Is there any good research on how general IQ correlates with levels of abstractions people can easily handle?
I understand, that abstractions are different, but here it's probably enough to cover base logical reasoning, set (in math sense) membership and such, maybe some other classification. Also, of course there are situations when language already contains metaphors, which allow people to reason (like "file" can be put into "folder"). My question is more about situations, when there are no suitable ready metaphors ("X" can contain "Y"). (memory can also be a factor?)
The notion of complexity of abstract concept systems is also interesting (if there are several), but my hope is to find an answer for any good notion. Basically, "common sense" logic whatever it is is probably enough reference point.
The idea is simple. Lets say, people with IQ greater than X can understand and recognize part-whole relationship and use that understanding in their work. Then, of course, it is easy to calculate how accessible some system is: IQ has very simple statistical definition (given standard deviation).
I am not a psychologist so I do not quite know even what are the right terms to search. However, my interest is in making software applications accessible to more users and user interfaces oftentimes rely on users handling of abstract concepts. So my interest is pragmatic. Still I think this question is more on psychology side than UX.
I believe IQ matters because if a user can't figure out something in a "moment" (in seconds), system is not usable.
