Justification Explicitness and Persuasive Effect: A Meta-Analytic Review of the Effects of Varying Support Articulation in Persuasive Messages.
O'Keefe, Daniel J.
Argumentation and Advocacy, v35 n2 p61-75 Fall 1998
Discusses research evidence concerning the persuasive effects of three variations in the articulation of an advocate's supporting argumentation. Finds that greater explicitness in identification of the sources of information and in the completeness of an argument significantly enhance persuasive effectiveness and perceived credibility; greater quantitative specificity has no significant effect on these outcomes.
