Gotcha type interview questions with a single "trick" that you either get/have seen before or don't provide terrible signal imo.
And the specific question can lead to a conversation, which may "reveal" the answer (obviously, I don't know whether this is the correct answer), but at the very least it reveals whether the interviewee thinks about selection bias, among other concerns.
Huh? "Gotcha question" doesn't imply it's a single question that's not part of a series of questions. A "gotcha question" is simply a question designed such that it's very easy to respond with something that sounds bad or is incorrect.
