Melissa Kearney discusses the long-term benefits of growing up in a two-parent household, the decline in marriage rates in the United States, the impact of non-marriage on children and society, policy proposals for reversing the declining marriage trend, and the cultural war among social scientists regarding the significance of the family.

While it seems intuitively obvious that good management is important to the success of an organization, perhaps that obvious point needs some evidence given how so many institutions seem to muddle through regardless. Enter Raffaela Sadun, the Charles E. Wilson Professor of Business Administration at Harvard Business School and co-leader of the Digital Reskilling Lab there. Working through several managerial mega-projects she co-founded, Sadun can both identify traits of successful management and even put a quantitative value to what good management can bring to a firm (spoiler alert – as Sadun will explain, it’s a big number). In this Social Science Bites podcast, Sadun discusses her research findings with host David Edmonds, who open his inquiry with a very basic question: What, exactly, do we mean by ‘management’? “It's a complicated answer,” Sadun replies. “I think that management is the consistent application of processes that relate to both the operations of the organization as well as the management of human resources. And at the end of the day, management is not that difficult. It’s being able to implement these processes and update them and sort of adapt them to the context of the organization.” In a practical sense, that involves things like monitoring workers, solving problems and coordinating disparate activities, activities that ultimately require someone “to be in charge.” But not just anyone, Sadun details, and not just someone who happens to be higher up. “The most effective managers are the ones that are able to empower and get information and reliable information from their team, which is fundamentally a bottom-up approach rather than a top-down approach.” If that sounds a little different from the adversarial relationship many expect between workers and managers, well, good management is a little different, she continues. “I can see how you can think of this as being a trade-off (profit versus well-being of workers), but if you look at the type of practices that we measure, as I said, they're not exploitations, but they are ways to get people engaged and empowered to sort of participate into the work. It’s always possible that there are organizations that push so much on one side of the equation that make people very unhappy. In my experience, these type of situations are not sustainable.” Good people – the ones employers prize -- won’t put up with too much garbage. “Talented people are attracted--to the extent that they want to work for somebody else—they're attracted to places where their life is not miserable.” Sadun came to her conclusions through projects like the World Management Survey, which she co-founded two decades ago. “We spoke with more than 20,000 managers to date—around 35 countries, [and ..] collected typically [by] talking with middle managers.” Other big projects include the Executive Time Use Study, and MOPS-H, the first large-scale management survey in hospitals and one conducted in partnership with the US Census Bureau.  In her native Italy, Sadun was an economic adviser to the Italian government in the early 2020s, earning the highest honor possible from the government, the Grande Ufficiale dell'Ordine "Al Merito della Repubblica Italiana." In the United States, serves as director of the National Bureau of Economic Research Working Group in Organizational Economics, and is faculty co-chair of the Harvard Project on the Workforce.

“We have been evolving into a species that is super-cooperative: we work together with strangers, we can empathize with people, we are really an empathic flock,” begins Carsten de Dreu, a professor at Leiden University. “And at the same time, there is increasing evidence from archaeological excavations all around the world that already 10, 20 and 30 thousand years ago, people were actually violently killing each other.” Trained as a social psychologist, de Dreu uses behavioral science, history, economics, archaeology, primatology and biology, among other disciplines to study the basis of conflict and cooperation among humans. In this Social Science Bites podcast, he discusses how conflict and violence – which he takes pains to note are not the same – mark our shared humanity and offers some suggestions on how our species might tamp down the violence. “Violence,” de Dreu explains to host David Edmonds, “is not the same as conflict – you can’t have violence without conflict, but you can have conflict without violence.” Conflict, he continues, is a situation, while violence is a behavior. Conflict, he says, likely always will be with us, but resorting to violence need not be. The psychologist says behavior has a biological basis, and various hormones may ‘support’ violent actions. For example, greater concentrations of oxytocin – which helps maintain in-group bonds and has been dubbed “the love hormone” -- is found in primate poo after groups fights. But, he cautions, that is not to say we are innately violent. But when we do get violent, it’s worse when we’re in groups. Then, the potential for violence, as he put it, “to get out of hand,” increases, escalating faster and well beyond the violence seen between individuals (even if that one-on-one violence sometimes can be horrific). “In an interpersonal fight, the only trigger is the antagonist. In intergroup violence, what we see is that people are sometimes blinded to the enemy – they might not even recognize who they were because they were so concerned with each other.” What drives this violence is both obvious and not, de Dreu suggests. “Even among my colleagues, there is sometimes fierce debate - conflicts sometimes about what are conflicts! But if you zoom out, there are two core things that groups fight about:” resources and ideas. Fighting over resources is not unique to humans – groups of primates are known to battle over land or mates. But fighting over ideas is uniquely human. And unlike resource conflicts, which have the potential to be negotiated, “for these truth conflicts ... there is no middle ground, no trade-off.” Regardless, he argues, values have value. Citing recent work with colleagues, de Dreu says he thinks “these values, these truths, these worldviews that we have, that we share within our groups and our communities, within our countries sometimes, they are the ‘oil’ of the system. To work together so that we all can survive and prosper, we need certain rules, a certain shared view of how the world operates, what is good and bad, what is right and wrong. These are very important shared values we need to have in order to function as a complex social system.” But “when these values get questioned, or attacked, or debunked, that’s threatening.” Depending on how severe the threat is seen, violence is deployed. And sometimes, as even a casual observer may divine, it’s not the direct quest for resources or to protect values that sparks violence, but what de Dreu terms “collateral damage” from leaders cynically weaponizing these drivers – or even inventing threats to them -- while actually pursuing their own goals. But de Dreu ends the podcast on a (mostly) upbeat note. He says we can break the cycles of violence, even if there’s no neat linear trajectory to do so, and concludes by offering some rays of hope.

In the Global North, media and political depictions of migration tend to be relentless images of little boats crossing bodies of water or crowds of people stacking up at a dotted line on a map. These depictions presume two things – that this is a generally comprehensive picture of migration and that, regardless of where you stand, the situation around migration is relatively dire. Enter Heaven Crawley, who heads equitable development and migration at United Nations University Centre for Policy Research. She also holds a chair in international migration at Coventry University’s Centre for Trust, Peace and Social Relations, and directs the South-South Migration, Inequality and Development Hub since 2019, a project supported by UK Research and Innovation’s Global Challenges Research Fund. From her perch, spanning government, academe and field research, she says confidently in this Social Science Bites podcast that international migration “is not an entirely positive story, but neither is it an entirely negative one. What we’re lacking in the media conversation and in the political discussion is any nuance.” Connecting nearly all the regional debates about migration “is the lack of an honest conversation about what migration is and what it has been historically. It has historically been the very thing that has developed the societies in which we live, and it is something on which the clock cannot be turned back. “And none of us, frankly, if migration was to end tomorrow, would benefit from that.” Trying to bring a clear eye to the debate, she explains to host David Edmonds that roughly 3.6 percent of the world’s population, or 280 million people, could be considered migrants. Of that, about 32 million fit under the rubric of “refugee.” And while the sheer number of Migrants is growing, the percentage of the world’s population involved has been “more or less the same” last three decades.   And while this might surprise European listeners, almost 40 percent of migration originates from Asia-- mostly India, Pakistan and Bangladesh -- followed by Mexico. There is a lot of migration from African countries, Crawley notes, which gibes with European media, but most of that migration isn’t to Europe, but within the African continent. Who are these migrants? Overall, she says, most people who move are less than 45. Nonetheless, “the gender, the age really depends on the category you’re looking at and also the region you are looking at.” Generalizations about their qualifications can be fraught: low-skills migrants ready to fill so-called “dirty, difficult and dangerous jobs” and high-skill migrants draining out their country’s brains can often depart from the same nation. Crawley agrees that migration currently is a politically potent wedge issue, but she notes it has been in the past, too. She suggests that migration per se isn’t even the issue in many migration debates. “A whole set of other things are going on in the world that people find very anxiety-producing” – rapid changes in society drawing from security, economy, demographics, and more, all against a backdrop of “migration simultaneously increasing (in the number of people on the move, not the proportion) and the variety of people also increasing.” This creates an easy out for policymakers, she says. “Politicians know that if they’ve got problems going on in society, it’s very easy to blame migration, to blame migrants. It really is a very good distraction from lots of other problems they really don’t want to deal with.” This is also why, she suggests, that responses such as deterrence are more popular than more successful interventions like addressing the inequalities that drive migration in the first place. Crawley’s career saw her sit as head of asylum and migration research at the UK Home Office, serve three separate times as a specialist adviser to the UK Parliament’s Home Affairs Committee and Joint Committee on Human Rights, and be associate director at the Institute for Public Policy Research. In 2012, in recognition of her contribution to the social sciences and to evidence-based policymaking, she was named a fellow of Britain’s Academy of Social Sciences.

Everyone, it is said, is allowed their own opinion. But what if someone’s own opinion was in fact one foisted on them by someone else, and yet the original opinion holder in turn holds the changeling opinion as their own? Unlikely? Actually, not so unlikely, as the research of Petter Johansson and Lars Hall into ‘choice blindness’ shows. In this Social Science Bites podcast, Johansson – who with Hall runs the Choice Blindness Laboratory at Sweden’s Lund University – reveals some of the unexpected aspects of self-interpretation and how there’s been a very large natural example in the United States of this blindness in action. We are “less aware of the reasons for our choices than we think we are,” he has determined, and reasoning, as we call it, is often conducted post hoc. Johansson starts his discussion with host David Edmonds by giving his and Hall’s first forays into the study of “how we come to know our own minds.” Their work built on others’ research into something called “change blindness,” which describes not noticing a change – even a major one – that occurs before your eyes. (Inattentional bias – such as the famous gorilla basketball video – is when we miss something obvious but unexpected right before us because we’re focusing on something else in the tableau. “I’ve seen this at conferences on monster-sized screens, when it is practically King Kong walking in the background, but still people miss this.”) Johansson describes how the research partners ‘magically’ morphed this line of inquiry into studies of what they call “choice blindness” using a card trick. “When you have the appearance of free choice,” he says, “when you have the magician say, ‘Pick a card, any card you want,’ the only thing you know is that the choice is no longer free. This was the aspect we wanted to incorporate into our experiments.” In the initial experiment, subjects were shown pairs of faces on cards, and asked to choose which they found more attractive. The researcher then handed them that card and asked why they chose it over the other. But sometimes, using sleight of hand, the researcher handed the subject the card with the other face, and asked again why they chose that face. “Even when the faces were drastically dissimilar, and the [subjects] could look at the cards for as long as they want, only 25 to 30 percent of the participants detect that the switch has been made,” Johansson reveals. “But it’s not only that they pick it up – they then must start constructing reasons why they picked this face,” justifying a choice they didn’t make. Subsequent experimentation found that opinions on taste, smell, consumer choice, and more could be subject to such blindness. The researchers, for example, set up a tasting station at a local supermarket, and after having the ol’ switcheroo played on their choice of jam, the subjects came up with “similar types of elaborate explanations” for why the jam they didn’t choose was in fact the better one. The researchers also worked with pairs of people, asking them who they might choose to flat with. And here the resulting confabulation was collective. The researchers also found choice blindness in politics (especially when the other opinion had a reasonable case that could be made). People on the street were asked to participate in survey about a policy position, and the interviewer would respond with “you clearly believe …” in a position they didn’t choose. And as you now will expect, the subjects defended their ‘new’ stance. “This says something about what a belief is, or an attitude is,” Johansson says. The source of the opinion matters: if you think it comes from you – even when it in fact did not – there must be good reason to hold the opinion. “People don’t like being told what’s right or wrong. But if you can tell yourself what’s right or wrong, it’s much more likely to stick.” And this can also be outsourced when your “team” makes a call, and partisans “quickly change their own attitudes to match.” Which brings us to former U.S. President Donald Trump. Under Trump, Johansson says, “It felt like there was four years of showing this point almost every day. Trump would change the policies or long-held beliefs almost every day and Fox and Friends and all these voters would just fall in line and quickly construct arguments why this was the right view all along.” While this might seem a dour outcome with opinion chameleons calling the shots, Johansson sees a brightside. “It does show we are probably more flexible than we think. We have the ability to change.”

“Ah, but a man’s reach should exceed his grasp,” the poet Robert Browning once opined, “or what’s a heaven for?” That’s not a very satisfying maxim for someone trying to lose weight, learn a language, or improve themselves in general on this earthly plane. But there are ways to maximize one’s grasping ability, and that’s an area where psychologist Ayelet Fishbach can help. Fishbach, the Jeffrey Breakenridge Keller Professor of Behavioral Science and Marketing at the University of Chicago Booth School of Business, studies goals and motivations. It's work that saw her serve as president of the Society for the Science of Motivation and the International Social Cognition Network and to pen the 2022 book, Get it Done: Surprising Lessons from the Science of Motivation. In this Social Science Bites podcast, she tells interviewer David Edmonds that one tip for setting goals is to make them concrete. So, for example, resolving to ‘being a good husband’ works, but ‘being happy’ does not. ‘Being happy’ is just too abstract. “You need to get to the level of abstractness that is motivating … but not too abstract that it is no longer connected to an action,” Fishbach explains, adding that there must be “a clear connection between the goal and the means.” However, she continues, research suggests that people -- while focused on the ends -- tend to scrimp on the means. Fishbach notes research on MBA students found they were willing to pay $23 for a particular book – but only willing to pay $11 for a tote bag that they knew also contained the book. The value of the bag, which was negligible but still extra step to getting the book, was therefore negative. “Which makes no sense,” she acknowledges, “but it illustrates the point.” Goals, she says, should be things we can “do,” what we can achieve, as opposed to prohibitions on actions, those “do nots” that describe what we should avoid. “Do” prompts, she continues, “are more intrinsically motivating. You are more excited about them. It feels good and right.” Plus, focusing on what we’re avoiding puts that thing in front of mind – which makes it harder to ignore. Fishbach calls for measuring your “do” activities, setting targets. She cites a study that saw marathon running times in the United States were not being evenly distributed, but clumped around just-before milestone times like three-and-a-half or four hours, suggesting runners pushed themselves to hit their personal targets. And where there are targets, there can be rewards. “Rewards work better than punishments,” she says, “but they don’t always work in the way they were intended to work.” If we incentivize the wrong things, behavior bends toward the incentive rather than the underlying goal. Oddly enough, “uncertain incentives seem to work better than known ones." Fishbach was part of a research team that saw people would work harder for a $1 or $2 prize, with the amount determined by a coin flip, than they were for a $2 guaranteed prize. “The excitement of resolving uncertainty is always better than the reward you are getting.” Other topics Fishbach addresses in this episode include internal motivations (immediate returns trumped longer-term rewards), how to sustain motivation, and whether we truly learn more from failure than success.

In this Social Science Bites podcast, interviewer David Edmonds asks psychologist Kathryn Paige Harden what she could divine about his educational achievements if all she knew about him was his complete genome. “Based just on your genetic information,” she starts, “I would be able to guess about as well as I would be able to guess if I knew how much money your parents had made per year when you were growing up.” Based on current knowledge drawn from recent samples in the United States, Harden estimates an “educational attainment polygenetic score” accounts for 15 to 17 percent of the variance in educational attainment, which is defined by years of formal education. The strength of the relationship is similar to environmental factors such as that for family wealth and educational attainment, or between educational attainment and wages. Harden’s “guess” is as about as educated as someone in the realm could make – she directs the Developmental Behavior Genetics Lab and co-directs the Texas Twin Project at the University of Texas. Her first book was 2021’s The Genetic Lottery: Why DNA Matters for Social Equality. One thing she stresses is that genetic influence on human behavior is not the single-factor ideal youngsters learn about in their first brush with Gregor Mendel and his pea plants. “Almost nothing we study as psychologists is monogenetic, influenced by one gene. It’s all polygenetic, meaning that there are thousands of genetic variants, each of which has a tiny probabilistic effect. If you add up all of that information, all of that genetic difference, it ends up making a difference for people’s likelihood of developing schizophrenia or doing better on intelligence test scores or having an autism spectrum disorder – but none of these things are influenced by just one gene.” Plus, that “polygenetic score” varies based on environmental factors, such as whether you were raised in an authoritarian state. “If I had my exact DNA that I have now,” she details, “but I was raised in 1850s France compared to 1980s America, my educational output would be different, obviously, because my gender would have been interacting with those opportunity structures in a different way.” As those structures evolve into ladders instead of roadblocks, the more utility we can derive from knowing the role of genetics. “The more we ‘level the playing field,’ the more that people have environments that are rich and conducive to their individual flourishing, the more we should expect to see, and the more in empirical practice we do see, the role of genetic differences in people.” In the shadow of eugenics and other genetics-based pseudo-sciences legacy, is harnessing that genetic influence for policy use good or bad? As Harden has experienced since her book published, “you can’t really talk about genes and education without fairly quickly running into some contested issues about fairness and equality.” In fact, she argues that much of her on heritability doesn’t so much answer social science questions as much as it “poses a problem for the social sciences.” In the podcast Harden discusses the Genome-wide Association Study, which she describes with a laugh as “a giant fishing expedition” in which researchers measure the DNA – genotype – from thousands or even millions of individuals and then measure that across the genome, for what comes down to “ a giant correlational exercise. Which genes are more common in people who are high on a trait versus low on a trait, or who have a disease versus don’t have a disease?” Harden also addresses the reasons she studies identical twins in her research, the cooption of genetic tropes to advance toxic worldviews, and how race – which she rejects as a proxy for genetic differences — plays out in the real world as opposed to the lab.

In the most innocent interpretation, suggesting someone should ‘do their own research’ is a reasonable bit of advice. But in the superheated world of social media discourse, #DoYourOwnResearch is a spicy rejoinder that essentially challenges someone to Google the subject since they clearly don’t know what they’re talking about. But Googling, social psychologist David Dunning pointedly notes, is not research. “The beauty and the terror of the internet,” he tells interviewer David Edmonds in this Social Science Bites podcast, “is that there’s a lot of terrific information, but there’s also a lot of misinformation and sometimes outright fraud. “People often don’t have the wherewithal to distinguish.” This distinguishing is an area where Dunning, a professor at the University of Michigan, does his own research. While doing your own internet sleuthing isn’t toxic on its face, Dunning suggests that often “you don’t know when you’re researching your way into a false conclusion, and … you don’t know when to stop. The real hard problem with DYOR is when do you know when to stop: you go and you look at a couple of web pages, and ‘Well, you’ve learned something! Terrific!’ But you don’t know how much there is behind it that you still need to learn.” One driver of DYOR, Dunning adds, is the idea that gaining (and deploying) knowledge is one’s own responsibility, which pretty much runs counter to science, which sees gaining knowledge as a collective enterprise. One piece of collective effort in which Dunning has made a very public mark is in describing what’s come to be known as the Dunning-Kruger effect, named for Dunning and fellow social psychologist Justin Kruger of New York University, after work they originally described two decades ago in “Unskilled and unaware of it: How difficulties in recognizing one's own incompetence lead to inflated self-assessments” in the Journal of Personality and Social Psychology. The popular definition of the Dunning-Kruger effect, Dunning explains, is that “people who are incompetent or unskilled or not expert in a field lack expertise to recognize that they lack expertise. So they come to conclusions, decisions, opinions that they think are just fine when they’re, well, wrong.” Dunning and Kruger’s initial research was based on simple tests – of grammar, logical thinking, classical psychology quizzes, even sense of humor – asking subjects how well they think they’re doing relative to everyone else. They found that the bottom 25 percent of participants tended to think they were doing above average. “But no.” “To know what you don’t know,” he offers, “you need to know what you need to know to realize that your thinking diverges from that.” It’s not true in every endeavor, he adds. “I’m a terrible golfer,” Dunning says. “And I’m fully aware that I‘m a terrible golfer!” The effect tends to show up when the skill of assessing outcomes is roughly similar to the skill of achieving outcomes. So when your golf ball flies into the nearby body of water, you don’t need special skills to know that’s bad. Becoming an expert in everything is out of the question; the real skill will be in identifying who is a legitimate expert and drawing on their insights. (And the right expert, Dunning notes “is the right experts. With an S on the end.”) For the record, the pair – who just received the 2023 Grawemeyer Award in Psychology for their Dunning-Kruger effect work - did not name the concept after themselves, although, as Dunning says, they’re “tickled pink that our names will forever be associated with the nincompoops, incompetent ignorant cranks, if you will.”

Historically and into the present day, female workers overall make less than men. Looking at college-educated women in the United States, Harvard University economic historian Claudia Goldin studies the origins, causes and persistence of that gap, which she discusses in this Social Science Bites podcast. Goldin, whose most recent book is Career & Family: Women's Century-Long Journey toward Equity, details for host David Edmonds how the figures she uses are determined. Specifically, it’s the ratio of female-to-male weekly earnings for those working full-time and year-round, with the median woman compared to the median man. “Expressed in this way, there has been real progress” in the last century, she says. Today in the United States, where Goldin’s studies occur, that number is below 85 cents on the dollar. While that trend is good news, it’s not the whole story. “By expressing this gap in this single number we miss the really, really important dynamics, and that is that the gender earnings pay gap widens a lot with age and it widens a lot with [having] children, and it widens in the corporate, banking and finance, and law sectors.” And while the gap may have narrowed, it shows no evidence it’s about to close. Acknowledging the “persistent frustration” about the pay gap’s durability, Goldin pointed a finger at structural inequities, bias and sexual harassment, but she also argues that “greedy work” was a major factor. Greedy work “is a job that pays a disproportionately more on a per hour basis when someone works a greater number of hours or has less control over those hours.” Hence, the gap persists “not so much [because] men and women go into completely different occupations,” she explains, but that women are financially “penalized” for choosing work that allows flexibility within that occupation. “The important point,” she adds, “is that both lose. Men are able to have the family and step up because women step back in terms of their jobs, but both are deprived. Men forgo time with their family and women often forgo their career.” But losers can win – eventually. The more that workers say to their supervisors that “we want our own time” the more the labor market will change, she explains by pointing to current trends. One caveat, though, is that the situation is worse among women without college educations. Goldin is the Henry Lee Professor of Economics at Harvard University and was the director of the National Bureau of Economic Research’s Development of the American Economy program from 1989 to 2017. She is a co-director of the NBER's Gender in the Economy group. She was president of the American Economic Association in 2013 and was president of the Economic History Association in 1999/2000. She is a member of the National Academy of Sciences and the American Philosophical Society and a fellow of the American Academy of Political and Social Science, the American Academy of Arts and Sciences, the Society of Labor Economists (which awarded her its Mincer Prize for life-time contributions in 2009), the Econometric Society, and the Cliometric Society. She received the IZA Prize in Labor Economics in 2016, the 2019 BBVA Frontiers in Knowledge award, and the 2020 Nemmers award, the latter two both in economics.
