I totally agree, an your general point can be summed up by the following example. You've got an old guy in the pub- goes in, drinks all day. Not classically intelligent- but through reading newspapers and word-of-mouth has amassed a lot of knowledge, and could probably talk you under the table on many subjects.
I think that is quite a lucid example of what you were saying?
However, yes, how you think is perhaps the defining facet of intelligence- not what you know, or indeed your powers of concentration: originality of thought is what separates the geniuses from the pretty-gifted.
Anyhoo..............we digress!!
