The influence that two time series impose on each other is detected by cross-corelation plots. If no causal relation exist between them, the cross-correlation function is symetric and centered on 0. The existence of a causal relation between the two series generates an asymmetry in the cross-correlation function38. Moreover, the direction of the deviation along the ordinate axis provides the direction of the correlation (see Supplementary Method for more details). Here, asymmetry and the direction of deviation in the cross-correlation function between the P strategy and the M strategy as well as between the P strategy and the S strategy, means that the P strategy has a negative effect on monogamous individuals and a positive effect on sneakers. In contrast, the cross-correlation function between the M strategy and the S strategy shows that the M strategy does not affect the allele frequency dynamic of the S strategy. At the global scale of the RPS game, the P strategy appears to drive the game.
