Vicarious trauma and secondary traumatic stress describe psychological harm that builds up from repeated exposure to other people's suffering or to disturbing material. In moderation, the source is the violent, abusive, or graphic content reviewers see every day.

‍

‍Why it matters

The two terms come from research on therapists and other helping professionals, and they aren't identical. Secondary traumatic stress looks like the symptoms of post-traumatic stress, such as intrusive images, avoiding reminders, and feeling constantly on edge. Vicarious trauma refers to lasting changes in how a person sees the world, for example their sense of safety or trust in other people. Neither is a sign of weakness. Risk builds with the amount and intensity of exposure, so it's an occupational hazard employers need to manage, not a personal failing.

‍

‍How exposure can be reduced

The practical levers are limiting time spent on the most disturbing queues, rotating reviewers between content types, taking regular breaks, and giving easy access to counseling. Some research suggests that tools that blur images or show them in grayscale can lessen the emotional impact. None of these fully removes the risk, so teams also watch for early warning signs.

‍Commonly described warning signs

People often report intrusive images or thoughts, trouble sleeping, emotional numbness, irritability, withdrawing from others, and a growing cynicism about people. These can build slowly, which is why regular check-ins catch problems a person might not notice in themselves.
