 Johnston makes easier to understand social parallels that can be better understood by the layman.He explains these models as (1) I talk with them and vote as they do; (2) I want to be like them so I live with them; (3) I live among them and want to be like them; (4) what I observe around me makes me vote with them; and (5) they want me to vote for them here.Cox, in a similar attempt to understand the neighbourhood effect, attempted to define how people interact.
