Linguistic threat: Vote choice, linguistic cues and support for official bilingualism in Quebec

In Canada, federal institutions must provide governmental services to all citizens in the country's two official languages: French and English. This paper uses a survey experiment to test exposure to written English as a determinant of support for official bilingualism in the French‐speaking province of Quebec. The data emanate from an exit poll conducted in two Quebec electoral districts during the 2019 Canadian federal elections (n = 430). Results suggest the existence of heterogeneous experimental effects depending on vote choice. Indeed, Bloc Québécois voters—the federal party most strongly supportive of linguistic rights—are disproportionately supportive of institutional bilingualism when randomly exposed to written English on the survey questionnaire. These results are robust to the inclusion of socio‐demographic and attitudinal control variables, including support for Quebec independence. Our paper bolsters causal claims about the contextual determinants of in‐group favouritism and cultural threat in divided societies.
