Thank you so much for your thoughtful comment. It is important to consider the broader context within which one part of life takes place. One can wonder, for example, about the impact of dark stories on children who enjoy rich family support versus children who receive less support or worse. Following the events of 9/11, parents were encouraged to provide extra attention and reassurance to their children who were confused and anxious amid news coverage saturated with graphic content. Research has shown that emotional effects can persist, even throughout a person's life.
You remind our readers that a topic such as the lifelong impact of stories is not only complex, but also very difficult to research empirically.
