To Make Science Engaging, We Need a Sesame Street for Adults
A new kind of television series could establish the baseline narratives for novel science like gene editing, quantum computing, or artificial intelligence.
This article is part of the magazine, "The Future of Science In America: The Election Issue," co-published by LeapsMag, the Aspen Institute Science & Society Program, and GOOD.
In the mid-1960s, a documentary producer in New York City wondered if the addictive jingles, clever visuals, slogans, and repetition of television ads—the ones that were captivating young children of the time—could be harnessed for good. Over the course of three months, she interviewed educators, psychologists, and artists, and the result was a bonanza of ideas.
Perhaps a new TV show could teach children letters and numbers in short animated sequences? Perhaps adults and children could read together with puppets providing comic relief and prompting interaction from the audience? And because it would be broadcast through a device already in almost every home, perhaps this show could reach across socioeconomic divides and close an early education gap?
Soon after Joan Ganz Cooney shared her landmark report, "The Potential Uses of Television in Preschool Education," in 1966, she was prototyping show ideas, attracting funding from The Carnegie Corporation, The Ford Foundation, and The Corporation for Public Broadcasting, and co-founding the Children's Television Workshop with psychologist Lloyd Morrisett. And then, on November 10, 1969, informal learning was transformed forever with the premiere of Sesame Street on public television.
For its first season, Sesame Street won three Emmy Awards and a Peabody Award. Its star, Big Bird, landed on the cover of Time Magazine, which called the show "TV's gift to children." Fifty years later, it's hard to imagine an approach to informal preschool learning that isn't Sesame Street.
And that approach can be boiled down to one word: Entertainment.
Despite decades of evidence from Sesame Street—one of the most studied television shows of all time—and more research from social science, psychology, and media communications, we haven't yet taken Ganz Cooney's concepts to heart in educating adults. Adults have news programs and documentaries and educational YouTube channels, but no Sesame Street. So why don't we? Here's how we can design a new kind of television to make science engaging and accessible for a public that is all too often intimidated by it.
We have to start from the realization that America is a nation of high-school graduates. By the end of high school, students have decided to abandon science because they think it's too difficult, and as a nation, we've made it acceptable for any one of us to say "I'm not good at science" and offload thinking to the ones who might be. So, is it surprising that a large number of Americans are likely to believe in conspiracy theories like the 25% that believe the release of COVID-19 was planned, the one in ten who believe the Moon landing was a hoax, or the 30–40% that think the condensation trails of planes are actually nefarious chemtrails? If we're meeting people where they are, the aim can't be to get the audience from an A to an A+, but from an F to a D, and without judgment of where they are starting from.
There's also a natural compulsion for a well-meaning educator to fill a literacy gap with a barrage of information, but this is what I call "factsplaining," and we know it doesn't work. And worse, it can backfire. In one study from 2014, parents were provided with factual information about vaccine safety, and it was the group that was already the most averse to vaccines that uniquely became even more averse.
Why? Our social identities and cognitive biases are stubborn gatekeepers when it comes to processing new information. We filter ideas through pre-existing beliefs—our values, our religions, our political ideologies. Incongruent ideas are rejected. Congruent ideas, no matter how absurd, are allowed through. We hear what we want to hear, and then our brains justify the input by creating narratives that preserve our identities. Even when we have all the facts, we can use them to support any worldview.
But social science has revealed many mechanisms for hijacking these processes through narrative storytelling, and this can form the foundation of a new kind of educational television.
Could new television series establish the baseline narratives for novel science like gene editing, quantum computing, or artificial intelligence?
As media creators, we can reject factsplaining and instead construct entertaining narratives that disrupt cognitive processes. Two-decade-old research tells us when people are immersed in entertaining fiction narratives, they loosen their defenses, opening a path for new information, editing attitudes, and inspiring new behavior. Where news about hot-button issues like climate change or vaccination might trigger resistance or a backfire effect, fiction can be crafted to be absorbing and, as a result, persuasive.
But the narratives can't be stuffed with information. They must be simplified. If this feels like the opposite of what an educator should be doing, it is possible to reduce the complexity of information, without oversimplification, through "exemplification," a framing device to tell the stories of individuals in specific circumstances that can speak to the greater issue without needing to explain it all. It's a technique you've seen used in biopics. The Discovery Channel true-crime miniseries Manhunt: Unabomber does many things well from a science storytelling perspective, including exemplifying the virtues of the scientific method through a character who argues for a new field of science, forensic linguistics, to catch one of the most notorious domestic terrorists in U.S. history.
We must also appeal to the audience's curiosity. We know curiosity is such a strong driver of human behavior that it can even counteract the biases put up by one's political ideology around subjects like climate change. If we treat science information like a product—and we should—advertising research tells us we can maximize curiosity though a Goldilocks effect. If the information is too complex, your show might as well be a PowerPoint presentation. If it's too simple, it's Sesame Street. There's a sweet spot for creating intrigue about new information when there's a moderate cognitive gap.
The science of "identification" tells us that the more the main character is endearing to a viewer, the more likely the viewer will adopt the character's worldview and journey of change. This insight further provides incentives to craft characters reflective of our audiences. If we accept our biases for what they are, we can understand why the messenger becomes more important than the message, because, without an appropriate messenger, the message becomes faint and ineffective. And research confirms that the stereotype-busting doctor-skeptic Dana Scully of The X-Files, a popular science-fiction series, was an inspiration for a generation of women who pursued science careers.
With these directions, we can start making a new kind of television. But is television itself still the right delivery medium? Americans do spend six hours per day—a quarter of their lives—watching video. And even with the rise of social media and apps, science-themed television shows remain popular, with four out of five adults reporting that they watch shows about science at least sometimes. CBS's The Big Bang Theory was the most-watched show on television in the 2017–2018 season, and Cartoon Network's Rick & Morty is the most popular comedy series among millennials. And medical and forensic dramas continue to be broadcast staples. So yes, it's as true today as it was in the 1980s when George Gerbner, the "cultivation theory" researcher who studied the long-term impacts of television images, wrote, "a single episode on primetime television can reach more people than all science and technology promotional efforts put together."
We know from cultivation theory that media images can shape our views of scientists. Quick, picture a scientist! Was it an old, white man with wild hair in a lab coat? If most Americans don't encounter research science firsthand, it's media that dictates how we perceive science and scientists. Characters like Sheldon Cooper and Rick Sanchez become the model. But we can correct that by representing professionals more accurately on-screen and writing characters more like Dana Scully.
Could new television series establish the baseline narratives for novel science like gene editing, quantum computing, or artificial intelligence? Or could new series counter the misinfodemics surrounding COVID-19 and vaccines through more compelling, corrective narratives? Social science has given us a blueprint suggesting they could. Binge-watching a show like the surreal NBC sitcom The Good Place doesn't replace a Ph.D. in philosophy, but its use of humor plants the seed of continued interest in a new subject. The goal of persuasive entertainment isn't to replace formal education, but it can inspire, shift attitudes, increase confidence in the knowledge of complex issues, and otherwise prime viewers for continued learning.

Podcast: A Nasal Spray COVID Booster Shot, With Dr. Akiko Iwasaki
Dr. Akiko Iwasaki, an immunologist at Yale, is working on creating a nasal spray booster after the primary mRNA shots.
The "Making Sense of Science" podcast features interviews with leading medical and scientific experts about the latest developments and the big ethical and societal questions they raise. This monthly podcast is hosted by journalist Kira Peikoff, founding editor of the award-winning science outlet Leaps.org.
Real-world data shows that protection against Covid-19 infection wanes a few months after two or three shots of mRNA vaccines (while protection against severe disease remains high). But what if there was another kind of booster that could shore up the immune response in your nose, the "door" to your body? Like bouncers at a club, a better prepared nasal defense system could stop the virus in its tracks -- mitigating illnesses as well as community spread. Dr. Akiko Iwasaki, an immunologist at Yale, is working on such a booster, with fantastic results recently reported in mice. In this episode, she shares the details of this important work.

Technology is Redefining the Age of 'Older Mothers'
Scientists are working on technologies that would enable more 70-year-old women to have babies.
In October 2021, a woman from Gujarat, India, stunned the world when it was revealed she had her first child through in vitro fertilization (IVF) at age 70. She had actually been preceded by a compatriot of hers who, two years before, gave birth to twins at the age of 73, again with the help of IVF treatment. The oldest known mother to conceive naturally lived in the UK; in 1997, Dawn Brooke conceived a son at age 59.
These women may seem extreme outliers, almost freaks of nature; in the US, for example, the average age of first-time mothers is 26. A few decades from now, though, the sight of 70-year-old first-time mothers may not even raise eyebrows, say futurists.
“We could absolutely have more 70-year-old mothers because we are learning how to regulate the aging process better,” says Andrew Hessel, a microbiologist and geneticist, who cowrote "The Genesis Machine," a book about “rewriting life in the age of synthetic biology,” with Amy Webb, the futurist who recently wondered why 70-year-old women shouldn’t give birth.
Technically, we're already doing this, says Hessel, pointing to a technique known as in vitro gametogenesis (IVG). IVG refers to turning adult cells into sperm or egg cells. “You can think of it as the upgrade to IVF,” Hessel says. These vanguard stem cell research technologies can take even skin cells and turn them into induced pluripotent stem cells (iPSCs), which are basically master cells capable of maturing into any human cell, be it kidney cells, liver cells, brain cells or gametes, aka eggs and sperm, says Henry T. “Hank” Greely, a Stanford law professor who specializes in ethical, legal, and social issues in biosciences.
Mothers over 70 will be a minor blip, statistically speaking, Greely predicts.
In 2016, Greely wrote "The End of Sex," a book in which he described the science of making gametes out of iPSCs in detail. Greely says science will indeed enable us to see 70-year-old new mums fraternize with mothers several decades younger at kindergartens in the (not far) future. And it won’t be that big of a deal.
“An awful lot of children all around the world have been raised by grandmothers for millennia. To have 70-year-olds and 30-year-olds mingling in maternal roles is not new,” he says. That said, he doubts that many women will want to have a baby in the eighth decade of their life, even if science allows it. “Having a baby and raising a child is hard work. Even if 1% of all mothers are over 65, they aren’t going to change the world,” Greely says. Mothers over 70 will be a minor blip, statistically speaking, he predicts. But one thing is certain: the technology is here.
And more technologies for the same purpose could be on the way. In March 2021, researchers from Monash University in Melbourne, Australia, published research in Nature, where they successfully reprogrammed skin cells into a three-dimensional cellular structure that was morphologically and molecularly similar to a human embryo–the iBlastoid. In compliance with Australian law and international guidelines referencing the “primitive streak rule," which bans the use of embryos older than 14 days in scientific research, Monash scientists stopped growing their iBlastoids in vitro on day 11.
“The research was both cutting-edge and controversial, because it essentially created a new human life, not for the purpose of a patient who's wanting to conceive, but for basic research,” says Lindsay Wu, a senior lecturer in the School of Medical Sciences at the University of New South Wales (UNSW), in Kensington, Australia. If you really want to make sure what you are breeding is an embryo, you need to let it develop into a viable baby. “This is the real proof in the pudding,'' says Wu, who runs UNSW’s Laboratory for Ageing Research. Then you get to a stage where you decide for ethical purposes you have to abort it. “Fiddling here a bit too much?” he asks. Wu believes there are other approaches to tackling declining fertility due to older age that are less morally troubling.
He is actually working on them. Why would it be that women, who are at peak physical health in almost every other regard, in their mid- to late- thirties, have problems conceiving, asked Wu and his team in a research paper published in 2020 in Cell Reports. The simple answer is the egg cell. An average girl in puberty has between 300,000 and 400,000 eggs, while at around age 37, the same woman has only 25,000 eggs left. Things only go downhill from there. So, what torments the egg cells?
The UNSW team found that the levels of key molecules called NAD+ precursors, which are essential to the metabolism and genome stability of egg cells, decline with age. The team proceeded to add these vitamin-like substances back into the drinking water of reproductively aged, infertile lab mice, which then had babies.
“It's an important proof of concept,” says Wu. He is investigating how safe it is to replicate the experiment with humans in two ongoing studies. The ultimate goal is to restore the quality of egg cells that are left in patients in their late 30s and early- to mid-40s, says Wu. He sees the goal of getting pregnant for this age group as less ethically troubling, compared to 70-year-olds.
But what is ethical, anyway? “It is a tricky word,” says Hessel. He differentiates between ethics, which represent a personal position and may, thus, be more transient, and morality, longer lasting principles embraced across society such as, “Thou shalt not kill.” Unprecedented advances often bring out fear and antagonism until time passes and they just become…ordinary. When IVF pioneer Landrum Shettles tried to perform IVF in 1973, the chairman of Columbia’s College of Physicians and Surgeons interdicted the procedure at the last moment. Almost all countries in the world have IVF clinics today, and the global IVF services market is clearly a growth industry.
Besides, you don’t have a baby at 70 by accident: you really want it, Greely and Hessel agree. And by that age, mothers may be wiser and more financially secure, Hessel says (though he is quick to add that even the pregnancy of his own wife, who had her child at 40, was a high-risk one).
As a research question, figuring out whether older mothers are better than younger ones and vice-versa entails too many confounding variables, says Greely. And why should we focus on who’s the better mother anyway? “We've had 70-year-old and 80-year-old fathers forever–why should people have that much trouble getting used to mothers doing the same?” Greely wonders. For some women having a child at an old(er) age would be comforting; maybe that’s what matters.
And the technology to enable older women to have children is already here or coming very soon. That, perhaps, matters even more. Researchers have already created mice–and their offspring–entirely from scratch in the lab. “Doing this to produce human eggs is similar," says Hessel. "It is harder to collect tissues, and the inducing cocktails are different, but steady advances are being made." He predicts that the demand for fertility treatments will keep financing research and development in the area. He says that big leaps will be made if ethical concerns don’t block them: it is not far-fetched to believe that the first baby produced from lab-grown eggs will be born within the next decade.
In an op-ed in 2020 with Stat, Greely argued that we’ve already overcome the technical barrier for human cloning, but no one's really talking about it. Likewise, scientists are also working on enabling 70-year-old women to have babies, says Hessel, but most commentators are keeping really quiet about it. At least so far.
