Post a favorite econ paper: Lichter et al. (2021, JEEA) @sigginho.bsky.social

Regions with higher Stasi spy density in East Germany still show lower trust, lower incomes, higher unemployment, and less entrepreneurship decades after reunification.

Mein Status als „Person mit Migrationshintergrund“ ist ziemlich offensichtlich. Da man es mir (abgesehen vom Namen) aber kaum anmerkt, gehe ich oft genug als „deutsch“ durch. Und auch wenn mir persönlich das ziemlich egal ist, weil ich kein Bedürfnis habe, als „deutsch“ oder „polnisch“...

AI-generated ‘participants’ can lead social science experiments astray, study finds Data produced by “silicon samples” depends on researchers’ exact choice of models, prompts, and settings

A lot of psych is already conducted with online convenience samples & ppl are probably excited about silicon samples bc it would allow them to crank out more studies for even less 💸

How about we reconsider the idea that sciencey science involves collecting own data.

Farmers (are expected to) fulfil diverse economic, environmental, and social roles or functions. Yet the relative importance of these functions remains contested both within farming communities and in the broader society. Understanding how farmers prioritize these different functions as a reflection of their role identity is crucial, given the increasing recognition of the importance of identity as a determinant of farmer behaviour. We frame this aspect of farmer identity in terms of multifunctionality, a common lens for analysing the performance of agriculture relative to societal demands. However, while this concept is often used with an ecological focus, our study builds on a broader interpretation that encompasses the full range of social, cultural, economic, and ecological functions. Furthermore, we focus on the roles farmers themselves would like to play when looking 10 to 20 years into the future. We apply Q methodology to see how farmers from Eastern Germany prioritize among 71 societal functions. We use the Q sorts and qualitative data to derive and characterize a typology of three narrative perspectives. The results demonstrate the breadth and heterogeneity of farmers' role identity, and therefore the need to go beyond a narrow focus on ecological roles or functions.

🌍Do all nations believe they’re superior—or do some feel inferior?

Western social sciences claimed the first. But Fanon & Memmi argued colonization by the West left many in the Global South with colonial mentality—internalized oppression.
