https://www.psychologytoday.com/us/blog/words-matter/201808/do-trigger-warnings-help-or-harm Since the subject of "trigger warnings" has come up again (and there's been a bit of interesting discourse), this article should be enlightening.
First off, it's interesting to see a discussion about trigger warnings. Well, I suppose they've been rebranded as content warnings.
As far as I know, the science tends to show that people tend to underestimate their own resilience.
A very effective way to fight PTSD involves controlled exposure, such that a trigger will no longer be upsetting (and often, the trigger is not the scene but the precursor to the scene, such as someone standing there).
In any case, avoidance might work in the short term, however, it's not good in the long run.
The warning itself can also contribute to anxiety. It's particularly questionable whether it's useful in an educational setting.
One time, I saw a content warning on an article about legal policy, simply because it had to do with taking down actual child porn on the Internet (and the implications for online privacy and those other things we tend to talk about).
It didn't even really cover that subject at all. It was an article purely about legal policy. Is this not too cautious?
