I think if the person is smart enough, they’d know why you are asking and they’d give you the answer you want to hear. They’d figure out you aren’t asking for the sake of it but trying to figure them out as a person so they’d be smart enough to concoct attractive answer. These kind of questions only work if we assume everyone is honest and up front and straight forward. But then there will be no scammers and no manipulators but it’s just not the case
