Title: Deep Divides
Description: This dissertation examines three different subjects underpinned by one common approach— the survey experiment—and, broadly, one common aim: to better understand heterogeneity in public opinion in the United States and Canada. Specifically, it focuses heterogeneity as it relates to minorities and the cultural dynamics that emerge in multiracial and multiethnic countries. Contexts with diverse racial and ethnic compositions, diverse immigration and equity policies, and complex sociohistorical lineages are bound to be underpinned by deeply fragmented attitudinal dynamics. Yet only recently has research taken a deep dive into what the contours of this fragmentation might look like. As diversity increases in the West and cultural complexities deepen, understanding heterogeneity in public opinion toward and among different cultural, racial, and ethnic groups will become increasingly pressing. Luckily for the research community, the ability to study such heterogeneity is increasing as well. Fielding large-scale surveys has been facilitated by both the vast penetration of the Internet in the 21st century and the explosion of online marketplaces that allow researchers to buy survey respondents relatively cheaply and quickly.

This dissertation exploits these contextual developments to field three online survey experiments among a total of 40,000 respondents in Canada and the United States.
