Responses shown on a percentage scale where 100% represents complete agreement with the upper anchor label in Extended Data Table 1 and 0% represents complete agreement with the lower anchor label. Three distinctive response patterns are highlighted in lighter colour: extreme responses whereby participants moved the response slider all the way to 0 or 100%; and responses of exactly 50%, which necessitated moving the slider off the midpoint where it was initially, and then purposefully moving it back onto the midpoint (leaving it untouched on the midpoint would have prevented them from continuing to the next trial). Thus, for instance, the middle bin for theme ‘ideal rules’ contains some responses precisely at 50% in lighter blue and some responses near 50% in darker blue. Similarly, the left-most bin for theme ‘rational self-interests’ contains some responses exactly at 0% in light blue and some responses near 0% in dark blue. We highlight these distinct response strategies to emphasize the connection with regression models that quantify bimodality, extreme responses and midpoint spikes in Supplementary Table 1.
