This paper discusses the issue of possible reporting bias in media-based violent-event data and its relation to the role of communication technology in fostering collective action. We expand the work of Weidmann (2016), presenting several sensitivity analyses to determine the degree to which reporting bias may confound the relationship between communication technology and violence in a recent study that relies on event data for Africa. We find no strong evidence that suggests results on the positive relationship between communication technology and collective action in the study by Pierskalla and Hollenbach (2013) are wholly an artifact of reporting bias.
