Previous research has demonstrated that opinion leaders consistently have more information on the topic of their leadership than do non-opinion leaders. This study tested two theoretical explanations for this phenomenon: selectivity in exposure to information, and differential attention to information. The results provide support for both explanations. Opinion leaders were found to acquire more information than non-opinion leaders under conditions of both voluntary and forced exposure to a mediated message. Both opinion leaders and non-opinion leaders acquired more information under forced exposure than under voluntary exposure.
