Two Psychologists Four Beers

Andy Masley joins Yoel and Mickey to talk about a claim that's made him (in)famous: using AI chatbots doesn't meaningfully affect your carbon footprint or water usage. We discuss what data centers actually do with water, why "ten times a Google search" is not a useful metric, and why people really don't want data centers built near them. We also talk about Andy's involvement in effective altruism, which criticisms of it he takes seriously, and whether a grant from an EA funder should make you trust him less. Plus, some self-driving car discourse, and Yoel tries to drink a bottle of bourbon. Finally, a small correction from Andy: "I misspoke at 48:00 and said you'd need to send 150,000 prompts to raise your emissions by 1%, I got my wires crossed with how much you'd need to double your emissions and the actual number should be 1,500 per day." Special Guest: Andy Masley.

Paul and Yoel talk about whether it's a problem that psychologists seem to be no better than laypeople at predicting behavior. We also cover a recent controversy in anthropology, talk a little bit about the Odyssey (movie), and discuss whether people ought to be drinking more. (Sorry about the clicking in Paul's audio--we did what we could to tone it down!) Special Guest: Paul Bloom.

Cognitive scientist Molly Crockett joins the show to talk about what it's like to be known in the field as an "AI skeptic." We talk about where Molly is actually skeptical, but also what she thinks that label gets wrong. Along the way, we cover a bunch of other things too: Molly's research in social neuroscience, computational modeling, and moral psychology; Molly and Mickey's disagreements about empathic AI; and Molly's case for what she's calling "thick empathy." Finally, Molly makes a pitch for non-alcoholic beer, which sadly falls on deaf ears. Special Guest: Molly Crockett.

Researcher, professor, and former Division III football player Nick Epley joins the show to talk about why we underestimate the benefits of social connections. We are a social species, and yet many of us choose to avoid connecting with others. Nick and I talk about his research on this, and about his new book, A Little More Social , which is all about how we can change our behavior to connect more with others. Special Guest: Nick Epley.

Instead of a new episode this month, we have one from the vaults that many newer listeners might not have heard (because it came out almost 7 years ago). But, especially since Paul has a new baby (see first link), re-releasing this one seemed fitting. And it's always been one of my favorites. We'll be back with new episodes in the coming months. Original Episode Description Yoel and Mickey welcome Paul Bloom to the podcast, who is not only a returning guest but also the Brooks and Suzanne Ragen Professor of Psychology at Yale University. We first give terrible advice on parenting. Does parenting affect happiness, relationship satisfaction, and meaning? Does parenting screw with prospective decision making because it leaves the decision maker utterly transformed? We next discuss perversity. Why do we enjoy doing transgressive things? Who is likely to be perverted? Is perversion ever a good strategy? Bonus: How would Paul rate Yoel on a scale of 1 to 5? Special Guest: Paul Bloom.

Many academics care about diversity in faculty hiring, but why? Azim Shariff joins the show to talk about his new paper where he describes rationales for diversity in hiring, and an as-yet unpublished study where he asked department chairs how much they actually care about those rationales. We also talk about the empirical evidence for the diversity rationales (it's mixed!), Paul Bloom's argument against viewpoint diversity, and the future of DEI policies in the U.S. Plus, Azim deviates from his long-standing practice of not drinking beer. Special Guest: Azim Shariff.

Mickey and Yoel talk about Canada's controversial euthanasia law (called MAID: medical assistance in dying). Since its introduction in 2016, an increasing number of Canadians are choosing euthanasia (in recent years, more than 5% of deaths in Canada were the result of MAID). We talk about the history of the law, criticism of it in Canada and abroad, and our own discomfort (or lack of) with legal euthanasia. Separately, we also discuss a new paper that claims to show robust ego depletion effects--but is it just showing fatigue by another name?

Paul Litvak joins the show to talk about how AI tools can help us measure research quality and assess evidence in the scientific literature. His first project is a way to extract test statistics and p-values from papers automatically, with no manual coding needed. We also talk about Paul's non-profit dedicated to improving the reliability of scientific research, the legendary judgment and decision making scholar Robin Dawes (whose entirely algorithmic approach to graduate student selection once went terribly awry), and Paul's exit from academia. Plus, Yoel reveals a shameful secret about his use of AI. Special Guest: Paul Litvak.

Mickey is back and fired up about citation diversity statements. We talk about a recent editorial from Nature Reviews Psychology encouraging authors to include a "citation diversity statement" in their articles to "to draw attention to citation imbalances and confirm that they made efforts to cite publications from a diverse group of researchers." We discuss what we don't like about the editorial, as well as the strongest case for it. We also talk about SpringerNature's profit margins, posting on LinkedIn, and Mickey's extremely problematic beer views.

David Tannenbaum (Associate Professor of Management at the University of Utah) joins the show to talk about one of Yoel's favorite papers: a massive field study of honesty in 40 countries that had some unexpected results. We talk about the promises and pitfalls of field studies, what happens when your results are not at all as expected, and how to deal with going viral (in a bad way). Also, we talk about our recent hiking trip and David actually drinks two beers. Special Guest: David Tannenbaum.

This is a re-release of Episode 95, which was recorded in September 2023. Paul Bloom joins Yoel and Alexa to talk about the glamour and humiliation of teaching psychology at the college level. They discuss how they've changed their approaches to teaching over the years, and whether they've become more skilled or more out of touch (or both). Alexa shares her experiences teaching about morality and evolution to a predominantly Christian student body, Yoel laments the fact that his students aren't more disagreeable, and Paul claims that critical thinking is overrated. In an era of increasing remote instruction, they claim that online courses can't do what they do. But, only Yik Yak knows for sure. Special Guest: Paul Bloom.

Paul Bloom takes over the show to interview Yoel about loss of faith: when to give up on a theory, and which of his own findings he no longer believes. But it's not all doom and gloom! They also talk about what social psychology findings they think are robust, and what new research they are excited about. But before all that, they discuss whether Sydney Sweeney's new American Eagle ad campaign is pro-eugenics. Special Guest: Paul Bloom.

Yoel is joined by a mysterious pseudonymous duo called Slime Mold Time Mold, who are proposing a new paradigm for psychology based on principles from cybernetics. This means thinking of the behavior as the result of "governors" (think drives) that are trying to reduce the distance between a set point and the state of the world by motivating you to do stuff. So when you are thirsty, you are highly motivated to drink, and when you need to pee, you are highly motivated to find a toilet. Those are simple examples, but can we use the same principles to explain more complex phenomena like emotion, motivation, personality, mental illness, and more? That is what my guests on this episode are proposing. Special Guest: Slime Mold Time Mold.

Returning guest Spencer Greenberg joins the show to talk replications, what psychologist think of terror management theory (and other controversial topics), and a machine-learning tool he developed to predict correlations between psychological traits and survey questions. In this episode, we talk about what Spencer has learned by replicating studies from recent publications in psychology, the decline of p-hacking, and what other threats to validity psychologists should be worried about. Special Guest: Spencer Greenberg.

It's been a tumultuous time for DEI (diversity, equity, and inclusion) efforts in higher education. Whether due to political pressure, internal arguments, or both, many prominent institutions are revamping their DEI offices (or even eliminating them altogether) and rethinking DEI policies that once seemed unquestionable. Amori Mikami from the University of British Columbia re-joins the show to talk about the changes and what she thinks universities ought to be doing (as well as what she thinks we can do better). Along the way, Yoel and Amori talk about the use of race and gender in hiring, diversity statements, October 7 and the Gaza war, and institutional neutrality (in short, this episode touches every third rail imaginable). There's some debate and some agreement, but most importantly we both finish our beers. Special Guest: Amori Mikami.

Arguably, the last 25 years of moral psychology have been about people's judgments of "purity violations"--ostensibly harmless acts that "are disgusting or degrading to one’s spiritual nature." From sex with (dead) chickens to pet-eating to baby Jesus buttplugs, moral psychologists have been fascinated by purity transgressions. Moral psychologist and purity expert David Pizarro joins the show to talk about the concept of purity and recent critiques arguing that it's a concept too broad to be useful. Along the way, we also discuss how often to shower, getting into bed in your outside clothes, and ritualistically washing your dad's feet. Special Guest: David Pizarro.

On-again off-again co-host Mickey Inzlicht joins the show to debrief about the recent SPSP (Society for Personality and Social Psychology) conference. We then dissect a new paper purporting to show working memory deficits in heavy cannabis users, including a deep dive into the preregistration. Finally, we discuss a recent Op-Ed in the Guardian that argues that research on AI empathy is fatally flawed.

Cultural and developmental psychologist and open science advocate Moin Syed joins the show to talk what he thinks people get wrong about ideology, diversity, and open science. We talk about what role, if any, researchers' ideology should play in their science, and what it means when people describe psychological research as "ideological." In the second half of the show, we talk about what people get wrong about preregistration, and why it seems some misconceptions just won't die. We also talk about Moin's attempt to correct some misinformation (it did not go that well), and some local beer history. Special Guest: Moin Syed.

Occasional co-host Mickey Inzlicht joins the show to talk about the 2024 election, Bluesky, and his crusade against yard signs. We discuss prediction markets, Democratic declines with non-college voters, and whether Bluesky is a political bubble (and if so, if there's anything wrong with that). Also, Mickey explains his problem with yard signs and defends his beer snobbery.

Paul Bloom joins the show to talk about a recent paper in which he argues that much of developmental psychology is not worth doing. We also talk about where he thinks psychology has succeeded, and whether we should be more skeptical of progressive-friendly social science findings. Plus: is it ever a good idea to tell your friend that the person they're dating is bad for them? Special Guest: Paul Bloom.
