Fig. 2: Each dyad converges to a specific stable strategy on the cooperation–competition spectrum.

a Moving average (1 min window) of the fraction of single targets (FST) for three representative dyads. (b) Mean absolute deviation from a dyad’s eventual stable strategy as a function of time (shaded band represents 95% confidence interval). After 14 min, all 58 included dyads have converged to a stable FST. c Distribution of the stable FST across dyads, which we categorize into three groups: largely cooperative, preferentially collecting joint targets (FST ≤ 0.1, n = 14, Supplementary Movie S2, YouTube, OSF), largely competitive, preferentially collecting single targets (FST ≥ 0.9, n = 14, Supplementary Movie S4, YouTube, OSF), and an intermediate, performing mixed collections (0.1 < FST < 0.9, peaking around ≃ 1/3, n = 30, Supplementary Movie S3, YouTube, OSF). Colors along the vertical axis represent the stable FST of each dyad, from brown to cyan. Here and in (d), the non-circle markers (plus, diamonds) indicate special strategies described later. d First-minute FST vs stable FST (from 10−40 min). Most dyads decrease their FST (i.e. become more cooperative) over time.
