I’m going to give an example of getting triggered myself. First however warning! I will mention a phobia you may not have heard about. Do not, I repeat do NOT jump to googling it before you read my message. It’s visually triggered and googling may well reveal you have it, in a way ranging from irritating to painful.
So, I’m trypophobic (this is the term I recommend you to not google). Trypophobia is the phobia of holes or more precisely of clusters of holes. Some sufferers get it from very many things and patterns, while for others it’s just certain kind of holes or pictures of them. Many get a bad reaction from viewing a stack of straight pipes from the end do that they see into many of pipes at once, and/or honeycombs. For me it’s only some organic kinds, and geometric or regular holes don’t do anything.
Interestingly enough, the existence of this phobia was not known of until well into the 2000’s when people happened to discuss it over the internet and discovered they are not the only one who gets this weird reaction. Unfortunately nowadays it’s hard to learn anything about it because many sites seem to consider it amusing to adorn pages telling about it with pictures that cause it to maximum amount of people.
It sounds ridiculous. I find it ridiculous, stupid, idiotic! I can extremely easily see how it seems like a made up thing, if you don’t have it. Yet I can’t help it. My son also has it. My husband was sure I had told my son about it and therefore “made” him get it, but I hadn’t! The intensity varies, sometimes he gets uneasy if there is e.g. foam in his drink or food, although mostly that kind of thing is ok. In my own case, if I get properly triggered, I’m a lot more sensitive for a couple of weeks.
I had followed a popular science page on Facebook and one day they put up a post about it. The preview picture of that post was of the thing that is best known to cause the reaction in many trypophobics. So, I had the picture thrown in front of my eyes and what has been seen cannot be unseen. So I got an... attack? Reaction? That was strong uneasiness and disgust but still manageable. I was stupid enough to think the damage was done so I can read the article. Not true. They had managed to come up with something A LOT worse (by photo manipulation, while the original well-known trigger was a photo of a natural thing). I had basically a panic attack, and went into a state where I was on the edge of a panic attack for hours. I couldn’t sleep for several nights, I needed to scratch incessantly, to put it shortly was awful. I get mild reactions now writing about it (which I why I can’t mention what the thing was).
I had had a respect for trigger warnings before, but had I not, this experience definitely taught me what it means to get triggered. For other people and other phobias or trauma it can of course be a lot worse. So, what am I trying to say? Firstly, a thing that seems trivial or impossible as a trigger to you may be serious for someone. The brain is WEIRD. Secondly, there is no way anything can include the warnings for everything that may trigger someone, because there is just no way to know. Even the person getting triggered maybe doesn’t know in advance. So you can’t be perfect. However you can and should try!
So what can we do? Firstly, try and be predictable. There can be monsters in your horror comic, however don’t put monsters into the Highschool Musical (without warning that is). Secondly, try and give a general idea of the content up front. Thirdly, if someone tells you what triggers them, please respect that. It doesn’t mean you can’t include / present / show etc that thing, but give the person the choice about whether they can take it or not. The warning is specifically meant as a tool to be able to cover the subject or issue in a way that is safe for everyone, and not as a label of “you should not be dealing with this thing because it may trigger someone”.
Furthermore, do not use a known trigger for “fun” like many of the articles about trypophobia do. That is ducking rude.
As with anything, there probably are people who try to use a concept for their own advantage, or otherwise misuse it. Such as some students demanding that an issue is not covered in a course because they don’t like it, but call it getting triggered to make it sound serious. The fact that such people exist, doesn’t render the concept and the need for the warnings null and void. Also it doesn’t give people (in this case, the professors) a free pass to ignore legitimate needs of warnings.
Oh and on the subject of “real life doesn’t have trigger warnings”. Indeed. I think this is a reason for the warnings p, not against them. People are already forced to deal with their issues in situations where it’s impossible to get the warning (such as encountering a spider in nature, or driving past a stack of pipes). They already have to strain themselves with the phobia/ trauma / issue. Why should you force them to strain even more?
