On being MIXED

Chances are, you have not felt betrayed by a Google form. But if you’re part of the 8% of multiracial students at Duke, perhaps you’re familiar.

If you check one box, it feels like you deny your identity as another. It is a constant battle of representation, of feeling a responsibility towards all of your communities while simultaneously feeling an imposter in all of them. There is always the issue of being too white for one group, too brown for another.

Since 2012, every county in the United States has reported a multiracial population. Dr. Sarah Gaither, an assistant professor of psychology & neuroscience at Duke, studies the identity crisis multiracial students face. In 2015, she published “‘Mixed’ Results: Multiracial Research and Identity Explorations” in Current Directions in Psychological Science. And on February 10, she organized a screening of MIXED, a documentary following the struggles and backlash facing mixed-race families. The film’s directors, Caty Borum and Leena Jayaswal of American University, joined the screening and provided a Q&A session for the audience.

Gaither’s research is featured in the film, as well as Duke SWIRL (Students With Interracial Legacies), a former student organization.

“Multiracials who identify as multiracial actually experience decreased self-esteem when asked to choose only one racial identity,” Gaither notes in her article. Sure enough, the documentary follows America’s slow response to progress. Despite being in the aftermath of our first biracial president, despite it being over 50 years since Loving v. Virginia, which legalized interracial marriage nationwide, there have only been two U.S. Censuses taken since the Census Bureau allowed more than one race to be checked on official forms. This caused a notable shift; between 2000 and 2010, the number of reported interracial people increased by 32%, likely because of the ability to “claim more than one race” as a legal identity.

Gaither’s research in the Duke Identity and Diversity Lab pledges to continue this research. She notes interesting extensions of multiracial identities, such as Latinx students and families who are subject to even more confusing checkboxes on aforementioned Google forms (What is your race and ethnicity? Because “Hispanic/Latino” is its own category).

“The process of racial self-identification can be more challenging as racial categories can be complex and/or ambiguous,” Gaither says. She also notes the identity crises genderqueer people face, and how restricting checkboxes can really be.

The documentary provides the viewer an opportunity to experience the inequities and bigotries that still exist toward multiracial families. Race, after all, is genetically irrelevant. The documentary team gives examples of questions they are often asked:


“Are you the nanny?”
“What is she?”
“Did you adopt those children?”
“Where did they come from?”


And I’ll add a few more, from experience:


“It’ll be two separate checks today?”
“Where do you get that hair from?”
“Is this your aunt?”


The point is: racial divides are projected by outsiders onto mixed families, and it creates a crisis of identity for mixed-race individuals. It is a phenomenon well documented by Gaither, Borum, Jayaswal, and others who have lived it.

“Humans Are Selectively Pro-science” and Other Ways to Think About Polarization

Photo from DonkeyHotey on flickr.com. Licensed under Creative Commons license.

We live in a country where 80% of both Democrats and Republicans believe that the other political party “poses a threat that if not stopped will destroy America as we know it.” Lovely.

A 2020 study found that only 3.5% of voters would avoid voting for their preferred candidate if that candidate engaged in undemocratic behavior. In 2022, 72% of surveyed Republicans said that Democrats are more immoral than other Americans, and 83% of Democrats said that Republicans are more close-minded than other Americans. Political polarization is apparently increasing faster in the U.S. than in other democracies, but Americans aren’t just divided along political lines. Other aspects of identity, like religious beliefs, can spawn discord as well. In the U.S., 70% of atheists think religious organizations “do more harm than good,” but 44% of Americans still think that you must believe in God “in order to be moral and have good values.”

Most Americans agree that polarization is a problem. But what can be done about it? The Trent Center for Bioethics, Humanities, and History of Medicine recently hosted a conversation between two people who have spent much of their careers engaging with many different beliefs and perspectives. A recording of the talk can be found here.

Molly Worthen, Ph.D., Associate Professor of History at UNC and a freelance journalist, grew up in a “secular, totally nonreligious home,” but courses she took in college made her realize that “for a huge swath of humanity, over the course of our history,” religion has helped people find meaning and community. She has explored religion extensively through her work as a historian, author, and journalist. Worthen says she has “way too risk-averse a temperament to be a full-time journalist,” but one advantage of journalism is that it provides “an excuse to ask people questions.”

Emma Green, a journalist at The New Yorker, has also covered religion in her writing and spent time engaging with people and communities who hold a wide variety of beliefs. Green believes that “the most interesting stories are often about the debates communities are having within themselves.” These debates aren’t just about religion. In communities of all kinds, people with different and often opposing beliefs navigate disagreements with their best friends, neighbors, and family members as they engage with polarizing issues and try to find ways to coexist.

The process of interviewing people with differing worldviews and beliefs can bring challenges, but both Worthen and Green have found that those challenges are not insurmountable. “If you do your homework and you really make a good-faith effort to learn where a person is coming from,” Worthen says, “they will tell you their story. They will not shut down.”

Worthen has spent time with a community of Russian Orthodox Old Believers in Alberta. It was an opportunity to make a “concerted effort to really get inside the worldview of someone very different from myself.”

Green has also spent time talking to and learning from religious communities. She published an article about Hyattsville Mennonite Church in Pennsylvania, which had been welcoming gay members for over a decade and had originally been “disciplined” by the Allegheny Mennonite Conference for its open acceptance of homosexuality. A decade later, the Conference gathered to determine whether the Hyattsville church should be allowed to rejoin the Conference or be removed from it altogether. (A third option, according to Green’s article, was to dissolve the Conference.) Green was struck by how the Mennonite community approached the dispute. They followed the formal “Robert’s Rules of Order,” but they also sang together in four-part harmony. The central dispute, Green says, was “about whether they could stay in community with one another.” Ultimately, the gay members were allowed to stay, though Green says that some people left the congregation in protest.

Polarization is a word we hear a lot, but why is it that we seem to have such a hard time finding common ground when it comes to important—or even seemingly unimportant—issues? Worthen points out that there seems to be a new survey every few years showing that “humans are generally impervious to evidence” that goes against our existing beliefs.

“Barraging a human with evidence doesn’t really work,” Worthen says. According to her, theologians and philosophers have long said that “we are depraved, irrational creatures, and the social science has finally caught up with that.”

This hesitancy to even consider evidence that conflicts with our existing beliefs has implications on public trust in science. Too often, “believing in science” takes on political implications. 

According to Pew Research Center, only 13% of Republicans have “a great deal” of confidence in scientists, compared to 43% of Democrats. “Many people on the left think of the universities as belonging to them,” says Worthen, leading to a greater sense of trust in science. “There is a desire on the left to want science to line up” with their political views, Green agrees, but good science isn’t inherently aligned with a particular political party. Science involves uncertainty and “iterative self-correction,” Worthen says, but even acknowledging uncertainty can spawn controversy. And when science doesn’t perfectly align with someone’s political or ideological beliefs, it can make people uncomfortable. For instance, Worthen believes that “the retreating date of viability” for fetuses and better fetal imaging technology is “provoking… discomfort on the left” in conversations about abortion.

Similarly, evidence from evolutionary biology can be hard to reconcile with deeply held religious beliefs. Worthen describes an interview she did with Dr. Nathaniel Jeanson. He has a Ph.D. from Harvard in cell and developmental biology, but he is also a Young Earth creationist who believes the earth was created by God in six days. There are “plenty of conservative Christians who understand those days as metaphors,” Worthen says, but Jeanson takes the six-day timeframe described in the Bible literally. In Worthen’s article, she says that Jeanson “dutifully studied evolutionary biology during the day and read creationist literature at night.” One thing Worthen admired in Jeanson was his willingness to be “honest about who we are”: not very open to new evidence.

“I think very few humans are anti-science,” Worthen says. “It’s more that humans are selectively pro-science.”

It isn’t just politics that can cause people to distrust science. Green points out that people who have had frustrating experiences with traditional healthcare may look for “other pathways to achieving a sense of control.” When patients know that something is wrong, and mainstream medicine fails them in some way, they may turn to alternative treatments. “That feeling of not being understood by the people who are supposed to know better than you is actually pretty common,” Green says, and it can fuel “selective distrust.”

It can be helpful, Worthen says, for a clinician to present themselves as someone trustworthy within a larger system that some patients view as “suspect.”

Distrust in public health authorities has been a recurring theme during the Covid pandemic. Green recalls interviewing an orthodox Jewish man in New York about his community’s experiences during the pandemic. Many Orthodox Jewish communities were hit hard by Covid, and Green believes it’s important to recognize that there were many factors involved. Even well-meaning health officials often lacked the language skills to speak dialects of Yiddish and other languages, and the absence of strong, pre-existing relationships with Orthodox communities made it harder to build trust in the middle of a crisis.

Worthen spoke about vaccine hesitancy. “For most of the population who has gotten the [Covid] vaccine,” she says, “it’s not because they understand the science but because they’re willing to ‘outsource’” their health decisions to public health authorities. It is “important not to lose sight of… how much this is about trust rather than understanding empirical facts.”

Finally, both speakers discussed the impacts of social media on polarization. According to Green, “information ecosystems can develop in social media and become self-contained.” While “there are a lot of people out there who are quacks who purport to be experts,” social media has also created public health “stars” who offer advice and knowledge to a social media audience. Even that, however, can have downsides. “There isn’t a lot of space for uncertainty, which is a huge part of science,” Green says.

Worthen, meanwhile, believes that “social media is one of the main assets destroying our civilization…. I would encourage everyone to delete your accounts.”

Polarization is pervasive, dangerous, and difficult to change. “As a journalist, I basically never have answers,” Green says, but maybe learning from journalists and their efforts to understand many different perspectives can at least help us begin to ask the right questions. Learning to actually listen to each other could be a good place to start.

What Should We Do with the Works of “Immoral Artists”?

How should we engage with books, songs, or other works of art created by artists, dead or alive, who have done bad things or hold morally problematic views?

The list of artists who have been accused of doing or saying disparaging, criminal, or morally reprehensible things is long. Paul Gauguin. Michael Jackson. Woody Allen. J.K. Rowling. Kanye West. Pablo Picasso. R. Kelly. Louis C.K. Bill Cosby. Many more.

J.K. Rowling, the author of the landmark Harry Potter series, has become controversial because of her 2020 tweets about transgender people.

It’s one thing to firmly condemn their actions and reject their beliefs. But what should we do with their art—as individuals and as institutions?

The Kenan Institute of Ethics recently held a conversation to discuss exactly that issue. The discussion was moderated by Jesse Summers, Ph.D., and featured speakers Erich Hatala Matthes, Ph.D., Associate Professor of Philosophy at Wellesley College and author of “Drawing the Line: what to do with the work of immoral artists from museums to the movies,” and Tom Rankin, Professor of the Practice of Art and Documentary Studies and Director of the MFA in Experimental and Documentary Arts at Duke University.

Why should we care about morality in art, anyway? Why not just appreciate the art and separate it from the artist?

Matthes believes that in some cases, “to not engage with the moral dimensions of a work would be to not take the work seriously.” He thinks Shakespeare’s works belong in this category. “Trickier cases,” he adds, “might come from works that aren’t explicitly engaged” with morality, but even in those cases, “the moral life of the artist can actually become a lens through which to read aspects of the work.”

We already consider context when viewing art, not just “formal features of the work.” What was the artist responding to? What were the politics at the time? Matthes believes it makes sense to consider the “moral life” of the artist, too. That “doesn’t mean the artist’s moral life is always going to be relevant” to engaging with the art, but he thinks it’s worth at least acknowledging.

According to Rankin, “When we look at a piece of art or hear something, what we hope is that it propels us” to consider moral issues. How, he asks, can we not look at a painting or photo and wonder, “Where did this come from? Who made it? What was their agenda? What is their point of view? What was their background?”

So where does that leave us, Rankin asks, when it comes to “work that was made a hundred years ago but is really powerful… and yet when we look at it a hundred years later it has all kinds of flaws?” Should museums remove paintings by famous artists if racist or sexist views come to light? Should individuals boycott books, songs, and video games created (or inspired) by artists who have made harmful statements toward individuals or groups of people? How should college classes address works by immoral artists?

Matthes says the term “immoral artists” in his book is intentionally provocative. “I don’t actually think it’s productive” to think of people as good or bad, moral or immoral, he says. “There’s a huge range” in the morality or lack thereof in artists’ actions, and Matthes believes there should also be a range in our responses, but he doesn’t believe that “great art can ever just excuse immorality.” He wants to reject the idea that “artists need to be a little inhuman” and “outside the norms of society.” He thinks that mindset encourages us to think of artists as not subject to the same rules. They should not be “immune to moral criticism,” he says.

Rankin agrees: “I do balk a little bit at having to be the one to decide who’s bad and who’s good,” but at the same time, he believes that “artists make work in response to who they are.” So “What do we confront first? The life of the artist or the work itself? It’s not one or the other,” he says.

Both speakers believe that context is often key to interpreting and evaluating art. Matthes says that it might be “really obscene” to choose Michael Jackson music at your wedding if you know one of your guests has experienced child abuse, given the child sexual assault allegations against Jackson. However, Matthes doesn’t believe that completely “cancelling” Jackson’s music is the solution, either.

Similarly, Matthes doesn’t believe that “we should necessarily continue with big exhibitions honoring Paul Gauguin,” a painter who had sexual relationships with young girls and employed racist terminology. According to Matthes, Gauguin “represents a paternalistic energy of a particular time” that we should “interrogate.” As for the notion that we should extend a degree of lenience to historical artists and view them as a product of their times, Matthes is “disinclined” to think of morality as relative to time period. The time when a work of art was created might affect how we engage with it or assign blame, but “Gauguin did a lot of morally horrific things, and the fact that it was in a different time and place doesn’t change that.”

Nevertheless, Matthes thinks we can and should still engage with and respond to the work of “immoral artists.” His concern, he says, is that taking art off of walls and bookshelves and not talking about it “isn’t reckoning with the legacy.” He also doesn’t “see a reason to put certain types of art on a pedestal and treat them differently…. Artistic expression is a fundamental part of human life.”

What if an individual doesn’t want to engage with such art at all? What if the actions of an artist, dead or alive, are so objectionable to someone that they want nothing to do with it? Matthes is okay with that attitude, though he does think it’s “missing an opportunity.”

Completely disengaging from art on account of its creator’s moral life “feels like a way of not taking the moral criticism seriously,” Matthes says. “It’s not something you would be wrong to fail to do,” but he believes in engaging with moral issues, even those that “it would be easier to just ignore.”

Michael Jackson’s album Thriller sold 32 million copies in 1983.

But he acknowledges that personal identities can play a role in how or whether we engage with the work of immoral artists. Matthes believes it’s important to consider “the position you’re coming from” when you read or think about these issues. On the other hand, people and groups who may be more directly impacted by an artist’s problematic views “also have really thoughtful, nuanced ways” of engaging—or not engaging—with the art.

Matthes believes that “we have a lot of moral latitude when it comes to our individual engagement” with art. He finds it difficult to make the argument that reading, listening to, or viewing art in your own home is directly harmful to others, even if the artist in question is still alive.

Summers, meanwhile, points out that if someone is upset by an artist, there could be cases where “you’re taking it out on your friends… when you should be taking it out on the band.”

Institutions like universities, however, might need to take further considerations. “Different moral norms might apply,” Matthes suggests, “based on the positions of power we occupy.” Classrooms, for instance, are a “semi-public” space. They can help provide context in conversations about “morally problematic art” and encourage people to “think really carefully and critically.” If a class is going to engage with such topics, though, Matthes thinks it’s important to spell that out to students beforehand.

Powerful conversations can take place outside of classrooms, too — in book clubs and even informal conversations with friends. “You don’t want to let the moral concerns completely drive the bus” when engaging with art, Matthes says, “but I think it’s important not to ignore them.”

Rankin concludes by reminding us that it isn’t just artists who face decisions about how to respond to the world. For instance, even among those who don’t think of themselves as photographers, anyone who carries a cell phone is making choices every time they take a photo — about what they’re presenting and why.

For Weary Scholars, a Moment to Regroup, Reconnect…and Write

DURHAM, N.C. — English professor Charlotte Sussman doesn’t get much time in her role as department chair to work on her latest book project, an edited collection of essays on migration in and out of Europe.

“At least not during daylight hours,” Sussman said.

But a recent workshop brought a welcome change to that. Sussman was one of 22 faculty who gathered Dec. 13 for an end-of-semester writing retreat hosted by the Duke Faculty Write Program.

Duke faculty and staff gather for an end-of-semester writing retreat.

Most of them know all too well the burnout faculty and students face at the end of the semester. But for a few precious hours, they hit pause on the constant onslaught of emails, meetings, grading and other duties to work alongside fellow writers.

The participants sat elbow-to-elbow around small tables in a sunlit room at the Duke Integrative Medicine Center. Some scribbled on pads of paper; others peered over their laptops.

Each person used the time to focus on a specific writing project. Sussman aimed to tackle an introduction for her 34-essay collection. Others spent the day working on a grant application, a book chapter, a course proposal, a conference presentation.

“We have so many negative associations with writing because there’s always something more to do,” said associate professor of the practice Jennifer Ahern-Dodson, who directs the program. “I want to change the way people experience writing.”

Ahern-Dodson encouraged the group to break their projects into small, specific tasks as they worked toward their goals. It might be reading a journal article, drafting an outline, organizing some notes, even just creating or finding a file.

After a brief workshop, she kicked off a 60-minute writing session. “Now we write!” she said.

The retreat is the latest installment in a series that Ahern-Dodson has been leading for over 10 years. In a typical week, most of these scholars wouldn’t find themselves in the same room. There were faculty and administrators from fields as diverse as history, African and African American Studies, law, psychology, classics, biostatistics. New hires sitting alongside senior scholars with decades at Duke.

“I really like the diversity of the group,” said Carolyn Lee, Professor of the Practice of Asian and Middle Eastern Studies. “It’s a supportive environment without any judgement. They all have the same goal: they want to get some writing done.”

Sussman said such Faculty Write program get-togethers have been “indispensable” to bringing some of her writing projects over the finish line.

Participants say the program not only fosters productivity, but also a sense of connection and belonging. Take Cecilia Márquez, assistant professor in the Duke History Department. She joined the Duke faculty in 2019, but within months the world went into COVID-19 lockdown.

“This was my way to meet colleagues,” said Márquez, who has since started a writing group for Latinx scholars as an offshoot.

The writing retreats are free for participants, thanks to funding from the Office of the Dean of Trinity College of Arts and Sciences and the Thompson Writing Program. Participants enjoy lunch, coaching and community in what’s normally a solitary activity.

“I appreciate the culture of collaboration,” said David Landes, who came to Duke this year as Assistant Professor of the Practice in Duke’s Thompson Writing Program. “In the humanities our work is intensely individualized.”

Retreats are one of many forms of support offered by the Faculty Write program: there are also writing groups and workshops on topics such as balancing teaching and scholarship or managing large research projects.

“One of the distinguishing features of Faculty Write is the community that extends beyond one event,” Ahern-Dodson said. “Many retreats are reunions.”

After two hours of writing, Ahern-Dodson prompted the group to take a break. Some got up to stretch or grab a snack; others stepped outside to chat or stroll through the center’s labyrinth at the edge of Duke Forest.

It’s more than just dedicated writing time, Ahern-Dodson said. It’s also “learning how to work with the time they have.”

The retreats offer tips from behavioral psychology, writing studies, and other disciplines on time management, motivation, working with reader feedback, and other topics.

As they wrap up the last writing session of the day, Ahern-Dodson talks about how to keep momentum.

“Slow-downs and writing block are normal,” Ahern-Dodson said. Maybe how you wrote before isn’t working anymore, or you’re in a rut. Perhaps you’re not sure how to move forward, or maybe writing simply feels like a slog.

“There are some things you could try to get unstuck,” Ahern-Dodson said. Consider changing up your routine: when and where you write, or how long each writing session lasts.

“Protect your writing time as you would any other meeting,” Ahern-Dodson said.

Sharing weekly goals and accomplishments with other people can help too, she added.

“Celebrate each win.”

Ultimately, Ahern-Dodson says, the focus is not on productivity but on meaning, progress and satisfaction over time.

“It’s all about building a sustainable writing practice,” she said.

Ahern-Dodson leads an end-of-semester writing retreat for Duke scholars.

Coming soon: On Friday, Jan. 27 from 12-1 p.m., join Vice Provost for Faculty Advancement Abbas Benmamoun for a conversation about how writing works for him as a scholar and administrator. In person in Rubenstein Library 249 (Carpenter Fletcher Room)

Get Involved: Faculty and staff are invited to sign up for writing groups for spring 2023 here.

Traveling With Friends Helps Even Mixed-Up Migrators Find Their Way

New computer modeling research offers clues to how migrating animals get to where they need to go, even when their magnetic compass leads them astray. Credit: Jesse Granger, Duke University

DURHAM, N.C. — Some of us live and die by our phone’s GPS. But if we can’t get a signal or lose battery power, we get lost on our way to the grocery store.

Yet animals can find their way across vast distances with amazing accuracy.

Take monarch butterflies, for example. Millions of them fly up to 2,500 miles across the eastern half of North America to the same overwintering grounds each year, using the Earth’s magnetic field to help them reach a small region in central Mexico that’s about the size of Disney World.

Or sockeye salmon: starting out in the open ocean they head home each year to spawn. Using geomagnetic cues they manage to identify their home stream from among thousands of possibilities, often returning to within feet of their birthplace.

Now, new research offers clues to how migrating animals get to where they need to go, even when they lose the signal or their inner compass leads them astray. The key, said Duke Ph.D. student Jesse Granger: “they can get there faster and more efficiently if they travel with a friend.”

When their internal compasses go bad, migrating animals like these sockeye salmon don’t stop to ask directions. But they succeed if they stay with their fellow travelers. Credit: Jonny Armstrong, USGS

Many animals can sense the Earth’s magnetic field and use it as a compass. What has puzzled scientists, Granger said, is the magnetic sense is not fail-safe. These signals coming from the planet’s molten core are subtle at the surface. Phenomena such as solar storms and man-made electromagnetic noise can disrupt them or drown them out.

It’s as if the ‘needle’ of their inner compass sometimes gets thrown off or points in random directions, making it hard to get a reliable reading. How do some animals manage to chart a course with such a noisy sensory system and still get it right?

“This is the question that keeps me up at night,” said Granger, who did the work with her adviser, Duke Biology Professor Sönke Johnsen.

Multiple hypotheses have been put forward to explain how they do it. Perhaps, some scientists say, migrating animals average multiple measurements taken over time to get more accurate information.

Or maybe they switch from consulting their magnetic compass to using other ways of navigating as they near the end of their journey — such as smell, or landmarks — to narrow in on their goal.

In a paper published Nov. 16 in the journal Proceedings of the Royal Society B, the Duke team wanted to pit these ideas against a third possibility: That some animals still manage to find their way, even when their compass readings are unreliable, simply by sticking  together.

To test the idea, they created a computer model to simulate virtual groups of migrating animals, and analyzed how different navigation tactics affected their performance.

The animals in the model begin their journey spread out over a wide area, encountering others along the route. The direction an animal takes at each step along the way is a balance between two competing impulses: to band together and stay with the group, or to head towards a specific destination, but with some degree of error in finding their bearings.

The scientists found that, even when the simulated animals started to make more mistakes in reading their magnetic map, the ones that stuck with their neighbors still reached their destination, whereas those that didn’t care about staying together didn’t make it.

“We showed that animals are better at navigating in a group than they are at navigating alone,” Granger said.

Even when their magnetic compass veered them off course, more than 70% of animals in the model still made it home, simply by joining with others and following their lead. Other ways of compensating didn’t measure up, or would need to guide them perfectly for most of the journey to accomplish the same feat.

But the strategy breaks down when species decline in number, the researchers found. The team showed that animals who need friends to find their way are more likely to get lost when their population shrinks below a certain density.

Prior to the 1950s, tens of thousands of Kemp’s ridley sea turtles could be seen nesting near Rancho Nuevo, Mexico on a single day. By the mid-1980s the number of nesting females had dropped to a few hundred.

“If the population density starts dropping, it takes them longer and longer along their migratory route before they find anyone else,” Granger said.

Previous studies have made similar predictions, but the Duke team’s model could help future researchers quantify the effect for different species. In some runs of the model, for example, they found that if a hypothetical population dropped by 50% — akin to what monarchs have experienced in the last decade, and some salmon in the last century — 37% fewer of the remaining individuals would make it to their destination.

“This may be an underappreciated aspect of concern when studying population loss,” Granger said.

This research was supported in part by the Air Force Office of Scientific Research (FA9550-20-1-0399) and by a National Defense Science & Engineering Graduate Fellowship to Jesse Granger.

Duke’s Most-Cited — The Scholars Other Scientists Look To

It’s not enough to just publish a great scientific paper.

Somebody else has to think it’s great too and include the work in the references at the end of their paper, the citations. The more citations a paper gets, presumably the more important and influential it is. That’s how science works — you know, the whole standing-on-the-shoulders-of-giants thing.

So it always comes as a chest swelling affirmation for Dukies when we read all those Duke names on the annual list of Most Cited Scientists, compiled by the folks at Clarivate.

This year is another great haul for our thought-leaders. Duke has 30 scientists among the nearly 7,000 authors on the global list, meaning their work is among the top 1 percent of citations by scientific field and year, according to Clarivate’s Web of Science citation index.

As befits Duke’s culture of mixing and matching the sciences in bold new ways, most of the highly cited are from “cross-field” work.

Feeling Lonely? What We Want From Our Relationships Can Change With Age

Not feeling the holiday cheer this year? The gap between expectations and reality can leave people feeling lonely. Photo by madartzgraphics.

Not everyone’s holiday plans resemble a Hallmark card.

If the “most wonderful time of the year” isn’t your reality, you’re not alone. You might have an idea of a festive picture-perfect holiday season, but what actually transpires doesn’t always measure up.

And that’s where loneliness comes from, says King’s College London graduate student Samia Akhter-Khan, first author of a new study on the subject.

“Loneliness results from a discrepancy between expected and actual social relationships,” Akhter-Khan said.

Together with Duke psychology and neuroscience Ph.D. Leon Li, Akhter-Khan and colleagues co-authored a paper on why people feel lonely, particularly in later life, and what we can do about it.

“The problem that we identified in current research was that we haven’t really thought about: What do people expect from their relationships?” Akhter-Khan said. “We work with this definition of expectations, but we don’t really identify what those expectations are and how they change across cultures or over the lifespan.”

In every relationship, we expect certain basics. We all want people in our lives who we can ask for help. Friends we can call on when we need them. Someone to talk to. People who “get” us. Someone we can trust. Companions with whom we can share fun experiences.

But the team’s theory, called the Social Relationship Expectations Framework, suggests that older people may have certain relationship expectations that have gone overlooked.

Akhter-Khan’s first clue that the causes of loneliness might be more complex than meets the eye came during a year she spent studying aging in Myanmar from 2018 to 2019. At first, she assumed people generally wouldn’t feel lonely — after all, “people are so connected and live in a very close-knit society. People have big families; they’re often around each other. Why would people feel lonely?”

But her research suggested otherwise. “It actually turns out to be different,” she said. People can still feel lonely, even if they don’t spend much time alone.

What efforts to reduce loneliness have neglected, she said, is how our relationship expectations change as we get older. What we want from social connections in, say, our 30s isn’t what we want in our 70s.

The researchers identified two age-specific expectations that haven’t been taken into account. For one, older adults want to feel respected. They want people to listen to them, to take an interest in their experiences and learn from their mistakes. To appreciate what they’ve been through and the obstacles they have overcome.

They also want to contribute: to give back to others and their community and pass along traditions or skills through teaching and mentoring, volunteering, caregiving, or other meaningful activities.

Finding ways to fulfill these expectations as we get older can go a long way towards combating loneliness in later life, but research has largely left them out.

“They’re not part of the regular scales for loneliness,” Li said.

Part of the reason for the oversight may be that often the labor and contributions of older people are unaccounted for in typical economic indices, said Akhter-Khan, who worked in 2019-20 as a graduate research assistant for a Bass Connections project at Duke on how society values care in the global economy.

“Ageism and negative aging stereotypes don’t help,” she added. A 2016 World Health Organization survey spanning 57 countries found that 60% of respondents said that older adults aren’t well respected.

Loneliness isn’t unique to older people. “It is a young people’s problem as well,” Akhter-Khan said. “If you look at the distribution of loneliness across the lifespan, there are two peaks, and one is in younger adulthood, and one is an old age.”

Even before the COVID-19 pandemic, world leaders began sounding the alarm on loneliness as a public health issue. Britain became the first country to name a minister for loneliness, in 2018. Japan followed suit in 2021.

That’s because loneliness is more than a feeling – it can have real impacts on health. Persistent loneliness has been associated with higher risks of dementia and Alzheimer’s disease, heart disease and stroke, and other health problems. Some researchers suggest it’s comparable or riskier than smoking and obesity.

The researchers hope that if we can better understand the factors driving loneliness, we might be better able to address it.

“Of Sound Mind”: a Discussion of the Hearing Brain

“To me [this image] captures the wonder, the awe, the beauty of sound and the brain that tries to make sense of it,” said professor Nina Kraus, Northwestern University researcher and author of “Of Sound Mind: How Our Brain Constructs a Meaningful Sonic World.”

Stop. What do you hear?

We might not always think about the sounds around us, but our brains are always listening, said Northwestern University professor Nina Kraus.

Kraus, auditory researcher and author of “Of Sound Mind: How Our Brain Constructs a Meaningful Sonic World,” spoke via Zoom to a Duke audience in October. She has published more than four hundred papers on the auditory system in humans and other animals and how it’s affected by conditions like autism, aging, and concussion. She discussed some of her findings and how “the sound mind” affects us in our day-to-day lives.

One of the slides from Kraus’s presentation. We can think of sound as having many “ingredients.”

“I think of the sound mind as encompassing how we think, how we move, how we sense, and how we feel,” Kraus said. We live in a “visually dominated world,” but for hearing people, sound plays an important role in language, music, rhythm, and how we perceive the world.

One of the slides from Kraus’s presentation. The human auditory system involves not just the ears but also several regions of the brain. The “hearing brain” engages movement, cognition, and emotions along with interpreting direct sensory input from all senses.

Kraus discussed the auditory system and how much of what we think of as hearing takes place in the brain. We can think of sound as signals outside the head and electricity as signals inside the head (neural processing). When those two merge, learning occurs, and we can make sound-to-meaning connections.

Another slide from Kraus’s presentation. In an experiment, teaching rabbits to associate a sound with meaning (in this case, more carrots) changed patterns of neuron firing in the auditory cortex, even in individual neurons. “Same sound, same neuron, and yet the neuron responded differently… because now there’s a sound-to-meaning connection,” Kraus said.

Despite how sensitive our neurons and brains are to sound, things can get lost in translation. Kraus studies how conditions like concussions and hearing loss can adversely affect auditory processing. Even among healthy brains, we all hear and interpret sounds differently. People have unique “sonic fingerprints” that are relatively stable over time within an individual brain but differ between people. These patterns of sound recognition are apparent when scientists record brain responses to music or other sounds.

“One of the biological measures that we have been using in human and in animal models,” Kraus said, is FFR (frequency following response) to speech. FFR-to-speech can be used to analyze an individual’s auditory processing system. It also allows scientists to convert brain responses back into sound waves. “The sound wave and the brainwave resemble each other, which is just remarkable.”

One of Kraus’s slides. Technology called frequency following response (FFR) can be used to convert brain waves back into original sound (like a song).

This technology helps reveal just how attuned our brains are to sound. When we hear a song, our brain waves respond to everything from the beat to the melody. Those brain waves are so specific to that particular song or sound that when scientists convert the brain waves back into sound, the resulting music is still recognizable.

When scientists try this on people who have experienced a concussion, for instance, the recreated music can sound different or garbled. Experiments that compare healthy and unhealthy brains can help reveal what concussions do to the brain and our ability to interpret sound. But not everything that affects auditory processing is bad.

Musical training is famously good for the brain, and experiments done by Kraus and other scientists support that conclusion. “The musician signature—something that develops over time—” has specific patterns, and it can enhance certain components of auditory processing over time. Making music might also improve language skills. “The music and language signatures really overlap,” Kraus said, “which is why making music is so good for strengthening our sound mind.” Kids who can synchronize to a beat, for example, tend to have better language skills according to some of the experiments Kraus has been involved with.

Musicians are also, on average, better at processing sound in noisy environments. Musicians respond well in quiet and noisy environments. Non-musicians, on the other hand, respond well in quiet environments, but that response “really breaks down” in noisy ones.

Interestingly, “Making music has a lifelong impact. Making music in early life can strengthen the sound mind when one is seventy or eighty years old.”

A slide from Kraus’s presentation. Musicians tend to be better at processing sounds in noisy environments.

Exercise, too, can improve auditory processing. “Elite division 1 athletes have especially quiet brains” with less neural noise. That’s a good thing; it lets incoming information “stand out more.”

In experiments, healthy athletes also have a more consistent response over time across multiple trials, especially women.

These benefits aren’t limited to elite athletes, though. According to Kraus, “Being fit and flexible is one of the best things you can do for your brain,” Kraus said.

Kraus and her team have a regularly updated website about their work. For those who want to learn more about their research, they have a short video about their research approach and an online lecture Kraus gave with the Kennedy Center.

How to Encourage Preschoolers to Be More Fair, According to Science

Exposing young kids to different opinions or asking them to explain their thinking can have surprising benefits, Duke University researchers find.

DURHAM, N.C. — “But that’s not fair!” If you’re a parent or a teacher, you’ve probably heard this countless times.

To most young children, “fair” simply means treating everyone equally. Kids are quick to say they shouldn’t have to go to bed earlier than a sibling, or put up with more chores or homework than a classmate.

But as children get older, they begin to grasp that sometimes, things can be unequal and still be fair — especially when people have different needs, circumstances, or abilities. Up until 8 to 10 years of age, most children aren’t yet capable of such moral subtlety, but a new study shows they can get closer, with help from a surprising source: disagreement.

For preschoolers, a 20-minute conversation with someone who disagrees with them or who asks them to justify their ideas can foster more nuanced moral calculations about what it means to be “fair.”

That’s the key finding from a new Duke University study that examines how children develop their sense of morality.

Many theorists have proposed that a child’s interactions with other people can shape their growing sense of right and wrong. But experiments to pinpoint exactly what kinds of interactions are most helpful have been lacking, said first author Leon Li, who did the research with developmental psychologist Michael Tomasello as part of his PhD in psychology and neuroscience at Duke.

In a study that appeared this summer in the Journal of Experimental Child Psychology, the researchers asked 129 children aged 4 to 5 years to discuss simple moral dilemmas with a puppet and try to make the most fair decision.

In one experiment for example, they asked the children to imagine two boys, one of whom missed breakfast, and decide how to split cookies between them at snack time. In another, the question was whether two girls should get in the same amount of trouble for throwing away someone’s lunch, when one of them mistook it for trash.

No matter what the child decided, afterward the puppet responded by either agreeing or disagreeing, and by either asking the child to explain their reasoning or not. Then the researchers observed how the puppet’s responses affected the child’s thinking in future trials.

They found that children who had previously encountered different points of view, or had to justify their decisions, were more likely to favor the more deserving recipient, rather than fall into “fair must mean equal” thinking.

Li cautions that disagreeing with a child or asking them to justify themselves won’t necessarily make them more honest, or hardworking, or generous.

“Those are other domains of morality, but we only found this in fairness,” Li said. “It’s possible it wouldn’t have an effect with, say, social exclusion” or some other aspect of moral behavior that the team didn’t examine.

But when people ask him, ‘is this how I teach my child to be more virtuous?’ — at least when it comes to fairness — “the answer is yes,” Li said.

The Need for Title IX in STEM

The Panel:

In recognition of the 50th anniversary of Title IX, which was intended to make sex discrimination in education illegal, a panel of Duke women met on Thursday, September 29 to talk about whether Title IX could change STEM, (Science Technology, Engineering and Math). Unfortunately, the answer was not simple.

But just through the sharing of the statistics relevant to this problem, the stories, and their solutions, one could start to understand the depth of this problem. One takeaway was that all women in STEM, whether they be student, professor, or director, have faced gender discrimination.

Down to the Statistics:

Dr. Sherryl Broverman, a Duke professor of the practice in biology and global health, gave the audience an overview. Of all of Duke’s regular ranked, tenured-track faculty, only 30% are women. In contrast, women make up 60% of the non-tenure track faculty. Dr. Broverman said men are promoted in Duke at a higher frequency. This is especially seen with the associate professor title because, on average, men are associate professors for 4 to 5 years; whereas women are associate professors for up to 9 years.

To give an example, senior Nasya Bernard-Lucien, a student panelist who studied Biomedical Engineering and then Neuroscience informed me that she has had a total of two women professors in her entire STEM career. This is a common pattern here at Duke because taking a STEM class that has a woman professor is as rare as finding a non-stressed Duke student.

The Beginning of a Girl’s Career in STEM

This disproportionate demographic of women professors in STEM is not a new occurrence with Duke or the rest of the world because the disproportion of women in STEM can be seen as early as middle school. Two of the student panelists noted that during their middle school career, they were not chosen to join an honors STEM program and had to push their school’s administration when they asked to take more advanced STEM classes.

Dr. Kisha Daniels, an associate professor of the practice in education said on a faculty panel that one of her daughters was asked by her male peers, “what are you doing here?” when she attended her middle school’s honors math class. Gender discrimination in STEM begins in early childhood, and it extends its reach as long as women continue to be in a STEM field, and that is particularly evident here at Duke.

Dr. Sherryl Broverman

The last panel of the Title IX @ 50 event was the student panel which consisted of undergraduate and graduate students. Even though they were all from different backgrounds, all acknowledged the gender disparity within STEM classes.

Student Bentley Choi said she was introduced to this experience of gender discrimination when she first arrived at Duke from South Korea. She noted how she was uncomfortable and how it was hard to ask for help while being one of the few women in her physics class. One would have hoped that Duke would provide a more welcoming environment to her, but that is not the case, and it is also not an isolated incident. Across the panel, all of the women have experienced discomfort in their STEM classes due to being one of the few girls in there.

The Future of Title IX

How can Title IX change these issues? Right now, Title IX and STEM are not as connected as they need to be; in fact, Title IX, in the past, has been used to attack programs created to remedy the gender disparity in STEM. So, before Title IX can change STEM, it needs to change itself.

Title IX needs to address that this problem is a systemic issue and not a standalone occurrence. However, for this change to happen, Dr. Whitney McCoy, a research scientist in Child and Family Policy, said it perfectly, “we need people of all backgrounds to voice the same opinion to create policy change.”

So, talk to your peers about this issue because the more people who understand this situation, the chances of creating a change increases. The last thing that needs to occur is that 50 years in the future, there will be similar panels like this one that talk about this very issue, and there are no panels that talk about how we, in the present, fixed it.
