Reducing intergroup prejudice and conflict: a commentary.

This commentary describes an alternative conceptual framework for interpreting the effects that E. L. Paluck (2009) found in evaluating a public education radio drama in Rwanda. The radio drama included information about the origins and impact of violence and the avenues to prevention and healing, with the aim of preventing new violence. In addition to comparing theoretical perspectives and their practical implications, the commentary addresses the spread of effect through public discussion, the program content, the participants' past experience, and measurement issues shaping the impact of the radio drama.
