A new people has emerged in the digital age, that of 'internet famous' celebrities. And that new people has a class of social scientist focused on studying them, the digital anthropologist. Crystal Abidin, a professor at Australia's Curtin University and founding director of the Influencer Ethnography Research Lab there, is such as digital anthropologist. Her research covers influencers – both adult and child and the general pop culture centered on social media, especially in the Asia Pacific region.

In this Social Science Bites podcast, Abidin offers interviewer David Edmonds a metaphor to understand how her cyber-ethnography and digital anthropology work in practice. "I often think of anthropologists as Mars rovers that you throw into these unknown planets, and slowly but surely, we roll around the planet looking for bits of data, bits of material that might be new or novel. We're not going for quantity and volume at this scale. We're looking for what's neglected, unseen, sidelined by the margins, not yet mainstream. And we're measuring how much of these things are characteristic of the planet and worthy of study. … [A]s an anthropologist, given that my fidelity is to people and their cultures, I don't always only go for the shiniest, most mainstream thing. I often look for what's left behind."

In this conversation, though, Abidin talks about something very shiny indeed – those professional internet celebrities known collectively as "influencers." She explains how while the top influencers do generate the paydays seen in popular media, the ecosystem extends down to individuals who are spending their own money in hopes of someday making it big. She also draws a distinction between influencers and creators, and also between influencers and memes.

Abidin also dives into regional differences in influencer culture, using her own detailed analysis of Asia Pacific influencer cultures, to explore regional differences that should be understood when assessing content on global platforms. "[I]f we were to discount the hegemony of American popular culture and their stronghold and a lot of social media, the palette is so diverse, the markets are so varied, that trends go in many different directions. So we need to sometimes think about who we are speaking about, what the superpower of the day is, and whenever we make these generalizations, what are the limitations? Who's not included in them?"

In addition to her role at Curtin, Abidin founded the TikTok Cultures Research Network and is an affiliate researcher with the Media Management and Transformation Centre at Jönköping University. She was named an Australian Research Council DECRA Fellow for 2019 to 2024. Currently the editor-in-chief of Media International Australia, she has written or edited a number of books that bridge popular concerns with academic rigor, including 2018's Internet Celebrity: Understanding Fame Online and this year's Influencer Marketing: Interdisciplinary and Socio-Cultural Perspectives (co-edited with Lauren Gurrieri and Jenna Drenten),

Everyone, we assume, wants to be their best person. Few of us, perhaps, none, hits all their marks in this pursuit even if the way toward the goal is generally apparent. If you want to know how to do a better job hitting those marks, whether its walking 10,000 steps, learning Esperanto, or quitting smoking, a good person to consult would be Katy Milkman. Working at the nexus of economics and psychology, Milkman – the James G. Dinan Professor at The Wharton School of the University of Pennsylvania and co-founder of the Behavior Change for Good Initiative at Penn – studies the almost alchemical process of turning good intentions into solid actions.

In this Social Science Bites podcast, she details for interviewer David Edmonds some of the biases and some of the critical thinking processes that both define and then overcome the obstacles to changing our behavior. These range from concepts with such academic names as present bias and temptation bundling to the more colloquial 'what the hell effect' and its antidote, the emergency reserve. But the point of her research – especially as it gets translated to the public through her podcast Choiceology or her 2021 book How to Change: The Science of Getting from Where You Are to Where You Want to Be – is to find practical ways to change yourself.

For example, she explains that "it's important for goals to be measurable and achievable, although they should be a stretch. You know, if your goal is 'exercise more,' how can you measure that? How could you even set a commitment device, for instance? … It's also important to have a plan of, sort of, when will I do it, where will I do it, how will I get there. These are called "implementation intentions." I think the most important part of them is they associate a cue with the action. So just like an actor needs a cue to know when to say their lines, we need to not forget to take action on our goals."

Her influence in turn is felt practically. Choiceology, for example, is sponsored by the brokerage house Charles Schwab, and Milkman has been a consultant for organizations ranging from the U.S. government and Walmart to 24 Hour Fitness and the American Red Cross. She is a former president of the Society for Judgment and Decision Making and a fellow of the Association for Psychological Science.

There is a natural desire on the part of governments to ensure that their future citizens -- i.e. their nation's children -- are happy, healthy and productive, and that therefore governments have policies that work to achieve that. But good intentions never guarantee good policies.

Here's where economist Janet Currie steps in. Currie is the Henry Putnam Professor of Economics and Public Affairs at Princeton University, where she co-directs, with Kate Ho, the Center for Health and Wellbeing. In this Social Science Bites podcast, the pioneer in assessing the nexus of policy and parenting explains to interviewer David Edmonds how programs like Head Start in the United States and Sure Start in the United Kingdom provide real benefits over time to both their young clients as youths and later on in life.

After looking at a variety of programs and interventions, she details that "the general conclusion [is] that the programs that were spending more money directly on the children tended to have better outcomes."

Her findings suggest this holds true even when similar approaches don't have the same effect on adults. "[I]n the United States," she says, "if you give health insurance to adults who didn't have health insurance, they use more services, and they are happier about that, that they get to use services. But it doesn't actually seem to save very much money. On the other hand, when you cover children from a young age, that is cost effective, that does save money, and in fact, the costs of the program probably pay for themselves in terms of the reduction in illness and disability going forward."

In addition to her work at Princeton, Currie is also co-director of the National Bureau of Economic Research's Program on Families and Children. She has been president of the American Economic Association for 2024 and has also served as president of the American Society of Health Economics, the Society of Labor Economics, the Eastern Economic Association, and the Western Economic Association. Two years ago, she received the Klaus J. Jacobs Research Prize "for her foundational work on the influence of context such as policy decisions, environment, or health systems on child development."

As an investigative journalist, Julia Ebner had the freedom to do something she freely admits that as an academic (the hat she currently wears as postdoctoral researcher at the Calleva Centre for Evolution and Human Sciences at the University of Oxford) she have been proscribed from doing - posing as a recruit to study violent extremist groups. That, as you might expect, gave her special insight into how these groups attract new blood, and on the basis of that work, as well as more traditional research for groups such as the Quilliam Foundation and the Institute for Strategic Dialogue, she has been hosted by the United Nations, national legislators, intelligence agencies and Big Tech.

In this Social Science Bites podcast, Ebner details some of the mechanics of her undercover research for host David Edmonds before discussing the prevalence and characteristics of violent extremist groups. Given the variety of ways governments tally these groups and the groups' own amorphousness in an online age, determining whether such groups are on the rise - which seems to be a perennial fear - proves devilishly difficult to determine. "I would say," Ebner concedes, "it often comes and goes in waves, but now we are seeing a very strong wave of very young people, including minors, radicalizing towards violence."

That radicalization proves remarkably similar regardless of ideology, Ebner notes. Plus, it's not straightforward determining who might be open to recruitment. "Based on my research, I would say that everyone is potentially susceptible to radicalization, especially in vulnerable moments in our lives, and everyone has them."

Ebner serves up that potential universality in a different context to close the podcast. It's what keeps her up at night: "I think the mainstreaming of some of the extreme concepts and ideas and language that I used to observe only in the darkest corners of the internet, but that is now being heard in parliaments, that is now being seen in large social media channels of influencers or voiced by politicians."

Given her journalistic chops, it is no surprise that Ebner has written extensively on extremism in a series of well received books. The Rage: The Vicious Circle of Islamist and Far-Right Extremism, received the Bruno Kreisky Award for the Political Book of the Year 2018; Going Dark: The Secret Social Lives of Extremists was a Telegraph Book of the Year 2020 and Germany publishing's Wissenschaftsbuch des Jahres 2020 ("Science Book of the Year") Prise as well as the Dr Caspar Einem Prize from the Association of Social Democratic Academics; and Going Mainstream: How Extremists Are Taking Over, was published in 2023.

The relationship between citizens and their criminal justice systems comes down to just that - relationships. And those relations generally start with essentially one-on-one encounters between law enforcement personnel and individuals, whether those individuals are suspects, victims or witnesses.

When those relations get off on the wrong foot - or worse, as in the case of a number of high-profile police killings in the United States attest to - the repercussions can resonate far away from where a traffic stop occurs. This is the field that social psychologist Nick Camp researches. As his website at the University of Michigan explains, Camps studies "the role routine police-citizen encounters play in undermining police-community trust, and how these disparities can be addressed."

As he tells interviewer David Edmonds in this Social Science Bites podcast, "[O]ne of the things that we know from research and procedural justice is that when people don't view policing as legitimate, they're less likely to cooperate with police requests for assistance, for example. Until now, it's hard to find experimental evidence for this, but one of the things we can use body cameras for is not just to look at disparities in these interactions, but their consequences."

In this episode, Camp cites research on body camera footage, traffic stops, and even first names to describe how anecdotal tropes about often poor police-citizen interactions, especially in the African-American community, are borne out by the reams of data modern recording devices provide. He also offers hopeful signs of improving these relationships with training based on this very same data, and suggests that artificial intelligence might be useful in mining this data for more insights.

Listening to the ongoing debate about artificial intelligence, one could be forgiven for assuming that the technology is either a bogeyman or a savior, with little ground in between. But that's not the stance of economist Daron Acemoglu, professor at the Massachusetts Institute of Technology and the author, with Simon Johnson, of the new book Power and Progress: Our Thousand-Year Struggle Over Technology and Prosperity. Combining a cogent historical analysis of past technological revolutions, he examines whether a groundbreaking new technology "augments" the status quo, as opposed to merely squeezing out human labor.

"[M]y favorite term is 'creating new tasks' because I think it really clarifies what the quote unquote augmenting needs to take the form of," he tells interviewer David Edmonds in this Social Science Bites podcast. "It's not just making a worker more productive in tightening the screws, but it's really creating new jobs that didn't exist." And so, he explains to those perhaps afraid that a bot is gunning for their livelihood, "Automation is not our enemy. Excessive automation is our enemy."

This is not to depict Acemoglu as an apologist for our new silicon taskmasters. Current trends such as the consolidation of power among technology companies, a focus on shareholder returns at the expense of all else, a blind trust in companies to somehow muddle through to societal equilibrium, and a slavish drive to automate everything immediately all leave him cold: "I feel AI is going in the wrong direction and taking us down with it."

His conversation doesn't end there, thankfully, and he offers some hopeful words on how we might find that modus vivendi with AI, including (but by no means only relying on) "the soft hand of the state in tipping the scales one way or another."

Acemoglu is an elected fellow of the National Academy of Sciences, the American Philosophical Society, the British Academy of Sciences, the Turkish Academy of Sciences, the American Academy of Arts and Sciences, the Econometric Society, the European Economic Association, and the Society of Labor Economists. He is also a member of the academic-cum-policymaker group of economic movers and shakers known as the Group of 30.

Besides Power and Progress, his books include the popular bestseller Why Nations Fail: Power, Prosperity, and Poverty written with James Robinson. Acemoglu has received a number of prizes, including two inaugural awards in 2004, the T. W. Shultz Prize from the University of Chicago and the Sherwin Rosen Award for outstanding contribution to labor economics. He received the John Bates Clark Medal in 2005, the Erwin Plein Nemmers Prize in 2012, and the 2016 BBVA Frontiers of Knowledge Award, as well as the Distinguished Science Award from the Turkish Sciences Association in 2006 and a Carnegie Fellowship in 2017.

How much of our understanding of the world comes built-in? More than you'd expect.

That's the conclusion that Iris Berent, a professor of psychology at Northeastern University and head of the Language and Mind Lab there, has come to after years of research. She notes that her students, for example, are "astonished" at how much of human behavior and reactions are innate.

"They think this is really strange," she tells interviewer David Edmonds in this Social Science Bites podcast. "They don't think that knowledge, beliefs, that all those epistemic states, could possibly be innate. It doesn't look like this is happening just because they reject innateness across the board."

This rejection – which affects not only students but the general public and sometimes even social and behavioral scientists -- does have collateral damage.

So, too, is misinterpreting what the innateness of some human nature can mean. "[I]f you think that what's in the body is innate and immutable, then upon getting evidence that your depression has a physical basis, when people are educated, that psychiatric disorders are just diseases like all others, that actually makes them more pessimistic, it creates more stigma, because you think that your essence is different from my essence. … [Y]ou give them vignettes that actually underscore the biological origin of a problem, they are less likely to think that therapy is going to help, which is obviously false and really problematic"

Berent's journey to studying intuitive knowledge was itself not intuitive. She received a bachelor's in musicology from Tel-Aviv University and another in flute performance at The Rubin Academy of Music before earning master's degrees in cognitive psychology and in music theory – from the University of Pittsburgh. In 1993, she received a Ph.D. in cognitive psychology from Pittsburgh.

As a researcher, much of her investigation into the innate originated by looking at language, specifically using the study of phonology to determine how universal – and that includes in animals – principles of communication are. This work resulted in the 2013 book, The Phonological Mind. Her work specifically on innateness in turn led to her 2020 book for the Oxford University Press, The Blind Storyteller: How We Reason About Human Nature.

Do policies built around social and behavioral science research actually work? That's a big, and contentious, question. It's also almost an existential question for the disciplines involved. It's also a question that Megan Stevenson, a professor of law and of economics at the University of Virginia School of Law, grapples with as she explores how well randomized control trials can predict the real-world efficacy of interventions in criminal justice. What she's found so far in that particular niche has echoed across the research establishment.

As she writes in the abstract of an article she saw published in the Boston University Law Review:

"This Essay is built around a central empirical claim: that most reforms and interventions in the criminal legal space are shown to have little lasting effect when evaluated with gold standard methods. While this might be disappointing from the perspective of someone hoping to learn what levers to pull to achieve change, I argue that this teaches us something valuable about the structure of the social world. When it comes to the type of limited-scope interventions that lend themselves to high-quality evaluation, social change is hard to engineer. Stabilizing forces push people back towards the path they would have been on absent the intervention. Cascades—small interventions that lead to large and lasting changes—are rare. And causal processes are complex and context-dependent, meaning that a success achieved in one setting may not port well to another."

In this Social Science Bites podcast, Stevenson tells interviewer David Edmonds that "the paper is not saying 'nothing works ever.' It's saying nothing works among this subset of interventions, and interventions, as we talked about, are the type of interventions that get studied by randomized control trials tend to be pretty limited in scope. You can randomly allocate money, but you can't randomly allocate class or socioeconomic status."

Despite this cautionary finding in her research. Stevenson hasn't despaired about her career choice or that of other social and behavioral scientists. "Many of us are in this line of work because we care about the world," she notes. "We want to make the world a better place. We want to think about the best way to do it. And this is valuable information along that path. It's valuable information in that it shuts some doors. … So keep trying other doors, keep experimenting."
