Oooh... this article is good. You gained a follower. This is some really good stuff. I haven't been always 100% behind IQ as a measurement. I've met some people that IQ would say were dumb that I thought were brilliant. I've also met high IQ people that I thought were morons. :)
I think the points you hit on though may have a lot to do with that.
I am convinced if we exercise our mind and keep it challenged it becomes stronger. Hard things to think about before become simple, and the new challenges are harder.
I do think EVERYONE has unique things to offer. Though there are a ton of people that do not even try to use what they have at their disposal. Perhaps we can all help to change that.
Thanks. Regarding IQ, I'd say it's an adequate indicator of some things but personality is definitely not of them. Unless you take it as a rule that higher-IQ individuals are typically less patient with others.
Regarding people having unique things to offer, indeed. Each one of us is like a prism which reflects and refracts light in a different way. This is our uniqueness.
