After 4 pages of unrelated marketing research questions I've closed the page.
Sorry, I think they're called "demographics"?
Demographics are my age and gender, not my tablet and interest in specific products. It's not very hard to see what you did there...
I'm sorry, I really don't understand what you think our intent was. The interesting, more topical questions need to be crossed with data about WHO answered them; data isn't all that useful without the added context. Most media studies you see written about on the internet or elsewhere report on things like, "smartphone owners were more likely to desire [x]," or "people who use multiple platforms to get their news tended to think [y]," or something similar. Asking which devices someone owns is just meant to make the study data more informative, not trick anyone. Understanding your basic audience profile is an important part of nearly all research. We understand if you're not comfortable answering those questions, but I wanted to clarify that they're entirely commonplace, and we meant nothing tricky or nefarious by asking them.
Additionally, it's a non-client, self-sponsored study. We never ask about your interest in specific products. We may ask about your interest in general kinds of experiences or interactions, though.
