Do Political Beliefs Drive Environment Selection?

Scholars interested in understanding if and to what extent social environments influence individual political behavior are plagued by the reality that individuals construct their social environments. Though there is acknowledgement that this construction is determined by homophily – likes associating with likes – the extent to which political beliefs drive environment selection is yet untested. This paper seeks to understand the extent to which political beliefs inform individuals’ decisions on which social environments to select into. To do so, I follow individuals as they select into social environments across their first year in a university setting – first contacting them before they are embedded in a new social environment, tracking their selections into friendships and groups, and observing how their attitudes change over a year and a half period. Results demonstrate that political beliefs can be significant predictors of selection into non-political social contexts, especially for those with the strongest beliefs about politics.
