SAY they feel about their partner. Jim shares his findings from studies that measure people's feelings toward their partners.

Things that come up in this episode

• A longitudinal study of newlyweds shows how automatic attitudes are related to relationship outcomes years later (McNulty et al., 2013)
• Automatic evaluations of one's partner are related to relationship satisfaction (Turner & McNulty, 2020)
• Interventions that improve people's evaluations of their partners improve relationships outcomes (McNulty et al., 2017)
• A recent paper summarizing Jim's work on automatic evaluations of one's partner (Faure et al., 2024)

Happy New Year! For the first time in the show's history, this episode's a day late. Sorry, dear listeners.

So it's 2024, and what better way to kick off the new year than to dive into some nostalgia for 2023 already? As has become tradition around here, I compiled some clips of favorite moments on the podcast from the last year. As I say every year, it’s not truly a “best of” per se because I really am attached to every episode. Instead, I’ve chosen some clips that highlight the kind of show this is, including some of the things that made this year especially special.

If you’re new to the show, this is a great place to start! And if you’ve been listening since the beginning, join me on some fun memories from this year.

-Andy

Elizabeth Dunn studies the psychology of happiness. One of her major research areas has looked at generosity's effects on well-being. We're happier when we spend money on other people. But studying happiness has its challenges, especially if we want to build strategies that help people feel happier. So, she shared a snapshot of her research on happiness and a new paper with Dunigan Folk looking at how strong the evidence is for different happiness-boosting strategies.

Things that come up in this episode: 

• A big social experiment through the TED organization to see what people do when they receive $10,000 (Dwyer & Dunn, 2022; Dwyer et al., 2023)
• The benefits of generosity for our well-being (see Dunn et al., 2020; also see Episode 23 with Lara Aknin)
• Digging deep into the research on happiness to see how strong the evidence is for happiness-boosting strategies (Folk & Dunn, 2023; also Folk & Dunn, 2024)
