Then this person is either in a mental state (which of course doesn't make them idiots) or joking with you.
If there's limitation of knowledge then that's why this person is asking, to gain more knowledge and not with questions like "what's a car", which i assure you there's no person that would ask this kind of question since one of the first things a human sees in this modern nation is a car since it's part of it. People usually will asks things that haven't been said in schools or not often discussed in general.
And no, this can't reveal you as an idiot. Just someone who has little knowledge on this matter.
People just love to offend someone by calling them an idiot for not knowing something. Which this, in my opinion, makes you an idiot for the offense. (this is not directed to you of course
)
Well, there are a couple of things there, that I mentioned in passing in my previous post:
Given a context, what are:
- The limitations of your knowledge?
- The accuracy of your guesses?
We wouldn't expect someone who doesn't deal with computers or mathematics to know about big O notation, and not doing so hardly makes one an idiot. We might expect them to be able to make guesses about how it functions, given a basic education, and not being able to do so may indicate they're not the brightest cookie in the room, but again it doesn't make them an idiot.
In other cases it's less excusable. I'm reminded of Tina Farrell (23 at the time) who was playing a scratch card game and, upon finding out she hadn't won, said:
"On one of my cards it said I had to find temperatures lower than -8. The numbers I uncovered were -6 and -7 so I thought I had won, and so did the woman in the shop. But when she scanned the card the machine said I hadn't.
I phoned Camelot and they fobbed me off with some story that -6 is higher, not lower, than -8, but I'm not having it."

http://www.mancheste...nfusion-1009701That woman simply does not understand some very basic maths - and it's not particularly plausible that she was denied the opportunity to gain it. We have a state education system - negative numbers are a subject that was, when I was in school, covered when we were six or seven-ish IIRC.
Of course we can make excuses, maybe she had terrible teachers, maybe she's never had to use any maths outside of school and never had any interests to which it's relevant, maybe she had terrible parents... maybe she's not actually as ignorant in that regard as she's appearing and is just trying it on in the hope that people will say she's won anyway. But we've started the reaching game there and in any case, with the exception of the last, they deal more with why she is a certain way than that she is or isn't.
And it's not as if she's particularly abnormal.
More than 15m adults in Britain have poor numeracy - the equivalent of a G or below at GCSE maths
(Same source as earlier)
Though one would hope that a G at least means they get negative numbers.
... And now I feel mean because I came up with a ridiculous example rather than a real life one to
avoid picking on anyone

All that said, I don't particularly like the sense that tends to go along with the idea that someone
is an idiot: That it's some basic quality about their brains. It's not usually a helpful generalisation of things like interest, experience, opportunity and capability.
Relating this back to the original point, however, the concept that seems to be being forwarded in this thread is, under a slightly stronger interpretation, that it's not a desirable thing to appear to be someone who doesn't have an interest in the world around them and to have the basic capability to pursue those interests.
If you assume that someone does have interests and the ability and opportunity to go after them, then there are certain classes of question that they wouldn't be liable to ask in the manner given. They're not going to be ignorant of, at least the basics of, important themes in their world. They'd have wondered long before and found answers long before, (i.e. the context of the question would be different.)
It is plausible that some dirt-scrubbing peasant in medieval-land, or a slave or what have you, has never had any particular chance to pursue an education. However, I don't know how much of that would be true for any of the Warden backgrounds because the Warden is fairly good at fighting, and getting good at fighting requires significant time not spent struggling for food to survive (i.e. it requires a certain degree of wealth) or for your survival to be more directly tied to fighting (i.e. it's your profession in some form or another.) I could believe it for the Dwarven Commoner background I guess.
