Dimension reduction: (a) a PCA analysis of the top items of all question groups (PC axis 1 explained 13% of the variation and PC axis 2 explained 12% of the variation) and (b) characteristics of the main respondent groups from a k-means cluster analysis. Points on each axis represent the mean value for people within each group (separated by different colours) scaled between the minimum and maximum values. Table S1 gives a fuller description of all question items.
