Abstract: Among the most researched solutions to social dilemmas is communication. Since the late 1950s, it has been well known that communication enhances cooperation in social dilemmas. This article reports a meta-analysis of this literature (forty-five effect sizes) and finds a large positive effect of communication on cooperation in social dilemmas (d = 1.01). This effect is moderated by the type of communication, with a stronger effect of face-to-face discussion (d = 1.21) compared to written messages (d = 0.46). The communication-cooperation relationship is also stronger in larger, compared to smaller, group social dilemmas. Whether communication occurred before or during iterated dilemmas did not statistically affect the communication-cooperation effect size. Results are discussed according to theory and research on communication in social dilemmas.
