High-level descriptions of the three naive sociology models used in our studies

	Interaction term (probability)
Sociology (Interaction type)	Initiator P(init∣struct)	Recipient P(recip∣init)	Response (resp∣init, recip)
Authority (Orders)	Agents with more subordinates more likely to initiate	Agents subordinate to initiator more likely to receive Agents closer to initiator more likely to receive	Agents subordinate to initiator more likely to accept
Friendship (Invites)	Agents with more friends more likely to initiate	Agents in same clique as initiator more likely to receive	Agents in same clique as initiator more likely to accept
Friendship (Requests)	Agents with more mentors more likely to initiate Agents with more mentees less likely to initiate	Mentors & peers of initiator more likely to receive Agents closer to initiator more likely to receive	Mentors & peers of initiator more likely to accept

(see Supplementary Information for equations). Each row corresponds to one of the three sociology/interaction types (from top to bottom: authority/orders, friendship/invites, mentorship/advice requests), and each column corresponds to one of the three phases of interaction represented in our model. Within each cell, we list the relevant features of the social structure and how they influence the likelihood of different interactions.
