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.
