When Does Diversity Trump Ability (and Vice Versa) in Group Decision Making? A Simulation Study
Figure 1
Results from Study 1: group size.
Note that there was no effect of group size on a take-the-best (TTB) group's performance in this set of simulations, because the group was assumed to be totally homogeneous. MIN-1, MIN-5, MIN-15, and MIN-100 stand for a minimalist group with 1, 5, 15, and 100 agents, respectively. Environments differed in their distribution of cue validities: LD, large difference; MD, medium difference; SD, small difference; ND, no difference. PC: Percentage correct.
