"Trigger warnings are customary in some feminist and other spaces. They are designed to prevent people who have an extremely strong and damaging emotional response (for example, post-traumatic flashbacks or urges to harm themselves) to certain subjects from encountering them unaware. Having these responses is called "being triggered.
Content which is widely agreed by feminist blogs and fandom writers to be warned for:
*graphic descriptions of or extensive discussion of abuse, especially sexual abuse or torture
*graphic descriptions of or extensive discussion of self-harming behaviour such as suicide, self-inflicted injuries or disordered eating depictions, especially lengthy or psychologically realistic ones, of the mental state of someone suffering abuse or engaging in self-harming behaviour
*discussion of eating-disordered behavior or body shaming
These are more extensive than the mainstream media observes. Of these typically only suicide is elided, understated or warned for by the press. In some countries television shows or movies might be preceded by an indication of the nature of violent or sexual content. Professional fiction does not typically warn for any such content on bookjackets or in reviews or similar.
Some people argue that even factual, dry mentions of the above subjects should be warned for. In some sections of Media fandom there are also arguments that warnings should be made for:
*depiction or discussion of violence
*depiction or discussion of particular kinds of consensual sexual activity (BDSM, homosexual encounters, heterosexual encounters...)
*depiction or discussion of any consensual sexual activity
*depiction or discussion of discriminatory attitudes or actions, such as sexism or racism
A trigger warning usually takes the form of some emphasised (usually bold) text starting with a warning phrase (such as "trigger warning," "content warning," or just "warning") and describing in broad terms the upsetting nature of the content. The actual triggering content might be below the warning or hidden in some way requiring readers to click through.
There is no consensus on the 'best' way to word a trigger warning so that it accurately describes the potentially-triggering content without becoming a trigger itself. [bold]The phrase "trigger warning" may itself be triggering to some trauma survivors.[/bold] People can also be triggered by warnings that include too much detail. Warnings with very general language, such as "Warning for a graphic depiction of sexual violence" or "Content Warning: disordered eating" are less likely to trigger readers than warnings that include specific details about the triggering content.
