I read the article, Sierra, and it is interesting, but not inclusive enough for my thinking.
Some of the books on creativity (which is very difficult to measure by current intelligence standards ) link bipolar illness to high levels of creativity and with high levels of ability in one area,
especially, either math or verbal. (or science and arts, etc.) There is definitely
a correlation between high creativity and bipolar illness, as Dr. Kay Redfield Jamison
points out in her book entitled "Touched With Fire".

For a better understanding of "creative intelligence" I recommend the book "Creativity,
Unleashing the Forces Within" by Osho. I don't agree with everything he says, but
he certainly has an eye for what creativity is. One statement he made is very significant to me:
"it is not a question of what you do, it's how you do it." And "the question is ultimately whether you do it or allow it to happen."

I think the most noted genius may have been Leonardo DaVinci based on his multi-level creativity, and probably the greatest genius in painting and sculpture was Michaelangelo, both of whom had bipolar illness. Many of the Nobel prizes for literature have been awarded to writers with bipolar illness. It's often prevalent in poets, too. My favorite is Shakespeare, seconded by Emily Dickinson and John Keats. Dickinson and Keats were bipolar, not so for Shakespeare, to my knowledge.

Enjoyed this thread very much, but have an appointment and must run.
