Subjects wagered an average of 4.22 confidence points per
round (S.D. 2.5). To see whether customization influences
DSS users’ confidence in their decisions, I fit a similar multilevel
regression model as model 4 above with customization
and recommendation quality as independent variables and the
number of confidence points wagered by the subject as the
dependent variable. This model showed no statistically significant
effect of customization on confidence in decisions.
