Copying this question from Academia.Stackexchange.
Trying to do my research on trust and political polarization relationship, but my analysis section contradicts the theoretical. My dependent variable is polarization, independent - trust. I assume that the increase in the ingroup trust and the decrease in the outgroup trust will strengthen the political polarization (affective one, in particular). It is based on the social capital theory by Fukuyama, Putnam; political polarization theory by Iyengar, Moris, Fiorina, Druckman.
But my regressions outputs neither confirms this assumption, nor show the significance. I use self-collected survey data, N = 375.
These questions are mostly for political and social scientists.
Am I wrong in the theoretical assumption? Are there any conventional theoretical findings on trust-polarization relationship? Are there any more research on this topic that provide consistent trust-polarization theoretical nexus? What are the most suitable refereneces for this research?
