Or if your goal is to not hire irritating smart-arses. It seems a way to filter candidates on ideology. You can't get away with asking if people believe in god or climate change or affirmative action or abortion rights. But a question like this prompts people to bring up any strongly held beliefs on sensitive topics themselves (sensitive topics are where you find your views are contrarian). Once the topic is raised, your unconscious biases do the filtering even if you are not doing it deliberately 'to ensure a good team fit'.
