Older Adults More Likely to Share Misinformation, Not Due to Poor Fact-Checking Skills

The age of social media has introduced unprecedented challenges in information dissemination, with misinformation spreading at alarming rates across digital platforms. A new study reveals that adults over 55 are significantly more likely to share political misinformation online – not due to technological unfamiliarity as commonly assumed, but because of stronger partisan biases.

Researchers found that older adults can generally distinguish between fake and real news but are more influenced by whether the content aligns with their political beliefs. This finding highlights how confirmation bias – our natural tendency to favor information that reinforces existing views – plays a critical role in the spread of misinformation.

“We found that older people are more likely to believe as true and to share information that aligns with their party, whether that information is true or not,” explained Leaf Van Boven, professor in the Department of Psychology and Neuroscience at the University of Colorado Boulder, who served as senior author on the study.

The research, conducted by Van Boven and Guilherme Ramos, assistant professor of marketing at the Rochester Institute of Technology, examined how age affects susceptibility to political misinformation. Their comprehensive analysis involved 2,400 participants across Brazil and the United States, spanning ages 18 to 80.

In their methodology, participants were presented with various political headlines, some factually accurate and others previously debunked by fact-checking organizations. The headlines were strategically designed to appeal to different political ideologies, with some favoring Republican perspectives and others leaning toward Democratic or liberal viewpoints.

Examples included false headlines such as “Pope Francis shocks world and endorses Donald Trump for President,” “Bolsonaro wants to cut 25% of civil servants’ salaries,” and “Pence: Michelle Obama is the most vulgar first lady we’ve ever had.” Participants were asked about their likelihood of sharing such news on social media and whether they believed the claims were true or false.

The results were illuminating: participants aged 55 and older demonstrated the same overall ability to identify fake news as younger adults. However, they showed significantly stronger partisan biases in their assessments, making them less likely to recognize misinformation that supported their political beliefs and more quick to identify falsehoods that contradicted their ideological preferences.

“They had different standards of evaluating evidence depending on whether it reflected well on their side or not,” Van Boven noted.

The findings align with previous research showing that aging often intensifies confirmation bias. Several studies have established that older adults tend to share more misinformation overall, but this new research clarifies that the driving factor is increased partisanship rather than cognitive decline or technological illiteracy.

From an evolutionary perspective, confirmation bias serves as a mental shortcut that allows for faster decision-making by prioritizing information that aligns with existing beliefs. While this mechanism can be efficient, it becomes problematic in today’s information-saturated environment, particularly on social media platforms where partisan content can quickly create echo chambers that reinforce and amplify existing beliefs.

The implications extend beyond individual behavior to broader societal concerns about political polarization and democratic discourse. As social media platforms continue to serve as primary news sources for many Americans, understanding the psychological mechanisms behind misinformation sharing becomes increasingly important.

The researchers recommend that individuals practice greater self-awareness when sharing content online, taking time to evaluate their own biases before hitting the share button. Van Boven particularly emphasizes the importance of maintaining social connections across political divides.

“As someone who studies political polarization, I am very much in favor of inter-group contact. It’s critical for a healthy democracy that we can talk to and have friends who think differently,” he said.

The study, published in ApaPsycNet, contributes valuable insights to ongoing efforts to combat misinformation and highlights the need for approaches that address partisan biases rather than simply focusing on digital literacy. As election seasons approach and political content proliferates online, understanding these psychological factors becomes essential for fostering a more informed citizenry.
