Table 1. Modeled sets of behavioral rules and information required for each.

Rule	Description	Information used
“Uninformed”	If in one of the active states, give up (become disengaged) at a constant rate	None
“Oblivious”	If in one of the active states, give up more readily when transport is unsuccessful, and less readily when it is “successful” (see text)	Must be capable of measuring the “success” (i.e. extent of coordination) but not the direction of the majority relative to one’s own behavioral state.
“Informed”	If in one of the active states, and if transport is successful, give up readily if going the opposite way as the majority and less readily if going the same way as the majority.	Must be capable of measuring (i) extent of coordination and (ii) preferred direction of the majority and must compare the latter to one’s own behavioral state.
