To Make Science Engaging, We Need a Sesame Street for Adults
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.

How Will the New Strains of COVID-19 Affect Our Vaccination Plans?
When the world's first Covid-19 vaccine received regulatory approval in November, it appeared that the end of the pandemic might be near. As one by one, the Pfizer/BioNTech, Moderna, AstraZeneca, and Sputnik V vaccines reported successful Phase III results, the prospect of life without lockdowns and restrictions seemed a tantalizing possibility.
But for scientists with many years' worth of experience in studying how viruses adapt over time, it remained clear that the fight against the SARS-CoV-2 virus was far from over. "The more virus circulates, the more it is likely that mutations occur," said Professor Beate Kampmann, director of the Vaccine Centre at the London School of Hygiene & Tropical Medicine. "It is inevitable that new variants will emerge."
Since the start of the pandemic, dozens of new variants of SARS-CoV-2 – containing different mutations in the viral genome sequence - have appeared as it copies itself while spreading through the human population. The majority of these mutations are inconsequential, but in recent months, some mutations have emerged in the receptor binding domain of the virus's spike protein, increasing how tightly it binds to human cells. These mutations appear to make some new strains up to 70 percent more transmissible, though estimates vary and more lab experiments are needed. Such new strains include the B.1.1.7 variant - currently the dominant strain in the UK – and the 501Y.V2 variant, which was first found in South Africa.
"I'm quite optimistic that even with these mutations, immunity is not going to suddenly fail on us."
Because so many more people are becoming infected with the SARS-CoV-2 virus as a result, vaccinologists point out that these new strains will prolong the pandemic.
"It may take longer to reach vaccine-induced herd immunity," says Deborah Fuller, professor of microbiology at the University of Washington School of Medicine. "With a more transmissible variant taking over, an even larger percentage of the population will need to get vaccinated before we can shut this pandemic down."
That is, of course, as long as the vaccinations are still highly protective. The South African variant, in particular, contains a mutation called E484K that is raising alarms among scientists. Emerging evidence indicates that this mutation allows the virus to escape from some people's immune responses, and thus could potentially weaken the effectiveness of current vaccines.
What We Know So Far
Over the past few weeks, manufacturers of the approved Covid-19 vaccines have been racing to conduct experiments, assessing whether their jabs still work well against the new variants. This process involves taking blood samples from people who have already been vaccinated and assessing whether the antibodies generated by those people can neutralize the new strains in a test tube.
Pfizer has just released results from the first of these studies, declaring that their vaccine was found to still be effective at neutralizing strains of the virus containing the N501Y mutation of the spike protein, one of the mutations present within both the UK and South African variants.
However, the study did not look at the full set of mutations contained within either of these variants. Earlier this week, academics at the Fred Hutchinson Cancer Research Center in Seattle suggested that the E484K spike protein mutation could be most problematic, publishing a study which showed that the efficacy of neutralizing antibodies against this region dropped by more than ten-fold because of the mutation.
Thankfully, this development is not expected to make vaccines useless. One of the Fred Hutch researchers, Jesse Bloom, told STAT News that he did not expect this mutation to seriously reduce vaccine efficacy, and that more harmful mutations would need to accrue over time to pose a very significant threat to vaccinations.
"I'm quite optimistic that even with these mutations, immunity is not going to suddenly fail on us," Bloom told STAT. "It might be gradually eroded, but it's not going to fail on us, at least in the short term."
While further vaccine efficacy data will emerge in the coming weeks, other vaccinologists are keen to stress this same point: At most, there will be a marginal drop in efficacy against the new variants.
"Each vaccine induces what we call polyclonal antibodies targeting multiple parts of the spike protein," said Fuller. "So if one antibody target mutates, there are other antibody targets on the spike protein that could still neutralize the virus. The vaccine platforms also induce T-cell responses that could provide a second line of defense. If some virus gets past antibodies, T-cell responses can find and eliminate infected cells before the virus does too much damage."
She estimates that if vaccine efficacy decreases, for example from 95% to 85%, against one of the new variants, the main implications will be that some individuals who might otherwise have become severely ill, may still experience mild or moderate symptoms from an infection -- but crucially, they will not end up in intensive care.
"Plug and Play" Vaccine Platforms
One of the advantages of the technologies which have been pioneered to create the Covid-19 vaccines is that they are relatively straightforward to update with a new viral sequence. The mRNA technology used in the Pfizer/BioNTech and Moderna vaccines, and the adenovirus vectors used in the Astra Zeneca and Sputnik V vaccines, are known as 'plug and play' platforms, meaning that a new form of the vaccine can be rapidly generated against any emerging variant.
"With a rapid pipeline for manufacture established, these new vaccine technologies could enable production and distribution within 1-3 months of a new variant emerging."
While the technology for the seasonal influenza vaccines is relatively inefficient, requiring scientists to grow and cultivate the new strain in the lab before vaccines can be produced - a process that takes nine months - mRNA and adenovirus-based vaccines can be updated within a matter of weeks. According to BioNTech CEO Uğur Şahin, a new version of their vaccine could be produced in six weeks.
"With a rapid pipeline for manufacture established, these new vaccine technologies could enable production and distribution within 1-3 months of a new variant emerging," says Fuller.
Fuller predicts that more new variants of the virus are almost certain to emerge within the coming months and years, potentially requiring the public to receive booster shots. This means there is one key advantage the mRNA-based vaccines have over the adenovirus technologies. mRNA vaccines only express the spike protein, while the AstraZeneca and Sputnik V vaccines use adenoviruses - common viruses most of us are exposed to - as a delivery mechanism for genes from the SARS-CoV-2 virus.
"For the adenovirus vaccines, our bodies make immune responses against both SARS-CoV-2 and the adenovirus backbone of the vaccine," says Fuller. "That means if you update the adenovirus-based vaccine with the new variant and then try to boost people, they may respond less well to the new vaccine, because they already have antibodies against the adenovirus that could block the vaccine from working. This makes mRNA vaccines more amenable to repeated use."
Regulatory Unknowns
One of the key questions remains whether regulators would require new versions of the vaccine to go through clinical trials, a hurdle which would slow down the response to emerging strains, or whether the seasonal influenza paradigm will be followed, whereby a new form of the vaccine can be released without further clinical testing.
Regulators are currently remaining tight-lipped on which process they will choose to follow, until there is more information on how vaccines respond against the new variants. "Only when such information becomes available can we start the scientific evaluation of what data would be needed to support such a change and assess what regulatory procedure would be required for that," said Rebecca Harding, communications officer for the European Medicines Agency.
The Food and Drug Administration (FDA) did not respond to requests for comment before press time.
While vaccinologists feel it is unlikely that a new complete Phase III trial would be required, some believe that because these are new technologies, regulators may well demand further safety data before approving an updated version of the vaccine.
"I would hope if we ever have to update the current vaccines, regulatory authorities will treat it like influenza," said Drew Weissman, professor of medicine at the University of Pennsylvania, who was involved in developing the mRNA technology behind the Pfizer/BioNTech and Moderna vaccines. "I would guess, at worst, they may want a new Phase 1 or 1 and 2 clinical trials."
Others suggest that rather than new trials, some bridging experiments may suffice to demonstrate that the levels of neutralizing antibodies induced by the new form of the vaccine are comparable to the previous one. "Vaccines have previously been licensed by this kind of immunogenicity data only, for example meningitis vaccines," said Kampmann.
While further mutations and strains of SARS-CoV-2 are inevitable, some scientists are concerned that the vaccine rollout strategy being employed in some countries -- of distributing a first shot to as many people as possible, and potentially delaying second shots as a result -- could encourage more new variants to emerge. Just today, the Biden administration announced its intention to release nearly all vaccine doses on hand right away, without keeping a reserve for second shots. This plan risks relying on vaccine manufacturing to ramp up quickly to keep pace if people are to receive their second shots at the right intervals.
"I am not very happy about this change as it could lead to a large number of people out there with partial immunity and this could select new mutations, and escalate the potential problem of vaccine escape."
The Biden administration's shift appears to conflict with the FDA's recent position that second doses should be given on a strict schedule, without any departure from the three- and four-week intervals established in clinical trials. Two top FDA officials said in a statement that changing the dosing schedule "is premature and not rooted solidly in the available evidence. Without appropriate data supporting such changes in vaccine administration, we run a significant risk of placing public health at risk, undermining the historic vaccination efforts to protect the population from COVID-19."
"I understand the argument of trying to get at least partial protection to as many people as possible, but I am concerned about the increased interval between the doses that is now being proposed," said Kampmann. "I am not very happy about this change as it could lead to a large number of people out there with partial immunity and this could select new mutations, and escalate the potential problem of vaccine escape."
But it's worth emphasizing that the virus is unlikely for now to accumulate enough harmful mutations to render the current vaccines completely ineffective.
"It will be very hard for the virus to evolve to completely evade the antibody responses the vaccines induce," said Fuller. "The parts of the virus that are targeted by vaccine-induced antibodies are essential for the virus to infect our cells. If the virus tries to mutate these parts to evade antibodies, then it could compromise its own fitness or even abort its ability to infect. To be sure, the virus is developing these mutations, but we just don't see these variants emerge because they die out."
COVID Vaccines Put Anti-Science Activists to Shame
It turns out that, despite the destruction and heartbreak caused by the COVID pandemic, there is a silver lining: Scientists from academia, government, and industry worked together and, using the tools of biotechnology, created multiple vaccines that surely will put an end to the worst of the pandemic sometime in 2021. In short, they proved that science works, particularly that which comes from industry. Though politicians and the public love to hate Big Ag and Big Pharma, everybody comes begging for help when the going gets tough.
The change in public attitude is tangible. A headline in the Financial Times declared, "Covid vaccines offer Big Pharma a chance of rehabilitation." In its analysis, the FT says that the pharmaceutical industry is widely reviled because of the high prices it charges for its drugs, among other things, but the speed with which the industry developed COVID vaccines may allow for its reputation to be refurbished.
The Media's Role in Promoting Anti-Biotech Activism
Of course, the media is partly to blame for the pharmaceutical industry's dismal reputation in the first place because of journalists' penchant for oversimplifying complicated stories and pinning blame on an easy scapegoat. While the pharmaceutical industry is far from angelic and places a hefty price tag on its products in the U.S., often gone unmentioned is the fact that high drug prices are the result of multiple factors, including lack of competition (even among generic drugs), foreign price controls that allow citizens of other countries to "free load" off of American consumers, and a deliberately opaque drug supply chain (that involves not only profit-maximizing pharmaceutical manufacturers but "middlemen" like distributors). But why delve into such nuance when it's easier to point to villains like Martin Shkreli?
Big Ag has been subjected to identical mistreatment by the media, with outlets such as the New York Times among the biggest offenders. One article it published compared pesticides to "Nazi-made sarin gas," and another spread misinformation about a high-profile biotech scientist. The website Undark, whose stated mission is "true journalistic coverage of the sciences," once published an opinion piece written by a person who works for an anti-GMO organization and another criticizing Monsanto for its reasonable efforts to defend itself from disinformation. These aren't cherry-picked examples. Overall, the media clearly has taken sides: Science is great, unless it's science from industry.
If the scientific community can use the powerful techniques of biotechnology to cure a previously unknown infectious disease in less than a year, then why shouldn't it be able to cure genetic diseases in humans?
Now, the very same media – which has portrayed the pharmaceutical and biotech industries in the worst possible light, often for political or ideological reasons – is wondering why so many Americans are reluctant to get a COVID vaccine. Perhaps their reportage has something to do with it.
Tech Strikes Back
For years, the agricultural, pharmaceutical, and biotech industries fought back, but to no avail. GMOs are feared, pharma is hated, and biotech is misunderstood. Regulatory red tape abounds. But that may be all about to change, not because of a clever PR campaign, but thanks to the successful coronavirus vaccines produced by the pharma/biotech industry.
All of the major vaccines were created using biotechnology, broadly defined as the use of living systems and organisms to develop products intended to improve human life or the planet. The Pfizer/BioNTech and Moderna vaccines rely on mRNA (messenger RNA), which is essentially a molecular "photocopy" of the more familiar genetic material DNA. The mRNA molecules were tweaked using biotech and then shown to be 95% effective at preventing COVID in human volunteers. The AstraZeneca/Oxford vaccine is based on an older technology that genetically modifies a harmless virus to resemble an immunological target, in this case, SARS-CoV-2. Their vaccine is 62% to 90% effective.
Even better, the pharma/biotech industry showed that it can work hand-in-hand with the government, for instance the FDA, to produce vaccines in record-breaking time. Operation Warp Speed provided some financing to facilitate this process. History will look back at this endeavor and likely conclude that the unprecedented level of cooperation to develop a vaccine in less than 12 months was one of the greatest triumphs in public health history. (The bungled slow rollout is another story.)
Perhaps the most important lesson that society will learn is that the scientific method works.
The pharma/biotech industry has thus gained tremendous momentum. For the first time it seems, those who are opposed to scientific progress and biotechnology are on the defensive. If the scientific community can use the powerful techniques of biotechnology to cure a previously unknown infectious disease in less than a year, then why shouldn't it be able to cure genetic diseases in humans? Or create genetically modified crops that are resistant to insects and drought? Or use genetically modified mosquitoes to help fight against killer diseases like malaria? The arguments against biotechnology have been made exponentially weaker by the success of the coronavirus vaccine.
Perhaps the most important lesson that society will learn is that the scientific method works. We observed (by collecting samples of an unknown virus and sequencing its genome), hypothesized (by predicting which parts of the virus would trigger an immune response), experimented (by recruiting tens of thousands of volunteers into clinical trials), and concluded (that the vaccines worked). It was a thing of pure beauty.
Thanks to all the players involved – from Big Government to Big Pharma – we are beginning the process of being rescued from a modern-day plague. Let us hope that this scientific success also deals a fatal blow to the forces of ignorance that have held back technological progress for decades.
