Today on Scope Conditions: what drives discrimination against immigrants – and what can be done about it?

When social scientists have sought to explain anti-immigrant bias, they’ve tended to focus on one of two possible causes: the perceived economic threat that migrants might pose to the native born or the cultural threat driven by differences in race, ethnicity, or religion.

In a new book with Mathias Poertner and Nicholas Sambanis, our guest Donghyun Danny Choi, an assistant professor of political science at Brown, uses an innovative set of field experiments to test an alternative possibility: that the native-born perceive migrants as a threat to longstanding civic norms.

Could anti-immigrant bias be shaped by fears – often unjustified – that newcomers don’t share the same ideas about the meaning and practice of citizenship? Can misperceptions about norm-divergence be corrected? And are there interventions that can actually lead native-born citizens to adopt more cooperative behaviors across ethnic and cultural divides?

In their book Native Bias, Danny and his coauthors try to get at these questions using a wonderfully creative set of experiments, carried out across Germany shortly after the arrival of over a million Syrian refugees. You’ll have to listen to find out how the experiments worked – but for now we’ll just say that they involved dropping thousands of lemons on train platforms. 

We talk with Danny about how the team came up with their experimental designs, how they carried them out, and what they found. One of their most interesting findings is that native German women tend to be more accepting of Muslim female migrants who signal that they hold progressive gender norms. But we also push Danny on the implications of the book’s findings. The treatments in the experiments involve immigrants demonstrably signaling their adherence to dominant German values. Even if this signaling works to dampen discrimination, we wondered how exactly this kind of intervention can be scaled up to the societal level. We also talk with Danny about who the book is saying bears the onus of reducing discrimination: is it up to immigrants to “fit in” better or up to natives to examine their own prejudices?
