Fig. 5

The x-axis in this figure is common to two parts of Fig. 5 (5a and 5b). The numbers on the right of the points are group IDs from 1 to 25. a Distribution of sensitivities of confidence weighting best matched group answers for each group. The y-axis value indicates difference scores by subtracting error scores of group answers from that of confidence-weighted (CW)-Borda. Lower error scores reflect closer to the group decision. The x-axis value indicates inverse temperature k values. Higher k values reflect that the weight value of a higher-confident group member increases and that the weight value of a lower-confident group member decreases. b Distribution of performances of group decisions for each group. The y-axis value indicates error scores with group decisions. Lower error scores indicate better performance. c Distribution of utilization of resources of group decisions for each group. The y-axis value indicates utilization of resources with group decisions. Larger values indicate more use of the rank orders of individual group members for group decision-making
