“Oh, I watch crime documentaries for fun” — sound familiar? We all know someone who is completely unfazed by graphic violence on screen. Or perhaps we are that person. Have you ever wondered why footage of a serial killer leaving a trail of victims no longer disturbs most of us? Is it because our brains know it is fiction — or is something deeper at play? When exactly did violence stop being shocking and start becoming entertaining?
Contemporary audiences consume more television, film, web series, and online content than any generation before them. With every grisly crime drama, graphic action film, and dystopian thriller, we have grown increasingly accustomed to imagery that would have horrified viewers just a few decades ago. The concern is not that consuming violent media turns people into violent individuals. The more pressing and subtle concern is this: are we becoming quietly comfortable with violence as a form of entertainment — and what does that comfort cost us?
How Violence in Media Has Changed Over Time
Violence has always existed in entertainment, but its presentation has changed dramatically. In earlier eras, violence was implied rather than shown — interpretative, leaving room for imagination. The shower scene in Alfred Hitchcock’s Psycho caused widespread outrage and controversy in 1960, despite showing remarkably little by modern standards; it was filmed in black and white, and the ‘blood’ was chocolate syrup. Today, audiences watch scenes far more graphic without batting an eye. Television series like The Boys, Game of Thrones, and Squid Game integrate violence so seamlessly into compelling narratives that viewers absorb brutality almost without noticing.
The entertainment industry’s need to retain viewer attention is partly responsible for this escalation. Graphic content keeps audiences engaged, and as viewers grow accustomed to a certain level of intensity, creators raise the stakes further. Early filmmakers relied predominantly on atmosphere and suggestion to build dread. The horse’s head scene in The Godfather (1972) was terrifying not because of what was shown, but because of what it silently communicated about the Corleone family’s power. Films of the German Expressionist era, such as Nosferatu, used shadows and atmosphere to generate fear. Today, films like Terrifier 3 feature levels of graphic gore that would have been unimaginable in mainstream cinema decades ago. The graph of acceptable screen violence has grown exponentially.
The Psychology and Neuroscience of Desensitization to Violence
When people encounter violent imagery for the first time, their bodies respond physiologically. The brain perceives threatening images and reacts with anxiety, muscle tension, intrusive thoughts, and elevated blood pressure. However, with repeated exposure, these responses diminish. This is desensitization — and it is not merely psychological but neurological.
One key brain region involved is the amygdala, which processes fear and emotional reactions. When people encounter violent imagery, it typically activates a fight-or-flight response. Studies using brain imaging techniques have found that repeated exposure to violent media can reduce activity in areas associated with emotional processing, including the amygdala. The brain gradually begins to register gore as something ordinary rather than threatening. This does not mean a person stops recognising violence as harmful — but it does mean the visceral shock response becomes progressively muted.
One of the most influential studies on media violence effects was conducted by psychologists Craig Anderson, Nicholas Carnagey, and Brad Bushman in 2007. Participants repeatedly exposed to violent media showed significantly lower physiological responses when later shown real acts of violence, compared to participants who had not been pre-exposed. Research by Anderson and Bushman also found that playing violent video games was associated with increased aggressive thoughts and reduced prosocial behaviour — participants were slower to help people in need after gaming sessions. A separate study published in the journal Aggressive Behavior found that repeated exposure to violent film scenes reduced sympathy for victims over time, as participants became progressively less emotionally affected.
The True Crime Effect
Streaming platforms have made exposure to media violence far more pervasive. Viewers can now binge violent dramas, thrillers, and documentaries for hours without interruption. True crime content presents a particularly striking case study. Documentaries about serial killers and infamous murders have become enormously popular — productions like Making a Murderer, Dahmer, and Conversations with a Killer have repackaged real human tragedies as entertainment products. The uncomfortable reality is that this format can reduce the weight of victims’ suffering, subordinating it to the thrill of the narrative.
Crime show popularity is not inherently sinister — curiosity about human behaviour, justice, and the psychology of violence in entertainment is entirely natural. But the format matters. When real tragedies are edited for pacing, scored with ominous music, and structured like thrillers, they condition audiences to experience horror as entertainment rather than as moral weight.
Not Everyone Agrees — But the Question Remains
It is worth noting that not all researchers agree on the extent to which media violence shapes real-world behaviour. There are millions of people who regularly consume violent content without exhibiting aggressive or antisocial traits. Researcher Christopher Ferguson, among others, argues that aggression is primarily determined by social environment, childhood experience, poverty, and mental health — not screen content.
But even setting aside the question of violent behaviour, the question of desensitization to violence remains. The concern is not about turning people into criminals. It is about a quieter shift in emotional response. Consider this: after weeks of scrolling through news coverage of the ongoing conflict in Gaza, seeing images of children suffering barely registered the same emotional response as it might have earlier. The same images that brought older generations to tears might be absorbed by younger, heavily media-saturated viewers with a kind of numb, exhausted familiarity. That shift — from shock to resignation — is precisely what desensitization looks like in daily life.
The greatest danger of contemporary entertainment is not that it teaches people to be violent. It is that it teaches people to be comfortable with violence. Media can educate, illuminate, and help audiences make sense of difficult realities. The problem arises when constant exposure turns human suffering into background noise — something scrolled past, streamed, and forgotten before the credits roll.
