Abstract

Many studies have documented what listeners understand when uncertainty is communicated to them verbally. Yet we still know little about the factors that will influence speakers� choice of a probability phrase over another when they wish to communicate uncertain facts. Using a legal setting, we showed that the quantitative meaning and the directionality of the verbal probability chosen were affected by both the uncertain outcome�s numerical probability and its perceived propensity of guilt. The discussion of these results will focus on implications for the understanding of speakers� choices of verbal probability phrases and for risk-framing in legal contexts.
