networks + persuasion

communication network

a social structure made up of a set of actors and the ties between those actors

communication networks are comprised of…

nodes

nodes

we’re nodes that communicate with other nodes

gatekeeper node

a node that controls the flow of information between one part of the network and another

bridge node

node that connects multiple groups, member of 1+ groups

liaison node

connects 2 groups without being a member of either group

isolate node

no or very few links

star node

highly connected node, highly central to the network

centrality

importance/prominence of a node, typically based on number of ties

nodes list:

• gatekeeper

• bridge

• liaison

• isolate

• star

tie multiplexity

the number of separate connections between any 2 actors

tie strength

strong and weak

network density

measure of proportion of actual connections relative to the total possible connections in a network (high/low)

homophily

degree of similarity between people

heterophily

degree of difference, good for new information

network studies teach us transmission of

• information

• norms

• behavior

multiplexity

the ability to communicate via multiple communication channels

media multiplexity theory

the more communication channels used between 2 individuals, the stronger their relationship
