Some guy on the street asked me if I knew where the nearby salad restaurant was. There was only 2 ways this could go. Either he wanted a salad for lunch. Or, as you suggest, he was testing me. Was I apart of this fabled salad group or one of the forsaken "others"? The pressure was on to say the least. I don't normally believe in a higher power, but I said a quick prayer for help to get me through this challenge. I gathered all my strength and told him "just a block that way" as I pointed down the street. Now, I could only wait for what felt like a millenia. Finally, he let slip the words "cool. Thanks" as he headed in that direction. I think i passed his nefarious test. But the only thing I'm sure of is that I barely made it out of there in one piece.
Edit: originally, the comment I replied to said that no question was innocent
They're linked aren't they? If someone asks you a question they're asking for why you hold a particular opinion, therefore simply by providing detail you're defending yourself, or at least the opinion you hold.
To answer the real question: "Everyone lives just as full a life as you, they think just as deeply as you do. Sure, people are brand loyal and don't think about things for themselves sometimes. But you, Mr. People Are Sheep, do the same thing, just in other areas of your life."
If the question seems to come from a place of genuine curiosity or if the person seems to be asking in good faith I usually try to answer the question to the best of my ability (and sometimes I might still try to answer even if its clear the person is not asking in good faith).
If the question is obviously coming from a place of bad faith or is obvious the person asking doesn't actually want an answer, sometimes I will still try to answer but most of the time I won't even bother.
If the question is accusatory in nature, I will obviously want to defend myself if I am innocent of the accusation.
I suppose I do have things to hide, but I don't make an active attempt to try to hide anything I do or have.
EDIT: As I was writing this comment, you edited the question from "Do you have anything to hide?" to "Do you check the question for boobytraps?"
As a side note, this:
Do you have anything to hide?
is what I would consider a "bad faith question." (And your post edit question is as well considering its original wording in context). This is a question that you are asking as an attempt to hit me with some "gotcha" moment. If I answer "No," then you say I am being defensive. If I say "Yes," then you say I am lying. I may be dumb but I wasn't born yesterday.
You don't actually want to know what things I have to hide if I had any, and you likely don't care. A person would respect other's privacy and not ask out of that principle anyways, even if you were curious.
It's actually to look for ambiguity within the question, and answer the question in whichever way it could logically be taken farthest from the actual intent.
Normally I like to treat questions like telephone calls; ignore them for as long as you can and hope they go away.
I guess that is basically defensive but maybe "passive defensive".
It's what I do to viruses too.
