Extended Data Fig. 7: Behavioral archetypes and β-value distributions in simulated social triads.

(a) Distribution (mean and individual data) of β-values across the three behavioral archetypes—Worker, Scrounger, and Storer—in simulated triads composed of either three high-β males (N = 1000 triads) or three low-β females (N = 1000 triads). (b) Distribution of the Worker-to-Scrounger β-ratio across male-only triads. The distribution is centered around 1 (mean = 1.007), indicating only a minimal but statistically significant bias (p < 0.001). (c) Q-learning simulation of three e-mice with two low-β individuals (females, β ∈ [0, 0.25]) and one high-β individual (male, β ∈ [2.25, 2.5]). (d) Proportions of Worker, Scrounger, and Storer archetypes as a function of sex across 1000 triads, revealing sex-dependent specialization patterns. (e) Distribution (mean and individual data) of β values per archetype (Worker, Scrounger, Storer) in mixed triads, highlighting β differences in value-based behavior. (f) Distribution of archetypal compositions per triads, grouped by β value (low vs. high).
