Abstract

Widespread acknowledgement of the weaknesses of null hypothesis significance testing has led to correspondingly greater appreciation of the central role of effect size estimation in social-scientific research. But in the context of message effects research, it is easy to confuse an effect size—a quantitative representation of the effect of a variable on an outcome—with the size of the effect of a message on an outcome. Illustrations of this misunderstanding are offered, its unhappy consequences specified, and remedies discussed.
