There is a moment when a story stops feeling like a story and starts becoming something else. Something people repeat. Something people reference. Something that begins to sound like fact, even when no one can quite point to where it started. We call this public opinion. But public opinion is not simply what people think. It is often the result of what people have seen, heard, and encountered repeatedly. And in today’s media environment, that process is far from neutral.
The Starting Point: A Story Enters the Stream
Most stories begin as isolated pieces of information, like a post, a video, or a headline. At this stage, the story has limited reach. It exists within a small network, such as a group chat, a timeline, or a niche audience. But what matters is not just the content itself. It is also whether the story contains the elements needed to move.
Research in media and communication has shown that novelty and emotional intensity increase the likelihood of sharing. This was notably demonstrated in a large-scale study by researchers at the Massachusetts Institute of Technology, which found that false or misleading content often spreads more rapidly because it is more surprising and emotionally engaging. At this stage, the story is not yet dominant, but it is primed for movement.
Repetition: The First Layer of Legitimacy
As a story begins to circulate, repetition becomes key. The story appears in multiple posts, across different accounts, and in slightly varied forms. Psychological research has long demonstrated the illusory truth effect, which is the tendency for people to believe information is true simply because they have encountered it multiple times.
This means that repetition does more than increase visibility. It begins to build credibility. A story that appears once may be questioned, but a story that appears everywhere begins to feel familiar. And familiarity, over time, starts to feel like truth.
Amplification: From Circulation to Visibility
Not all stories that circulate become widely visible. For a story to move from small networks into broader awareness, it requires amplification. This often happens through high-following accounts, political figures, media coverage, or coordinated networks. At this stage, the story is no longer simply being shared. It is being pushed.
This aligns with the principles of Agenda-Setting Theory, developed by Maxwell McCombs and Donald Shaw, which suggests that the media does not tell people what to think, but what to think about. In a digital context, this function is increasingly shared between journalists, platforms, and networked actors. The more a story is amplified, the more it becomes part of what people perceive as important.
Convergence: When Different Spaces Align
A critical turning point occurs when a story appears across multiple information spaces. It moves from social media to radio discussions to online publications, and to everyday conversations. This convergence creates a powerful effect.
People begin to encounter the same narrative in different contexts, reinforcing the perception that it is widely accepted. At this stage, the story becomes part of the information environment and is no longer confined to a platform.
Mutation: The Story Becomes Many Stories
As the narrative spreads, it changes. Details are added, sometimes context is removed, and there is often an interpretations shift. Different groups adopt the story and adapt it to align with their own perspectives. This results in multiple versions of the same narrative, each carrying a slightly different meaning. Over time, the original version becomes less important than the collective narrative that has formed around it.
Perception: When It Becomes “What People Think”
Eventually, the story reaches a point where it is no longer introduced as a claim. It is introduced as a general understanding.
People start to say things like “Everyone is saying.. People believe that… It’s clear that…” This is the moment when a narrative becomes perceived as public opinion. But what appears to be consensus is often the result of repetition, amplification, and visibility rather than widespread independent verification.
The Role of Platforms
An important aspect that plays a key role is digital platforms, because algorithms prioritise engagement, relevance, and user behaviour. This means that content that generates strong reactions is more likely to be surfaced and recirculated.
According to research from the Reuters Institute for the Study of Journalism, audiences increasingly encounter news through platform-driven feeds rather than direct engagement with news organisations. This shifts the dynamics of how public opinion is formed. Visibility becomes personalised, and exposure becomes uneven. And yet, the perception of a shared narrative remains.
Why This Matters
Public opinion carries weight. It influences political decisions, policy debates, and media coverage. But if public opinion is shaped by how narratives move, then understanding that movement becomes essential. Because what people believe is not always the result of what is most accurate. It is often the result of what is most visible.
The next time a story feels like “something everyone believes,” it is worth asking:
How many times have I seen this?
Where have I seen it?
Who is sharing it?
What might have changed along the way?
Because public opinion is not only formed. It is constructed.
