Abstract
It is solid advice to employ more messages in one’s experiments when conducting research on message variables’ effects. The question is how many messages should be used? And what characteristics should these messages have? Compared to the insights and guidelines available for the selection mode and number of participants when aiming to generalize to a population, such insights and guidelines are sorely lacking when aiming to generalize over messages.
