From: How the wisdom of crowds, and of the crowd within, are affected by expertise

Fig. 2

MSEP of the inner (blue) and outer (red) crowds in Experiments 1 (a) and 2 (b) as a function of number of estimates. Note the different scales of the y-axes. The dots indicate MSEP averaged over set size; lower MSEP values indicate greater response accuracy. The solid lines indicate the population-level parabolic function, a/t + b, estimated from our mixed-effects models. The dashed lines indicate estimated crowd bias (i.e., b). The asymptotic advantage of estimating based on a crowd versus a single response (i.e., a) can be seen by comparing the dashed lines to the leftmost dot; this gap represents the effect size of crowd wisdom
