However, it is not always clear what types of data representation induce the most trust and which individual variables influence this. Previous studies have shown that there are trust differences between numerical and verbal representations as well as different uncertainty levels. Other research suggests that education level may be related to trust while research on numeracy and graphical literacy (GL) implies a potential relationship. Numeracy and GL have been reported to have a moderate correlation. Furthermore, trust is theorized to subsist of the related but distinct concepts of trust in number (TN) and trust in source (TS). To investigate these topics, participants were invited to a questionnaire study presenting an uncertainty scenario and assessing their trust as well as individual variables of numeracy, GL and education. Factors of different uncertainty levels, formats and education levels were used to create nine conditions that assessed whether the factors influenced trust. Results showed a small positive correlation between GL and numeracy. A positive moderate relationship was found between TN and TS. Moreover, results displayed a significant difference in TN between verbal and graphical uncertainty communication. Lastly, education was highlighted as a possible predictor of TN. Findings highlight education as a variable related to TN and strengthen the position that trust should be subdivided into TN and TS. Because of theoretical inconsistencies in our findings, more research has to be done on the effect of uncertainty level, format and education level in uncertainty communication.Show less
