“The more official, the less I believe”: Using focus groups to explore public opinion formation in politically polarized contexts

Abstract Introduction Public opinion studies have traditionally relied on survey analyses. However, a qualitative approach is needed to address opinion formation's multidimensional and contextual nature. In this study, we argue that focus groups are a technique that addresses these unique challenges. Methods We test this argument by looking at the case of Chile, a country marked by a streak of eight elections in three years, including two national referendums for a constitutional proposal. In this politically polarized setting, and over the course of the latter election year, we conducted 10 focus groups comprising a diverse sample in terms of gender, age, socioeconomic status, and occupation. As participants shared news diets, political views, and values, data suggest a tendency to independently verify information regardless of the source, and highly influenced by their close ones. Results From a methodological perspective, our findings show that focus groups enable the assessment of the context‐situated opinion formation process, reveal emerging themes, and promote open discussion. These results also reflect the multifaceted nature of public opinion formation in a dynamic media landscape and can inform other countries undergoing a crisis of institutional legitimacy.
