Extended Data Fig. 6: Proportion of human interactions activating only matched and real games in the same cell.

Each bar corresponds to a pair of corresponding matched and real games. In each bar, we plot the proportion of relevant interactions (state-action traces) that are unique to the matched game (blue), unique to the real game (green), or shared across both (purple). A few games (with the bar mostly or entirely in purple) show high similarity between the corresponding games — under 25% (7/30) share more than half of their relevant interactions. Most games, however, show substantial differences between the sets of relevant interactions, with some showing a higher fraction unique to human games and others to matched model games. The average Jaccard similarity between the sets of relevant interactions for the matched and real game is only 0.347 and the median similarity is 0.180 (identical games would score 1.0, entirely dissimilar games 0).
