There are individuals who actively enjoy or even seek out this kind of graphic content. I never understood why they aren’t recruited more as their unique talent would probably help them excel in this kind of career. I remember on Reddit someone was writing about how he gets “gore boners” from this stuff. Why mentally abuse normal minded individuals for this work? Obviously they can’t handle it and probably go home everyday shaken.

If the work has the potential to cause a mental disturbance then you want the baseline to be fairly close to normal. If the guy that gets gore boners is tasker with looking at disturbing content all day and then had some sort of mental break it would probably be a lot worse than what a normal person might end up doing.

I believe this is a central premise of Peter Watts' Rifters series, related to submarines and astronauts and such, wherein "broken" people are considered more resilient to heavy shit than the equally capable/trained people who may more likely break when faced with said heavy shit.
