Continual rapid news updates and social networking tools like Twitter can cause further indifference to human suffering, some studies show, reports CNN. The media give too little time for the brain to digest violence and suffering in one story before they bombard the viewer with the next and this can have implications on their morality, according to a University of Southern California study. Twitter sees itself as a solution to information overload because the viewer can step in and out of the information flow at will, according to CNN.
