The stability of divided societies is an important and recurring concern in political science research. It has been suggested that distinctive socialization processes in the different regions of divided societies will lead to diverging trends in public opinion. Therefore, we investigate trends in public opinion on key political issues and attitudes in three divided societies: Canada (Quebec), the United Kingdom (Scotland) and Spain (Catalonia). Using over two decades of survey data, we show that these distinct communities indeed have a particular ideological profile but also that there is no indication these differences become larger over time. In other words, we do not observe any evidence for an increasing lack of public opinion coherence in these divided societies. We conclude with some observations on why divergence could not be observed at the level of public opinion but might still be present at the level of party elites.
