Content Warnings

What are Content Warnings and Why Use Them?

Providing a statement to your students prior to revealing potentially distressing content is a useful way to help reduce its negative impact.

The content may be delivered via:

  • text,
  • verbal narratives,
  • URLs,
  • images,
  • figures,
  • visuals,
  • video,
  • audio, or
  • interactive activities.

A general guide is that if you find yourself pausing when adding particular content to your course; ask yourself if including it is necessary. If it is, consider a content warning. This also show students that you care about their wellbeing and safety.

Sensitive Topics

Topics often identified as potentially sensitive include, for example,

  • violence or abuse of all kinds:
    • physical,
    • emotional,
    • sexual, or
    • institutional;
  • racism;
  • homophobia;
  • transphobia;
  • eating disorders; or
  • self-harm.

You can find lists of types of material that may benefit from a content warning on the Internet. Here are two to get you started:


For those who have been adversely affected by course content, or other life experiences, students can access the Student Wellness and Counselling Centre, and instructors may avail of their Employee Assistance Program (EAP) services.

Approaches to Presenting Content Warnings

There are a few approaches to use to bring sensitive content to students attention, syllabus fair warning statement, a verbal reminder prior to sensitive material may be presented, written warning statements within course notes (physical or online), or visual/text warnings on content pages of online materials. A few examples are noted below.

Statement of Fair Warning in Syllabus

The Syllabus Resource on the Instructional Resources site, composed by the Memorial University Syllabus Working Group, recommends including a Statement of Fair Warning; see section 3. Course Information. The example they provide is:

Statement of Fair Warning. Outline content that may be personally offensive or otherwise troubling. Include instructions for students seeking alternate accommodations.

Verbal Warning

Taking a moment to give students a heads-up that the next topic covered in class may be upsetting for some will help students prepare and take decisions to protect themselves. This example of what to say, from the University of Waterloo, may be useful in formulating your own thoughts.

Next class our discussion will probably touch on the sexual assault that is depicted in the second last chapter of The White Hotel. This content is disturbing, so I encourage you to prepare yourself emotionally beforehand. If you believe that you will find the discussion to be traumatizing, you may choose to not participate in the discussion or to leave the classroom. You will still, however, be responsible for material that you miss, so if you leave the room for a significant time, please arrange to get notes from another student or see me individually.

Online Content Warnings

Here are a few images of examples used in online courses at Memorial University:

1. Blurring image of sensitive material. Reader clicks on the image to reveal the clearly presented content.images of fried rats and a goat fetus have been deliberately blurred, with warnings, so users can choose to view the originals
2. A notice box with icon and ‘Trigger Warning’: followed by explanation of the nature of the possibly disturbing content.
3. A notice box with icon and list of types of possibly disturbing contenttext is: Content Warning CW// sexual assault, violence, murder
4. Visual signs of content warningsvarious warning icons and images to alert readers of upcoming triggering content are shown

Content Pages

Warnings can be added to the content page or section header or in a box with an appropriate icon.

Approaches from Around the Globe

The following are examples of approaches other universities have used:

Other Terms Used instead of CW

  • Content Alert
  • Content Warning: Violence
  • Trigger
  • Warning: Graphic and Disturbing Scenes

Debate about Usefulness of Warnings

There is debate regarding the effectiveness of content or trigger warnings. While the warning may forewarn readers of potentially sensitive content, they may still have to engage with the content. In some cases, the warning does nothing to alleviate or prepare students for the subsequent distress (Sanson, et al, 2019). In some cases, an accommodation may be provided wherein the student affected could complete an alternate assignment, read on another topic in lieu of the potentially sensitive content, or be given grace to not attend any lectures where the content is being covered.

Including warnings does not seem to have any adverse effects on students, and warnings can be useful in helping individuals for whom certain content may be distressing enough to interfere with their learning. In most cases, students can then judge for themselves how they would like to engage with the material (e.g., to prepare themselves emotionally or to take breaks) or if they need to skip certain content. If needed, an instructor can suggest alternative content. It is also helpful to remind students about the supports available at the Student Wellness and Counselling Centre.
