Testing a model of message sidedness: Three replications

Abstract
This experiment tested the results of a meta‐analysis of message sidedness (Jackson & Allen, 1987). The results are consistent with the prior meta‐analysis. Two‐sided refutational messages were more persuasive than one‐sided messages, which were in turn more persuasive than two‐sided nonrefutational messages. Testing the generalizability of this finding using 17 messages found consistent effects across the messages.
