David Campbell, a thoughtful writer on photojournalism, has just published a draft of one of his most recent papers, “The Myth of Compassion Fatigue” (pdf). There’s a summary of the paper’s main points on his blog. The paper addresses the origins of the idea of compassion fatigue, Sontag’s own reversal of her original thesis, current thinking about compassion fatigue, and, most importantly, a look at what sort of evidence might indicate that compassion fatigue is a problem.
