The Electoral Appeal of Symbolic Class Signalling Through Cultural Consumption | British Journal of Political Science | Cambridge Core The Electoral Appeal of Symbolic Class Signalling Through Cultural Consumption - Volume 55

Really happy to see my work with @dweisstanner.bsky.social published with @bjpols.bsky.social. In this letter, we look at symbolic class signalling through cultural consumption and how effective it is across voters of different parties.

How should we study party polarization in Europe?

Using @chesdata.bsky.social and @cses.bsky.social data, we demonstrate the value of our multidimensional approach and its ability to better predict mass partisanship

We introduce the *effective dimensionality* of a political space, and use it to analyze multidimensional polarization

โœ… Simple, intuitive, and easily extended to any type or number of dimensions

Main point ๐ŸŽฏ

-- Dimensions can collapse into 1D polarization (see PT)
-- Dimensions can be orthogonal and produce 2D polarization (see NL)

๐Ÿšจ Reinforcing vs. cross-cutting polarization have different consequences for democracy!

โš ๏ธ Left vs. right polarization frequently underestimates party differences, especially on cultural issues

โš ๏ธ Summing up individual polarization scores assumes dimensional independence

โžก๏ธ We need an alternative approach!

We argue that left vs. right polarization is ill-suited to capture contemporary party conflict

European party systems are complex, fragmented, and structured by multiple ideological divides (e.g., economic + cultural)

โ€ผ๏ธ O, Canada is now in CHES!

The data include party position estimates for federal parties in Canada + parties in Ontario and Quebec. It's also super easy to combine with other @chesdata.bsky.social data to compare positions with positions of parties in other countries!
