Social Media Influencers Amplify Misinformation Through Unique Follower Relationships, Study Finds
Social media influencers can significantly exacerbate the spread of misinformation online due to the distinctive relationships they cultivate with their followers, according to new research from Cardiff Business School.
In a groundbreaking study published in the journal Psychology & Marketing, researchers analyzed brand-related misinformation and user comments across 47 brands in nine different industries over a three-year period. The study marks the first comprehensive measurement of toxicity levels generated by influencers compared to regular social media users.
The findings come at a time when brands are increasingly dependent on social media influencers (SMIs) to connect with target audiences, with industry investments projected to reach a record $33 billion in influencer marketing in 2025. While influencers have become crucial for product endorsements, the research reveals a troubling dynamic within the communities they create.
“Our findings show influencers generate more toxicity than regular users, amplifying content under the same conditions that enhance their visibility and influence,” explained lead author Dr. Giandomenico Di Domenico. “While regular users might see inaccurate posts called out and critiqued, the unique parasocial bond influencers have with their communities means these groups are much more likely to get behind an idea without interrogating its veracity.”
The study identified a striking contrast in how misinformation spreads depending on its source. When regular social media users share incorrect information, they typically face immediate confrontation and criticism, motivating them to steer conversations toward more civil discourse and correct inaccuracies as engagement grows. Influencers, however, experience the opposite effect—their profits increase with engagement, regardless of content accuracy.
Researchers identified two specific mechanisms through which influencers boost the reach and impact of misinformation: legitimation, where the influencer lends credibility to a theory; and community enmeshment, where their followers rally behind the claims without question. When these elements combine, they create what researchers describe as “toxic echo chambers,” converting influencer credibility and parasocial bonds into “collective antagonism.”
The analysis revealed toxicity peaks particularly when influencers discuss socio-political issues, where public stakes are higher. As engagement increases, it produces what the researchers term a “self-reinforcing toxicity-engagement spiral.”
A notable example occurred in early 2025, when several TikTok influencers shared viral videos claiming that luxury brands like Hermès, Louis Vuitton, and Chanel secretly manufactured their products in Chinese factories while falsely marketing them as “Made in France” or “Made in Italy.” Despite providing no verifiable evidence, these videos amassed millions of views and triggered widespread debate about authenticity and transparency in the luxury sector.
“This case highlights a growing paradox in influencer culture,” noted Dr. Di Domenico. “Despite the positive impact of SMIs on marketing outcomes, their prominence also introduces new risks, particularly when controversial or misleading content sparks toxic reactions directed at brands.”
The research underscores the importance of understanding how toxicity manifests differently when misinformation originates from influencers rather than regular users, given the distinct levels of influence, credibility, and audience engagement that influencers command.
For brands increasingly relying on influencer partnerships, the study serves as a warning about potential reputational risks. It suggests companies may need to develop more sophisticated approaches to monitoring influencer content and implementing crisis management strategies when influencer-driven misinformation targets their products or services.
