Fig. 4: Efficient jury size in real-life settings.
We examined associations between the opinion homogeneity FMajor and anti-conformity tendency q in the three real-life large-scale social networks (Leskovec and Sosic, 2016). In all the three networks, FMajor converged toward a q-dependent specific value even when the initial FMajor was largely different (a). The convergence FMajor was negatively correlated with q (b). By applying such an inverse association between FMajor and q, we could narrow down Nefficient into 11.8±3.0 (c). These results imply a statistical mechanism, which avoids over-shrinking/expansion of the jury size in the real-life society (d).
