The need to “put a face” on a humanitarian crisis and give it individual particularity is premised on a well-established phenomenon: As the numbers of a group experiencing suffering increases, the level of compassion felt for that group typically decreases. However, the mechanism behind this apparently counterintuitive dynamic — declining compassion as the level of suffering increases — has long resisted understanding.

As Internet search engines have become increasingly integrated into the way people locate, use and define information, concerns have been voiced over the impact this digital “crutch” may have on the lucidity and richness of human thought.
