“Vaccinate” Yourself Against Fake News by Playing a Fascinating Online Game
There's no shortage of fake news going around the internet these days, but how do we become more aware as consumers of what's real and what's not?
"We are hoping to create what you might call a general 'vaccine' against fake news, rather than trying to counter each specific conspiracy or falsehood."
Researchers at the University of Cambridge may have answered just that by developing an online game designed to expose and educate participants to the tactics used by those spreading false information.
"We wanted to see if we could preemptively debunk, or 'pre-bunk', fake news by exposing people to a weak dose of the methods used to create and spread disinformation, so they have a better understanding of how they might be deceived," Dr Sander van der Linden, Director of the Cambridge Social Decision-Making Lab, said in a statement.
"This is a version of what psychologists call 'inoculation theory', with our game working like a psychological vaccination."
In February 2018, van der Linden and his coauthor, Jon Roozenbeek, helped launch the browser game, "Bad News," where players take on the role of "Disinformation and Fake News Tycoon."
They can manipulate news and social media within the game by several different methods, including deploying twitter-bots, photo-shopping evidence, creating fake accounts, and inciting conspiracy theories with the goal of attracting followers and maintaining a "credibility score" for persuasiveness.
In order to gauge the game's effectiveness, players were asked to rate the reliability of a number of real and fake news headlines and tweets both before and after playing. The data from 15,000 players was evaluated, with the results published June 25 in the journal Palgrave Communications.
The results concluded that "the perceived reliability of fake news before playing the game had reduced by an average of 21% after completing it. Yet the game made no difference to how users ranked real news."
Just 15 minutes of playing the game can have a moderate effect on people, which could play a major role on a larger scale.
Additionally, participants who "registered as most susceptible to fake news headlines at the outset benefited most from the 'inoculation,'" according to the study.
Just 15 minutes of playing the game can have a moderate effect on people, which could play a major role on a larger scale when it comes to "building a societal resistance to fake news," according to Dr. van der Linden.
"Research suggests that fake news spreads faster and deeper than the truth, so combating disinformation after-the-fact can be like fighting a losing battle," he said.
"We are hoping to create what you might call a general 'vaccine' against fake news, rather than trying to counter each specific conspiracy or falsehood," Roozenbeek added.
Van der Linden and Roozenbeek's work is an early example of the potential methods to protect people against deception by training them to be more attuned to the methods used to distribute fake news.
"I hope that the positive results give further credence to the new science of prebunking rather than only thinking about traditional debunking. On a larger level, I also hope the game and results inspire a new kind of behavioral science research where we actively engage with people and apply insights from psychological science in the public interest," van der Linden told leapsmag.
"I like the idea that the end result of a scientific theory is a real-world partnership and practical tool that organizations and people can use to guard themselves against online manipulation techniques in a novel and hopefully fun and engaging manner."
Ready to be "inoculated" against fake news? Then play the game for yourself.
In 1962, the world was a remarkably different place: Neil Armstrong had yet to take his first steps on the lunar surface, John F. Kennedy was serving as president of the United States, and the Beatles were still a few years away from superstardom, having just recorded their first single.
The word “measles” was also a household name. Measles, which still exists in parts of the world today, is a highly contagious viral infection that typically causes fever, cough, muscle pain, fatigue, and a distinctive red rash. Measles was so pervasive around the world in 1962 that most children had gotten sick with it before the age of fifteen—but even though it was common, it was far from harmless. Measles killed around 400 to 500 people per year in the United States, and approximately 2.6 million people each year worldwide. Countless others suffered severe complications from measles, such as permanent blindness.
Tragedy hits home

That year, British author Roald Dahl was beginning to make a name for himself, having just published his best-selling book James and the Giant Peach. Dahl, who would go on to write some of the most well-loved children’s books of the century, lived in southern England with his wife and three children. One day, Dahl and his wife, actress Patricia Neal, received word that there was an outbreak of measles at his daughters’ school.
While some parents quarantined their children, many others also considered measles a harmless childhood disease. Neal later recalled in her autobiography that a family member had advised her to “let the girls get measles,” thinking it would strengthen their immune systems and be “good for them.” Reluctantly, Dahl and Neal let their two school-aged children, Olivia and Chantal, continue school. Olivia, then aged seven, fell sick with the measles not long after that.
Neither Dahl nor Neal were terribly concerned about Olivia’s infection. Dahl would write later that it seemed to be taking its “usual course,” and the two would read and spend time together while Olivia rested. After a few days of fever and fatigue, Dahl wrote, Olivia seemed like she was “well on the road to recovery.”
But one afternoon, as the two sat on Olivia’s bed making animals out of pipe cleaners, Dahl noticed that Olivia’s “fingers and her mind were not working together.” When Dahl asked how she was feeling, Olivia replied, “I feel all sleepy.”
Within an hour, Dahl wrote, Olivia was unconscious. Within 12 hours, she was dead.
Olivia died of measles encephalitis, an inflammation of the brain caused by an infection. Approximately 1 in 1,000 people infected with measles develop encephalitis, and of those who develop it, between 10 and 20 percent will die.
Dahl was overcome with grief and wracked with guilt for being unable to prevent his daughter’s death. Mourning, Dahl threw himself into his writing and, in his spare time, spent hours lovingly constructing a rock garden on Olivia’s grave in a local churchyard.
After Olivia’s death, Dahl wrote sixteen novels and several collections of short stories, including Matilda, Fantastic Mr. Fox, and Willy Wonka and the Chocolate Factory, which garnered him worldwide acclaim. His most influential piece of writing, however, wasn’t written until 1986.
A father's plea
Roald Dahl and the open letter he wrote in 1986, encouraging parents to vaccinate their children against measles.
By 1986, measles was no longer the global health threat that it had been in the 1960s, thanks to a measles vaccine that became available just one year after Olivia had died. Still, in the United Kingdom alone, approximately 80,000 people every year were infected with measles. This bothered Dahl, especially since measles rates in the United States had dropped by 98 percent compared to pre-vaccine years. “Why do we have so much measles in Britain when the Americans have virtually gotten rid of it?,” Dahl was reported to have said.
So Dahl set out to prevent a tragedy like Olivia’s from happening again. With encouragement from several prominent public health activists, Dahl wrote an open letter addressed to parents in the UK. The letter recounted his daughter’s death from encephalitis and begged parents to protect their own children from measles:
“...there is today something that parents can do to make sure that this sort of tragedy does not happen to a child of theirs. They can insist that their child is immunised [sic] against measles. I was unable to do that for Olivia in 1962 because in those days a reliable measles vaccine had not been discovered. Today a good and safe vaccine is available to every family and all you have to do is to ask your doctor to administer it.”
Dahl went on to say that although many parents still viewed measles as a harmless illness, he knew from experience that it was not. Measles was capable of causing disability and death, Dahl wrote, whereas a child had a better chance of “choking on a chocolate bar” than developing any serious complication from the vaccine. Dahl ended his letter by saying how happy he knew Olivia would be “if only she could know that her death had helped to save a good deal of illness and death among other children.”
Dahl’s letter was published in early 1986 and distributed to local healthcare workers, schools, and to parents of children who were particularly at risk. As the letter circulated, vaccination rates continued to climb year after year.
Thirty-one years after Dahl’s letter was published, and 55 years after Olivia’s death, the World Health Organization declared in 2017 that measles had officially been eradicated for the first time in the UK thanks to high rates of vaccination.
A small step back
As vaccination rates decline, measles is now making a strong comeback in the United States and elsewhere.
Today, vaccination rates for the measles are in decline, and countries like the UK and the US, who had once eradicated measles completely, are now seeing a comeback. The Centers for Disease Control and Prevention (CDC) recently reported that between December 1, 2023 and January 23, 2024, 23 cases of measles had been confirmed across multiple states. The majority of these cases, they reported, were among children and adolescents who had traveled internationally and had not yet been vaccinated even though they were eligible to do so.
Roald Dahl passed away in 1990, but fortunately, his writing continues to live on. While readers can explore fantastical worlds through his novels and short stories, they can also look back to a reality when tragic deaths like Olivia’s happened far too often. The difference is that today, thanks to modern science, we now have the tools to stop them.

On today’s episode of Making Sense of Science, I’m honored to be joined by Dr. Paul Song, a physician, oncologist, progressive activist and biotech chief medical officer. Through his company, NKGen Biotech, Dr. Song is leveraging the power of patients’ own immune systems by supercharging the body’s natural killer cells to make new treatments for Alzheimer’s and cancer.
Whereas other treatments for Alzheimer’s focus directly on reducing the build-up of proteins in the brain such as amyloid and tau in patients will mild cognitive impairment, NKGen is seeking to help patients that much of the rest of the medical community has written off as hopeless cases, those with late stage Alzheimer’s. And in small studies, NKGen has shown remarkable results, even improvement in the symptoms of people with these very progressed forms of Alzheimer’s, above and beyond slowing down the disease.
In the realm of cancer, Dr. Song is similarly setting his sights on another group of patients for whom treatment options are few and far between: people with solid tumors. Whereas some gradual progress has been made in treating blood cancers such as certain leukemias in past few decades, solid tumors have been even more of a challenge. But Dr. Song’s approach of using natural killer cells to treat solid tumors is promising. You may have heard of CAR-T, which uses genetic engineering to introduce cells into the body that have a particular function to help treat a disease. NKGen focuses on other means to enhance the 40 plus receptors of natural killer cells, making them more receptive and sensitive to picking out cancer cells.
Paul Y. Song, MD is currently CEO and Vice Chairman of NKGen Biotech. Dr. Song’s last clinical role was Asst. Professor at the Samuel Oschin Cancer Center at Cedars Sinai Medical Center.
Dr. Song served as the very first visiting fellow on healthcare policy in the California Department of Insurance in 2013.He is currently on the advisory board of the Pritzker School of Molecular Engineering at the University of Chicago and a board member of Mercy Corps, The Center for Health and Democracy, and Gideon’s Promise.
Dr. Song graduated with honors from the University of Chicago and received his MD from George Washington University. He completed his residency in radiation oncology at the University of Chicago where he served as Chief Resident and did a brachytherapy fellowship at the Institute Gustave Roussy in Villejuif, France. He was also awarded an ASTRO research fellowship in 1995 for his research in radiation inducible gene therapy.
With Dr. Song’s leadership, NKGen Biotech’s work on natural killer cells represents cutting-edge science leading to key findings and important pieces of the puzzle for treating two of humanity’s most intractable diseases.
