In an era when young people are more likely to scroll than vote, a new study in Human Communication Research reveals that social media influencers may hold the key to rekindling collective political engagement. Researchers Pascal Merz and Christian von Sikorski found that influencers who share socially meaningful messages - especially about issues like climate change - can boost their followers' belief in the power of collective action and inspire them to participate in civic life.
From Likes to Action
The study builds on the classic two-step flow of communication model, where information travels first through opinion leaders before reaching the wider public. In the digital age, influencers have become these new opinion leaders - bridging the gap between mass media and personal connection. But Merz and von Sikorski's work adds a crucial psychological dimension: parasocial relationships (PSRs), the one-sided yet emotionally real bonds followers form with influencers.
Across three large studies involving nearly 3,000 participants - including a real-world experiment with a lifestyle influencer and her 600,000 Instagram followers - the researchers found that influencer posts emphasizing collective response efficacy ("Together, we can make a difference") significantly increased followers' belief that joint effort can change society. This effect was especially strong among followers who already felt personally close to the influencer.
The Power of "We"
Individual effort alone rarely solves problems like climate change or systemic inequality. What drives social movements, the study shows, is not personal optimism but collective efficacy - the conviction that our group can achieve meaningful change. When influencers frame issues through this collective lens, they transform passive spectators into potential participants.
The key phrase is not "you can help," but "we can help." That subtle linguistic shift activates a shared identity between influencer and audience. For followers who see their favorite influencer as a trusted friend, this message feels like a personal invitation to join a cause - turning fandom into civic motivation.
Parasocial Trust: The Hidden Multiplier
The researchers found that this effect only emerged among followers with strong parasocial bonds. Those who felt little connection to the influencer were unaffected, even when exposed to the same message. In other words, influence is not a matter of reach - it's a matter of relationship.
This finding redefines digital opinion leadership. Traditional media measured influence by audience size; this study shows it depends on emotional proximity. Influencers who share their personal lives, express vulnerability, and maintain consistent engagement become "proximal mass opinion leaders" - figures trusted enough to move public attitudes.
Repetition Reinforces Belief
In the field study, followers who saw the influencer's message multiple times reported stronger collective efficacy and greater intent to take political action, such as voting or supporting climate initiatives. This echoes the "truth effect" observed in psychology: repetition increases perceived credibility and emotional impact.
However, the authors caution that these effects rely on authenticity. Overuse of political messaging or overt sponsorship could weaken parasocial trust, turning engagement into skepticism.
A New Architecture of Political Influence
Merz and von Sikorski's model integrates theories of collective action (Fritsche et al., 2018) and communication influence (Eveland & Cooper, 2013) into the digital ecosystem. Their conditional process framework shows how political influence now flows through personal bonds, not institutions.
It's not the algorithm that persuades people - it's the relationship layer embedded within it. When a trusted influencer speaks about a social issue, followers process the message through the same neural and emotional channels they reserve for friendship. This bypasses cynicism and fosters identification, turning "content consumption" into "collective participation."
Implications
The findings suggest a major shift in how social movements and policy campaigns might reach younger generations. Instead of traditional top-down messaging, collaboration with influencers - particularly those who communicate authenticity and community - may build the collective confidence required for real-world change.
But this influence also carries ethical weight. The same parasocial mechanisms that can inspire climate activism could also be weaponized to spread misinformation or polarization. As the authors note, understanding the psychological infrastructure of influence is crucial to ensuring it empowers rather than manipulates.
The Future of Digital Solidarity
In a time of fragmented media and declining institutional trust, influencers may be the new architects of collective belief. Their voices can bridge isolation with belonging, transforming shared attention into shared purpose.
As Merz and von Sikorski conclude, "Influencers can mobilize followers in their collective political views and action intentions - if a strong parasocial relationship already exists." The message is clear: connection precedes conviction.
