I came across a phrase for a type of question which is designed to discover someone's religious background, particularly in the context of sectarianism and divided societies but can't for the life of me remember it.
For example, if you are in Scotland and I ask you what football team you support, that may reveal your religion. Or in N.Ireland, if I ask what school you attend, likewise that may do the same.
It's like a 'veiled question' only that's not the term I'm looking for. Any help appreciated. I've a feeling that the second part of the phrase is (question) as in, a INSERT TERM question, but not 100% sure.

A probe for seeing if someone belongs to a particular group can be called a shibboleth. Wikipedia link
