This study seems to be pretty limited regardless of how it's carried out.<p>People seem to be hung up on the <i>new</i> term "trigger warning" when we've had <i>content warnings</i> since time immemorial.<p>Nobody seems to be writing the articles on "efficacy" of movie ratings, or putting "18+" labels on content. We, as a society, understand that not all content is suitable for all audiences... when it comes to sex, and sex only, it seems.<p>Then there's the issue of <i>trust</i>. Any source that gives a heads-up of what's coming and <i>doesn't</i> spring 2girls1cup on you without a warning is going to be more trusted than the one that <i>does</i>.<p>Why is that even a question when the same principles applies to content <i>other</i> than an unclothed female nipple or (gasp) genitals? Is it so hard to make the leap to other subjects, such as vivid depictions of rape and violence?<p>Why isn't it common sense that, regardless of studies of "efficacy", giving a heads-up about shit that some people in the audience might not want to see <i>unprompted</i> is, like, <i>polite</i>, and is universally a <i>good thing</i>?<p>It's frankly exhausting to even have these discussions, again and again. Trigger warnings are about <i>not being an asshole to the people who choose to listen to you</i>.<p>The effect is they might choose to listen to you <i>again</i>, because you're not a dick. End of story.<p>_______<p>TL;DR: the study focuses on nebulous "effects", whereas they should be looking at bounce rates.
