Between a series of high-profile shootings of black men by police and the election of Donald Trump by a bifurcated electorate, the racial divide in the United States has achieved a renewed public prominence. While discussion of this divide had faded since the election of Barack Obama, it’s an issue that has always been at the forefront of the scholarship of Harvard’s Jennifer Hochschild.

In this Social Science Bites podcast, Hochschild explains to interviewer David Edmonds some of the pertinent data points from her years of using quantitative and qualitative analysis to map the racial, ethnic and class cleavages in America’s demography.

The issues are devilishly difficult to address in, well, black-and-white terms, it turns out, as Hochschild repeatedly answers “yes and no” to various questions. Academics, she explains, tend to generalize too much about these issues, to focus too much on the role of the federal government to the detriment of state governments, and don’t pay enough attention to spatial variations: “Los Angeles doesn’t look like Dubuque, Iowa.”

She depicts a racial continuum of acceptance and opportunity, with whites and Asians at one extreme, blacks at the other, and other communities, such as Latinos and Muslims, populating the expanse in between. While the distance between the extremes seems to be as wide as it’s been for the last half century, she sees some hopes in the middle. She draws parallels for the modern Latino community with that of immigrants from Eastern and Southern Europe at the turn of the last century: they arrived as ‘lesser whites’ but at this point have full membership in the larger dominant community.

Hochschild talks specifically about the Muslim immigrant community in the U.S., with its wide range of homelands and ethnicities but a generally high level of education. She expects the community’s traditional low level of political activity to change dramatically in the near future. “My guess is that’s going to change over the next decade as they increasingly feel not only beleaguered but in real trouble. From my perspective, I hope there will be more alliances with other groups, but that remains to be seen”

Hochschild is the Henry LaBarre Jayne Professor of Government at Harvard University, where she focuses on African and African American studies. The author of several important books on race and politics, she was also the founding editor of Perspectives on Politics, published by the American Political Science Association, and was a former co-editor of the American Political Science Review. Earlier this year she completed her one-year term as president of the APSA.

Where did the first viruses come from? They have the potential to wipe out life on Earth. But could life on Earth itself have evolved from the first viruses? Like the chicken and the egg, there are fierce arguments about which came first and rival scientists get quite cross about it all.

We take a dip into the primordial soup of creation and try to answer listener Ian's excellent question. Along the way, we revisit medieval plagues, travel to Texas to the largest urban bat colony in the world and take a walk through the dense mosquito-infested Ugandan forest that gave its name to the Zika virus.

Plus, we reveal how a virus is responsible for the placenta. No virus, no placenta; no placenta, no humans?

This programme has been edited since broadcast to remove a brief reference to ‘bubonic plague’ being included in a list of viral diseases.

How much electric energy storage would it take to run the average home for 24 hours? Also: When will it be economical to locally store several days of electric energy for our home? Listener Gus in Texas, USA, wants to know – especially because he’s one of many people around the world who sometimes face lengthy power cuts.

Presenter Marnie Chesterton takes Gus’s question to energy experts. She heads to two national research facilities: The National Grid Scale Energy Storage Lab at University College London, and the Joint Center for Energy Storage Research at Argonne National Laboratory near Chicago – which originated from the early stages of the Manhattan Project. On the way, Marnie finds out where the word ‘battery’ came from, discovers why our mobile phone batteries gradually die with age, and hears how the next generation of power storage could change the world.

Is it possible to get power from lightning? This was the first CrowdScience question posed by listener John Emochu in Kampala, Uganda.

Presenter Marnie Chesterton goes hunting for the answer at a lightning lab in Cardiff, Wales. What is a lightning lab? And how was she able to make a tiny – but very loud – lightning bolt? Marnie also discovers humanity's early history with lightning, how aeroplanes are protected from lightning strikes, and where the greatest number of thunderstorms occur in the world.

With contributions from John Emochu, Rhys Phillips, Chris Stone, Rachel Albrecht, Shaaron Jimenez and Manu Haddad.

Imagine if we could find the secret to romance and love, the real secret, one vetted by science. Wouldn’t that be … well, what would that be. According to Anna Machin, an anthropologist who actually does study romance, it would be disheartening.

“I don’t want to find the formula for love,” she tells interviewer Dave Edmonds in the latest Social Science Bites podcast. “I think that would be incredibly depressing.”

But Machin, a professor at the University of Oxford and part of an experimental psychology research group run by another Social Science Bites alumnus, Robin Dunbar, is nonetheless fascinated by how evolution has created this thing we call love, using the tools of neurochemistry and qualitative social science. Her research ranges from “our primate cousins” to popular dating sites. And before you insert your own joke here, know that these two examples have more in common than you might think.

Distinct primate-centric patterns quickly emerge in dating site profiles, Machin explains. For men, it’s displaying their value – their status, resources and good genes. For women, it’s their fertility, including youth, and good genes – regardless of their own wealth or status.

Not, she cautions, that we’re exactly like the rest of the menagerie. “The relationships we build, the reproductive relationships, our romantic relationships, are categorically different to those in other animals,” she says. “They persist for much longer, the cognition involved is much more complex,” and the neurochemistry doesn’t explain how we can stick together for such an incredibly long period of time.

Machin’s own academic background is varied, beginning with bachelor’s work in anthropology and English and leading to a PhD, in Archaeology, from the University of Reading (her thesis was on Acheulean handaxes). As an academic, she delights in explaining her work to the public, an avocation that has including working with the TV show Married at First Sight, where she’s used her own scholarship to help participants find life partners.

The culture of dance clubs has a way of popping up in policy debates around the world. In September, for example, the closure of London’s Fabric nightclub – called “one of the most influential and internationally renowned electronic music venues on the planet” by a major newspaper half that planet away – created a huge debate. In Los Angeles in July, the deaths of three people at the Hard Summer Music Festival -- on the heels of more than two dozen drug-related deaths at raves across the U.S. Southwest in the past decade -- saw enormous (but unsuccessful) efforts to ban the electronic dance music festivals.

Dance culture, then, isn’t just frippery, it’s policy.

That’s no surprise to Karenza Moore, the guest of the latest Social Science Bites podcast. Moore, a lecturer in sociology at Lancaster University, has for more than a decade studied and written about the dance clubs, the music they play, and the drug use she says the culture has “hidden in plain sight.” Her interests are purely academic; Moore describes herself as a “participant observer” with at least 20 years standing on the dance floor.

In conversation with David Edmonds, Moore makes no bones about the prevalence of drugs in the club scene – even if alcohol is the most used drug in the post-rave era. MDMA, whether known as ecstasy , E, Molly, is used as a matter of routine, which she says “needs to be acknowledged.” Her sociological ethnography of the scene and its drug use sees her reject purely prosecution-oriented responses to that acknowledgement. Drawing from what she calls ‘critical drug studies,’ sees, Moore suggests that violence attributed to the clubs is linked to the underground drug trade, not the more-or-less open drug use. “Prohibition causes more harm than good,” Moore tells Edmonds, by placing a matter of public health in the hands of people who have no regulation to abide by.

In the podcast, Moore also talks about the mechanics of interviewing club-goers – seems many have a desire to overshare their exploits – and how long ‘participant observers’ can keep observing in a culture that’s generally reckoned to focus on youth.

At Lancaster, Moore runs the aptly named Club Research as a hub for research on all the drugs, legal, illicit and novel, in the scene, as well the various subcultures and the larger “night-time economy.” A lot of that work appears at her blog, http://www.clubresearch.org/, and is covered in her contributions as co-author to the 2013 book from SAGE publishing, Key Concepts in Drugs and Society.

“One of the values of the social sciences,” argues Michael Billig, “is to investigate what people take for granted and to bring it to the surface.” In this Social Science Bites podcast, Billig, a professor of social science at Loughborough University since 1985, discusses a particular strain of something taken for granted, what he terms “banal nationalism.” That refers to the idea that much of what we would consider markers of the nationalistic impulse pass without notice, the “unwaved flags” we’d only notice if they disappeared.

In his conversation with interviewer David Edmonds, Billig dives more deeply into one particular example of nationalism, the British royal family, and what the British themselves think about the royal  family and the place of the royals in British ideology.  

Drawing on what he learned while supervising the qualitative surveys of average British citizens that formed the basis of his 1992 book Talking of the Royal Family, he suggests that the British people, while much less deferential to the royals than outsiders might think, tend to accept that the RF is a good thing and therefore sympathize with them – as long as the public perceives the family as publicly suffering from their privilege.

As he tells Edmonds, it was while doing that project that he realized he in fact was writing about nationalism when he write that book, which started him down the road to his 1995 book, Banal Nationalism. Since then he’s addressed a number of other topics, including laughter, rock ‘n’ roll, and how to write badly – a topic that concludes the podcast. He also defends the role of social scientists – trained as a social psychologist he prefers to describe himself using the broader term by citing the ephemerality of the findings. “The idea that you may get eternal truths from social science is a bit of a mythology,” he insists. “This is why you always need social scientists.”

It's often remarked that technology has made the world a smaller place. While this has been especially true for those with the wherewithal to buy the latest gadget and to travel at will, but it's also true for economic migrants. Those technological ties are one of the key research interests of Mirca Madianou, a reader in the Department of Media and Communications at Goldsmiths, University of London.

In this Social Science Bites podcast, Madianou details several foundational shifts "transnational families," those families where breadwinners -- and prospective breadwinners -- head far away to help support their family members back home. She's charted both an intensification of global migration, and also the feminization of migration -- women are as likely to migrate as men. And in the last decade, communication allows those women to "mother at a distance," a very signal change from the days when the only contact a family member might be able to muster at will was a fraying photograph.

In conversation with David Edmonds, Madianou also addresses "humanitarian technologies" -- the ability to reunite people pulled apart by crisis or disaster. While these technologies serve as beacons and also monitors of charitable response, they also provide a forum for emotional discharge, she explains. "... [T]his digital footprint, this digital identity, ... became the focal point for mourning rituals and for grieving, and that was a very important function that social media played."

Madianou joined Goldsmiths in 2013, and for two years before that was a senior lecturer at the University of Leicester. From 2004 to 2011 she taught at the University of Cambridge, where she was Newton Trust Lecturer in Sociology and Fellow of Lucy Cavendish College. She wrote 2011's Migration and New Media: transnational families and polymedia (with Daniel. Miller) and 2005's Mediating the Nation: News, audiences and the politics of identity, in addition to be an editor for 2013's Ethics of Media.

While intentional bias generally is an ugly thing, it's also relatively easy to spot if the will exists to do so. But what about bias where individuals or institutions haven't set out to discriminate -- but the net effect is bias? "[M]uch of discrimination is in fact based on unconscious or implicit bias," says Iris Bohnet, a behavioral economist at Harvard Kennedy School, "where good people like you and me treat people differently based on their looks." At times, even the subjects of implicit bias in essence discriminate against themselves.

The Swiss born Bohnet, author of the new book What Works: Gender Equality by Design, studies implicit bias in organizations. In this Social Science Bites podcast, Bohnet tells interviewer David Edmonds that even good-faith efforts to address this bias has so far found little evidence that many of the structural remedies tried so far do in fact have an effect on the underlying bias. This doesn't mean she opposes them; instead, Bohnet works to design effective and proven solutions that work to "de-bias" the real world.

Bohnet received her Ph.D. in economics from the University of Zurich in 1997 and joined the Harvard Kennedy School in 1998, where she has served as the academic dean of the Kennedy School, is the director of its Women and Public Policy Program, the co-chair (with Max Bazerman) of the Behavioral Insights Group, an associate director of the Harvard Decision Science Laboratory, and the faculty chair of the executive program “Global Leadership and Public Policy for the 21st Century” for the World Economic Forum’s Young Global Leaders. She serves on the boards of directors of Credit Suisse Group and University of Lucerne.
