People are basically random. Some intelligent people are down to earth non-egotists who are willing to take on another point of view, whereas some intelligentsia are people who think they can solve all the world's problems just by writing a sentence on a forum. The sort of people who are in the 12th percentile and estimate themselves to be in the 62nd I would describe as "too stupid to know how stupid they are".
In the middle of those points are a huge, varied and ever shifting miasma of abilities and perceptions. None of which I feel can be quantified.
The difficulty comes when "intelligence" isn't broken down into component parts. An intelligent person could fathom Pi to the 210th decimal place but not be entirely sure how to spell "definitely". I've spoken to teachers and college professors with letters after their names in my Games Workshop days who confidently and consistently wrote the word "emporer".
There's book learning, then there's life skills, then there's wisdom, then there's common sense. As well as other stuff that makes up an individual. Categorising and generalising don't work. Each person is in a category of one.
I am Dave. I can spell "definitely" and "emperor" and write software to measure tunnels, but can't do division without a calculator and can be a bit of a pretentious t*t. Is there a psycho-social category for me, or am I "just Dave"?
