Testing the persuasiveness of evidence: Combining narrative and statistical forms

Abstract

This study provides an experimental test for the conclusions of the Allen and Preiss (1997) meta‐analysis that statistical evidence is more persuasive than narrative evidence. This investigation extends that finding to consider the case where a message combines statistical and narrative evidence to determine if a combination of evidence is more effective than a single form of support. This investigation using 15 messages and 1,270 participants finds that a message combining narrative and statistical evidence is more persuasive than a message using either narrative or statistical evidence alone.
