Proportion of choices of the option with the higher EV, i.e., decision quality, depending on numeracy. (a) The relationship between numeracy and decision quality across all choice problems. (b) The relationship between numeracy and decision quality separately for risky.better problems and safe.better problems. Each subplot includes the posterior mean estimate and corresponding 95% posterior interval of the β-coefficient representing the link between numeracy and decision quality, obtained in the Total Effect Model for the respective (sub-)set of data (see also Table 2).
