An IQ test is designed to attract the awareness of a standard norm, rather than someone of who is consciously aware of something else other than common sense. It's one of the reasons we'll lack the ability within other areas throughout life, as well as the reason to 'stupidity' as many would say.
We do stupid 'things', only due to our conscious awareness. If we were capable of being aware of every instance of memory stored within the brain, well, not the brain, I mean, the brain consists of 2 billion (Perhaps an increased amount) neuron cells. However, there are more than 2 billion entities of data accessible by yourself.
However, due to the amount of data, accessing it is an issue. We cannot access all of this data simultaneously. Perhaps if the brain signalled every instance of the cerebral cortex, alongside with another location of which stores the memory (To be honest, I don't believe a single neuron cell could store a scent. Perhaps the body is used for storing data also. Perhaps something we're unaware of), in which case, we'd become aware of the information.
However, we only use a small amount of data daily, we're conscious of one or two thoughts, whilst our subconscious processes the rest.
Anyway, to sum it up, an IQ test can only capture your awareness, and since we're aware of other areas within life, the chances are slim of an IQ test highlighting a given intelligence.
