Every time this worry comes up (www.ft.com/content/d419...) I post some Landy et al. (2018). People just answer questions about proportions (of anything) in a rather particular way. So I think it's unlikely that what they are being asked about is as important as you might expect it should be.

issues, and the results on immigration are
sobering. UK respondents dramatically overestimate how many immigrants there are and how many of them are Muslim. They overestimate what proportion of immigrants are from north Africa by a factor of 10, and from the Middle East by a factor of two, and underestimate how many are from North America. Respondents underestimate how many are Christian, and also underestimate the education levels and employment status of immigrants relative to the UK-born population. These misperceptions are not unique to the UK - they are common in rich countries.People seem to answer proportion questions in log odds space, not probabilities. And when you know that, there seems a lot less substantive interpretation worth doing.

Impassioned plea for more mixed-methods research (quant & qual) from @timharford.ft.com "The hard data is never as eloquent as a good story. Humboldt would measure the cactus but also sketch it; drag his barometer up a volcano, but spin a yarn about the epic climb." www.ft.com/content/d419...

I'm very happy to share that I'll be joining the Department of Political Science at UNC Chapel Hill as an Assistant Professor this fall. I'm excited for this next chapter and will always be incredibly grateful for my amazing experience at Stony Brook.
