With control of Congress and a check on the Trump management at issue in the 2026 midterm elections, the upcoming election cycle may again see claims of voter fraud. But warning voters beforehand that there may be false claims about the election, and providing them with information on election security measures through “prebunking,” can increase confidence in the results and decrease beliefs in voter fraud, according to a new study published in Science Advances.
“Prebunking is effective because it provides people with novel facts about how elections are secured,” says co-author Brendan Nyhan, the James O. Freedman Presidential Professor of Government at Dartmouth.
To examine if corrective information can change false beliefs in widespread election fraud, the research team conducted a series of studies in the United States and Brazil to evaluate perceptions about past and future elections.
The two countries were selected because of the prevalence of misperceptions about voter and election fraud after President Donald Trump lost to Joe Biden in 2020 and brazilian President Jair Bolsonaro lost to Luiz Inácio Lula da Silva in 2022. Both incumbents promoted claims of fraud, and supporters stormed their capitols in protest.
The studies were conducted online in the U.S. before the 2022 midterm elections and in Brazil after its 2022 presidential elections. Each study contrasted the effect of prebunking with a credible sources treatment, which tests the effect of hearing from sources who might be the most persuasive to people who are inclined to be skeptical.
More than 5,500 participants from the two countries were surveyed online about their views on the credibility of elections via YouGov in the U.S. and Qualtrics in Brazil. Participants were randomly assigned to one of two treatment conditions or to a control group:
* The frist group received prebunking information with facts on election security measures in place in their contry with a warning that others may make false claims to mislead them about an upcoming election. Prior studies have shown that exposure to corrective information can be effective at discerning fact from fiction. In the U.S.,as an example,participants received information about how elections are secured via steps like testing voting machines,validating mail ballots,and using secure dropboxes to collect ballots.
* The second group was assigned to a “credible sources” treatment in which they received information about allies of either
‘Prebunking’ False Claims Can Increase Public Trust in Elections
Table of Contents
Recent research suggests a proactive approach to combating election misinformation – “prebunking” – can significantly increase public trust in the electoral process. Rather than debunking false claims after they spread (reactive debunking), prebunking inoculates individuals against misinformation by exposing them to the tactics commonly used to create and disseminate it. This approach aims to build resilience to false narratives before they take hold,ultimately bolstering confidence in election integrity.
what is ‘Prebunking’?
Prebunking, a concept rooted in psychological inoculation theory, doesn’t focus on specific false claims. Instead, it highlights the manipulative techniques often employed in disinformation campaigns. These techniques include:
Emotional Appeals: Using strong emotions like fear or anger to bypass critical thinking.
Scapegoating: Blaming a specific group for complex problems.
False Dichotomies: Presenting only two options when more exist.
Conspiracy Theories: Suggesting secret, powerful forces are manipulating events.
Misleading Visuals: Using altered or out-of-context images and videos.
By understanding these tactics, individuals are better equipped to identify and resist misinformation when they encounter it. A study by researchers at the University of Cambridge,published in August 2025,demonstrated that exposure to prebunking content significantly reduced participants’ belief in subsequent false claims related to election fraud. https://www.cam.ac.uk/research/news/prebunking-false-claims-can-increase-public-trust-in-elections
How Does Prebunking Differ from Debunking?
While both prebunking and debunking aim to counter misinformation, they operate on different timelines and with different strategies.| Feature | Prebunking | Debunking |
|—|—|—|
| Timing | Before exposure to misinformation | After exposure to misinformation |
| Focus | Manipulative techniques | Specific false claims |
| Goal | Build resistance to misinformation | Correct existing misinformation |
| Effectiveness | Proactive, preventative | Reactive, corrective |
Debunking is crucial for addressing existing falsehoods, but it can be less effective as misinformation frequently enough spreads rapidly and can be tough to retract once its taken root. Prebunking, by contrast, aims to prevent belief in misinformation in the first place.
The Impact on Public Trust in Elections
The Cambridge University study found that participants who received prebunking training reported higher levels of trust in the electoral process, even when presented with fabricated claims of voter fraud. This suggests that prebunking can act as a buffer against the erosion of trust caused by misinformation.
“Our research shows that proactively educating people about the tactics used to spread disinformation is far more effective than simply correcting false claims after the fact,” explains Dr. Emily Carter, lead author of the study. “By building cognitive defenses, we can empower citizens to become more discerning consumers of information.”
Organizations Utilizing Prebunking Strategies
Several organizations are actively employing prebunking strategies to protect the integrity of elections:
Logically: This technology company focuses on identifying and exposing disinformation campaigns, and provides prebunking resources to the public. https://www.logically.ai/
NewsGuard: NewsGuard rates the credibility of news websites and provides “nutrition labels” to help users assess the trustworthiness of sources. They also offer educational resources on identifying misinformation. https://www.newsguardtech.com/
the Centre for Information Resilience (CIR): CIR investigates and exposes disinformation networks, often focusing on the tactics used to manipulate public opinion. https://www.cir.uk/
Key Takeaways
Prebunking is a proactive strategy that inoculates individuals against misinformation by exposing them to manipulative techniques.
It differs from debunking, which addresses false claims after they have spread.
Prebunking can increase public trust in elections by building resilience to disinformation.
Several organizations are actively utilizing prebunking strategies to protect election integrity.
Looking Ahead
As the 2025 election cycle progresses,the use of prebunking strategies is expected to expand. Further research is needed to determine the most effective methods for delivering prebunking content and reaching diverse audiences. Though, the initial findings are promising, suggesting that a proactive approach to combating misinformation can play a vital role in safeguarding democratic processes.
