In my experience doing research, this question should go *at the bottom*. Why: A basic 101 thing one learns in Market Research is that personal questions _always_ go last. So, if you want to ask an interviewed person if their answers were honest, researchers should be placing them last, towards the end of the questionnaire. But, this only works if the questionnaire is oriented towards asking first impersonal questions, then more personal ones. As another commented said: This is a lot of work. Doing research, asking people questions, gathering and then analyzing data is no walk in the park. It's sad that this happened. And, most important of all: Always being honest, no matter what the results are, even if you don't like them.
