Collective chemistry. Sudden appearance of a large clump of correlated objects, which is referred to in the physical and chemical literature as a gel, or in the network science field as the giant connected component (GCC). This is shown for different values of the average aggregation probability F. F depends on the initial composition of the population (i.e. distribution of \({\overrightarrow{x}}_{i}\) values) and the grouping mechanism (see SI Sect. 2.2, Eqs. (1), (2)) and hence embodies the collective chemistry. For a uniform initial composition, an \(F\) value of 1 indicates any individual could fit into any group, 2/3 indicates grouping via homophily, and 1/3 indicates grouping via heterophily. The horizontal axis time values are scaled so that \({t}_{onset}=N/2F\) appears as \({t}_{onset}/N=1/2F\), e.g. onset time for \(F=2/3\) appears as \(1/2F=3/4\). The accompanying mathematical theory is described in full detail in Sect. 2 of the SI.
