Mean knowledge (left) and fears (right) regarding organ donation across time and as a function of the humorous treatment for Study 1 (top) and Study 2 (bottom). Knowledge (sum ranging from 0–7) and fears (mean ranging from 1–7) were transformed into POMP scores (percentage of maximum possible scores, Table 1, ranging from 0–100%). Fear scores were re-coded, so higher scores mean less fear/more correct knowledge. Fear and knowledge items comprise the same content, but were framed either as knowledge or fears. Interestingly, mean percentage correct was higher when the items were framed as knowledge (left) instead of fears (right). Both studies show that humorous interventions lead to fewer fears (right). Error bars are 95% CIs. Numbers indicate n per group.
