Why are people who make questionnaires so bad at making questionnaires? It's baffling. This post is particularly glaring but I always find stupid errors or assumptions like this.
Where i live, none of the forms to apply for a flat ask only allowed questions. The respective agency even provides a summary, what questions are not allowed (like gender, religion) because discrimination potential but all ask at least two of them.
Unless you're very self-aware, one requires actual training and practiced mindfulness to break free from that in all endeavors. There's also some lack-of-the-outside-world going on too - one would need to have at least thought about world experiences apart from one's own, to consider alternative possibilities.
