The gilded curtain is about to rise on CrimeCon’s first European outing, descending on London’s ExCeL centre this weekend. But as thousands of true crime devotees prepare to dissect the darkest corners of human nature, a chorus of British mental health experts is sounding an urgent alarm: the spectacle could be doing more harm than good.
For the uninitiated, CrimeCon is a travelling carnival of the macabre. Think TED Talks meets a murder mystery dinner, featuring forensic psychologists, retired detectives and even convicted criminals sharing their stories. It’s a phenomenon that has sold out arenas in the US, and now it’s crossing the Atlantic with the promise of ‘immersive’ panels on serial killers and unsolved cases. But beneath the buzz, a more troubling narrative is emerging.
Dr. Eleanor Shaw, a consultant psychiatrist at the Maudsley Hospital in London, puts it bluntly. “We are seeing a rise in what we call vicarious trauma, or secondary traumatic stress, among consumers of true crime content. It’s not a formal diagnosis, but the symptoms are real: intrusive thoughts, hypervigilance, even nightmares. For individuals with a history of trauma or anxiety, the effect can be devastating.”
Her concerns are echoed by Dr. Raj Patel, a clinical psychologist specialising in trauma. “The problem with events like CrimeCon is that they blur the line between education and voyeurism. When you have six hours of laser focus on the most violent acts humans can commit, you are essentially asking the brain to process an emotional overload. The amygdala goes into overdrive, and the prefrontal cortex struggles to keep up. It’s a recipe for digital-age PTSD.”
The numbers bear this out. A 2023 study by the University of Leicester found that 36 per cent of regular true crime consumers reported symptoms of anxiety or depression linked to their viewing habits. Another survey, by mental health charity Mind, showed that 22 per cent of respondents felt ‘worse about the world’ after exposure to true crime content. The irony is that many attendees insist they come for the ‘solidarity’ and ‘community’, but the immersive stagecraft of CrimeCon might be deepening the very fears they seek to understand.
CrimeCon’s organisers, of course, push back. In a statement, they say they “prioritise attendee wellbeing” and that mental health professionals will be on site. They point to the ‘safe space’ policy and content warnings. But critics argue that the very format of a live event, where you cannot look away from a screen or change the channel, makes it exponentially more potent. “You are trapped in the experience,” says Dr. Shaw. “Your flight or fight response is engaged, but you cannot flee. That is a recipe for psychological harm.”
The UK’s National Advisory Council for Survivors of Crime has gone further, calling for a pause on the event until more research is done. Their concern is not just for attendees but for the wider cultural impact. When we commodify tragedy, they argue, we risk normalising violence and diminishing empathy for real victims. We risk turning murder into entertainment, and that is a very slippery slope.
Yet the demand for such content is undeniable. Ticket sales for CrimeCon London have been brisk, with over 15,000 tickets sold already. The streaming giants have long fed this appetite, with true crime consistently ranking among the most-watched genres on Netflix and Spotify. What CrimeCon does is add a social layer: you are not just watching, you are participating, sharing gasps and theories with a room full of strangers. And for some, that shared experience is therapeutic, a way to wrestle control back from a chaotic world.
But for others, it may be a step too far. The British Psychological Society has issued guidance for attendees: take breaks, avoid late-night sessions, and stay aware of your emotional state. It is a stark reminder that even in the age of personalised algorithms and curated feeds, our brains still have not caught up with the content we consume.
As I sit here, parsing the research and the warnings, I cannot help but think about the ‘user experience’ of society. We are building a world where engagement is the only metric, where our digital dopamine cycles are increasingly fed by the darkest impulses. CrimeCon is a microcosm of that: an algorithm-driven experience designed to keep us hooked, but at what cost? The silence from the tech platforms that fuel this demand is deafening.
So as the crowds gather in London this weekend, we should watch not just the stage, but the audience. We should listen for the quiet stories of distress among the excited chatter. Because the true crime story that matters most may not be the one playing on the big screens, but the one unfolding in the minds of the people watching.
