Why TV & Movies Have Such a Strong (psychological) Influence on Society
Flickering light speaks
Borrowed lives become our own —
The screen shapes the heart.
Heroes and villains
Walk through us like memory —
Culture bends to their will.

Introduction: The Screen as a Mirror
Think about the last time a movie made you cry, or a TV show left you thinking about a character long after the credits rolled. That experience — that lingering emotional residue — is not an accident. It is the product of one of the most powerful cultural forces ever invented by human civilization. Television and film are not mere entertainment; they are, in the most fundamental sense, the storytelling engines of modern society.
For as long as humans have gathered around fires, stories have shaped how we understand the world, what we value, whom we trust, and how we behave. Today, those fires are replaced by screens — in our living rooms, on our phones, in theaters — and the storytellers are Hollywood studios, streaming platforms, and independent creators reaching billions of people simultaneously. The scale is staggering, and with that scale comes influence that no previous medium in human history has matched.
This document takes a close look at why that influence is so deep, so wide, and so persistent. We will examine the psychology, neuroscience, sociology, and cultural dynamics that make movies and TV so uniquely powerful — and what that means for all of us navigating a world increasingly shaped by what we watch.
The Brain on Story: Why Narrative Hooks Us
Let's start with the basic question: what does a story actually do to the human brain? The short answer is — a lot.
Neuroscientists have found that when we engage with a narrative, our brains do not merely process information passively. Instead, a phenomenon called neural coupling occurs, in which the brain activity of the listener or viewer begins to mirror that of the storyteller (Hasson et al., 2008). In plain language: a well-told story literally synchronizes your brain with another person's. You are not just hearing their experience — on a neurological level, you are partially living it.
Furthermore, when we encounter a compelling narrative, the brain releases oxytocin — often called the 'trust hormone' — which increases empathy and the likelihood that we will be moved to action by what we experience (Zak, 2013). Stories that generate tension and resolution are particularly effective at triggering this neurochemical chain. This is precisely why a well-crafted film can change how someone feels about an entire group of people, a social issue, or a political question in under two hours.
Movies and TV exploit this biological architecture masterfully. They combine moving image, sound, music, dialogue, and narrative arc into a single, immersive package that engages multiple sensory channels simultaneously — something a book or radio program cannot do with the same immediacy. The result is an experience that the brain encodes more like memory than media consumption.
Social Norms and Cultural Modeling
One of the most significant — and least visible — ways TV and movies influence society is through the modeling of social norms. Albert Bandura's Social Learning Theory (1977) established that people learn behaviors, attitudes, and emotional responses by observing others, especially when those others are perceived as attractive, successful, or powerful. Fictional characters on screen are, by design, all of those things.
When a character we admire handles conflict in a particular way, uses certain language, dresses a certain way, or holds specific beliefs, we are subtly influenced to see those patterns as normal, even desirable. This is not manipulation in a sinister sense — it is simply how cultural transmission works. But the implications are enormous.
Consider how television normalized smoking in the mid-20th century, how it eventually helped normalize interracial relationships, gay characters, and complex female leads over subsequent decades, and how it continues to shape perceptions of professions from law enforcement to medicine. A landmark study by Gerbner et al. (1986) found that heavy television viewers significantly overestimated the prevalence of crime in real life because crime drama was so overrepresented on TV — a phenomenon they called the Cultivation Effect. What we see (hear) repeatedly, we begin to accept as reality.
This cuts both ways, of course. Representation matters because media depictions shape who society sees as capable, heroic, and fully human. The absence of certain groups from screens — or their presence only in limiting or negative roles — has real-world consequences for how those groups are treated and how they perceive themselves.
The Parasocial Relationship Phenomenon
Here is something remarkable: research consistently shows that people form genuine emotional attachments to fictional characters and to the actors who portray them — attachments that function, psychologically, in ways similar to real friendships.
Horton and Wohl (1956) first described these one-sided connections as 'parasocial relationships,' and decades of subsequent research have confirmed that they are real, meaningful, and consequential. We feel joy at a character's triumph, grief at their death, and genuine anxiety when their future is uncertain. We argue about fictional characters as though they were real people, because in a very important sense — within the architecture of our emotional and social brains — they are.
This parasocial bond amplifies the influence of media considerably. When we trust and care about a character, we are more likely to be influenced by their worldview, their choices, and the values the narrative endorses through them. A viewer who has spent six seasons watching a morally complex character navigate a difficult world is primed to engage with ideas through that character's lens in ways they might not through a news segment or a lecture.
Parasocial relationships also explain the celebrity culture that surrounds actors themselves. Audiences who feel bonded to a performer are more likely to follow their public advocacy, adopt their aesthetics, buy products they endorse, and vote for causes they champion. This is audience influence extended from the fiction into the real world — and it is extraordinarily powerful.
Agenda Setting, Framing, and Public Opinion
Beyond storytelling, film and television also function as agenda-setting machines — that is, they shape not just what people think, but what people think about. The theory of agenda setting, originally developed in the context of news media by McCombs and Shaw (1972), applies equally well to entertainment content.
When a major streaming platform releases a documentary about a social issue, interest in that issue spikes measurably. When a prestige drama explores addiction, poverty, racial injustice, or war, audiences suddenly have a shared framework for discussing those subjects. Entertainment media creates cultural touchstones that make certain conversations possible — and others seem less urgent by comparison.
Framing is equally important. A film about the same historical event can produce radically different audience responses depending on whose perspective it centers, what music accompanies key scenes, which characters are humanized and which are not. These are editorial choices, and they carry ideological weight whether or not the filmmakers consciously intend them to.
Research by Mutz and Goldman (2010) demonstrated that fictional television portrayals of political scenarios can shift audience attitudes on real policy questions — sometimes more effectively than factual reporting. This is because narrative generates empathy, and empathy generates persuasion, in ways that data alone rarely achieves.
Violence, Fear, and the Cultivation of Reality
No discussion of media influence would be complete without addressing the long-running and often contentious debate about violence on screen. The research here is nuanced, but several conclusions have gained strong empirical support.
The Cultivation Theory developed by George Gerbner and his colleagues (1986) remains one of the most replicated findings in media studies. Heavy viewers of violent television consistently perceive the world as more dangerous than it actually is — what Gerbner called the 'Mean World Syndrome.' This distorted perception has downstream effects on political attitudes, trust in institutions, support for punitive policies, and general social anxiety.
The question of whether media violence directly causes violent behavior in viewers is more complicated. The consensus in contemporary media psychology is that violent media is one risk factor among many, and that its effect is most significant for individuals already predisposed to aggression, for children in formative developmental periods, and in contexts where real-world conditions reinforce the media message (Anderson et al., 2010). It is not a simple cause-and-effect relationship, but it is not zero either.
What is clearer is that the consistent portrayal of violence as exciting, consequence-free, and effective at solving problems can normalize attitudes toward real-world aggression. This is particularly concerning in contexts where media depictions of violence are stylized and glamorized, and where audiences have limited access to corrective real-world experience.
Advertising, Consumer Culture, and the Economy of Desire
Television and film have always been commercially intertwined with advertising, and this relationship has shaped consumer culture at a foundational level. The average American adult is exposed to several thousand advertising messages per day, a significant proportion delivered through or adjacent to entertainment content (Stelzner, 2021).
But the influence goes well beyond individual ads. Entertainment media as a whole communicates powerful messages about what constitutes a desirable life — what kind of home to aspire to, what kind of body is attractive, what brands signal status, what experiences are worth having. These are not incidental details; they are part of the cultural architecture that drives consumer behavior on a massive scale.
Product placement — the practice of integrating brand-name products directly into film and television narratives — has grown into a multi-billion dollar industry precisely because it is effective. When a character we admire and trust uses a particular product, the brand benefits from that parasocial endorsement in ways a traditional advertisement cannot replicate. The audience's guard is down; they are inside a story, not watching a commercial.
The Power for Good: Empathy, Awareness, and Social Change
It would be incomplete and unfair to discuss media influence solely in terms of risk. Television and film have also been among the most powerful forces for positive social change in modern history — and this deserves equal attention.
Documented instances of media-driven social progress are numerous and well-studied. The TV drama All in the Family in the 1970s used comedy to expose the absurdity of racial prejudice to audiences who had never seen such attitudes challenged on prime-time TV. Roots (1977) gave millions of white Americans their first emotionally engaged encounter with the realities of American slavery. Philadelphia (1993) humanized AIDS patients at the height of epidemic fear and stigma. More recent productions including Schitt's Creek, Pose, and Queer Eye have substantially shifted public attitudes toward LGBTQ+ communities, particularly among viewers who have little personal contact with those communities in daily life (Bond & Compton, 2015).
This is the empathy function of storytelling at its most valuable. When we walk in a character's shoes — when we feel their fear, their hope, their humiliation, their joy — we are less able to dismiss their humanity. This is what good storytelling does, and the reach of film and television means it can do this simultaneously for millions of people in a way that no prior medium could achieve.
Public health campaigns have also harnessed narrative entertainment with measurable results. The 'entertainment-education' strategy — deliberately embedding prosocial messages in popular dramas — has been used worldwide to change attitudes and behaviors related to contraception, HIV prevention, domestic violence, and literacy (Singhal & Rogers, 1999). The research consistently shows that story-based health messaging outperforms didactic approaches.
Children, Development, and the Screen
Children are arguably the demographic most significantly shaped by media consumption, and the developmental research in this area carries particular weight. Children are still forming their understanding of the social world, their sense of identity, their emotional vocabulary, and their model of how relationships work — and media plays a substantial role in all of these processes.
A meta-analysis by Mares and Woodard (2005) found that exposure to prosocial television content was consistently associated with positive social behavior in children — cooperation, altruism, reduced aggression — while exposure to antisocial content showed the reverse pattern. The relationship is not deterministic, but the effect sizes are meaningful and the evidence is substantial.
Children also look to media for identity cues — seeing characters who look like them, come from backgrounds like theirs, and navigate challenges they recognize. Research consistently shows that children from underrepresented groups benefit measurably from seeing positive, complex portrayals of characters who share their identity. The inverse is also true: children who rarely see themselves on screen — or see themselves only in negative roles — show measurable effects on self-esteem and social expectation.
The Streaming Age: Scale, Personalization, and the New Landscape
Everything we have discussed is amplified in the current streaming era. Platforms like Netflix, Amazon Prime, Disney+, and others reach global audiences simultaneously, offer nearly unlimited content, and deploy sophisticated algorithms designed to maximize viewing time by identifying and reinforcing each viewer's existing preferences.
This creates a paradox. On one hand, the streaming era has democratized storytelling in remarkable ways, funding stories from cultures and communities that Hollywood historically ignored. On the other hand, algorithmic recommendation systems create what critics call 'filter bubbles' in which viewers are consistently directed toward content that confirms their existing worldviews, amplifying rather than challenging their assumptions.
The binge-watching model also intensifies narrative immersion in ways that traditional weekly broadcast television did not. Spending twelve consecutive hours in the world of a single series creates a level of sustained emotional engagement that was previously impossible for most viewers — deepening parasocial bonds, amplifying cultivation effects, and extending the period of media-induced neurological synchronization (Flayelle et al., 2020).
We are, in many ways, still catching up with the social and psychological implications of this new media environment. What we know with confidence is that the mechanisms of influence identified across decades of research have not become less relevant — they have become more so.
Conclusion: Navigating the Story
Television and film are powerful precisely because they do what human beings are biologically wired to respond to: they tell stories.
They engage our brains at a neurochemical level, build emotional bonds with characters, model social norms and values, set the cultural agenda, and reach billions of people with a consistency and intimacy that no previous medium has approached.
That power is morally neutral on its face. It has been used to reinforce prejudice and to dismantle it, to inspire empathy and to manufacture fear, to sell products and to save lives. The question is not whether media influences society — that question has been answered definitively and repeatedly by the research. The question is what we do with that knowledge.
For individual viewers, it means developing media literacy — the capacity to watch critically, to recognize the conventions and choices that shape the stories we are told, and to actively interrogate the values those stories embed.
For creators, it means taking seriously the responsibility that comes with the scale of their reach. For parents, educators, and policymakers, it means treating screen time not as a passive activity but as an active curriculum — one with enormous potential for both harm and benefit.
The screen is, at its best, a window into human experience wider than any single life could encompass. At its worst, it is a mirror that reflects only what is most profitable to show us. Learning to tell the difference is, increasingly, one of the essential skills of modern life.
