Trigger warnings

However, while trigger warnings are widely used, their actual effectiveness remains debated. A recent meta-analysis published in Clinical Psychological Science (Bridgland, Jones, & Bellet, 2024) examined the impact of these warnings, revealing surprising findings about their influence on emotional responses, learning, and anticipatory anxiety.

This article explores the key takeaways from this research, PTSD UK’s perspective on trigger warnings, and why ensuring choice and accessibility—rather than removing trigger warnings entirely—must be the focus of this discussion.

What Are Trigger Warnings Supposed to Do?

The rationale behind trigger warnings is simple: by giving individuals a heads-up about sensitive content, they can prepare themselves mentally and emotionally or even choose to avoid the material entirely. This is particularly relevant for individuals with PTSD, who may experience distressing symptoms when confronted with reminders of their trauma.

The primary goals of trigger warnings include:

• Reducing emotional distress by allowing individuals to brace themselves before exposure to potentially upsetting material.
• Providing a sense of control by giving people the option to engage with or avoid the content.
• Creating a safer environment where people feel supported and protected from unnecessary emotional harm.

On the surface, this approach seems beneficial—but does the research support its effectiveness?

What the Research Says About Trigger Warnings

The recent meta-analysis by Bridgland, Jones, and Bellet (2024) synthesized data from multiple studies examining the effects of trigger warnings across various settings. The key findings include:

1. Trigger Warnings Do Not Reduce Emotional Distress

One of the most striking findings is that trigger warnings do not significantly reduce the emotional impact of distressing material. Whether or not a warning was given, participants in the studies experienced similar levels of distress when engaging with the content.

This suggests that while people might appreciate being forewarned, it does not necessarily soften the emotional response to the material itself.

2. They Have No Effect on Learning or Comprehension

In educational settings, trigger warnings are often used to prepare students for potentially distressing topics. However, the meta-analysis found that warnings did not improve or hinder comprehension and learning.

This challenges the idea that trigger warnings help students engage more effectively with difficult material. Instead, they appear to be neutral in this regard.

3. Trigger Warnings Can Increase Anticipatory Anxiety

Perhaps the most concerning finding is that trigger warnings may actually heighten anxiety before exposure to distressing material. When individuals were given warnings, they often experienced increased anticipatory anxiety—worrying more about the content before they even engaged with it.

For individuals with PTSD, this could mean that rather than helping, trigger warnings might actually amplify distress by making them more focused on the potential for harm. Critics also contend that trigger warnings may inadvertently promote avoidance behaviors, which can be counterproductive to evidence-based therapeutic practices.

PTSD UK’s Stance on Trigger Warnings

At PTSD UK, we do not generally use trigger warnings on our content. All of the information we share has the potential to be a trigger, as PTSD triggers are highly individual and can stem from almost anything—a sound, smell, something seen, a place, or a person.

However, we do acknowledge that some topics, such as self-harm or suicide, can be particularly distressing. In these cases, we include a sensitive content warning to help people recognise that difficult subjects will be discussed, allowing them to make an informed decision.

The reason we do not use broad trigger warnings is twofold:

• Minimising some experiences over others – If we place a warning on an article about sexual assault but not on an article about a road traffic incident, it could suggest that the trauma from the latter is less significant. All PTSD triggers are valid, and we do not want to rank them in importance.
• Avoiding the assumption of triggers – With PTSD, almost anything can be a trigger. If we warn about some things but not others, it assumes we can predict what might be triggering for someone, which is not possible.

Instead of trigger warnings, we focus on providing the tools and support needed to navigate difficult topics in a healthy, self-directed way.

Trigger Warnings in Education,  the Workplace and Media

Media (Films, TV, Books, Theatre, Gaming)

• Interactive opt-ins: Streaming platforms, video games, and online articles could offer customisable content filters where users can choose which types of warnings they want to see (e.g., Netflix allowing users to toggle content descriptions).
• Time-stamped or scene-specific warnings: Instead of a blanket warning at the start, some media (like Disney+ and HBO Max) already provide pre-scene notifications when a particularly distressing moment is coming.
• Creative implementation in theatre and live performances: Programmes and websites could include content notes rather than verbal trigger warnings before a show, so those who want to be aware can read them while others can avoid them if they prefer. Some productions, like Prima Facie, have introduced wellbeing guides and quiet spaces for audience members who may find the content distressing.

Workplaces

• Pre-session disclosures: For difficult discussions (e.g., diversity and inclusion training, harassment policies, or trauma-related work), employees could be given advance notice with a clear option to participate or not.
• Anonymous feedback channels: Employers can provide a way for staff to privately share concerns about potentially distressing content without fear of judgement.
• Peer support networks: Encouraging mentorship or peer support groups for employees who may find certain topics challenging in their professional environment.

Education (Schools & Universities)

• Syllabus transparency: Instead of individual trigger warnings, institutions could adopt a “content roadmap” at the start of each course, detailing topics covered so students can plan accordingly.
• Flexible engagement methods: In literature or history classes, students who may struggle with certain materials could be given the choice to engage through discussion, summaries, or alternative texts.
• Training for educators: Teachers and lecturers should be trained in trauma-informed teaching so they can guide difficult discussions sensitively rather than relying solely on warnings.

Public Spaces & Events

• Museums and exhibitions: Institutions such as the Imperial War Museum already provide content guidance on sensitive exhibitions rather than blanket warnings. This approach allows visitors to engage at their own comfort level while maintaining historical integrity.
• Public talks and conferences: Speaker events could include session descriptions with sensitivity notes, allowing attendees to make an informed decision about participation.

Instead of binary trigger warnings, a more effective approach is detailed, structured, and optional content notes, combined with informed choices and accessible support. By implementing more nuanced, trauma-aware practices, workplaces, media, and education can remain inclusive and supportive while ensuring people feel empowered rather than restricted.

Ultimately, the goal should be to strike a balance between creative freedom and audience awareness, ensuring that people are given the autonomy to decide what is right for them while avoiding unnecessary fear or avoidance.

Alternative Approaches to Supporting People with PTSD

Rather than removing trigger warnings entirely, the conversation should shift towards providing accessible and flexible options:

• Sensitive content warnings instead of ‘trigger warnings’ – Using terms like “Sensitive Content: Includes themes of sexual violence” removes assumptions while still offering awareness.
• Providing opt-in options – Giving students, employees, and audiences the choice to engage or step away if needed.
• Post-exposure support – Ensuring access to helplines, mental health resources, or debrief spaces for those who need them after engaging with difficult material.
• Recognising individual needs – Acknowledging that different people have different responses and respecting their right to make informed choices about the content they consume.

Final Thoughts

Trigger warnings should not be seen as an attack on free speech, artistic integrity, or academic freedom, nor should they be dismissed entirely. While research suggests they may not always reduce distress, they remain an important accessibility tool in certain contexts—particularly when discussing topics that are widely recognised as highly distressing.

In education, the workplace, and public spaces, the focus should not be on whether trigger warnings should exist at all, but rather how they can be used effectively. Instead of simply labelling content as “triggering”, they should be thoughtfully implemented—providing clear, factual information about sensitive content, allowing people the choice to engage or prepare themselves in a way that supports their mental health.

At PTSD UK, we believe that choice and accessibility matter. By improving how trigger warnings are used, rather than removing them, we can ensure that inclusivity and awareness remain at the heart of discussions, performances, and learning environments.

Ultimately, it’s not about limiting experiences—it’s about making sure everyone has the opportunity to take part in them safely and with autonomy.
