Populism and Political Parties Expert Survey (POPPA)

Key takeaways:
– Radical right parties remain the most populist, followed by the radical left
– Nativism & left-wing economic rhetoric are strongest predictors
– Populism has declined since 2018, esp. among parties with weaker nativist/authoritarian profiles 2/2

Most of all: thanks to the 324 experts who were so kind to share their expertise with us - and with all of us (as this is a public data source.)

Have fun!

The project is a collective effort by Andrej Zaslove (Radboud U), @mauritsmeijers.bsky.social and @robert-a-huber.bsky.social. We are thank for for the amazing research assistance by Sanne Van Helmondt, Puck Overhaart, Victor Bouemar, Annika Püschner and Grace Steffens.

See for instance this item on 'democratic commitment'. The item asked experts to place the party on ranging from "priortizing own political gain" (0) to "priortizing democratic rules and norms" (10).

That produces this picture : (only radical left and radical right shown). 5/

In addition, we offer new items, measuring party traits with respect to democracy; climate issues; compromise; and issue salience amongst others.

NB: Some of these newer items are still under embargo, but those will become available for public use soon. 4/
